Re: Modern day potential of J3 devices beyond TwEECer and QH

Ah yes, the upper 10 bits, now you have bumped my memory. See page A5 of EEC Pocket Reference guide. For R4 & R5 Bits 0 to 3 are the AD channels. Bits 4 & 5 are read as zero's Bits 6 to 15 are the AD result... Correct me if I'm wrong, but that is because you read all the analog inputs from the same...

Re: Modern day potential of J3 devices beyond TwEECer and QH

...One thing jumped out when I did the bench testing. Purely watching AD counts on the software side, all Analog channels changed in steps of 64ADC... So for whatever reason, the hardware is putting the A/D counts in the upper 10 bits of a 16 bit word as opposed to the lower 10 bits. That's why it ...

Re: Modern day potential of J3 devices beyond TwEECer and QH

Interesting stuff coming from this discussion. But I have something that I need clarified. This is specific to the GUFx era EECs since that's what I have def files for. Both HEGOs have a def file conversion formula as follows: (5.12-(X/12800))/2 Most 0-5v sensors have a X/12800 conversion formula in...

Re: Modern day potential of J3 devices beyond TwEECer and QH

That's true. HEGOs produce a voltage, usually no higher than about .9ish volts although I guess there's some out there that reach above that??? Mine have only ever hit in the low .8v range when run hard rich and most of the time, not even that high. As for Wideband O2 (aka lambda) sensors, yes, they...

Re: Modern day potential of J3 devices beyond TwEECer and QH

The hego sensor max is around 1V I believe... That's correct. Sometimes ford multiplexes binary inputs on the hego pin. Clamps the analog channel to 5V when some switch closes. It's a minor point but just so I understand, when you say HEGO pin, do you mean EEC pin or processor pin? What's confusing...

Re: configure files fail to initialize

My last experience with stack traces is that he obfuscates the code, which makes guessing at what the exception is trying to say becomes more difficult. However because of that, he's also going to need your version number so he can reverse the obfuscation himself.

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.

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.
