The Resurrection: 94 Firebird Formula

Is DFCO set to reactivate the injectors at a high enough RPM, and prevent stall? As you are well aware, I'm not a tuner, just like to look at the data. Just throwing out random thoughts. DFCO results in engine braking on decel, at least (I believe) with the stock 4L60E. But with the full manual valve body in the TH400 there is no engine braking.

And I understand the age of the brakes has nothing to do with the vacuum booster, but just an alert that in their ancient condition (glazed? warped?) they may take a bit heavier foot to be effective, specially when you pull the car down from those future 130+ MPH trap speeds :D

hmmm, i will check the dfco settings. i believe they are all set the way a normal auto car is set, i just cloned an auto bin and didnt enable auto trans mode for the vss pulses stuff.

there is engine braking in 3rd gear only. 1st-2nd have no engine braking.

as for the 130+mph trap speeds, i hope so lol. i am going to probably go some sort of wilwood in the front. i actually have brembo 4 piston calipers from a 350z in the garage, maybe make adapter brackets and use the 13" rotors for a c5z

I should have added “when downshifting”. Huge disappointment compared to the original T56 when approaching a traffic light next to a Jersey barrier.

Not sure if this was a new part or not but I had an issue on my CC306 manual car where it would stall when coming to a stop. I did the drill mod and it fixed it but I didn't take Alvin's original advice and check the IAC. I datalogged and the IAC was reading as it should so I didn't check it but I found out later during a tear down that the IAC spring was actually stuck fully compressed and was likely the issue all along. Food for thought to maybe pull the IAC and make sure it is actually working.

That's the big problem with the IAC data..... log shows "commanded", but no feedback as to actual. In OBD-2 they tried to solve this with a code for actual idle speed not matching target idle speed, and also commanding the IAC to move, looking for a corresponding change in MAF flow.

You can check the circuitry of the IAC:
