FYI the car is going to run like total shyt, if at all, until you completely retune it after swapping MAF.

 

Yes, I am planning to retune after putting it on.

If replacing MAF doesnt fix the problem then I am totally lost!

 

Will check for intake and exhaust leaks.


Btw, I've concluded that It has nothing to do with the rear sensors because there is absolutely no change in behavior with and without both of them.

Good thing is I can simulate the engine cut 100% of the time thus troubleshooting is easier.

It cuts at 4000+ RPM boost around 0.5 bar.
After cut, the engine doesn't stall but doesn't respond to throttle for 3 to 5 seconds. When it starts to respond after that, the rpm doesnt go above 2.5k.
I suppose that is the limp mode.

Off the engine for a good few seconds and restart to restore. If you off and turn it on immediately, the problem wouldntt go away.

 

I'm having similar prob on my Vortech Z, The street My car was parked on flooded. I moved my car didnt drive it for a few days. Today drove it to work and it chokes at 3000rpm. Besides that it drives fine in the lower RPM I think I have water somewhere also.

 

problem resolved after putting in GT uprev maf.
So conclusion is, my stock maf was dying.

Thanks all!

 

Well done . Thanks for the follow up , good info.
