Air-con fluctuations. First off set your AC Torque Max Retard to zero over the board (HPT > Motor > Torque Administration > Engine Torque > AC Torque > Max Retard). When you have troubles using a lousy stutter when the AC engages, up your “Idle RPMs With all the A/C on” (equally in gear As well as in P/N) only by 50RPMs across the board. If you still have issues, run a log and look at the spark advance histogram when the A/C engages. Find what g/cyl is referenced at that instant and improve your spark tables in that place to improve stall resistance / stumble (don’t go outrageous With all the timing even though some degrees could possibly be all that is necessary).

If you are setting up a package thanks to collapsed lifters then you'll need to tune using this method anyway.
I had a great deal of leg work to accomplish ahead of this sequence considering the fact that I went from a blown 364 to a Nitrous fed 408. O.K. If You aren't accustomed to the tables in HPT, this may be really baffling. To people who hold the software and may adhere to, Make sure you Insert YOUR Encounters, so this thread could be utilized for every one of the do-it-your self tuners. Gas Management > OL&CL >Open Loop EQ Ratio and established columns a hundred and forty-230*F to = 1 that may command the PCM to established fueling to ~fourteen.7. Clean the transitions by picking the neighboring columns if you want. You'll need to force the PCM to remain in open loop in addition, meaning location the Closed Loop Help ECT vs IAT desk to Max worth (284*File)
I basically commenced a Dropbox to function a tune repository and am content to manage it/maintain it up-to-date.
I obtained into your routine of conserving a duplicate of every new VCM Suite installer Edition after the V2 vs V3 troubles we all went via.
On the flip aspect, In case your IAC counts are maxed at 310 this means your IAC valve is sucking just as much air as it's allowed to and that is truly The one thing holding your idle relatively constant.

I bought in to the practice of conserving a replica of each new VCM Suite installer Variation following the V2 vs V3 challenges all of us went by way of.
Spark advance fine tuning - Make use of the VCM controls when idling to adjust the timing right up until you see excellent MAP (a lot more vacuum). I turned off adaptive spark utilizing the bi-directional controls Along with the scanner (Spark Idle) so I'd a steady, flat timing line and could actually see if there was MAP alterations. Make this happen by visiting the VCM bi-directional controls and disable the Adaptive Spark Command (known as “Spark Idle” beneath the gasoline and spark tab) by really clicking the detroit diesel diagnostic link software “ON” button. Click on again on the “chart display” and observe your timing line…it should be a gradual flat line rather than a noticed tooth pattern, if not, you didn’t disable the Adaptive Spark Management. You may also zero out your Overspeed and Underspeed for the time being and reflash nevertheless it is simply simpler to do 2 clicks while in the scanner. O.K., there'll arrive some extent at which MAP doesn’t get a lot better, and that is a pretty good method of getting into the specified spark progress at idle.
Unique attributes with the flasher are high pace and reliability of operation, assist for a significant..
