 | 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. | | 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.

 | 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.

 +===== Two Timing Advance Systems ===== 
 + 
 +It is important to understand what the various parts do to create the proper timingOnce that is clear, it becomes less complicated to set the proper timingOf 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.

-| 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).\\ \\ Engines require more advance under load at a given rpm and also need more advance as rpm increases at a given load. | +| Just a quick note on MAP(Manifold Absolute Pressure).

-(I think that should be 'less advance under load at given rpm'??)+ 
 +{{:​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 MAP value of 20 (out of 30is 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:\\ 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:\\

-And, you can't mix a single-fire control with a dual-fire coil nor the other way. That's why they make two types of control modules and several types of coils. 
  
-You can set the Static Timing using a multimeter (or test light) connected between ground & the trigger point on the coil for the front cylinder. Rotate the engine until you are on the compression stroke for the front cylinder. Then open the timing hole and look for the FULL ADVANCE mark on the flywheel, placing it in the center of the timing hole. Turn on the ignition. Hold the center rotor in the FULL ADVANCE position, fully counter-clockwise so the weights are at their stops. Now loosen the mounting screws and rotate the Dyna-S timing plate clockwise & counter-clockwise to find the exact point where the meter shows full voltage (or the light is lit brightest). Lock down the mounting screwsThe timing should be set very close to correct(Using a timing light for Dynamic Timing at 2000 RPMs is more accurate.)+Crane 8-1100 HI-4 Fireball Dual-fire Nosecone Ignition\\

-The Ultima Ignition Unit (53-644) is very similar to the Dynatek 2000i product (although the programmed curves appear to be different). It is a self-contained ignition module meaning the timing sensors are built onto the same 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. 
  
-These nosecone units can be installed in pre-2004 model Sportsters, 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. 
  
-The Ultima unit triggers the coil primary circuit ​either as a dual-fire system (one triggeror a single-fire system (two trigger signals). It also has an output for a tachometer and also has an input for using a VOES to alter the spark timing during idle & cruising.+(Also see S&S HI-4N Ignition Module, previously Crane 8-6100)

Then open the timing hole and look for the FULL ADVANCE mark on the flywheel, placing it in the center of the timing hole. Turn on the ignition. Hold the center rotor in the FULL ADVANCE position, fully counter-clockwise so the weights are at their stops. Now loosen the mounting screws and rotate the Dyna-S timing plate clockwise & counter-clockwise to find the exact point where the meter shows full voltage (or the light is lit brightest). Lock down the mounting screws. The timing should be set very close to correct. (Using a timing light for Dynamic Timing at 2000 RPMs is more accurate.)

 +===== S&S HI-4N Ignition Module =====
 +
 +The S&S HI-4N is a nosecone ignition module.

 +
 +| 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 - http://​xlforum.net/​forums/​showthread.php?​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. 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.

 +===== Ultima - Nosecone Ignition =====
 +
 +The Ultima Ignition Unit (53-644) is very similar to the Dynatek 2000i product (although the programmed curves appear to be different). It is a self-contained ignition module meaning the timing sensors are built onto the same 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.
 +
 +These nosecone units can be installed in pre-2004 model Sportsters, 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 Ultima unit triggers the coil primary circuit - either as a dual-fire system (one trigger) or a single-fire system (two trigger signals). It also has an output for a tachometer and it has an input for using a VOES (which is recommended) to alter the spark timing during idle & cruising.

 +===== Motogadget M-Unit Blue =====
 +
 +\\
 +
 +This unit is designed to replace the power control device on your motocycle. It does not provide engine spark or timing, so you must supply (or keep) that part of the motor control devices (points & mech advance or ignition module & timing sensor, coil, etc). Their main website is https://​motogadget.com
 +
 +The m-unit operation (and the manual) is updated regularly so it is important to know which version you have to know what functions are programmable. The manuals are not dated, so pay attention to the version & S/N references.
 +
 +Take note that most input switch connections are expected to activate the signal by grounding the input. This may not be the way the stock switches are configured.
