HPT question.

[NITROUS]

I was wondering, now that I have some time to play with HPT, do you disable torque management and purge solenoid, etc...in VCM controls under in the scanner or do you make all of the changes in editor? I have a P0452 code and I was wondering if it's from the solenoid removed or because the purge canister is open and not plugged? This is the only code I have so far and that's strange because the rear 02's aren't even hooked up right now. The only mods to the PCM right now are 4.10 gears added and VAT's removed. Any suggestions on tuning? I'm gonna play around until I get this thing to idle a little smoother. Oh, I also removed the air injection setup. I'm probably gonna get Allen to do me a tune but I also want to learn how to play with this for myself. Any input would be appreciated. Thanks!

What we had to do to get mine to idle was to open the throttle blades just a tad.

Yoiu have to disable add codes in editor, the scanner is only temporary changes. It's gonna take a little driving to throw the code for the rear o2's, its one of those codes that takes a few drive cycles. and it has to go through how ever many drive cylces twice to set the code.

Log STIT (short term idle trims) and LTIT (long term idle trims). Also log IAC counts. I would log the trims in g/sec because its a bit more accurate. Add the STIT to the LTIT and enter the difference in the Base running airflow table and give it some learn time before giving it another run. Once its real close, if your IAC counts arent around 60-70 at warm idle, I would start by enlarging the hole in the TB one size at a time until you get them close. You will have to do the idle trim logging in both gear and in park to get them both lined up.
