That's on option too. That's why I want to install the flex fuel sensor to see what happens. because if the ECM is still programmed to use one and does not have it the engine will work poorly.

Yes I did, He says that if the ECM is programmed to have a flex fuel sensor and not having it the will work very poorly. So let's hope it's the flex fuel sensor. Next week it will arrive.

Ever check the injectors? Even untuned with a can it should still run/drive

try swapping another set of plug wires... I’ve had bad wires do the same thing before

Why not hook up a Tech 2 and see whats going on with all these voltages? There MUST be something going on here that makes sense. If it was a a ground issue it would be obvious with the sensor voltages.

I don't think anyone has that Tech 2 where I live. Yes indeed yesterday I just found out that I have a bad ground. So i'm trying to fix it and see what happens.

No local Tech 2 available I'd get a VCX nano for GM and see what that'll do for you. Sounds like you bought it not running. You may have parts on it that require programming or learning for it to run correctly. A Tech 2 or something like it will identify what parts are not set up correctly. Just pulling codes is not going to help much. Have you confirmed that the throttle body is moving on command? It sucks not knowing what was done to it before you got it. Was this the salvage ZR-1 that was burned on the drivers side front?

No the car wasn't burned at all. I actually know now who the owner was. So I have all information right now. All it needs right now it's a tuning and I'm done.

Yes that's her. Well for many guys it may be a "hard" hit but actually it wasn't. Chassis did't had any damage, And I know because I own a body shop. The owner gave the tittle to the insurance company but copart listed the car with that title. And I made contact with the insurance company and the give me the tittle. It's a salvage tittle that I have now. But my problem is already solved since I know the previous owner now. The car made 900 rwhp, NO NOS. So i'm a very lucky guy

So you found the issue with the engine? Was it some part or is it all in the tune?

It's all in the tune. The car had bigger snout, bigger throttle body, port and polish supercharger, smaller pulley, it has a stage 3 cam in it. trunnion head gasket, dashlogic, wideband, rocker arms, head studs are changed too and the car is running on E85. So now i'm contacting Kong performance because he did all the work. getting a new tune and i'm all set man!
