 +===== Why Adjust The Spark Timing? =====

 +| One of the things that makes understanding timing difficult is that we're talking about 2 different time frames - crankshaft degrees for spark and real time combustion. We light the fire based on crankshaft degrees and engine load but actual burn time is in real time. To get optimal performance we need to light the fire early enough so it has just the right amount of real time to reach max cylinder pressure just after TDC - so it can expand and smoothly push the piston down, this is called MEP or Mean Effective Pressure.\\ \\ Typically, you want max pressure to occur about 7 degrees after TDC. Running too much advance starts the burn too early and max pressure happens at or before TDC, causing "​ping"​ (actually knock). Conversely, not enough advance to the spark causes max pressure to happen too late, producing less power and laboring the engine, making it run hot.\\ \\ The programmable advance maps on the TC88A, and other modern ignition systems, allows timing curves to be altered at any RPM and any load. By trial and error the best map can be found. I didn't know about having all advance in at 3200rpm but that makes sense to me. I run about 32 deg advance but my compression is a little higher than most and compression slows burn time. |

 +===== Too Much Advance Timing? ===== 
 + 
 +Quoting XLForum member, **ASWRacing**:​((https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-electrical/​sportster-motorcycle-electrical-and-ignition/​153340-a-timing-question?​t=1650461+Post#​12))\\ 
 +**A Perspective by Aaron Wilson of Hammer Performance. (June 2013)**\\ 
 +| I've dyno'​ed thousands of bikes over a long period of time, and on many many of them I've dialed in the timing during the process. Advanced it until the power dropped off, retarded it until the power dropped off, and then centered it in between those two locations. I've also played with curves a lot.\\ \\ **I'm here to tell you that too much timing most definitely costs power, and on the vast majority of bikes, the optimum timing is well below the threshold of ping. Running more timing than optimum makes your motor run hotter and puts the pistons at risk and the threshold of ping is a terrible place to put the timing on most bikes!**\\ \\ Most of these bikes, when they have reasonable compression and chamber turbulence (i.e. a squish band), will want their ignition timing set for about 28-30 degrees max advance at WOT. Going past that starts hurting power and making the motors run hot.\\ \\ When you do a performance build, you really should get an aftermarket ignition, because not only can you turn down the timing, you can bring the timing in more slowly. You almost always find power when you do that on a higher compression build! Most of the motors like it so slow that it's not all-in until 4500-5000rpm. On many ignitions, I've found the best power on the softest curve available. For example, the Dyna 2000 curve 4 almost always works the best if the bike under test has 10:1 compression or more. On a Twin Tec TC88A I literally found the best power on my 04 883/1250 on initial 2 / slope 0. That's the softest curve and almost the least amount of timing the module can give.\\ \\ Getting this notion out of people'​s heads that more timing = more power has always been a huge challenge in this business. When you're talking about a performance build, the exact opposite is almost always true. We have a vested interest in seeing our customers get this right, because we don't want complaints of scuffed or broken pistons, and that's exactly what will happen if you run the timing too high, sooner or later. |

