Hi everyone I'm new to Kpro and recently started having trouble with my car. Its an '02 RSX-s with a custom turbo kit running about 8lbs. A few days ago my car started acting up, Whenever i go full throttle it will jerk violently and the RPMs will go all over the place. The only thing different in my DL's is the injector durration is through the roof. If the problem is not in my tune my only other guess is my fuel pump is going and im losing fuel pressure.

Also I dont have a stock primary so the datalogs are using and AEM UEGO

Thanks,
Travis

If you don't have a primary o2 then you cannot use lean protection. IT will only work using the factory wideband sensor.

Then what would be the cause of my car feeling like hitting fuel cut and my injector duration being so high?

It is shutting down becuase of the lean protection. Turn it off.

I tried turning it off didnt solve the problem :(

Post the new calibration and a short (under a minute) datalog showing the problem.

Will do as soon as I can tomorrow

Heres the new ones for today. I think the problem may be caused by my fuel pump going out giving me low pressure and hard starts.

That is not under a minute. What is the timestamp where you experience the problem?

The worst case of it is between 5:00 and 5:10

I don't see any problem at that timestamp.

check the injector duration. I dont think it is supposed to be that high.

check for a vacuum leak, do you have a fuel pressure gauge on the rail/what does it say, someone whas having trouble sort of like this and he ended up having a bad fuel filter.

I had similar problem, try calibrating the TPS!!
