So I have been tuning my injector scaling and have found the range high to low on my idle and cruise trims, just curious if others see the same range high/low. My idle trim goes from 103.6 up to a high of about 108, then back down to 103.6, then will drop to around 96 then back up to 103.6, but it always settles at 103.625. I logged all day, and saw this. My cruise goes from 98% then up to 99.2%, back to 95% then back up to 98.4%, but same deal 98.4% is where it settles. My ltft correction is -.78%. That stayed consistant, all day. SO CAN I say im DONE???????????????? This was on AMS 780 injectors with the following settings.

Scaling 731.

4.6875 7.03125 9.375 11.7188 14.0625 16.4062 18.6768
3.624 2.208 1.632 1.056 0.816 0.6 0.552

 

Bueller?

 

You're done.

But, to make tuning injectors a LOT easier in the future, use the correct requests and formula, like in Mitsulogger. The correct formula will give you a 0 for a perfect trim, and negative or positive percentage for how much fuel the ECU is subtracting or adding to maintain a stoich ratio.

Also, this will help in using the terms correctly:

LTFT Lo
LTFT Mid
LTFT Hi
STFT

Excellent, Im using evoscan 2.0, so it lists them in that order but based of the 100 value, I have an OBD II scan program that is giving me the ltft correction which is the -.78 %, for some reason the LTFT High on evoscan 2.0 does not move? I posted some pics.

 

The last one on left was 02 feedback STFT. the 100.78%.

 

Anyone wanna check the pics?
