Updated Firmware, now engine wont fire
5 Attachment(s)
I am in desperate need of help. I was having a ton of issues with megasquirt and I thought updating the firmware may help. Well after the update finished and I loaded the previous tune I had, the engine wouldnt fire. Is there a setting that doesnt come a long with a tune that I need to update? I am clueless and pretty screwed right now.
Is there a chance I fried my coils updating the firmware? I also had the following issues loading the map https://www.miataturbo.net/attachmen...ine=1433109296 |

Here is a data log of the car trying to start

What version of megasquirt. Post a log and tune. Did you unplug your coils when flashing, and if not why not.

Data log is in the 2nd post |
What version of megasquirt. Some versions dont burn up coils when flashed. Also my advice is to leave it alone for the day. No need to get mad at it, only makes it harder to fix.

But you might have remembered to unplug the coils if you were relaxed. If you have to set the coil output to inverted then its possible they fried. Someone else who has used ms2 will probably chime in.

All this talk of possibly frying coils, but that's so easy to check, I'd start there.
No fuel or rpm signal on the log you posted though, no idea where to go from there. |

Pull the spark plugs, make sure the plug has a ground to the block, and check to see if you can see spark while the engine is cranking.
You probably won't see it though, and the coil pack might not necessarily be bad. With no RPM signal it has no idea when to spark. |

I actually have new spark plugs sitting on my work bench. would it be an issue if i just pulled 1 wire, attached it to a new spark plug, grounded it and checked?
