Hondata

I have a kpro v4 that was installed into a pnf ecu that's in a 03 civic si using the matching harness. When using the k20a3 map in now throwing the p1166 o2 sensor heater code. But when swapping to the matching accord k24a4 map the gauge cluster coolant temp gauge does not work and I still get the same o2 sensor code. Prior to the kpro install I had no codes.

without the calibrations being posted it is impossible to say what it could be.

It's the factory k20a3 and the accord k24a4 calibrations supplied from Hondata using the latest updates for kpro and k manager

You need to post the actual calibrations you have uploaded so we can see exactly what you are using.

ok i replaced the o2 sensor again with another new one. the codes are now gone but i still have the same issue with the accord a4 map. also my laptop is new and is running windows 10 (headache already). i plugged my kpro in and opened kmanager and said i needed to update kmanager. so i did to the newest version. upon completion i reopened kmanager and it stated i needed to update the kpro v4 firmware. after the update my kpro quit responding to my computer, bluetooth no longer shows up on my phone and my idle is either surging from 1k-2k or at a constant 2.5k. here is the accord map that i had tried.

What is the serial number that is on the K-Pro board inside the ECU?

From Help, About, what is the version of software you are using?
