    Microsquirt M20 Stroker w/ITBs (Fuel, Spark, No Start)

    At my witts end currently on getting my engine build finally running.
    Some preliminary info about my situation:
    • M20B27 Block, Overbored
    • High Compression CP Pistons
    • 885 Head Swap
    • M50 Injectors
    • Racehead ITBs
    • Stock Exhaust Manifold
    • Stock rotor and distributor + stock single coil

    Im using the Tunerstudio with the V3 Microsquirt + Microsquirt harness tied into the C101 and the C191.
    The crank pos sensor wiring has a 10K resister in parallel.

    Im getting spark, fuel pump prime, im getting an uninterrupted tach signal. I can hear the pump relay kick on and the injectors clicking as im cranking, but no start. Not even a gurgle of combustion. I pulled the plugs after cranking, and it doesnt seem like theres much fuel on them if any. Fuel rail gets fuel and pressurizes as far as I can tell.


    So I'm thinking its my tune. Ive never used tunerstudio before and never used an aftermarket ecu before. It seems like its something simple that I'm missing that I just don't know about.
    Im trying to attach my tune and my composite log to this post, but its saying I cant upload .msq or .csv file types. Any help is appreciated.


    Edit:
    Here are download links of the files from my google drive:

    jakeb might could help. He doesn't always get on this forum. But he does have a website call Classicdaily.com. But I'm also sure that there are plenty of people on here that can help. I've recently went standalone and I'm also learning as well.
