Re: Why auto disassembly is tough

Actually, I was thinking the project would begin as a legacy EEC-IV/V J3 port solution and morph from there. These are far simpler EECs that control simpler applications with the J3 device being something like a Beaglebone. The Beaglebone's AM3358 processor has 200MHz Realtime coprocessors on them t...

Re: Why auto disassembly is tough

Just out of curiosity, does disassembling this stuff get easier as the processors get newer? Expand the thought beyond EEC-V into modern processors. Does Ford still hand-author assembly in these things or have they embraced C/C++ which would make disassembling them, presumably, easier and more predi...

Re: ecc analyzer?

If you didn't datalog MAFv and only datalogged the MAF values, then EA can "generate" the MAFv column on load as long as your tune's MAF curve is entered into EA as the "first" MAF in the list of 3 curves shown. To get EA to do that generation, you do have to tell it to on the settings tab.

Re: is my computer fried

In the GUFx defs, there's a scalar that defines the "minimum" MAF voltage to consider the MAF good. Well when you replace the MAF, that voltage has to be adjusted for the new MAF's "minimum" voltage. My guess is your strat has something similar.

Once you've gotten that working, then you can start tweaking at the tune with the things you mentioned. As for the dail...

Re: is my computer fried

I'd bet there's nothing wrong with your QH. You simply need to get a valid tune written to it so that the EEC's processor is being served up valid code. Once you do that, my guess is it'll work just fine.

The 11-18 ohm is a standard high impedance range. So you are fine there. The question of whether USCAR or EV6 gets more complicated.
