Hopefully Jon will see this.

i was looking closly at the new def. file i got from Jon last night.

i found a table in there called.

AFR vs RPM for WOT

it was set to 10:1 until 4k then it was set to 13.5:1, i set it to 12.5:1 across the board (just for a quick test) and went for a spin, did lots of WOT runs in diffrent gears ect (almost got a ticket doing this) but my o2 volts no matter what were between 890-950 across the board. i had never seen this table before in my old def. file, and i just noticed it last night.

anyway, what i am wondering is from someone who might have the 8746 hack, or someone who can tell me exactly what the table controls. i find it hard to beleive that getting WOT fueling could be that easy on our cars, but that one change, put all my o2 volts much closer and more consistant that i was ever able to get them my addusting the 100kpa VE stuff.

any insites into this would be great!

Thanks
John

 

I don't see the title of the table you have but I do have a "wot afr vs rpm." That does exactly what it says. At that rpm, it's trying to the best of it's ability to get your AFRs to those values.
