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.
ICY1.BIN
EFI-SD4X_180409.xdf
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.

Another newbie here, with probably a lot of the same questions that other neophytes have. I'm setting up my stuff by following instructions on the "Getting Started" page: http://www.efidynotuning.com/started.htm

I just installed the QH into my stock A9L computer, installed TunerPro5 RT with the required USB/serial driver onto my lap top, and it sees the QH.

I downloaded the A9L.bin and GUFB_56k.xdf and GUFB_56k.adx files from Moates' web site, and loaded them into TP5 RT.

I was trying to figure out how to read the stock tune from the computer, just to get a reference copy. But the starting page says that's not necessary. Does this mean that the stock tune should be identical to the A9L.bin file? What if I wanted to read a tune off of a computer anyway, what would I need to do that?

Next thing I looked at was enabling RT data logging. The instruction says to enter "Univ" in the finder dialog box. But this does not appear to be in the standard bin file. So which bin file should I get for that feature?

The long term plan is to rebuild the stock 33 year old engine with bigger stroke, heads, cam, and intake (plus MAF, TB, and injectors to match) and tune the EEC to handle all of that so I can get as much streetable power as possible and still pass California smog checks. I'm sure it's been done hundreds of times by folks in these forums, but it's all new to me.

thanks in advance.

correct the a9l bin is the same as your ecu has. Vehicle identification didnt come about until obd2 with eec-v. So reading the atock tune will not have any other specific info like vin number or pats code that eec-v would have. Thus theres no need to read the stock cal.

nothing here applies to using the original gufb strategy

I have a gufx strategt which is my own code for the fox ecus. You can download it as well as the a9l2 bin from the downloads section here on this site.

Anything you find on the internet anywhere else other than here will be outdated. Always best to use the most recent files.

the getting started write up has specifics on how to read the stock tune its all in there. Not that you need though.

GT8790, you went down the same rabbit hole I did so I understand your confusion. On the download chart under "Strategy ", scroll down and download the GUFX xdf. Then move right and hit "Stock" which will download a bunch of stock bins including an A9L. Then move further right and download the A9L2 [2019/05/16]. That will provide you with the A9L2 base calibration and also the Universal adx.
Use the GUFX xdf and Universal adx with either the stock A9L or the A9L2 and you will be good to go for learning to "tune" and datalogging. At least I think so...it seems to be working for me.
I loaded a stock A9L into the Moates to get a feel for what's what. Ran the car, watched the "Dashboard" and, now that Michael set me straight on the "Universal" adx, will play with datalogging. Then it's on to loading the A9L2 which I'm setting up with the parameters for new injectors and a Cobra MAF.
Download and read everything Decipha has written...at least twice.

Good luck

Thanks Guys, I found the files, and hope to try them out soon. The laptop that I had set up for doing this had a failure, and I'm trying to get it back into working order. If I can't, I'll have to get another one to do this.
