I can't comment on the map, but suggest you go back to the fundamentals, as the full setup you're running may still be beyond the limitations of the fuel you're using.

On that, if you could give a full run-down on your setup, it would be a big help to those who are experienced with the engine and software/ECU you're using.

It may be something as simple as the sparkplug heat range still being too hot and causing pre-ignition.

Does it have valve reliefs on the pistons? Have read a couple of times where people needed to break the edges to remove hot spots.

Yes sorry probably should’ve explained a bit more

so it’s a 180 SX with an L98 running the standard e38 ECU using HP turners

basically factory motor with upgraded trunnion kit, oil pump, 1 7/8 headers into a 2 1/2 inch exhaust

it does seem to have some kind of small cam in it bigger than standard but unsure of the size

Will link my most recent attempt and a log file as well
