2.0L CivicX 2.0L Tuning - BIG Gains Confirmed For The Second Time

[bcrichster]

I'll try to do this again tonight and maybe use a different wire as well, but it was not flashing when I connected it earlier (if I remember correctly). But it does seem to have all the information including VIN and ECU number and the the flash history as well.

Make sure the PC has finished all Windows updates, "Secure Boot" is properly enabled, etc..

Just updated my laptop. I'll have to try tomorrow because it's 30C (86F) temp outside right now so the heat is just extra frustrating

That’s it?? Try 110° heat index in NC

Anyone use etunez for your custom tunes?

I can't stand the heat at all tbh. I was sweating profusely within 30 seconds of getting in my car...

So I'll be trying to flash it again today and see how it goes. Just to confirm, the car needs to be in ACCESSORY mode not ON mode right?

Key fully on, engine off.

This might have been the issue yesterday, I was in accessory mode.

So finally got around to flashing the new tune. Looks accessory mode was the issue, everything worked well when I tried it with the key in the "On" position.

As for the lowered VTEC, you can absolutely feel the difference. Basically the same as everyone has said, it's less aggressive, but you can feel that smooth transition and obviously much easier to hit VTEC now. Now if only we could lower it to say 4500 RPM

Thank you to the guys at Ktuner btw for all the great work!

Installed the K&N short ram and not my trims are showing lean. STFT when accelerating goes to 25% and LTFT steadily increasing over time, now sits at 11%. Normal? Will it adjust itself? I checked and all connections are tight. Thanks for any input

That means they likely include a MAF housing that's not close to factory. You'll want a custom tune to correct that.

Thanks! That was my next step. Nice to catch it in real time with the V2 unit.

I didn’t choose a throttle response option, can I just plug the ktuner into my car and select one and reflash it just like that?

 

[KTuner]

Yes

Looking to get this for my new 2020 civic sport but how much will it help throttle response from a stop? It just doesn’t launch as hard as my old 17 civic with the 1.5t. That’s my main reason for tuning is if it will get better throttle response I’m all in
