Idle Air Flow vs. Coolant Temp vs. (Gear & P/N): This table is used to determine the base airflow (in g/sec) for the IAC/ETC control vs Engine coolant temperature. This is used as a base setting (or startpoint) for the adaptive idle routines and also the base IAC position when the vehicle is moving.
12/19/2017 · There is no gear or P/N for the desired airflow, you have to do an idle scan in gear, and a separate scan in P/N. There is a STIT+LTIT in gear and a STIT+LTIT in P/N graph. … open folder icons. For example to get his graph file working in your layout, download it, put it in C:Documents HP Tuners VCM ScannerGraphs, open your scanner, Right …
GM – HP Tuners, GM – HP Tuners, GM – HP Tuners, GM – HP Tuners, 10/7/2017 · Under Engine > Idle > Airflow, there is the Adaptive Idle Airflow, in here you can set the limits for the AC offset minimums and maximums. For large cams, you might need to set the AC Offset Max/InGear to 4 g/sec (you can change the units by clicking on the unit next to the box).
7/30/2018 · I am wondering if the Base Running Airflow > Idle Airflow table interacts with the MAF Calibration>Airflow vs. Frequency table? More specifically, if there was a mismatch between the two tables at a given frequency or engine RPM at the same g/s value could that cause fuel trim problems in the MAF calibration? Application is a 2007 LQ4 with a P59 PCM.
Gen IV E38/E67 Idle control. In this document, we will go through the basic steps to get your idle control setup using VCM Suite. This procedure can be used with aftermarket camshafts, superchargers, turbos & conversions in both Auto & manual configurations. Please read this document carefully and use at own ri, Idle Airflow Mult(P/N) Alcohol vs. ECT vs. ERT: This is the idle airflow multiplier in relation to ECT and engine run time(ERT), when in Park/Neutral. Alcohol applications only. Idle Airflow Integrator Time Underspeed: The time rate at which the integrator will adjust the idle airflow to correct the idle RPM, lower numbers are faster.
The derivative control is designed to make fast corrections to the Idle Airflow when large deviations from the Desired Idle RPM over a short time occur. The derivative control also works in conjunction with the stall saver function to attempt to prevent engine stalling. The derivative airflow uses a fast and slow filtered RPM signal and then …
– Hey guys, Andre from High Performance Academy. welcome to another one of our webinars where today we’re going to be talking about idle tuning in GM vehicles using the HP Tuners software. Of course if you are tuning GM vehicles on another platform, everything we’re going to talk about today will also port across quite nicely.
HP Tuners also offers a number of speed density mode enhancements that improve the VCM’s ability to run in speed density mode and also provide additional parameters allowing for forced induction tuning (2bar/3bar) in speed density mode. MAF Calibration. MAF Airflow vs. Output Frequency: This table is used to calibrate the MAF sensor. The MAF …
