fuel cut

[TheStuartKid]

Alright i will pull the plugs and check them in a day or two when my other ones come in and ill let you know what they opened up to. Quick question: could the new spark plugs possibly stop this problem? because i was reading and false detonation will cause your ecu to pull back power..

I changed the file name for the logs so i will post them here first and see what you guys recommend from there.

 

[etipp98]

e-mailed you back, get me some maf cal logs and Ill recal your sensor and dial down your wastegate

Did the new spark plugs fix the problem?

 

[etipp98]

He was overboosting

 

[speed858]

Thanks Etipp98. How did he solve the issue?

I have the same thing going on in my car.

 

[etipp98]

I had to lower his wastegate duty. You are on stock tune?

 

[speed858]

I have the following: CXracing FMIC, TurboXS hybrid bov, Injen CAI, Hypertech Tune.

I am also monitoring my fuel pump through an ultragauge and it's showing 1600+

 

[etipp98]

You still on stock plugs? They gapped around
. 028?

 

[speed858]

Yep, stock plugs. They are gapped to the stock specs. I had Denso ITV-22 before and it was giving me the same issue so I went back to stock.

 

[etipp98]

Can you see boost with the scangauge?

 

[speed858]

I think there is an option but I haven't tried it yet.

I have seen other users monitor it so I can add that tonight.

 

[speed858]

So I turned on the boost PSI gauge and I haven't seen it overboost yet.

I have done a couple of pulls with it and the best I have seen on the gauge is 10 PSI.

 

[etipp98]

Something is up. Shouldn't be that low on boost and have some sort of cut. This is where an ap or dashhawk would shine in taking some data logs.

 

[chimmike]

Agreed. This is why hypertech is meant for mostly stock motors.

You need to have some sort of way to datalog what's going on. You're either getting load cut or fuel cut.

 

[speed858]

So I have been trying to reproduce the problem with no success. Maybe it was a one time thing.

Will keep you guys updated if it happens again.

 

[chimmike]

when temps cool down, it's likely to happen again
