20de+T rich smoke

[daninchainz]

Plus T’d my 20de to see how it’d go until my 20det is ready, I’ve basically just bolted on the turbo, intercooler and 20det red injectors, has an adjustable fpr at 40psi and walbro 255 and stock 20de ecu. 

Engine was pretty healthy prior to being turbo’d but now it smokes like f*ck and the smoke just stinks of fuel vapour. It’s insanely rich and I’m just wondering if anyone else has come across this issue? Are the injectors really pumping in that much fuel that it smokes out the garage with in 20 seconds? Or should I keep stock injectors in with boost at 7psi. Worried about leaning out.

It's because of larger injectors on a stock ecu.

Untuned and the mixtures are wrong. No surprises here.

You can't just slap on bigger injectors on. At least run a RB20DET ECU so the fueling it somewhat in the correct ballpark.

You're commanding the same pulsewidth on bigger injectors, what do you think is going to happen?

Imagine a garden hose you open and close for 2 seconds.

Now go use a fire hydrant and open and close it for 2 seconds.

Is the flow the same? No.

Yeah thought this would be the case. 20det ecu has different timing so that won’t work. I’ve put DE injectors back in for now, runs fine with those. It’s just gonna be a hack till other motors ready.

Actually a RB20DET would run better as it has less timing in it.
