I was so impressed with Garry (The EFI Guy) that I have to relate this story. I have a 93 Mustang 5.0L HO EFI motor in my 67 Bronco, but the A9P (auto tranny version) EEC didn't work at all. After some internet research, I came across The EFI Guy. I pm'd him to see if he still replaced bad capacitors on EEC IV ECUs, and sure enough he does. I sent the A9P EEC to him (in Colorado) on a Wednesday morning from the LA area and received back the next Monday. I plugged it in, and the engine fired right up! I plan to use the auto tranny version EEC because I put in an AOD some years back, and the A9P is reported to have more aggressive timing tables that works better with an auto tranny. I figured I would let the expert fix my primary EEC (and for a reasonable rate).

I also have an A9L (manual tranny version) EEC as a spare. The A9L EEC fires the engine up but is not sending a signal to the #8 cylinder fuel injector. The EFI Guy sent me parts to potentially fix it and answered some detailed questions that I had. He also has a great YouTube video on how to do the capacitor fix.

Anyhow, for those of you with an EEC IV EFI conversion, those electrolytic capacitors are getting pretty old and are prone to failure. Again, thanks to The EFI Guy.

I've talked to him once. Very knowledgeable guy and very gracious with his time. I've heard nothing but outstanding feedback about him over the years. One of these days when I finally get around to attempting the Explorer EFI swap, I will be happy to have him do his magic to my system.

He got me moving a little more efficiently and made a certain little light on the dash go away. Sure wish he was able to get to OCBR to have some fun with us.

I've had the pleasure of working with Garry several times. He's very patient!

Ditto! If it wasn't for Garry helping me along the way with my EFI conversion it would not be running right now. He even shipped me some extra terminals after I had bastardized by relay jumpers. Very good dude! B2

Three statements:
Not enough good things can come to Garry and his family

He has a resource in NH any time he needs it

He knows I owe him dinner next time I’m in his hood

Just PM him. He responded to me within a day for all of my questions. Note though that he does the capacitor replacement (and probably other components if you know which ones are bad), but it sounds like he doesn't have a full test capability to check all functionality of the EEC. You can ask him to provide more details.

Is Gary with EFI guy still in business? If so, how can I contact him. He did a masterful job on the 91 Mustang computer that's in my '75 Bronco Ranger.

Last I heard he was, but he was also super busy with life, liberty and the pursuit of whateverness in the meantime.
If you have his e-mail, go ahead and use it but wait awhile for a response. I believe someone here has said it's easier to get in touch with him via Facebook but I don't know his username. EFIGuy maybe?

Good luck

I got PM from him a couple months ago, was on waiting list for harness/computer re-work. Never heard back, I hope everything is OK.
For me, it's not a problem, because I went Pro-Flo 4 and was going to continue with the harness/computer in case I didn't like the Edelbrock system (or sell it if I did like it). Anyway, he's always been great asset to the community, especially with his YouTube videos.
