Hi everyone,

Looking forward to getting a rusEFI and have a couple of project cars (MX5 vvt, 300e W124) to try it on.

Thanks,
Grant.

Ah ok,

My youtube channel, I haven't posted much in the past year or so.

I plan on developing a turbo kit for the NB MX5/Miata.

I also make trigger wheels to suit the M103 and M104 Mercedes motor so it's easier to install an aftermarket ecu.

I have a 3 axis cnc and lathe, Mainline dyno in my workshop.

Hello and welcome,

Have you found the wiki yet? If not here's a link.

3 axis CNC, I drool.

My RUSEFI arrived today.

Now to get busy wiring it into a M104 W124 300e-24.

Any advice on connectors?

I have a Deutsch connector kit.

If your OEM connector is not the same as the OEM harness, and if you plan to re-use the OEM harness, you could make an adapter harness. Commonly you can get the pig tail form a salvage yard, either ebay or I see it at this link.

If you have an OEM salvage ECU, you can remove the OEM ECU connector, then solder each of the above pig tail wires to the OEM harness connector. To make this more robust, it is common to make a break out PCB board, similar to this.

If the engine currently runs, you can typically patch the signals to the Frankenso, and migrate one cyl at a time. Basically connect one cyl to the frankenso, as well as the RPM, TPS, etc signals. Then tune such that the one cyl is operating like the others. Once you have it running like that you can then migrate over each other cyl one at a time, eventually removing the entire OEM ECU. See below PCB which can be helpful with this kind of approach.

If you have a running engine and if you do this kind of pig tail adapter approach, one good feature is that you can always unplug this effort, and re-plug in the OEM to make sure the engine is mechanically sound and working.

This thread might give you some ideas. This was a test mule that @ once had.

ok thanks, the original injection on these motors is CIS mechanical so I can't use the OEM wiring.

I've already wired it up and had it running with a Haltech elite750 using DEKA 60lb injectors but I would like to get it to run with the RUSefi.

I'll give the local wreckers a call and see if they have any cheap ecu's that will suit.

Looks like I buggered up by not ordering it with the connector and pigtail.
