Friend of mine has had issues with a tune thats been developed for his car so has decided to take things into his own hands and plunge for EFI, I should be on some sort of comission.
Anyway before he takes the final plunge he is going to borrow mine to do some logging to check out how everything is. All is set up to log but in preperation for possibly tuning his car I am setting the tune up for AutoVE.
His car is an LS2 with an E40 ecu. He has complained that since the return of the car that fuel economy is shocking. His tune is set to run in OL SD mode, maf and o2's disabled. LTFT, STFT all disabled.
Looking through the tune I saw table b0141. By reading the description it appears that if you are in Open Loop mode, that this is the table that commands the fuel levels when in gear?
In the tune, this is currently set to 1.46 AFR or 10.0 EQ, is this standard for this table? I have compared this to a hsv tune for the same engine and they appear the same, however, the HSV tune was running closed loop. So I guess this table, as it is only ever in OL should be updated for warm running in OL mode (similar to 3605 on the old GenIII ecu's?)
