This is what I have in A0008 and this is leaned out some and does not go to as high an ECT as the original. It does got to a higher ECT than the table above. Give it a try.

-40*C 1.4
-30*C 1.4
-20*C 1.35
-10*C 1.3
0*C 1.271
10*C 1.214
20*C 1.175
30*C 1.125
40*C 1.075
50*C 1.00 and up to 110*C
110*C 1.064 and up to 140*C


What is your Commanded AFR in {B3647}. Is it the same in {B3649}? To do AutoVE both tables should be the same. Also do not set it to 14.63 or 14.68 or STFT may be enabled. Set it to 14.7 when doing AutoVE. I believe {B3647} enables STFT when set to stoich. Not sure if that means 14.63 or 14.68 or the one set in your tune in the Menu Edit...> Properties...> Display.

What injectors are you running? You may want to have a look at {B4005} Small Pulse Adjust. This is an adder and will be added to injector on time when very short injector on time is commanded (between 0 - 4ms as set in {B4006}.

I set my a0008 to stock and recopied the first couple rows of my VE table from an old tune. was a little rich this morning. So That must have been the problem.

Sounds good. Nice when something you try works out.
