Previous owner running Hondata

Alright so I recently purchased a stock 9th gen Sedan, and after having it for a couple of months I kinda figured out that the person who had it before me was running hondata. I believe he tweaked the Rpm that Vtec kicks in at, and I just want to know, what is the oem Rpm that the vtec should kick in at?

12-13 its 5200 rpm and 14-15 its 5000 rpm.

you may be right. keep in mind OP theres 2 engagement windows for vtec the lower and upper.

Si or non Si ?
Basic check to see if the car is flashed and currently running any hondata map. With cruise control off press the set button and see if it displays your current a/f

Ok thank you guys, and yes it’s an Si. As well when I push my deceleration button with cruise Control off, it does give me a reading, found that out the other day on accident actually. What do you mean by upper and lower engagement points for vtec?
Because when I am doing a pull, I feel like the most power I get is pretty high up in the Rpms, so I’m think for some reason he pushed the vtec point pretty high.

If pressing that button gives you an AFR reading on the tach then it's 100% a reflash. A factory ECU calibration doesn't include this, it's a feature specific to Hondata calibrations.
