ms3 pnp pro possibly bricked
i just installed the megasquirt3 in my 02 Miata. I was trying to mess with setting when I kept getting disconnected. then lost connection completely. I noticed the serial to usb C connector was bent which probably was causing my disconnects. I got a new usb to serial connector but for some reason I still cant connect. I tried to re flash firmware but it cant connect at all. it shows the port and the device but doesn't recognize the megasquirt or firmware I believe all the disconnects caused it to be corrupted. is there a way to use a jumper like on the ms2? if so where exactly is the jumper located on the board. would really appreciate any help.

i was able to get the new firmware installed using the Jumper. i disconnected the coils as they say to. but once i loaded back my tune i have no start, huge backfires... sometimes it almost starts but sounds like only 2 cylinders are firing. i double checked spark and was not able to see any spark on plug #1. put brand new coils still the same... maybe dealing with possible low voltage or a short because i was not able to get the timing light yo work at all. ill need to pickup a electrical tester to check. any one have any ideas what this might be caused by?

update looks like my brand new spark plugs were not gapped correctly or bad. Ive attached my current tune. car seems to be running pretty well start up is a little jumpy and i stall occasionally on deceleration. but im super happy i finally got her running. i was worried i was gonna need a new ECU.

I ran the FF640's for a year and did not need to adjust trim tables. I only needed to change deadtimes and Req Fuel to help scale my fuel tables. Just go with their guide: https://goflowforce.com/instructions
