Explorer 5.0 Tuning

[Filgas]

Does anyone have a MAF transfer table for the Explorer 70mm MAF? Also are there any other parameters that need to be changed running the stock Explorer motor with an A9P? Thanks,
Todd

I have it on my laptop at home. Just need to remember to post it. If you are using Explorer ECT and ACT it's possible that the transfer functions are different than the Mustang 5.0 versions, but I've never seen anything that showed it conclusively. I have a Tweecer and am using those two Explorer sensors with stock A9L programming.

That would be great Lars. I am using all Explorer sensors, a frankenharness, EDIS-8 module and A9P. It will have a Moates F3 chip to help everyone play nicely together. I hope for it to be running before the end of the month.

X axis units are volts. In my current delirious state I don't remember the units of mass flow. The above was lifted from the STKR (Tweecer) software, which truly sucks. I started using Clint Garrity's EEC Analyzer for tuning for some time ago, but I haven't messed with it for some time so I'm extremely rusty. I never did finish; I need to download & license his Binary Editor software and dump the bug-ridden STKR stuff completely. From everything I've heard, the Moates hardware is the way to go. I'd buy a Quarterhorse if I was in the market now.

So you are running an EDIS 8 module. Doing an EEC-IV EDIS setup based on an A9xx computer? If so, cool! Welcome to the club! There are a few bits to flip to make it work, and there's a checksum address that needs a particular value. Just going from memory, it's been a long time.
