Trouble Codes

Well, I recently got a CEL again. I assumed it was for a bad cat again cause changing the maps on the AP deletes all the learned data.

It was the cat code again, but there were two other new ones the AP picked up. First was P0234, 'engine overboost', which I didn't pay much attention to.

Then the second was under a different section on the AP screen titled 'IC' and the code was U2064. It didn't give a description. Does anyone know what this code means? I tried searching on M3F but apparently they are changing servers right now and the site won't work. Do either of these new codes mean something is hurting my engine? I was getting wild fuel cuts on my way to Quebec cause it was very cold, does the second code have something to do with that?

But yea, I'm not paying much attention to the overboost code cause the new tune on the AP spikes around 22-22.5psi and holds 18-18.5psi.

When I was using Stage2+SF 93 v103l I wasn't getting any fuel cut around 0 degrees, but before I left for Quebec I put Stage2+SF 91 v103c and was getting fuel cut because it was -15 to -20 the whole way.

Has the AP given you any trouble codes before? Maybe you running the wrong map for your set up for the cold weather conditions. I hear cold weather temps could cause fuel/boost cut but never a CEL?

No U-codes listed in the shop manual. Sounds like it's an AccessPort-specific code.

Thanks for the link.

And the AP doesn't GIVE me trouble codes, it reads them. I removed all the codes from the ECU, so I hope they don't return. I do have the right map running right now, I checked and double checked.