 + 
 + 
 +===== Two Timing Advance Systems ===== 
 + 
 +It is important to understand what the various parts do to create the proper timing. Once that is clear, it becomes less complicated to set the proper timing. Of course, with the latest Electronic Fuel Injection (EFI) systems, there are no longer external timing devices, but rather, the entire timing function is programmed into an Electronic Control Module (ECM). So, the following information is related to pre-EFI systems. 
 + 
 +The timing parts consist of a rotating shaft (off the cams) which reflects the position of the pistons, a sensor device to make & break a connection to the coil (such as mechanical points or electronic sensor) and the timing plate (upon which the timing sensor is mounted) which can be rotated to alter the overall timing window. 
 + 
 +The purpose of the spark timing devices is to syncronize the spark to the piston position of the engine. Due to the time it takes to ignite and burn the fuel, the spark timing must be altered to account for the engine operating conditions. 
 + 
 +All spark timing is Before Top Dead Center (BTDC). Slower engine rpms require less advanced timing (sometimes referred to as '​retarded'​ timing). Faster engine rpms require more advanced timing relative to the piston reaching Top Dead Center (TDC). 
 + 
 +Two Types of Advance: 
 + 
 +The old points system used a **mechanical advance** based on weights & springs to increase the advance of the spark timing as the rpms of the engine increased. The weights, by centrifugal force, rotate the timing shaft to alter the specific point when the spark plug fires (spark timing). Even when the points have been replaced by an electronic pickup coil (such as with the Dyna-S unit), the advance timing is still produced by the selected weights and springs. When using this type of advance, you need to synchronize the spark timing to the piston position (flywheel rotation) by **SETTING THE TIMING AT FULL ADVANCE**. It is important that the Full Advance Timing be accurately synchronized (and less important where the '​retarded'​ timing then occurs).((TSB 562A mentions info related to weights & timing - http://​sportsterpedia.com/​lib/​exe/​fetch.php/​pdf-bulletin:​tsb0562a.pdf)) 
 + 
 +On newer, **fully electronic ignition modules** (such as the Ultima, Dynatek or other modules), which do not use mechanical advance mechanisms, the electronic module will calculate (internally) the proper amount of timing advance based on not only RPM but also on intake vacuum in the manifold. For these modules, they must be synchronized by **SETTING THE MODULE AT TOP DEAD CENTER** (no advance). Since the electronic module calculates when to produce the spark, it can use the TDC synchronized setting as a reference for any advance it is programmed to use. 
 + 
 +If you don't have the ability to reprogram your module, the timing curve endpoints can be altered (which moves the starting & ending points) by adjusting the base plate clockwise (for more advance) or counterclockwise (for less advance). Move the plate in very small increments as the tick marks indicate 2-5° each. "If you measure the timing marks on a stock pickup plate, they'​re about .065" apart, i.e. about 5 degrees."​((aswracing Post#18 - https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-electrical/​sportster-motorcycle-electrical-and-ignition/​132853-timing-question-on-a-1250-conversion?​t=1423947))

 + 
 +===== Manifold Absolute Pressure -vs- Vacuum Reading ===== 
 + 
 +Quoting XLForum member, **RacerWill**:​((https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-electrical/​sportster-motorcycle-electrical-and-ignition/​132778-daytona-tc88a-do-your-own-mapping-tips-questions?​t=1422868+Post#​27))\\ 
 +| Just a quick note on MAP(Manifold Absolute Pressure). First, the word "​absolute"​ refers to where zero is placed on the scale. In PSI Absolute, 0 psi is a perfect vacuum and atmospheric pressure is 14.696 psi approx. In PSIg (gauge) atmospheric pressure is zero and a perfect vacuum is -14.696PSIg (equal to 30 inches of mercury, InHg). Kilopascals is the metric version of the absolute measure where a perfect vacuum is zero and atmospheric pressure is 101.325 kPa.\\ \\ The MAP value represents engine load - a higher number represents higher load (more open throttle compared to RPM).\\ \\ For example:\\ Cruising along at 3000rpm on a slight down grade has very low engine load and a lower MAP (kPa) number. If that slight downgrade turns into a steep uphill, you open the throttle to maintain 3000 rpm and the same speed. The MAP (kPa) number starts to climb towards atmospheric pressure 30 InHg (101.3 kPa).| 
 + 
 +{{:​techtalk:​evo:​engctl:​vacuumreadings-map-vs-gauge.jpg?​400|}} 
 + 
 +The point is, MAP readings are the direct air pressure readings and the vacuum gauge reading is the inverse, being the vacuum level reading. In MAP values, the standard atmospheric level is 30, while for the vacuum gauge, 0 is the same level. So a MAP value of 20 (out of 30) is the equivalent of a vacuum value of 10, because vacuum is reading from 30 to 0. A Low MAP value indicates high vacuum and a High Map value indicates low vacuum - The exact same condition is referenced with inverse scales. 
 + 
 +Here's another good reference to understand that the vacuum gauge value and the Manifold Absolute Pressure value are readings taken from opposite ends of the atmospheric pressure range:\\

