Hondata

Hello. I recently replaced my starter and in the process I decided to upgrade my fuel injectors from stock to RDX 410cc. In the process I replaced the knock sensor. I swear I didn't touch it, I looked at it and it fell apart. Anyways after getting it put back together I installed the base RDX 410cc calibration. Startup was great and everything sounded good. Once it got up to operating temperature it started surging from anywhere between 0900-1600rpm. Respectfully request one of the hondata gurus take a peak at my attached datalog. I didn't notice any DTC/errors, but I didn't let it run long either.

The only mods are the 410cc Acura RDX injectors.
Thank you for looking.

Attaching the calibration file on it.

Well this is embarrassing, but I'm gonna post my ignorance with hope it will help someone else in the future. When I replaced the starter I installed new intake manifold and throttle body gaskets. Well, guess what happens when you install the throttle body gasket upside down? @_@

Got that fixed up and she runs way better now. No surge. I would still like to get an expert eye on the data in the near future but wanted to own up to my mistake here before anyone put any thought into it.

Good catch. My first instinct was to tell you to check for a vacuum leak. Post your datalogs when you need help.

Good morning. I captured a datalog to include two 3rd gear pulls. I'm guessing the knock count and percentage registered is not ideal, but I'm not sure what I am looking at. Respectfully request review. Can that be dialed down a bit? Thank you.

The car is running lean. Adjust the fuel and reduce timing where knock is present.
