Got a GSR motor with a turbo kit. Using chipped ECU with a baseman from phearable. Problem is my #3 cylinder is flooding with fuel.

Using 880cc precision injectors no resistor box. Car shoots out lots of fuel. Pull plug on 3 and it is soaked in gas. Changed injectors still the same problem. I pull the injector plug while cars running and no more gas coming down the down pipe.

I'm stumped on what the problem can be because if it was resistor box wouldn't it happen to all of them? I'm guessing its either the ECU or the Distributor.

Any help is great thanks

 

basemap on bigger injectors than the base map is set up for????

hmmmm tune man thats all your going to here on this site

 

Also want to point out if I put the injector plug on #4 then #4 floods with gas. So I know the cylinder is fine.

 

Yea it's one of those maps. I want to make sure that its firing right before I go and get it tuned. I tried other chipps too and same problem.

 

It isn't that harr to figure out. You only need a few things for an engine to run. If you spark is good and the injector isn't stuck open, it most likely is the tune. BUT for it to be that bad, that basemap would have to be WAY off. Most likely you have another issue.

 

Did you try putting a noid light on that plug? If it pulses that injector more than the others you prob have a weird driver issue with the ecu. Try another one.

 

Yea that's what I thought that tune would have to be off. I have a feeling it's the ECU but wanted to see if anyone had this problem that can chime in.

 

If the injectors need a resistor box then chances are you blow the ecu.
Also check wiring to make sure the ground control isn't grounded out to the body or another injector.
