Is there a way for me to tune down the AF mixture with out the use of an AFC? If i can save some $ that would be great..

 

Failing MA emmisions?

 

I havnt really gone for it yet.. my sticker is still good. Its more of the stench, the stink is starting to get to me hehe. I replaced the plugs and **** and thought it was getting better... but it really wasnt. It started after the installation of a Pettit Unlimitied ECU

 

What are your mods?

 

Street Ported w/3mm seals
N-Tech Downpipe
PFS Cat-back
M2 Trailing Arms
M2 Control Arms
Pettit Cool Charge II Intercooler
N-Tech Cold Air Intake
N-Tech BMK
Pettit Unlimited ECU
Greddy Profec B
Silicon Vacuum Lines
PFS Boost Gauge
M2 Willwood Big Brake Kit
Reduced Ratio 5th Gear
Pettit Short Shifter
M2 30% Stiffer Pressure Plate
M2 AST Elimination
M2 Competition Radiator
Magnecore 10mm Wires
Bonez High flow cat

 

With those mods it shouldn't smell too bad as long as you have your airpump and it is working. When I had an M2 stage 3 it ran pig rich but I expected that with the generic conservative tuning the "approximated reprogramming" of those kind of ECU upgrades use. But after all the miles of running rich my stock cat and Bonez are now toast and will not pass emissions. I just ordered a Tripoint cat to use for emissions test only and will use the Bonez for general use.

Have you tried putting the stock catback on to see if the smell is less?

If you still can't get the smell down PM me, we can meet and I can put my oz-wb on to see what your AFR is like.

 

cool ill give that a shot and ill get back to ya
