ok found the leak. its been the blow off valve. also got p0244 again with cel.

if you look at the manifold relative pressure in log2 you'll see there's a drop off around 5200rpm - I'd wager your boost solenoid is on the blink and that's why your getting the code as well.

Your learning view is still showing big positive in the first column, did you reset the ECU after you fixed the leak?

here's an updated rom with some timing pulled for tidyness as your knock correction is pulling a little bit on you.

yes, first fixed the leak then reset the ecu. and i also noticed this drop off. felt like a fuelcut. cel flashed at this moment as well.

checked the solenoid by using the test mode. works like it should

if this is the post reset learning view then you still have a problem - look at those A and C values, very high. If it's high then you could also be leaning out on boost which would be dangerous for you.

Check again for leaks, check everywhere and everything - the car thinks it needs to add fuel so there must be a reason for it. I'd stay out of serious boost until those values settle down a bit or you find the cause.

ok. ill check again for air leaks and other. Also replace the front o2 sensor.

i do also think that the oem solenoid is not working well. Does it makes sense to replace it with an aftermarket 3port solenoid? (kits by perrin or cobb are available with harness for p&p and using with oem ecu)

thanks

yeah 3 port is no bother, you can get the classic WRX 3 ports for cheap money on ebay or the MAC style valves too can be had for not much cash.

now got a new o2 sensor

Also threw out oem solenoid and switched to 3 port. got one by mac.

works well so far. got boost up to 17 psi but to smooth yet.

here are two logs again.

try setting your initial wastegate duty to 50 from 3600rpm upwards and set the max to 80 all the way up - looks like your hitting the max values just.

Timing looks happy enough though and the peak MAF figure isn't too bad either so just work on the midrange a bit for now until you get a nice smooth engine load.

Like this?

yeh something like that - try this one out.

still the same. Boost goes up, then falls back to 7,25psi and go slowly up to 17 psi. increased wastegate duty, but didnt helped.

edit:
did a few runs and drive arround. IAM is at 16 again. Now the "hole" seems to get smaller.

here - try this one, have added a little fuel into the maf scale as well - once you got past 220 g/s the AFR seemed to dip a little. I've defaulted the IAM to 16 as well so that should save you some time.

thank you sir, works very well so far.

I know that has no business here, but since yesterday i got p0245+p0246

My new 3port solenoid isnt working. the solenoid itself works. wires are all well. But the ecu just doesnt switch.

In testmode with green plugs, no reaction from the solenoid.

on a newage car there is no reaction from the solenoid in test mode - you'll get those codes if you try and use more duty than the maximum value though. Normally the max is 90 so if your trying to get 95/100% from it you'll get a code. Some roms have the max value defined and you can increase it - or just nuke the codes.

ok. deleted the codes but it came back.

doesnt increased anything on your last map.

Also got a software "free ssm" which where i can check several components on click. also the solenoid. But even that isnt possible.
