    Use airload in the scanner. If you don't have that than you can use math to figure it out. Use one of HPT default maths. It would MAF cylinder airmass. Take that number and divide it by your engine...

    Not to start an argument or anything and I'm saying this with no offense and disrespect... At least they give the option to use serial or AC/EGR input without the pro feature set. Even if you...

    I want to add that I know there is way more to it than spark but my thinking is start simple, prove the theory, and if it works bring in things like VCT and such. My guess is there is so many...

    Well that's reassuring 😭. Okay so if torque tables = 100 and driver demand input is 100 than all is well. Torque tables =100 and driver demand input is 60 you'll get IPC errors which would...

    You should be able to tune it without issues as long as they didn't put a password/lock on it. Have you pulled the file from the car yet? Only other issue I could see is if whatever software they...

    I need a sanity check lol.

    If driver demand is greater than engine torque what happens?

    If driver demand is lower than engine torque what happens?

    Thanks

    Look at the AEM gauges. Their is no controller as the gauge itself is the controller. It only has one output but that's all you need since the gauge doesn't need it. It's easier to install as...

    It's a 2004 F150 5.4 3V with thumper cams, manly Pistons, IMRC delete, long tubes, etc. To be fair, when I requested...

    I can't really complain about them not adding it. They've always been really responsive to me as well and added about 15 parameters on the tune file so I'm thankful for that. The used SCT only cost...

    Makes sense. I didn't have time to try it anyways. HPT doesn't have IPC torque error or engine brake torque for mine and has no plans to add it when I requested them along with others. So I have...

    Just for clarity sake. The column table in your tune should never be adjusted to the values calculated in the spreadsheet? Just change the actual inverse values with your logged airload?
