i have a couple of friends with s/c'd 2zz's, here is what was said via msn...

do you know how evil and pmag tuned w/ piggyback?

is it all open loop?

i seem to recall evil had some kind of trick to fool the maf or ecu or something...

Yea..

The ECU goes into open loop when you go WOT.

So he has the TPS signal run into a relay.

And then the emanage outputs a faked TPS signal.

When it detects boost, the relay fires (digital output), switching the tps signal from the actual tps to the faked tps value from the emanage.

Putting the car into open loop.

The other option is to tap into narrowband and fake the o2 reading to have the factory ecu richen the mixture.

the tps sounds like it works.
i found a function in the fic to switch the o2 map to be switchable with boost pressure. now just need to test drive to see how well it works!
it worked sitting in the parking lot, i was able to drop it down to 12.2 at idle.
so it is tunable, now just trial and error to see how well it works.