 +===== Daytona Twin Tec TC88A ICM ===== 
 + 
 +The TC88A Ignition Module is usable on the 2004-2006 carburetored models of the Sportsters. It replaces the stock Ignition Module and utilizes the CKP sensor and the MAP sensor to control the ignition timing. 
 + 
 +The TC88A has dials on the module for selecting pre-programed ignition timing maps and choosing the level of the RPM Limiter. This is accomplished with two dials for timing maps and two dials for the RPM Limit. 
 + 
 +One of the timing dials sets the Initial Timing while the second dial selects the Timing Advance Slope. These settings are explained further in the link below to information about the MAP Files. 
 + 
 +One of the RPM Limit dials chooses the x1000 value and the other selects the x100 value. Settings below 3000 are actually set at 3000 RPMs. HOWEVER - Note: Setting the RPM Limit to x00 will disable the module. **ALSO BE CAREFUL** not to set the RPM Limit above a safe level for your engine configuration! 
 + 
 +In addition to the pre-programmed timing maps (selectable by the dials), the unit can be user-programmed to utilize customized timing advance maps instead of the pre-programmed maps. To use these customized maps, you must have a computer interface, such as the Daytona USB Interface (18014), and the Daytona PC-Link Software, to communicate with the TC88A module.

Note the following information from Daytona support: 
 +  * "From Daytona... Very few engines require additional spark advance below 16 in-Hg manifold pressure. The TC88A uses the 16 In-Hg value for all lower pressures. As further clarification,​ internal cylinder pressure is so low under these conditions (MAP below 16 in-Hg) that maximum spark advance values near 45 degrees are reasonable for most engine applications. Since 45 degrees is the maximum advance the TC88 series is capable of, there is no reason to complicate the advance tables. Even higher advance values yield little benefit."​ ((60Gunner at https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-electrical/​sportster-motorcycle-electrical-and-ignition/​132778-daytona-tc88a-do-your-own-mapping-tips-questions/​page17?​postcount=251#​post4369483))\\

-===== Ultima ​- Nosecone Ignition =====+===== Dynatek Dyna 2000i - Nosecone ​ICM ===== 
 + 
 +The Dyna 2000i (D2Ki-1p) is a self-contained ignition module meaning the timing sensors are built onto the timing plate, located in the '​nosecone'​. The timing rotor cup passes thru the sensors on the back of the timing plate to trigger the ignition module. While this module and the Ultima module are similar in installation & wiring, the selectable internal curve sets are different ([[techtalk:​ref:​engctl01#​ultima_-_nosecone_ignition_control_module|Ultima Module]]).

 + 
 + 
 +These nosecone units can be installed in Sportsters models from the Ironheads up thru 2003 EVOs, including those which originally had mechanical points, external ECMs with a Cam Sensor Plate and those models (1998-2003) which had an OEM nosecone ignition. 
 + 
 +NOTE - The module expects to see 3-ohm primary coil resistance (2.5-3.5) for any of the configurations. 
 + 
 +The Dyna 2000i unit triggers the coil primary circuit - either as a dual-fire system (two sparks per one trigger) or a single-fire system (two separate sparks by two separate trigger signals). The proper coil must be used to match either a dual-fire or single-fire system. The module also has an output for a tachometer and has an input for using a VOES (which is recommended for street bikes) to alter the spark timing during idle & cruising.

 + 
 +An exmaple of using the D2Ki module to replace the 1998-2003 1200S ignition can be seen [[techtalk:​ref:​engctl01a|HERE]]. 
 + 
 +**NOTE:** In the Dyna FAQ((https://​www.dynaonline.com/​faqs)),​ it says this: 
 + 
 +"Can I kick start my motor with the 2000i installed? How?\\ 
 +... Yes, but it will require reprogramming the dead revs back to zero (0). Out of the box, the 2000I has 3 dead revs like a stock Harley-Davidson System. This is also a benefit for high compression motors using an electric starter. The kick must not start on the compression stroke (sensor in the window on the cup). Stopping 'in the window'​ will execute the soft turn off. The leading AND trailing edges of the window must be seen by the 2000i to make a spark."​ 
 + 
 +The 'soft turn off' of the module, when the sensor is 'in the window',​ is designed to prevent the coil from oversaturation from a constant grounded trigger signal. On a points system, oversaturation of the coil (burning it up) can occur if/when the keyswitch is on, the engine is not rotating and the coil is being energized by the points grounding the coil.

