just wanted some opinions on these log files the one afr is 14.7 across the board the O2 sensor was cold i think.

the set up.
expandSofar i have S4 front cover,oil metering pump. Series 5 rotor housings and lower intake manifold, series 6 eccentric shaft,rotors,counter weight, flywheel, upper intake manifold. Greddy throttle body elbow, Racing Beat 105 psi oil regulator, and HP oil pump, Atkins solid corner seals, 3rd gen corner springs, Rotary Aviation super seals and springs, stock s5 turbo, custom intercooler and black pipeing, Tial 50mm blow off, ss auto chrome turbo back exhaust, microtech lt-10s

 

just did another run
this time everything was warmed up and i was in 3rd gear inbetween 1 through 50 and it started chuging and bucking really bad i have been getting it alot ive tried so many things to get rid of that but if i stand on the throttle it goes away

 

Have you re stabed the timing and set the timing to TDC?

 

Do you have any kind of wideband? Those injector times look VERY high for low boost. What injectors are you running?

Edit...though it looks like you staging settings are probably set too high. You need to low the RPM and MAP stage point a little.

 

for a wideband just went out and bought one got the aem uego and for the injectors im running stock on the primary and 1000cc venoms on the secondary. The settings are just about stock in the mapping other than idle but i have some lowering to do also i have a medium street port on the motor.

 

It looks like you are putting way too much fuel into the engine.

I also suggest you lower your stage point to around 2000 RPM and 2" of vacuum.

 

too much fuel ok your right the afr is 10.5-13.9 about 12.7 at idle and 10.9 under boost under light throttle 11.4-11.8 do you think i should lower the mixtrim insted.

 

Don't miss with MixTRIM. Tune it properly instead. MixTRIM lowers fuel over the entire fuel curve.

Actually, 10.9 under boost isn't too bad, but it's richer then necessary.

11.4 under light throttle is WAY too rich.

 

all right i just got it fixed it runs sooo much better i used a poor/crazy mans dyno. I let my woman (she can drive and now wants a duplicate car) drive it on a 2 mile road around my way the lap top on my lap, adjusting and more adjusing $40.00 more in gas and got it all good up too 7k man that takes time. The temp is better 82/84c and soo much more power less boost spike 10psi afr is 11.0, 6-7 psi 11.5, crusing and light throttle 13.9, idle is like 13.00. Wow the power doesn't stop i think i can rev even higher lighting the tires in 3rd gear w/dryrotted 205/60-15 pirelli's on the rear that are now bald,belts showing. peak power feels like @5500 rpm thats where they start breaking loose. All the poping/chugging i was getting from it was too much fuel afr was under 10.00 at times before the help. Aaron cake THANK YOU for the help

Aaron Cake the center dash gauge mount you have who,what,WHERE? I have been looking all over for one.

 

Glad things are working out. Amazing the difference getting a decent fuel curve makes...

The center dash pod is an APC gauge pod that I cut up. I just trimmed the bottom to fit the FC dash.

 

thank you im making one this weekend
