    M10 1.8L Base MS tune anyone???

    Hello, I have a 1984 318i with the M10 that I did some upgrades to.

    *Ported an Polished heads
    *Port matched intake
    *Bigger valves with a 3 angle cut
    *Mild cam
    *Upgraded valve springs N rockers
    *4-1 Long tube headers to a 2.5" collector
    ​​​​*2" straight pipe exhaust with a 2.5" Borla muffler
    *Stock bottom end
    *Stock distributor with V.R sensor for crank position/ignition timing
    *Aftermarket GM 3 wire Throttle Position Sensor
    *Aftermarket GM 2 wire I.A.T Sensor
    *Stock E.C.T Sensor
    *Megasquirt 2 v3.57 board running my injection and ignition
    *Innovate motorsports Lc-2 wide band O2 sensor controller w/ Analog gauge


    I was wondering if anyone had a semi similar or just a stock M10 base tune for me to start with so I don't blow anything up when I try to turn that key for the first time. I appreciate any and all POSITIVE informational feedback and /or tunes for me Thanks!!

    this was my NA tune for a stock m10b18. You'll have to adjust some things like the trigger settings, required fuel, and o2 settings, but should get you started.

      Amazing, thank you, what did the tune produce with your setup?

        93whp/90ftlbs, on an un-opened 200k mile engine, with questionable compression on cyl 4. I don't think I have the dyno graph anymore, unfortunately. It pulled about as expected for a sohc 1.8L and much better in the mid-range compared to L-Jet. As most m10 318 owners know, you can feel the timing come in between 3k and 4k on L-Jet. The car ran 16.88 @ 80.5mph in the 1/4 and I believe 2240 lbs at the time.

        The car had an aftermarket cat and ansa muffler, along with a simple cone filter. Also I forgot to mention that the engine didn't have AC or power steering and the water pump and alternator were under driven a little, with a 4.5" crank pulley.
