To give a quick rundown:
He is on Instagram as @willitboost. Seems he has had his Pulsar running on it for a while! I've DM'd him yesterday, awaiting a response. There's a video on how he reflashed the ECU on YouTube:

https://github.com/WillItBoost/M744-Stand-Alone-ECU with the last update around three months ago. But no source code yet, which is what I'm very anxious to see (and fiddle around with!)
I found that this guy does some cool stuff for a living and seems respected in that community. I think some of you underestimated his abilities, as did I tbh, as I've not got much knowledge on OEM ECU's, but fair enough this guy got it working. I wanna run my dream build on this...
