Adding an M800 to a car with early ADL dash. Wiring question

[Chris Wilson]

I have a sports prototype with a Formula Atlantic Toyota 4A-GE four pot in it. I bought it from the USA with an all singing and dancing ADL dash that the previous owner seems to have ticked all the options on, like 4 cylinder EGT probes, full data logging from multi axis G sensor, blah blah. The engine is on carbs with an American Electromotive ignition "ecu" which just has a few pre settable advance re RPM points. I have turbo charged the engine, and put it on sequential injection and a single throttle body with a MAP sensor. I have retained the 4 EGT probes. The car has a professionally made Raychem loom in it, mainly going to the ADL and the dashboard switches. I am putting my M800 on the car as the new turbo engine ecu. I don't know whether to try and keep most of the existing loom and feed the M800 some info via Can Bus, from existing sensors, from the ADL, or make a new loom, which will have to be home made due to costs, and the experimental nature of this project, or what? Can anyone advise the most cost effective way of keeping the ADL working, and adding an M800? I am new to this sort of stuff, but I have got my RB26 Skyline engine working fine on an M800, albeit with no ADL installed. I would like to keep the Raychem loom currently in the car pretty much fully intact in case this idea is a failure and I return it to N/A format on carbs and with the Electromotive ignition thing. Thanks!

I would recommend taking to car to a wiring specialist who knows a lot about the engine you are running. Perhaps the engine builder or tuner? Cutting and changing a harness can be a daunting task so please make sure you understand what has to happen. Have a look at our existing dealers listed on the web site, and contact your engine builder.
