Make sure you save a version beside the edited, incase you want to revert back. 3. Locate and select the "Speedo" tab 4. revise the tire dimension 5. revise the gearing if needed 6...

    4.88 gear question... How to calibrate the speedometer?

    I notice that too, that the PID format varies from year to year after reviewing some of shared tunes. Newer model has more comprehensive tuning tables than my 2008.

    08 LX570 Misfire and stalling (No Codes)

    Close thing i could relate is the weird check engine when i use the Harrop manifold AIT. Before i usually gets it when after a quick stop from a freeway restroom break or long traffic on hot summer days. I did the experiment switching back and forth between the factory and Harrop AIT. For sure...

    08 LX570 Misfire and stalling (No Codes)

    KRR, Unfortunately you need to tune the correct injector values and the MAF rescale. If you confirmed that the fuel pump is working properly? What tuner software did they used to program your ECU? One suggestion to baseline the setup, return the bigger pulley, stock injectors and the stock ECU...

    ECU Calibration for Supercharged Land Cruiser

    Yes took my truck Carb Connection. I feel they specialized on GM cars and trucks but not Toyota. Maybe its a blessing they left the stock ECU rather than doing something that could have resulted to more catastrophic engine failure. Also it force me to learn the HP Tuner, the ability to make...

    ECU Calibration for Supercharged Land Cruiser

    ECU Calibration for Supercharged Land Cruiser

    Not an expert on this mater, just able enough to do and observed. Hopefully someone can share their knowledge. My understanding is the more accurate the air temperature measurements before it goes to the cylinder chamber the better the ECU will be able to determine the exact fuel and timing...

    ECU Calibration for Supercharged Land Cruiser

    That's exactly what i did collecting files and comparing them. Are you using the stock air box? Also the AIT that is located on the Harrop charger manifold is susceptive to heat soak (can cause Check Engine) specially when highway run then park. Try using the stock factory MAF/AIT and see if...

    Actually, i was surprised to learned about this problem and experienced it. I took my truck to a well established tuning shop nearby who is particularly HP tuners as their main platform of choice. They have corvettes, camaros & other GM cars parked in their parking lot waiting to be tune. They...

    ECU Calibration for Supercharged Land Cruiser

    HP Tuner will do the job, does the Magnuson comes with uprated injectors? I have a 2008 LC with Harrop Stage 2 (with uprated injectors). I personally did the tuning after i could not find anyone familiar with Toyota. Most tuner that use HP Tuner only cater to American cars. Familiarity of the...
