HELP strange power cut please
Hi to you I need your HELP PLEASE all i haven’t been writing over here because I was busy rebuilding my motor after i destroyed three pistons.
make a story short and the rebuilt is done , i took the car to the dyno and didn’t have one clean nor decent run tell know , my car is a corvette twin turbo LPE last i have made with it was 672WHP dyno jet with old set up.
PLEASE HELP ME , now i am in a big dilemma and i am lost , while the car is on the dyno and i am WOT to do a tune the car starts very smooth and accelerates great all the way up to about 4K RPM and some times 5K RPM and it cuts in a very strange way you can have a look at the video here under at the minute 1:01
You can see that something very strange happens and the check engine comes on for a moment and then disappears ??????????????????

Some thought was to a faulty Crank sensor, some a faulty Camshaft sensor, and some to faulty MAP sensor , when i did the DTC with the HP tuner it showed a miss fire but not permanent HELP
Here in video 2 you can see the tacho meter bouncing at about 5Krpm or so but the car did not CUT like it did the last couple of times but the tach bounced any gusses any takes HELP PLEASE
thanks

The reason I said motor mount, is I've seen engines not completely secured (ie bad mounts) move, and when they move, cause wires to pinch or etc.
In the second video your wideband completely kills off and looks like it would if the motor wasn't even running ---'s.
...And to top it off, this is a new setup for you.

I think you are loosing power somewhere for some reason. I think that's causing the misfire and everything else.
