    Need some advice on a OEM ecu for non stock (OEM) application.

    I have a 1990 Toyota 4runner 22RE turbo with mt5. Have a small KKK turbo on it, LS injectors, LS coils, GM IAT, Toy TPS, Toy VSS, Toy CTS, WB O2 (or NB), crank sensor (custom 36X wheel with Ford sensor, could be changed to 24X or any other tooth count), Ford IAC, Toy dizzy with 4X wheel and 1X wheel with Toy hall sensors.

    I have considered Emtron and Holley but the $2k price tag will go a long way towards hardware. I also have a 0411 GM pcm/harness in hand and I've read some threads that are sparce on details that the pcm can be configured for 4 cylinder operation.

    Question- would this be a good choice or are there better choices out there- spend more on a flexible ecu and save on tuning or less on ecu and spend more on making it work.

    To my knowledge GM did not use the '0411 with a 4 cylinder, so it's unlikely a V6 or V8 operating system could be easily modified to run a 4 cylinder.

    GM used the E37 ECM on 2007 - 2011 GM 4 cylinder engines (2.2 / 2.4 liter),with coil on plug ignition. With some advanced fabrication, the E37 camshaft and crankshaft sensor inputs could be configured to the 22Re, allowing an E37 to run a 22RE with coil on plug ignition. Both EFI Live and HP Tuners support the E37 ECM.

    Attached is the '0411 CKP_CMP waveform relationship (V8 coil on plug ignition). I wonder what the E37 4 cylinder CKP_CMP waveform relationship is for coil on plug ignition?

    Hello David.
    Still waiting for a new WB controller for the Chev- ordered the wrong 4.9 sensor instead of a 4.2 and instead of taking the shipping hit, ordered a new controller to match the sensor- they are very reasonable these days out of 14point7.

    Does the E37 require a 58X wheel?
    Just planning here- if there is a suitable unit, gives me time to source ecu and harness. Is the MS3 at all in the running here, I don't know what the cost is but I do know it is very flexible.

    I have not researched the E37 ECM or 2.2 / 2.4 liter engines to know what the cam / crank signals are.

    Hmmm, I did not get a notice of reply.

    Truck is not running. No high voltage to the distributor at this time- this is a stock Toyota hall sensor on the 4X reluctor and an added Toyota hall sensor on the 1X reluctor. Also looking at Microsquirt as well... but the 0411 is interesting. Crank has a 36-1 toothed wheel and Ford sensor- tooth count can be changed.
