RomRaider

I am currently tuning my 06 sti via ecu flash. When I try to do a wot pull from low rpm I hit boost cut and get a P0244 code. On my data log boost is pretty spot on from what I can tell. Is there something I'm missing? Anyone ever come across this problem? attached is a data log.

firstly check you have fast polling enabled and also log your target boost. by the looks of your turbo dynamics you're a little over target - when you log the target you'll get a better idea of that. Also check your rom for the fuel cut/boost limit tables as your fuel cut limit might be lower than your target boost.

Check your boost limits tables.

I forgot to add that my boost limit fuel cut is set to 22 psi. I'm not familiar with fast poling. What is it and how do I enable it? I forgot to check target boost in this log, but last time I was monitoring, it was within .1 to .2 psi.

fast polling is an option in romraider logger, look on the menu make sure its got a tick beside it. Once you have a good log and the rom posted up it will be easier to see what's going on.

Here a new log. Fast polling was already enabled, and boost target is on there.

OK so if you look at that log at 2500rpm your target is 0.98bar of boost but your manifold pressure is 1.2bar so you're already overboosting based off your targets. Are you able to share the rom to see what else is going on with it?

I've attached a plot from your log - blue is target, red is manifold pressure, green is your A/F Sensor #1 because you dont have your wideband logged:

It wont let me upload the rom. I've been super busy lately. I'll try to get some more logs this weekend.
