Hi Dave, did you make progress with the LM2 wideband as an input for the MPVI? ...regards, kevin

Two weeks ago, i decided to take a chance on the first question. I set "Engine-Fuel-General-Reference Angle-Intake Valve Open" to 356 degrees. This is where the cam card says the intake valve (#1...

Hi Kevin, thanks for using HPTuners hardware and software. Maybe you've already figured out the answers to your questions without assistance, but if not, here are a couple hints:

1. ...

I did as you suggested, mstang_man, and copied the MBT table into the Borderline Knock table. The engine runs well, wideband shows close to lambda in closed loop. Long term fuel trims are close to...

I'm more interested in low RPM torque. I chose cams that affect 1400-5400rpm, which is where i do all my driving.

1. Looking at the MBT table, you set all cells in the .90 load row to 25*...

I'm going to take your advice and drive and datalog it for a few days. If my fuel trims look good and the AFR is at lambda in closed loop and .81 at WOT, what's the next tuning step? ...regards,...

I have a couple questions regarding my current tune.
1. Engine-Fuel-General-Reference Angle-Intake Valve Open: 348.50 Does this mean when the valve moves off the seat, or when it's open...

Thank you for the MAF numbers! What year is that Mustang? My MAF Airflow vs Voltage numbers are very close to the ones you posted. Should i continue to adjust the table, or is it close enough now...

I reviewed my datalogs, and my LTFT numbers were consistently subtracting around 3.5% fuel at all MAF counts and RPMs. Then i looked at the only Ford tunes in the repository that were anywhere close...

I have another question about VCM Editor for my 2004 GT: In "Engine/Fuel/Oxygen Sensors/LTFT Bank vs. Cylinder #", cylinders 1-5, 10-12 are in Bank Number 0, and cylinders 6-9 are bank 2. Unless i...

I appreciate the reply, mstang_man, and thanks for the worksheet and instructions. You suggested i put the car in closed loop, then hold the rpm at each maf count and record the stft to use as a...

Thanks for the note, mstang_man, unfortunately VCM scanner doesn't work reliably with my car. I've been datalogging with my LM2 wideband and my Diablosport I3. I'm overwhelmed with information from...

I'm looking at Engine-Airflow-General. Under MAF Calibration, in the Airflow vs Voltage chart, there are two columns. The column on the right is airflow (i'm using lbs/min), but the column on the...

Thanks for the reply, yes, i really do want to tune it. ...regards, kevin

I've put about 300km on the car since the injector update. After disconnecting the battery for a few hours, my long-term fuel trims are reset and now steady between 0-5 +/-. In closed loop the A/F...

I decided to add the injector data to the tune. It appears that WOT pulls now show a maximum of 0.81 lambda. My first impression after one drive is that the engine idles better. It was stalling at...

Hello, HPTuners, first-time member here. Nice to see a supportive community like this.
I have recently built a new engine for my 2004 Mustang GT. Nothing exotic, as this is
a daily driver for 9...
