Ignition Timing Table

Creating an Initial Spark Table for Tuning. This is a tool for establishing a baseline spark advance table for your tuning efforts with MegaSquirt or MicroSquirt controllers. It is designed to work in Mozilla Firefox 6.0, though it may work with other browsers. It is based on the 'rules of thumb' presented here Making a Spark Advance Table

These are the base ignition timing tables. These are the lower end of the timing maps that are used. Most of the time the timing is close to these values if the knock control system is active. This table depends on the engine rev number and the cylinder air filling. The numbers inside the table are expressed in degrees before the top dead

Premise - How to setup a spark table to begin tuning Ignition timing makes torque, and torque makes power! At very low loads at barely part throttle most engines typically need 15 degrees of timing more than MBT at WOT for that given rpm. So for example, if you MBT out at 35 degrees at 3k rpm, then for maximum efficieny you should be around 50

The Target AirFuel Ratio Table amp Base Timing Table can then be properly configured amp tuned for any engine. I always suggest taking notes of your current distributor's ignition timing specscurves beforehand, and then program the Base Timing Table accordingly.

Spark advance maps, also known as ignition timing maps, are tables stored within the engine control unit ECU that dictate the timing of the spark plug firing in relation to the position of the engine's pistons. The ignition timing significantly affects engine performance, fuel efficiency, and emissions. Here's how spark advance maps work

The ignition timing table. We have RPM against load on the table axis, the ignition timing number is in the table cell. This is a 3D map. Example of 3D ignition timing map in piggyback ECU. Map contains three dimensions of data, RPM, load and ignition timing degrees.

Much like VEAFR tables, it is important to first scale your axis correctly. Ignition timing, again without going too far into the aspect of advanced tuning, works in a fashion like this As RPM increases, ignition ADVANCES Increases, the spark comes EARLIER in the cycle As LOAD increases, ignition is RETARDED reduces, sparks LATER in

These tables contain ignition timing values mapped against RPM and engine load. Some key elements include Idle Timing Ignition timing at idle RPM. WOT Wide Open Throttle Timing Maximum power ignition timing. Part-Throttle Timing Adjusted for cruising conditions. Understanding ignition timing and spark advance is key to unlocking your

Ignition Timing table in TunerStudio software. You can easily see here how much more resolution we have on our map. Using the increased resolution, we can now program the ignition control to bring the engine to either MBT timing or the knock limit almost everywhere. This lets us extract much more power and efficiency from our engine.

The 10 degrees your set at 'idle', should really be called your base timing. Actually your idle timing value will depend at which rpmmap value you idle at. The calculations are done by increasing the base ignition timing .3 degrees for every value of 1 map. So a lower 10 in map 80-90will increase the timing of 3 degrees. This is the vacuum
