Re: Larger MAF for 91 Fox with a supercharger

My knee-jerk reaction is C&L housing for a plug-n-play solution. But that's an old school solution, not a modern solution.

Re: EEC Primer Doc

Have you had a chance to read it over? I've been busy so I haven't been able to do any more mods to it, but that's probably a good thing particularly if there's things that need correcting or re-organizing.

Re: EEC Primer Doc

I don't think this version of the forum code "support" wikis. If it did, I'd definitely have it here.

As for whether to host it on wikipedia, mediawiki, or github, I don't care. I'm new to writing wiki pages. I just know the concept of public wiki pages is exactly what we are trying to do here.

Re: EEC Primer Doc

Perfect. I think this clarifies a LOT of my gaps in knowledge about the EEC. One of the things I just realized is sharing versioned files is an old-school way of dealing with this. The more modern way of handling this is a wiki where multiple contributors can edit the file and each edit is tracked. ...

Re: EEC Primer Doc

I probably need to explain that better ! To my understanding of how it works (someone correct this if it's wrong) When an interrupt happens, CPU sets flag in Int_status_reg, then current instruction is completed. Next, CPU internally does a 'CALL [0x2010+INTNUM]' , exactly like a subroutine call. T...

Re: Stainless fuel filter for E85

I looked up that filter on AutoZone, and it is a canister style, but it's a noticeably smaller diameter than the Rangers use. But that got me to thinking, the early 2000 era Ranger 3.0Ls were FFVs. So I looked up their filter and they use a filter that's the same size as both my Ranger's. Although t...

I wish I had an actual answer for you, but I do believe it is possible. I know guys from the V8 Ranger forum have reused the 97 Explorer EEC in their Rangers, which actually wires in quite well on 95-97 era Rangers given their vast similarity. What I don't know for sure is if those guys actually ret...

That's kind of my take on this as well. But I thought I'd ask the question if anybody had heard of a problem with paper filters. Just using horse-sense, I'd think if E85 was going to be problematic for paper, then they would quit making them for E10 and E15. But I've made assumptions before and didn...

Re: Looking for adx/data logging help!

I moved this topic over to SW Support instead of EECGeeks as this seems more fitting for the issues being discussed. EECGeeks is for the bin hackers to discuss code and firmware aspects of Ford EECs and less on helping people with their tuning and software issues.

Re: Hanging idle after highway cruise

You have a TP or throttlebody issue. Your closed throttle TP voltage starts at .965 and at times in your log it is .8XX. At the end of your log the EEC thinks a TP of .965 is part throttle. I didn't look at the log, but that's an excellent observation that's quite likely the cause. Even in GUFx, th...

Re: Hanging idle after highway cruise

BEB files are encrypted so they can only be opened/edited by BE. And BE will only open/edit them if you have a license AND the also-encrypted definition file that is used to edit the tune. At one point, BE would let you view-only tunes using def files. I don't know if that's still possible or not. T...

Re: Getting ready to tune

The QH and SL work together because they are connected together. So if you are going to implement the SL, you can't replace the QH with a chip. You are married to keeping the QH in place so it can pass info to/from the SL. However that said, I've got a SL and I've yet to actually get it to work the ...

I don't have any experience with either of these. I did try to fashion my own out of a super-cheap pneumatic separator, but it was a huge fail.
