Setting the cold start tables is one of the most difficult things to accomplish when tuning a EFI install, since you only have a few tries a day to make adjustments.

Another problem here is that we are trying to compare maps from different manufacturers it is a multi-variable mix of apples,oranges, peaches and durian.

Some systems uses TOG (Time on Gamma) or injector pulse width in milli seconds... and a decay function for warm up enrichment..Others have tables with temps and percentages, other have tables with number that don't make much sense..

Someone posted a set of tables that are 8 bit values for percentages...

0-255 = 0-100% in 8 bit speak.

Here are some tables that give conversions for 8 bit to %

8bit-percent value conversion


I find that its easier for me to deal with pulse width, and a temp value decay when tuning cold starts/warm up..
