83807Thank you Bill. I have read the link days ago. Today I try "writing entire" with no success. I attach the latest HPT file loaded in the system. Please, take a look and let me know your comments....

Thank you both. I will try the write complete (I don't have other option). Please let me know if any new thoughts come to you,

Hi, I need to disable VATS for my Firebird 98 V6. I did set the DCTs P1626, P1629, P1630, and P1631 to option 3, but still the car don?t start. What else is needed. Is there a procedure like discone...

I have a Pontiac Firebird 98 3.8 V6 with the security light blinking on the dash. I did set P1626 and 1629 to "No Error Reported". P1630 and 1631 were already on "No Error Reported". I flash the...

Vortec, thank's for your response. I use a different method to avoid MAF use, but the VE tables are pretty close (around 1 to 2 % of error), anyway if I have to hook up the WB again I will follow...

I buy HPTuners to enjoy the experience of tunning my car and I like to do things by myself, but I'm not a car technician and never before have a tuning experience. My car is a 02 Pontiac TransAm WS6...

Thank you!

I'm having problems with my laptop and I decided to reinstall the OS, how should I do to not loose vehicle license's and everything related to hptuners?

Ivan

I used same formula but without multiply by 100 and adding two decimal places.

Shift points can only be adjusted in automatic transmission. In the speedo area for adjusting the speedometer, at the right, there is a selection box for automatically adjust the shift points at the...

Your numbers are right if the height is correct, be sure you use the unit conversion under tools menu to calculate the height. Did your friend use the "Auto Scale Transmission Tables" when adjusting...

thebeewantsboost,

If you want to return your car to original tune go to the bin repository and search for your model, year and transmission, there you will find a stock file for your car. You only...

Thank you Bill. Hsve a happy new year!!!

Bill, did MAF OS will be the same as the original OS, except for the RTT? If I go with MAP OS, the MAF sensor have to be eliminated? I already switch to MAP OS, can I switch back to original or go to...

I understand that MAP 2BAR or 3BAR are for force induction but my car is stock so how I know wich one to choose between 1 Bar MAP or 1 Bar MAF OS?

This adjustment maybe different from car to car even on the same brand, but inyour Grand Prix its probably the same as my V6 Firebird, so..., in the unit conversion calc filll the tire size calc with...

Well, finaly I solve it myself.

I'm trying to follow Greg Banish method as explained on his DVD. My wideband (ATX NGK) is working and got the reading in the table display, but two other PID's don't work, Commanded_Lambda and...

Multiply 26.6 (actual tire height) by the tire/gear number in the speedometer section, that is your gear ratio. Now divide the new tire height, 28 by the gear ratio. Enter that number in the new...

Well I'm no expert but at crusing 14.7 14.5 AFR is ideal, going higher is lean and WOT for naturally aspiratedshould be no less than 12.5, and that still safe for your car.

Ivan

Thank you Bill. This weekend I ordered a NTK wideband, a HPTuner upgrade to Pro, and the DVD from Calibration Success. Lot of money... I hope thats all to do the tune all by myself.

Ivan

I understand that I only need the wideband sensor not the device with the display for the HPTuner program. But if I don't buy the display device, how I will calibrate the sensor? Did HPtuner have any...

Hi, Im a rookie but here's my opinion. The htp file show that you have done several changes in MAF, PE and spark advance. If the air intake is stock, the MAF don't have to be changed. Wrong PE to add...
