Hey guys!
Recently just purchased the Ultimate Racing 3" header exhaust. The car still sits stock, stock catback, only modifications done is my exhaust, alongside some other cosmetic mod like my Ktuned coils. I was curious if running the hondata reflash would benefit me in any way temporarily? I obviously want to get a tune, but purchasing the dp, hondata it's been a costly two weeks to say haha, just want to enjoy some gains and any advice would be greatly appreciated. Thanks!

You can try it and check to make sure the AF is safe and there is no knock.

sorry little unfamiliar with the terminology but what do you mean by AF? I'm assuming airflow? Which parameters should i monitor during my drives to determine if the AF is safe. Thanks.

i've attached a short log, did two 2nd gear WOT pulls, short daily driving. Oddly enough not sure if i'm reading it wrong but i noticed knocks on downshifts. this drive i did prior i only had 1 knock but the drive back i saw it logged 4 knocks. Hoping this short long can maybe provide some insight into the flash. *FYI running stock reflash* currently ... ultimate racing dp. Thanks!

here is also the calibration file !

AF is air/fuel ratio.

Hey, just posting an additional logger datalog, includes daily driving in stop and go traffic. Some WOT pulls. 9 Knocks record, some were odd to be as they begun right as i was taking off, downshifting and some expected during WOT. I have the tune also posted in earlier posts.
Thanks!

The car has a decent number of timing retard and some knock. I suggest you reduce the timing. The MAF may need a minor adjustment down low. Overall the MAF is not too bad.
