throwin this up for a buddy... its a full bolton evo with FPRED w/o2 dump, 1000cc, the good NGK spark plugs, ign amp.... we had a base tune done with meth and the meth controller stopped working so he sent it back to the company...

I tuned him for pump gas at 23psi, when doing WOT it seems that it dumps extra fuel in there and it chokes on itself when he upshifts...

im thinking its a scaling problem, but would like ur input

here is his scaling map

886

4.7=3.312
7=1.680
9.4=1.152
11.7=1.008
14=0.888
16.4=0.552
18.7=0.240

 

evo9 btw

 

anybody?? this car pulls soo hard but we cant shift!!

 

Is the BOV/DV working OK?

This seems odd to me, as the usual problem is going lean when shifting. Have you data logged this?

 

it could be lean, im an inspiring tuner, i get the jist of it but i cant get my computer to log afr's.. however, his BOV has issues! its the stock metal one, when u cruise it howls.. hmm, that actually makes alot of sense concerning this issue.. i'll look into it.

but back to the log, when he sticks the shift and it chokes, the timing jumps to about 30degrees while its "choking", then it pulls like normal, cant recall the afr's
