Default boost on NA ecu

has anyone attempted to run a td04 on wastegate pressure on the stock ecu without any sort of ems? i plan on putting my hydra on the car but for smog i need to know if its safe to run it on the stock ecu.

You are obviously hoping someone says what you want to hear. Not safe.

someone correct me if i' wrong, but if hydra is a piggyback, it controls boost, not the stock ECU. u shouldn't run more than 6-7psi on stock N/A compression though.

Hydra is full standalone....and the best way to go if you have one. Eliminate ALL your headaches in one swoop.

Without ANY EM?
Might as well just put a grenade in your airbox and stand back.

just to clarify its not a stock block, its an ej22t block that is in there so compression is about 7.4:1. i just need to know if it will run enough out of boost to pass the cel check. most likely im going to be using a GT30r and the hydra standalone ems with a wrx intake mani and 750 injectors. ill just swap in the stock intake mani and ecu before smog and run it NA to pass i guess

Are you running it n/a already?
At that compression ratio?
With no problems?

Regardless, your plan won't work. You'd be better off finding a shady emissions guy or something.

It should pass, put in the smallest injectors you can and still have it idle.

If you can, just run stock injectors and run the turbo with the wastegate loose/open for emissions.

Ah ha.. a little more information has surfaced now.
So, the OP isn't looking run a car with stock EM.. just run it, drive down the road, and pass emissions. Right? Now were getting somewhere.

Like red said above.. that's a pretty good option. Jimmy the wastegate to stay open, and you should see little to no boost, assuming you stay off the skinny pedal.

As for will it run well enough to pass the CEL check... that's a good question. I can't help you on that one. My guess would be that yes, it should. But, that's just a guess.

Yes I am running it na currently
Yes it runs fine but is really low on power which is causing it to get very bad gas mileage (aprox 16-18) other than that not having any problems running the car this way. I am pretty set on putting the 30r on the car ill post a writeup in the bolton forced induction when its finished

The extremely low CR is what's making it run so poorly. It's just too inefficient right now.

Get some air into the cylinders somehow!
