T4M2 initial start up
Posted: 2022 Apr 26, 09:25
Just got a rebuild on the road - using initial T4M2 high performance BIN with the minimum adjusted values as required.
Its a 5.0 HO from a '94 GT, GT40P heads, '93 Cobra Intake, 24lb inj, 76mm TB, and 80mm MAF.
I'm using TwEECer and I'm new to all of this but learning.
Cold start - revs high for ~30 seconds as its supposed to.
Settles down to the 850 rpms in the tune, but hunts for idle dropping to 300-400 before settling in.
Sound when it does this seems like a "sucking" type sound.
When warm - this seems to subside and reduce
Driving - this will occasionally happen when clutching close to and coming to a stop and will occasionally also stall out.
When clutching well before a stop and "coasting" in seems to not happen.
I am thinking its IAC but toughts?
I can post my BIN file if needed.
And no I haven't had a chance to data log and need to upgrade my equipment to try and do this.
I know its needed, but would like to try and trouble shoot past this issue and have it behaving even if not yet dialed in.
