Thanks Jasper, I’m starting from scratch. I will use the way dieting Accel management system and will work off that. I have a load of aircraft fittings and connectors ordered, going to use breakers instead of fuses. I know what I’m after I just don’t know what to doCan't help you, made my own with a MS3Pro ECU, and Bussmann RMTR Fuse/Relay box.
Is a lot of fun to figure this out on your own. You are 100% in charge of the fit and finish of the loom, and you are 100% in control of what the ECU does.
Down side: steep learning curve.. but so is everything on a GT40
Thanks Mike, appreciate it.Call Dave Walker at Emerald. They will be able to supply what you need and advise on open/closed loop etc.

thanks Shaun, appreciate it. How much did it cost you for the ECU and ignition? Tidy buildHi Jack, Mick at SGT supplies a Motec ECU, I am just fitting mine now which is a little bit of a challenge not least as my Jenvey manifold fouls the MSD Distributor, some careful grinding has taken place. He also has a guy who builds a loom for it as well, mine is a 302 (stroked) got some pictures on my build log here of the ECU
I have the Motec M84 with MSD ignitionNever found out, Mick at SGT said it is possible but was not easy, Paul Bav may know he did his not so long ago, just to me seemed easier to fit and get all sorted before the screen, etc is bonded in, the only reason not to is if you swap a lot post IVA but many do that by just changing the...www.gt40s.com
I think that’s where I shall put mine. I only have one Lambda port on the left collector so I shouldnt need dual loom option. Who will you get to tune yours? I have managed to find one online for £1100 so think I’ll go ahead. Which coil was it that you went for, there are a few options.ECU was about £1,400 with dual LAMBDA
Looms was £595, its well made for sure and seems to fit well I have sited my ECU behind the passenger seat
Thanks Andy I appreciate your input. Do you have a full ECU/disi loom etc that will work for my set up?Hi Jack,
I wouldn’t get too hung expensive & complicated ECU’s If you’ve got a cross-over exhaust system, a twin oxygen sensor will struggle to function correctly as it’s taking information from both banks and won’t be able to discriminate which cylinder to change the fuelling on. A single wide band sensor will be sufficient.
To use this function correctly, it will require calibrating with the engine with on a dyno, with individual exhaust sampling and the ability to carry out fuel trims within the software on each cylinder
P.S. this stuff is also my day job!
With the Emerald it only has 6 injector/ignitor drivers I’ve noticed. Have you found any issues/downsides with running batch injectors against a sequential system?Hi Jack,
I’ve built engines for ‘40s with ECU’s from Emerald and SCS-Delta. Both companies can provide an engine loom with a pre-terminated ECU plug. These are then cut to length to the relevant components. I then add a multi-pin bulkhead connector (ITT Cannon), which makes installation and engine removal a lot easier. Emerald also do a nice relay/fuse loom to cover the functions of coil, ignition, fan & fuel pump control
