Does this mean any driving without a speed sensor is not recommended and will cause engine damage? Or it is ok to drive with lower rpm? Let's say <4000rpm. Thanks!

The speed sensor inside the transmission is not working. How would K-pro behave without the speed sensor input? The CEL is on due to the speed sensor failure and I saw the idle rpm up-and-down from ~800 to 600rpm. Is it still safe to drive the car without causing any engine damage before the speed ...

Does OBDII scanning also check sensors' malfunctions? But I am not sure which sensors it checks. If it is disabled, how can we tell if all the sensors are functioning poperly? What happen if one of the sensors malfunction with no CEL due to the ODBII disabling? Would this hurt the engine if we keep ...

Is it better to use a defouler and leave the OBDII on? What is the catch of disabling the OBDII? Thanks!

I will be installing a racing header and I heard KPro could disable the O2 sensor to remove the CEL. Do I just check the "Disbale P0134 (O2 sensor response)" box to eliminate the CEL? Will I still need a defouler with the KPro to prevent the CEL? Thanks!

Anybody has any idea what high current output from the oxygen sensor heater on bank 2 is? I found this with the OBDII scanner. Where is the heater located and would this also affect the K-Pro dataloging? Thanks!

There are no relays in the ecu or on the K-Pro board. Do you hear the clicking when trying to crank the car?

I would suggest trying your ecu in another vehicle by clearing security in their car and then uploading a new base calibration. If the problem goes away it will tell you that it is a ...

From your last datalog (several weeks ago), there is a problem with the charge system / battery. When graphed the voltage should be almost dead flat at 13.8 to 14.2V (depending on temperature).

Does this mean that it is the alternator? I think the alternator should just work or not work. I have ...

who did you get the kpro from?

also, i doubt there's anything wrong with your car electrically, its probably either a bad ECU or bad Kpro, maybe a surface mount resistor got loose, who knows. you should contract the dealer/whoever you got the kpro from before sending it to hondata, they'll charge ...

After changing the battery, did you clear security and then upload a fresh calibration to see if the problem goes away?

I cleared security and reloaded the calibration. I even reset the ECU by pulling the fuse. But nothing takes the CEL away.

There is clicking sound like the sound from a relay ...

Flustration will never go away with K-Pro!

I have just redone all my groundings and changed to a new battery, just hoping the CEL will go away. But IT IS STILL THERE!

I figured out there was 80% of the time the CEL was on after starting the car. So the CEL is not always on.

After driving for ...

Should I just unplug the ECU and measure the voltage at those pins when cranking? Thanks!

Any idea which pins I should use to measure the cranking voltage? Thanks!

You need to measure the voltage at the ECU when cranking the engine over as that is what is really important. If it drops too low it will cause the error you have received.

You should always tune out all knocking unless you can be sure it is not just picking up some other mechanical noise.

Which ...

Would anyone be able to answer my question? Only few knocks on hard acceleration, no knocks on normal driving. Thanks!
