Your spark advance drops to 11.8, the "Crank:Y" indicator is lit up in red, and most importantly, injector pulsewidth goes right to 4.8ms when you're turning over, which I'm assuming is what you've got in the CrankPW table. (This is a bit too low for 315cc injectors, IMO, but it's close enough that something should be happening.)

Try reversing your ignition wires. This is probably the most common first-time mistake on new MSs, and one that I've made a time or three myself. It's possible that you may have the 1/4 and 2/3 ignition triggers reversed. If you don't want to meddle with the harness wiring, you can just swap the spark plug leads around at the coils. Pull off the leads for the 1 & 4 plugs and put them on the coil terminals where the 2 & 3 leads are currently. Likewise, move the 2 & 3 leads to the terminals on the coil where the 1 & 4 leads are now. Then try cranking again.

If that doesn't do it, then something is wrong at a deeper level than just software. The MS clearly believes that it's doing the right thing. It's commanding fuel and ignition events to occur, and apparently they're not happening. Could be wiring, could be hardware inside the MS, could be something wrong with the car. But I'm pretty confidant that it's not software.

Actually, this may be something blindingly simple like your fuel pump not running. Before you swap the plug wires around, try forcing the fuel pump on by putting a jumper wire between "F/P" and "GND" inside the diagnostic connector which is under the hood on (or near) the drivers' side shock tower, as per this illustration. You should be able to hear fuel running through the rail when the pump is on.



Oh, and the link you gave me (http://boostedmiata.com/MS/msq/firmw...extra.ini.hr10) isn't an MSQ, it takes me to a copy of your msns-extra.ini file.

Tried reversing the wires, nada. Also tried the fuel pump thing and you could hear it turning on.

Hi guys -

I don't know if this is any use at all, but I've been having a problem with TunerStudio that *might* be related. Basically, whenever I burn *any* new MSQ to my MSPnP using TunerStudio, starting gets totally hosed - the car just cranks, doesn't start. However if I load the MSQ in MegaTune and burn it to MS that way, startup works just fine.

Dunno whether we've got the same problem here, but ... have you tried burning the MSQ using MegaTune instead of TunerStudio?

DJD, check to be sure TunerStudio is set for the correct firmware version. It sounds like yours may be configured for a different code.

@Turbo 4
I think I'm having the same problem as you. Can you post your results if you figure everything out? I'll post what I got.
