Unless you physically remove power from the ECU, there is no
need to clear a power code. Same for TB adaptation, but I'd
do both just to be sure.
On drive by wire cars, the throttle body step motor needs to
be 'matched' to the potentiometer that is the gas pedal.
So closed is closed, full throttle is indeed full.

"I cleared the (power) code and adapted the TB" was mentioned in a
previous email. I am currently driving in chip mode and have not reset
anything. figured this would not need to get done until stock ecu was
placed in. Can anyone elaborate on what "Adapted the TB" stands for?
Also are any additional codes generated bc I did not erase power loss
code in the beginning.

Here is the thread from our forum:
If it does not work then here is the quote
"Well, tonight has definately been interesting. It
seems that GIAC still has some problems to work out
(will figure it out on Monday I hope ). At any rate,
the car would randomly die on me tonight. I could be
driving, idling, whatever... Didn't really matter.
Seems like it is a fuel pump issue or rather a
regulation issue, but I don't know what would be wrong
to be causing that. Funny thing, once I switched back
to stock chip everything was just fine...
What little I did get to drive the performance was
amazing.. Amer and I were able to do a 3rd gear
roll-on @ 60mph. He is stock with an APR, and I stock
with the GIAC. We got on it and I walked away..
Performance difference between the two seems pretty
amazing; however, it would seem that I am compromising
reliability. Going to give Todd @ AWE a call on Monday
and see if I can find out what's going on. I'll
probably have to send it back and go with APR, but
with the performance I was getting I HOPE i get to
stick with the GIAC (if I resolution can be reached).
At any rate, I'll let everyone know what happens. It's
a shame to see a seeminly good chip work like a$$."
"Well, I emailed Todd at AWE last night around
midnight. Got up this morning and I have already
recieved a response from him. He said it sounds like a
flaky socket. SO, he said on Monday that he will
overnight a new ECU!
Just think that's GREAT customer service and wanted to
let everyone know."
Ever since he got his new chip everything was fine
never had anymore problems
Hope that helps
