Who is the EFI guru?

I remember someone here being a vendor for a variety of EFI packages but I can't remember who it was.

I'm looking at resurrecting my home made EFI intake and plopping it on the 543. I was never satisfied with my old outdated Electromotive TEC II system and would like to find a self learning port EFI system with timing control that suits my needs. I'm sure my old 120 lb/hr injectors are no longer serviceable but they'd be too big anyway. My 1700 cfm throttle body is a bit iffy but I bet I could make it work on an engine that big. I'm not sure if I'd have to dig out the old 60-2 trigger wheel or if the new stuff uses the distributor for rpm signal.

Anyway, whoever you are, poke your head up so we can talk bidness.

If you want to go port injection then your best bet would be a Holley HP ECU. 120 lb injectors are at least double what you'll need on that 543. You can control timing if you use a Holley dual sync distributor. I think a dual sync distributor would be less of a hassle than the 60-2 trigger wheel. There are also 36-1 wheels available for Mopar engines. I don't know anything about your throttle body, It might work but you would need to confirm that all of the sensors are compatible with the Holley ECU. It might be easier to buy a new Holley throttle body, they aren't super expensive and they are plug and play. Rich at FAST Man EFI is a Holley dealer and a Mopar EFI expert.

we've got a 36-1 trigger wheels setup that integrates with our serpentine belt kit. then top that off with a cam sensor bushing and run a jeep cam position sensor on the big block. then you can run whatever ecu you want. i'm still a big fan of the megasquirt setups. you can get their gold box thats preassembled and fully tunable. goody has had good luck with his, plus theres a ton of features on the box you may or may not need. tuning your going to want to have it on a dyno anyway. you can tune the megasquirt kit with tons of support from online forums, the megasquirt also has datalogging capability, you can record your tables and then run them through an iterator which will tell you what to adjust, tweak the tables and drive again. rinse repeat. maybe a little more tedious than the self learning systems but this is basically what the self learning systems do. you just dont see it.

I've got an original Ford Cobra twin 57 mm throttle body as well as this monster.



Those 120 lb injectors were pushing it on the street for the turbo setup but they gave me plenty of options for fueling. No doubt I'll need to step down to something in the 60 lb range. I like the FAST remote IAC and Ford TPS with the GM plug on it. Maybe I could use those with whatever system I end up with.

The Holley system is definitely on my radar. I'd much rather have a system that more people know instead of the obscure Electromotive setup. It was feature packed but worked backwards from everything else out there and very few people knew how to help me tune it.

Feets call, Rich at FAST Man EFI is a Holley dealer and a Mopar EFI expert.

He is only on here occasionally, so calling him is best.

Holley is the easy route for sure they made some nice stuff. If your like me and need the cheap route then something in the Megasquirt Lineup is more labor intensive but has massive savings. I had to build the ECU and Harness for my setup but my $$$ per feature is incredibly low and reliability has been perfect over nearly 6 years now.

I would go with the smaller throttle body, its hard to modulate small amounts of throttle with a big single blade like that accufab but it won't be hard to swap between the two to test them out.

I second the vote for Rich. He really knows his stuff and did a great job on a 6.1 Hemi with 8 stack injection that I built. Rich Nedbal-EFI Expert

Very nice.


I spoke to Rich yesterday.

I sent Rich an email through his website two weeks ago - on a Saturday morning. I hit "send" and walked 70 feet out to my shop. When I got there the phone was ringing and it was Rich calling from California. I'm in Ontario, Canada !! It wasn't even an urgent issue. You don't get better service than this !!

Doing my 51 myself with Microsquirt.

Well, my son and I, it'll be his car when I kick on so I want him to be up on it.

Not like there is a lot of institutional knowledge out there for putting EFI on a 51 Plymouth still running the original flathead.
