No Spark after firmware update
 

Hey, friends.

I was trying to take advantage of the newer firmware options, and I failed to read the instructions, "Important note when performing firmware flashes/upgrades." I didn't disconnect my coils/ignitors before upgrading the firmware. Also, I got several errors after the update.

I've gone through all of the troubleshooting steps per the FSM (section G-19) and replaced my ignitor but no dice. I don't see a spark from the sparkplug cable to the chassis ground, and the fuel pump cycles every few minutes.

I've attached my PreFirmware and CurrentTune MSQ files.

Sorry for being a tard, and any help is appreciated.

Am I just able to load my old tune prior to the firmware update and that will downgrade everything?

If the pumps cycles every now and then, you have a settings error. Did you connect to the ECU with TS after upgrading or did you reflash the firmware and hoped it would be ok?

Of course, good sir. I am happy to Zelle someone for their time. A few updates:

1. I reverted to my old firmware (3.4.2) and known good tune.
2. The lack of spark seems to be coming from no ignition signal.
3. I've replaced the CAS and tested the voltage to the connector.
4. While running the highspeed logger (composite logger), there is no Engine Speed (RPM), and I'm too stupid to understand the Lost Sync Counter and Lost Sync Reason
5. I've attached the:
   1. Tune
   2. Composite Logger
   3. A screenshot of the Ignition Options.

Thanks everyone. I was able to work with my tuner and get it fixed. I also had a bad CAS.
