Hi,

I installed a new +09 Acura TL 79mm TB w/ P2R parts on my DBW S2000 w/ Flashpro. All the installation went smooth and the car runs OK, even went to the dyno. But after a couple of days of daily driving, the CEL(P1129 "MAP sensor signal higher than expected") comes up. After the CEL comes up, the car goes into safe mode and have to clear DTC with the Flashpro.I tried using the OEM map sensor connection from the S2000 IM, and the map sensor located on TL TB as well and got the same results. Yesterday, i changed back to the OEM S2000 TB and haven't experienced the issue.

The owners over 8thcivic Forums have been using this Acura TL, TSX and other TB's, and haven't got this specific CEL. There's a DIY that they posted over there to calibrate these "non standard" Honda TB's and get rid of other CEL's. But I haven't tried this procedure.

Any help, recommendations or past experiences before I sell this?

Thanks!
