Saturday I lost the main ground to the t-stat housing ran like junk fixed ground and it went lean on afm.
Plugging into ecu/s300 it had/has a tune that I’ve never seen before things that were different are fuel tables most parameters including vtec points along with over heating protection rpm.
Does this seem possible? I feel like I’m losing my mind.
Thank you in advance

What is the serial number that is on the s300 board inside the ECU?

2.8.2.0 build 3207
s300 serial number 61274 bought from HA motorsports last July.
When I last found this problem, I reloaded the original tune for the car and they raced the following weekend and same issue again.
odd looking data logs and a missing/reverted tune from both times and the original tune.
I'll include both tunes and the odd data log.
