Exclamation Car cranks but won't start after openflash custom tune install

After installing a base map for a supercharger using open flash. My brz cranked but wouldn't start and threw code P0335. I changed the sensor with a new one and it still didn't fix the problem. When I reverted back to stock the car won't even crank.

Any ideas?

Any ideas?

After checking battery is good and termials clean and tight see below



My guess would be


Port injectors installed do not match whats scaled in tune
MAP manifold pressire sensor installed doesnt not match whats scaled in tune


The Direct Injection computer the one on side of engine doesnt npt have all tgree mount bolts in and tight, thats its earth, not earth on that module weird stuff happens


Or you have been given an incompatable rom ie manual rom in auto car or pre facelift rom in post facelift car or other way round. That will cause security to trip amd car wont crank.
