I'm running a 2001 Honda s2000. Nothing has changed on my vehicle in the past 8 months.

@Hondata: Did you get a chance to test the AFCMD scenario on a PRC ECU?

How about the TPS scaling issue? Some others have the same issue. (I know it is strange, as I expect that part of software would change).

Thanks.

The PRC ECU runs exactly the same code as the PRB.

Try this with the TPS, reset the scaling and then see what the TPS minimum is. If it is below 0, then manually -1, -2, etc and upload until you get the TPS to read 0%. If you get below -5% then your TPS is too far out to compensate, and needs adjustment.

The AFCMD normally jumps around all over the place - you would have to ask Honda why. Going to around 12.5 is normal under high load, but it also will go rich briefly after overrun cutoff and when leaving idle.

Hondata: Could you upload a datalog (1.5.1.0) for me to compare please?

A few minutes of road driving is good enough (after car has warmed up). I really want to know if my KPro is behaving the right way.

Thanks.

Sample datalog from a cold start.

Thanks Hondata.

Would you have a sample datalog from v1.5.1.0? (The one above is from v1.3.1.0).

In version 1.4.1 my TPS was 0% In ver. 1.5.1 my TPS is already -1% I try to calibrate it to reach 0%, but TPS returns to -1% It's normally?

Yes I noticed this. And this is still problem for me.

If your TPS is reading negative, then you need to decrease the minimum %.

The AFCMD looks normal. If goes rich at higher rpm for catalyst protection.
