New to EEC-IV tuning

Unread postby junkiestunts1 » Tue Dec 03, 2019 10:08 am

I have a 92 F-150 with 331 stroker, 30lb injectors, howards cam, 195cc intake port heads, long tube headers. orginal ECU speed density still installed
I am wondering if I need besides the $250 quarterhorse kit from Moates to get going (do i need F3v2 and jaybird?)
I also noticed that when I startup tuner pro rt with the stock ecu file for the 89-94 F-150 that it freaks out with some strange values. example instead of a normal value of 0,1 or 2 for some "features" like transmission control, it had a value of over 200.
I am starting with the following base files.
more questions to follow i guess.

you have to match the calibration to the strategy your ECU is using. What you are seeing with the weird values is a strategy missmach. You can use that strategy XDF, just use the matching base tune that is on the download page and upload that to the quarterhorse.

But you only need the quarterhorse for now. Once you get your vehicle dialed in for good, best practice is to burn a F3 chip and install that in place of the quarterhorse. But realistically even though its not recommended by moates, the quarterhorse can be left in place for the long term. Only thing that may happen is if the on board battery dies on the quarterhorse, you will loose your tune, with a f3 chip that wont happen.
