Hello,
I have Ktuner v1.1 on my Civic 2018 Hachback (CVT) and i installed the tune that came with the device itself - 21PSI boost map.
it is possible to get at least 40HP from changing parameters on the ktuner program? it feels that i can squeeze more power from the crank.

Thank you!!

You can certainly achieve more power than the included base maps with additional tuning of ignition, fuel, and turbo characteristics. If you're not familiar with the process there are classes online where you can learn.

Thank you, this question was also relevant to me.

@KTuner

I have been using KTuner V2 from quite a while now.
I was using Stage-2 map on stock 1.5T cvt

But since I got PRL CAI and Race MAF
I can't use stage map any more.

I ordered TSP, but my ecu goes open loop on WOT so the AFRs are too rich, they are around 9 to 9.5

Which is forcing me to custom tune using start 21 as a base map.
And PRL race maf scale as a base scale.

I have rescalled the maf. But I am not getting the same power as TSP.

Please tell me from which table I can advance the timing to ignite the fuel that goes unburnt and causes rich AFRs

If you aren't reaching AFR targets you'd actually want to tune the MAF curve. If you rescaled that properly your AFR should be right on. Adjusting any ignition values would be on you.
