How long have you had the S/C installed? did you make changes to anything recently?

people are going to think im getting paid for this but if you dont have a bunch of money to dump look at this you can look at the factory widebands and everything else the PCM sees its what i use.

So what your saying is that it falls on its face then pulls like a SOB when you get boost?

When looking to get open loop information though, that thing will work will the new style AFR factory sensors?

I ask because if i recall correctly, the PCM stops using feedback form the AFR sensors once it hits open loop. If that happens, wouldn't you be unable to read the AFR in open loop?

But when exactly does it do so? Right after you stomp the gas, mid-boost?
Do you have a boost gauge?

when i stomp on it it goes alright till bout 2-3psi dies kinda then pegs 6psi instantly

And the boost level drops down when it dies, then shoots up to 6psi?

That does not sound good.

yea the pcm ignores the info but it still recieves it i just made a hour long log of me driving outta bordem.

right now im loking at AFR for both banks(2 seperate gauges) both cat temps( 2 seperate gauges) MAF, IAT, coolant temp, rpm, mph, tps, calc. load, spark adv, open loop status, long term fuel trim, and barometric pressure.

ill start another thread about this

get in the chatroom if you got more questions about it
