adjusting fuel for gearing...



Hey guys this is what i got.

these readings are at WOT from diacom.

1st gear 4175 02 reads .876
2nd gear 4250 02 reads .894
3rd gear 4225 02 reads .942

How the hell do i adjust the fuel curve?

1st and second are good but third is way rich.. all i can do is add-subtract fuel by rpm, can't do anything for gearing....

those readings are taken off the same run.

at 4650 in 3rd i was at .956 02 voltage!!!
but at 5650 in 2nd i was at .916! (same run)

trying to get a good curve of .9 all the way but 1st is always leaner than second, and second is always leaner than third...

should i tune for 900 at second and let 1st be a tad lean and third rich or what?

thanks,
Shane
