weird fuel maps with bnr32 rb20det-mec

Post by supersayianjim »

okay okay okay, so heres my problem. Iam trying to get a smooth fuel map with this thing..

rb20det
nismo fpr
650cc d-werks injec
wally fuel pump
z32 maf
front mount and 3"catless exhaust
hx30 turbo at 22psi max

so even when i load a new map the target afr looks alright. but the raw values appear to be backwards(ON A BRAND NEW MAP,UNTOUCHED).. the idle and lean readings are 189-192, and further up in the powerband they drop to single digit values like 2,6.

anyone know what the deal is or do i have just bad luck?? i mean i can take fuel out of the hifgh areas but why should i have to add fuel in the top end??

Cells with high value numbers are used for O2 feedback / closed loop cruise operation, is that what is confusing you ?

i guess. the graphic map is going up with the smaller numbers getting into the red. so iam not supposted to change the cruzing numbers smaller and the wot numbers larger??

View the maps with Filtered Values rather than Raw Values and it will look more like what you're expecting.
