Did you connect the Apex TT so it can read O2 values/theortical AFR's?
Ok man thanks for your help guys, boost controller is running fine.
What i did....ill put up the readouts tomorrow morning but basically i figured takeing the advice on too much air to the ecu? was a good call so i went and started tuning the AFC in the RPM range that was giving me the problem....
Basically starting to richen it up at eventually max what i wanted to do with no logger, i didnt go above 10% in any rpm range.
When i richened it up +1% at a time it would start doing it earlier in the power band downward to the 4k rpm range so i desided , the sound the exhaust was making sounded extremely rich so i decided to go the other way....
I leaned it out a little and ended up loosing the main "fuel cut" prob. right now it reads around this: (ill have axact numbers tomorrow.)....
This was in high throttle not low. The car is running beautifully and the fuel cut is gone. Does this make sence? didnt i just loose more fuel at those rpm ranges??? i will get a logger and a tune as soon as the cams are in the car as well.
Now onto the boost creep prob......It isnt highly over boosting anymore i have it holding strong at about 19.5 psi and the highest creep i get is around 20.1 to 21.0 psi. However one thing i do notice for those who know about the EBOOST it has a control for the wastegate, i have it set to open at 2.9 psi and if i hold it closed longer there is NO difference.(it should be a ton quicker spool) but it spools quick as shit in low rpms already and i shouldnt be hitting full boost this soon. im hitting full boost before 3k actually in second im hitting full spool at 2600 or 2700 rpms.??????
Wastegate problem?-but the major spikes are gone. and the cel light went off now too.
Thanks again for any help guys its really opreciated.
PS that is a no on the setting the TT for O2 readings , its crap....<----from Apex lol not acurate readings.
