Vehicle: 2017 Civic EX-T coupe

Total tuned time: 24(ish) months

Total tuned mileage: 25,000+ miles

Tuning device(s) used: KTuner V2

Tunes used: custom tune from Brent @PFI speed (260whp 340lbft)

Fuel used: Full pump E85

Additional engine mods: Redline 360 catless downpipe, no name intake, PRL flex fuel sensor, full 2.5 inch custom exhaust, hasport lower mount, clutch master's fx350 and single mass flywheel

Problems/issues: Blue smoke from turbo seals (i.e. turbo overspin and caused failure to oil seals)

Driving style: Hard mostly, in power as much as I could be.

Tuning experience notes: Went very well considering the car made 340Lb-ft and 260hp to the wheels. Only issue was turbo seals. Had a blast with the car, ended up selling to fund a 2019 civic Type R that I will be tuning using hondata in the near future.

@6000ft elevation

Cheers

Mileage: 12,000 miles

Tuning device(s) used: KTuner v1.2

Tunes used: Dual calibration, see photo

Fuel used: 91-94 octane

Additional engine mods: none

Problems/issues: A weird smell after heavy acceleration, and sometimes transmission jerk\surg. I am getting ready to flash back to stock because I think it is having bad affect on CVT.

Tune experience: Little experience, read gtman's thread on recommendations.

Not sure what that "weird smell" could be other than some funky rotten egg WOT smell which is normal really. With your basically conservative setup, your CVT should be just fine.

Have you upgraded to version 1.0.9.5 of the KTuner software? If not, upgrade the KTuner software and then re-upload the tune. This helped others with similar "jerking/surging".

The smell is almost like burning coal. The first time it happened I thought it was the outside air. But then I realized it is always after hard acceleration. It tends to linger for about 5 minutes. Yesterday, I was on the freeway and hit WOT to pass about 4 cars before exiting, I hit about 85, then exited. I then smelled it and made a 15 minute stop at the hardware store. When I restarted the car and was backing out I smelled it again, and the car felt like the brakes were on as I was backing out. It felt fine when I put it in drive.

Does the attached photo show what a typical Ignition Base map is supposed to look like?

Not normal as in all the time but you can get that sulphur smell at WOT from the cat on occasion. Bad gas maybe?

Or I could be wrong. :cool:

Update with a fresh dyno after a lot of street WOT logging and fine tuning … not bad for a stock turbo …

Nice work. So this is your 24 psi self-tune?

Am I reading that right? 223 hp and around 265 lb/ft of tq? That torque curve looks fantastic.

Is this just with parameters change in ktuner starter 21map?

Nice work. So this is your own, self-tune?

Yes, it's my own tune after a lot of logging and experimenting.

It's a dyno plot and numbers may vary from dyno to dyno, but compared to my first tune my curves are a lot flatter, I have a little less torque pre 3500 now and a much beefier top-end. My first tune had a 211whp spike at 5400 to fade down to 190whp by 6400 rpm (typical for a tune based on the 21 starter). I have tried countless boost target maps to try and figure a steady torque / power band. The tune can be further refined but there is not much point in going after the last 2-3whp :)

Is this just with parameters change in ktuner starter 21map?
No, it is a complete custom boost target map, with tuned MAF scale and custom ignition tables
