Problems: Turbo kit& MPI Piggyback

[igdrasil]

Thats cool!

Little Beavis was here in PR last week and he helped me with the tunning. Car was running so damn great with his tune. Then I found something interesting. We almost blew the engine. Yesterday I discovered that we were injecting on only 2 cylinders!!! (aditonal Injection).
We didnt notice because we were only tunning for 5psi and the stock injectors were shooting most of the fuel and the aditional came on to make a balance.

I did noticed @ day because I was hearing a bit of pinging thru the microphone setup.

This could mean that we had 2 pistons running HOT and now could be a bit bad.

Igdrasil, that IS interesting... Keep us posted. So you are saying that the stock injectors crapped out?

EDIT: You know now I know what you are talking about. You are referring to the J&S lighting up only 2 cylinders? The same happens to me.

I dont have a J&S but I need one for sure.

I knew that because when I opened the hood, I saw 2 disconected injectors (aditional injector harness).

The engine is still running because the stockies were throwing most of the fuel, but Im sure not enough for those 2 that were not having the extra fuel with the extra injection!

Will do a leak test, dont know when.

Im going to do some normal driving from home to work....

As far as visual inspection, there still no cracked piston so far.
