hi there recently upgraded from ms2 diy unit to a ms3 pro unit. Cant seem to get the car started. cars a 1.6 turbo with 550 flow force injectors from nigel. i think everything is correctly set up settings wise could be very wrong. i have fuel cant seem to get a spark though switched plugs still no spark. car is still on factory ignition setup. ill attach current base map and short log of it cranking.

Your MS is shutting off due to low voltage. Currently you're cranking at 5.8v.

Noticed this after posting this. Charged battery now have spark. Can’t get it to fire yet though. But one step closer. Thanks for looking at that though.

Now post a log with decent voltage.

heres log number 2. itll crank then catch and stumble, thats about all that happens. Have verified i have spark now. fuels there. feel like im missing some sort of settings so much more stuff in tuner studio with ms3 compared to muy old ms2 unit

Get a better charger, it's at 17+ volts.

Start by turning your cranking advance down to 0 under ignition options. Its really hard to read the log, since you're at your cranking rpm for a tenth of a second each time. If that's it catching and stopping, the cranking angle change should fix it. If that's you letting go of the key, you'll have to crank it longer for a decent no-start log.

so when cranking it will act like its losing communication with ecu the instantly come back while still cranking.. possible grounding problem? never had that problem before. also sometimes while cranking it will open my waste gate and pop. obviously not normal.

You're still having some sort of battery issue, it's registering 5.5v, but seeing 157rpm, so that's probably a communication issue. As to why, I'm not sure.

Would recalibrating battery voltage maybe fix it. Think I calibrated it when getting it installed but may have forgot? Battery right now is at 12.5 but tuner studios is showing 16.3

Twice i've had "just weirdness" happen with battery voltage showing unreasonable values, and despite trying to correct it the 'right' way, I've found that reflashing firmware actually fixed it.

I went to battery calibration and did that now it’s reading correctly Atleast the gauge is on tuner studio. Not sure in a log yet. I’m sure I’ve flooded it by now.
