Speedometer Recalibration?
Does KTuner allow for speedometer recalibration on this platform? If so, where is that option located?

Re: LAM or LAM.ADJ for 2007 S2000
I have since added a stand-alone NTK AFM to the car, and I can say with certainty that anyone tuning with the stock sensor should be tuning to LAM.ADJ, not LAM. The standalone meter is dead on the adjusted value, so using unadjusted will end up being much leaner than intended.

Re: Tuning for E85 using the stock O2 sensor?
I understand the difference between Lambda and AFR, but the logs that come out of KTuner (at least the version of the software that I was using last year) show AFR, not Lambda, even though the columns in question are LAM, LAM.ADJ, and LAM.CMD. The values in these columns in the datalogs are typical ...

Tuning for E85 using the stock O2 sensor?
Hello, When I was tuning my supercharged 2007 S2000 on 93 octane over the last few years, it became evident that the stock O2 sensor pegs rich at 10.14 LAM or 11.52 LAM.ADJ; no matter how rich the car runs, that is the indication. That worked fine for gasoline, as I was generally targeting 11.8 LAM....

Re: Inconsistent AFR?
I was under the impression that WOT fueling was open loop and not affected by LTFT. Am I mistaken?

Inconsistent AFR?
I have been trying to finalize the tune on my supercharged 2007 S2000, but AFR seems to be changing without any changes to the tune. I went out and did 5 back-to-back 3rd gear WOT pulls on the same stretch of road without so much as turning off the engine, let alone changing the tune. Here is a comp...

Re: ECU pulling timing above 1750 mBar?
Then you can always leave it out for safety. Again, the ECU does many things in the background. Ok, I understand that too, BUT the ECU or your program is doing something that I don't want to do, and there is no apparent cause. I find it difficult to believe Honda built in an automatic reduction of ...

Re: ECU pulling timing above 1750 mBar?
Clear timing drop right at 1925 mBar. It is exactly one degree below commanded. Below is a screenshot of the discontinuity.

Re: ECU pulling timing above 1750 mBar?
I absolutely can do that, but as I mentioned, my fear is that this missing degree of timing will come back in at some point because I do not understand why it is being pulled. I have been through the program and the maps numerous times, and I can find no other setting that should be affecting my tim...

Re: ECU pulling timing above 1750 mBar?
Setting the Knock Limit table high (60 degrees) seemed to help in the 1875mBar range, but it still drops a degree around 1900 mBar and up. I tried everything; KL tables set high with KR set to 0, both set high, I removed my IAT compensation (even though temps were too low to trigger it), and in ever...