 +===== Dynatek DSPT-1 ICM ===== 
 + 
 +The DSPT-1 is designed to be used on the 2004-2005-2006 carburetored Sportsters. It plugs into the stock Ignition ​Control Module harness connector, uses the stock sensors and communicates with the instruments thru the J1850 data bus. This ICM is only configured with the switches and is not computer programmable. 
 + 
 +PSEBYL of the XLForum created a review of the DSPT-1 Module on his 883.\\ 
 +**His thread is here:** https://​www.xlforum.net/​forum/​sportster-motorcycle-buell-motorcycle-forum-general-discussion/​product-reviews/​37408-review-dynatek-dspt-1-ignition-module?​t=73957 
 + 
 +His overview included this info: 
 + 
 +The DSPT-1 has 16 user selectable advance curves in 4 separate groups, using 1 rotary switch:\\ 
 +Group A) 4 curves for stock motors.\\ 
 +Group B) 4 curves for high torque motors (>1 ft. lb. per c. i. @ 2-4K RPM).\\ 
 +Group C) 4 curves for turbo and nitrous applications only.\\ 
 +Group X) The 4th group of 4 curves is described as retard curves, which Dynatek neither defines nor even mentions using in their instructions.\\ 
 + 
 +The first 12 curves are named for their timing value at WOT (for example, 34A = 34 degrees of advance at WOT, group A). The procedure is to use the highest advance curve, in the appropriate group, without pinging. (However, other techs suggest using a max of 28° of advance for built motors because pinging starts happening before you hear it. So, it may be better to use curve 28b or other less aggressive curves.) 
 + 
 +The other rotary switch adjusts for 8 different RPM limits ranging from 6250 to 8500rpm, in 250rpm increments. 
 + 
 + 
 +The following pictures are from xlSleeper on the XLForum.\\

 +Application Note: When used on the 2006 models, the speedometer reading may be off due to the change to HCR gears in the transmission,​ causing the VSS value to be higher than on 2004-2005 models. The DSPT-1 does not have an adjustable VSS value.

 + 
 +| The MODE SWITCH will select the following configurations:​\\ \\ Single-Fire for electric start models:\\ 0 Single Spark, Race Curve\\ 1 Single Spark, OE Curve\\ 2 Multi Spark, Race Curve\\ 3 Multi Spark, OE Curve\\ \\ Dual-Fire for electric start models:\\ 4 Single Spark, Race Curve\\ 5 Single Spark, OE Curve\\ 6 Multi Spark, Race Curve\\ 7 Multi Spark, OE Curve\\ \\ For Kick Start Bikes (uses OEM curve with Single Spark):\\ 8 Single Fire\\ 9 Dual Fire\\ | {{:​techtalk:​ref:​engctl:​sns-crane-hi-4n-ignitionmodule.jpg?​400|}}((Pic from Doug Funny - https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​163044-timing-issues-with-crane-hi-4n?​t=1751610)) | 
 + 
 +The ADVANCE RATE Switch provides selectable curves from 0 to 9, with 0 being the least aggressive ignition timing curve and 9 being the most aggressive (gets to maximum advance quickest). Setting 4 or 5 is thus a mid-point selection. 
 + 
 +The RPM LIMIT Switches will select a maximum rev limit. Using the two switches, it can select a limit at 1500rpms upto 7500rpms. It is recommended to not set the limit below 1500rpms or above 7500rpms. 
 + 
 +Note: S&S bought the Crane Cams company in April of 2009((https://​www.aftermarketnews.com/​crane-cams-back-in-business-under-new-ownership)) and began relabelling the previous Crane HI-4N. Shown above is the Crane version (identified as 8-6100) installed in a '73 Ironhead Sportster.

 +**Discussions of Using the Ultima Module on Ironhead Sportsters (and Kick-Only)**
 +
 +Ultima offers (__as of 2023__) two versions of the 53-644 Ignition Module. The standard version has a 3-dead-rev programming to meet the needs of most EVO engines. This is reprogrammable as needed. It also offers a model 53-644K version which is supplied already programmed for 0-dead-revs for better starting on Kicker models.
 +
 +According to Ultima, the ignition module included in the ignition kit identified as 53-660 (which includes the module, proper coil, proper timing cup, spark plug wires & misc parts) has been pre-programmed to 0-dead-revs,​ which is compatible with kick-only Sportsters. It is a very complete conversion kit.((Jeff in Post#57 - https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​205213-broke-down-and-ordered-an-ultima-ignition-kit?​t=2082634))
