Also, when I am doing a new calibration, it gives 8 options; the 2nd option is 240 lb-ft tune and the 3rd option is CARB pending 240 lb-ft tune. I have tried both, but I was wondering if they are the same or if I am supposed to be picking one in particular.

I disabled traction control, tuned it, and took it for a spin. 2nd gear felt better...it pulled and felt smooth. It bogged a little in 3rd. I read that disabling traction control by just pushing the button doesn't fully disable it, so I tried the method where you push the button off and on while ...

I haven't tried that. Did you see something that indicates that might be the problem?

Ok, I think I did this right. I uploaded a new calibration and was able to replicate the problem. On the first datalog, it bogged right after shifting to 3rd gear. On the second datalog, it was right after shifting into 2nd.

With your FlashPro connected to your computer (the FlashPro can be, but doesn't need to be connected to the vehicle for this), from the FlashPro Manager software, click the "FlashPro" button in the toolbar. This should pop up the "FlashPro" window. On the Flashpro window, click the "Calibrations ...

Sorry, I'm new to the world of tuning and trying to figure it out

Then I'm missing something, because I thought you just select 240 or 250 and that's it. I didn't know there was anything else

I hope I did this right. I attached the datalog. The calibration was the CARB 240.

Saw from the datalog that air:fuel was hitting 29:1. Returned the car to stock with PRL intake and it's running fine. Not sure where to go from here.

So I datalogged today and was able to duplicate the problem. I've got the datalog graphed on my computer but I have no idea what I'm looking for

I'm not exactly sure how to do that, but I'll do some research and figure it out.

I recently installed the PRL HVI and Hondata CARB on my '22 Si. Initially everything felt great. In the last couple weeks, under heavy acceleration (not full throttle), it feels like I'm hitting a rev limiter between 5,000 and 5,500 RPMs. I usually drive in sport mode, so today I thought I was see ...
