52350016 is a JDM RS ROM ..

So you have no boost cut or boost limit ..

better make sure your definition is correct before you change ..

I have raise the offset to 300 and still hits the code. Wonder if I should max it out and try again...

BDEL is only part of the equation for P1235

This is one of the reasons why I mentioned its not good to use either EBC or MBC on this car .. most of those using the stock boost solenoids are running the same boost as those on EBC ..

How much boost are you running ??

We'll walk thru this step by step..

Then it's not boost target related.

Look to the airflow target tables next.

When does it trip the code? low rpm WOT?, low rpm part throttle?, etc etc?

I am running 1.3bar and 1.7 bar respectively. Usually the checklight comes on at ard 3000 - 5000 rpm at 80% throttle.

When cruising 5th gear 3000rpm and increasing the throttle to 80% it will throw a limp mode at abt 5000 - 6000rpm..

I noticed Airflow check has 4 tables of which table #4 is different from the rest. I tried increasing the airflow tables 40% and it immediately when into Limp Mode. So i guess the more isnt better..

I am looking at more stable performance when I increase the airflow check to 30% but it will still throw the code but at a later rpm. Can the Airflow #4 be edited?

I actually adjusted the Passive WG duty cycle and it seems to help in the problem. I no longer gets the error but i havent tried part throttle acceleration yet. Will see how it goes..

Code 0122,1233

I got a new code P0122 and P1233. This happens only at low speed and low rpm. The car throws a check light and acceleration is very very slow. Itz definitely not running on low octane map and I am not sure wat causes it.
