Right about 6,000 RPm she starts breaking up and hesitating. But thats where the knock comes in at. So gods of tuning, where is my problem? Bad 02 sensor? Needs more fuel? Mods= b16g, stock pump and fuel system,Frount mount intercooler,boost@15psi,2g TB,2g manifold,3in apexi turbo back,hacked MAF,Ram clutch,Fidanza flywheel and vented stock BOV(yea yea i know but i dont seem to have any idleing problems,was like that when i bought car)

So what do you guys think update the fuel system?

 

[JohnTSI]

What is your fuel preassure doing at 6K is it falling off? DO you have a AFC? IF you do tune it add fuel see what happens. IF you are saying its breaking up knock doesn't genrally cause a car to break up it will pul timing and lose power. IF those where wide band reading we could say yeah its running out of fuel but a narrow band is crap. Add some fuel up top and see how it changes.

No afc yet, working on getting one. As I was saying right about 5900-6000 it will lose some power/hesitate/studder. Whats up with my 02 loosing all the voltage ??

 

[rowlex]

You are probably maxing out the fuel pump, rewire it may help, installing a 190lph will help.

From your log I also notice you are running lean the entire pull, I'd stop getting on it so much, or turn the boost down. Your o2 volts at WOT should be way closer to .92v.

It also probably wouldn't hurt to check your base timing, it appears your timing when/before boost hits is already at 15* it should be closer to 10...

 

[JohnTSI]

Tuning with the stock 02 is a joke. I have had a BRAND new mitsu o2 sensor read .76 at wot when the car was running rich. Hell Right now at 32 psi it reads .82 with 1550 ETGs 0 knock sum and 19 degrees of timing at WOT throttle pulling like a rapped ape. You cannot use it tell tell if its lean or rich unless its falling off.

John, so do you also agree its a fuel delivery issue and time to go with a 190? Safc? 550's? All of the above?

 

[JohnTSI]

I would deffinetly get a bigger pump and 550's would not be a bad idea. If you do not have a fuel controller get one. Then log again and see where it gets you.

If me asking this question in your thread bothers you pm me and I will delete it. Although I do think it is a good question. I notice on your tps it says 96, I logged my car again today and found that mine is at 96 at wot, can anyone else verify this as normal?

 

[markgholland]

It should be 100%. Adjust it and you'll be alright.

Actually on my log its 99.6, i'm not going to play with it for .4, I would probably break something .
