Hi , evolutionm members :

I just installed AMS boost pill and flashed ECU with stage 0 (base) map provided by AMS.
Now I am having these two codes : P0068 and U0167. Here's the story...

-----Right after reflashing my map, I went to for a test drive. Car performed pretty good at about less than 20% of throttle. I did realize that there was a significant power gain.

-----Then I did my first pull, the CEL flashed and stayed on.

-----I pulled over and restarted my car, it was still there. Turned off the ignition and read the code with AP and It shows P0068. I erased it and reflashed it with AMS base map, restarted my car, the CEL came off.

-----Then I went back on highway did my second pull(4th gear). CEL still flashed when high boost kicks in.

-----Pulled over again did the same thing, turn off the ignition and read the code with AP, it showed U0167. Erased it and restarted my car.

----- Third pull(3rd gear), CEL flashed again,

-----pulled over agian and read the code with AP, no code.


I know I should contact the AMS, but right now is out of their operational hours. I have to wait till tomorrow. right now , I am so worried about my car,,,,

help please.. !

 

Any update?

Maybe give a second look at the boost pill and; boost pill may have moved shifted, hose may have come loose, maybe there is a small leak in the rubber of the hose if the rubber was more dry when you take out and put in the new pill. Had that last one happened to me, cost me a trip to the dealer and a 300$ bill to find that out.

 

Put it back to stock and do some pulls. If it comes back with the cell go to dealership

Stop driving it and check that solenoid. I believe that code indicates a boost spike

 

I think p0068 has to do with maf sensor readings so there may be a vacuum leak or the maf tables weren't adjusted properly?

U codes are communication codes
