I don't think its the ecu. I cleaned off a couple of the spark plugs and it tried to fire, albeit roughly and unsuccessfully... New plugs on order.

If the plugs are totally fouled, it's possible that this is the problem -- good luck.

I'm still leaning towards bricked ECU and or wrong ECU ROM flashed on there (assuming that can even happen -- don't know if it would just reject it if not a match).

Wrong rom isn't an issue unless it is an auto rom on a manual or vice versa By that I mean it would still start if the NATS is happy or disabled.

The ECU controls the spark. spark timing and fuel delivery.

But if it was bricked, then wouldn't everything just cease to function?

If "bricked" means totally destroyed then the answer is yes. The suggestion to swap it out may be the only way to know for sure.

Update:

I changed out the plugs for R35 GTR plugs and it started right up. Lots of white smoke coming out the exhaust (not coolant, I know what that smells like, damn subarus) I think it was just all the built up fuel and such from trying to get it to start the last little while.

I had it run for a minute but right before I was going to shut it off ( 10 seconds or so ) the idle started to sound like it was just getting a touch rough.

Told ya

I'd throw away that Jtran tune and get a custom tune at a shop

So just fouled plugs then? That's good news!

But why did they get so badly fouled? That means either a tuning issue or something is wildly off on the boost levels your ECU thinks are being run, so it's skewing pig rich under load.

His problems started before that. I completely agree that custom tunes are far superior but keep your bashing to facts

:iagree:


Actually, wasn't he unable to get the car to run on the safe map JTran sent up there? So that had zero to do with his problem at all and the issue was fouled plugs and whatever fueling issue caused that kind of fouling?

I know us engineers don't read too well but :iagree:.

"I write prints I don't read them" - every bad engineer ever

I'm thinking of maybe putting it all back together. Putting some new fuel in it, taking it out and giving it a bit of a workout, get some nice high temps in the cats and such. Thought?
