Just hoping someone or anyone can help me figure out what to do to get my car running right again
So i recently bought and received a hondata flashpro with intentions of building my car into something more than what it is. The car is an 2013 Civic Si Coupe which is completely stock (2.4LDOHC V-tec K24z7). After a bit of reading and videos I went and put a basemap on the car only to find out a few weeks later the car would start running like complete crap. Feels like the car is bogging or feels very similar to a cylinder misfire. A few days ago I figured my best option would be to just tune the car back to factory with the factory basemap. I was able to due a quick datalog on my drive home from work this morning and will post it on this message. Any ideas, pointers, advice, or knowledge of what this datalog may be showing would be greatly appreciated

Exactly what base-map did you load? Since your car is bone stock, you don't want to load anything that's meant for mods, like intakes, exhausts etc. Those calibrations will not run right on a bone stock car.So i recently bought and received a hondata flashpro with intentions of building my car into something more than what it is.

When my car was stock I simply loaded the stock equivalent calibration on the FlashPro manager and then made adjustments to that one, like removing the rev hang, changing the rev limiter and basic stuff like that. Once I made my adjustments, I saved it and then loaded it to the car (ECU). Car ran great!
At first I did the stock MAF tune. Was too stupid to realize it was not the reflash I wanted to do. As soon as the car started to run weird I just switched it back to factory.
and it's still running like crap despite returning it to stock?
Yeah. I watched the datalog from start to finish and looking closely it only feels rough at around 4-5k rpm. Also the A/F sensor goes up to 29.4 or so and stops then goes back down to around 14-15?and it's still running like crap despite returning it to stock?
Okay, Exactly did you return it to stock?
I had to return mine to stock last month and I had no issues.

Yeah. Stock factory basemap and didn't touch the calibration at all. Do you think I should try to upload the stock factory baseman again?Okay, Exactly did you return it to stock?

I didn't do it that way. I will go and try that right now and update you after I take a little drive.
So I definitely noticed a major difference feeling wise but getting on the throttle to get onto the interstate I still got a little bog. Other than that 1 time I really didn't get on the pedal or feel a bog at all. Maybe it takes a little for the ecu to fully get back but if I drive the next few days and it continues I may have to replace my spark plugs next?Yeah, try that!
Yeah I would drive it a bit before doing anything else to it. But it wouldn’t hurt just to take a look at your spark plugs and see if they need to be replaced.
What were the knock counts during your datalogs.
also the ecu does not take any time to make changes with your bog that you felt.

Had a total of 6 knock counts and they were divided among knock 2, 3, and 4What were the knock counts during your datalogs.

17 minutes I believe. About a 10 mile drive.How long of a datalog
I know this is probably not what you planned but you can reach out to a professional tuner and get the car running slightly better than stock. It will cost you some more money but it would also be a reliable route. Once you get onboard with a tuner, whenever you add modifications to your car, they would charge a lesser additional fee to update your current tune. @Allmotor would tell you some great tuners in the scene.
