Fuel trims zero?
Ok, so I saw in this thread that there is an issue with logging fuel trims. I'm having this problem and can't figure out why. I'm running the 88590715 ROM (US IX) and since switching it to Tephra v7 I can't log fuel trims. I've tried the obvious - re-install the rom, re-download the rom.. Nothing is working. If I load my stock tweaked rom fuel trims log just fine.
Anyone have any ideas??

There is a thread in the CT9A section about the same thing. If you download a Phenem ROM I would stop there and start with a real Tephra ROM. If you disabled the rear O2 or did something else with O2/trims That is your next target.
Have you played with the "Closed Loop Long Term Fuel control" or something to that effect? If it has been dropped below a certain Hz range to keep the LTFT from being applied in boost it could affect cruise if it was high enough. Between periphery and bad sensors that should be the only 2 other causes.
