Thanks for the update. Let me know if there's anything else you need.

I have 4 more, but it will not let me post them. I'm guessing they're over 5mb.

For the love of god people, rather than jumping on the me-too bandwagon give us some meaningful datalogs.

- KManager version (not 'the latest') - 1.3.4.0
- the calibration (as an attachment) - posted
- what sort of vehicle you have - 2003 S2000
- what sort of ECU you are using - PRB
- anything ...

I'm having this same issue give or take a few tiny details. I will post a datalog and cal when i get home from work to help gather info on it.

Hondata changes nothing to do with the water temperature operation in the reflash.
The cooling is perfect now. It had a bubble somewhere in the line that worked itself out the next day.

Does the error code occur when scan tool is unplugged. Sometimes the tool itself can cause the CEL to flash ...

I'll reply for him as he's a good friend and the problem is still present.

At Kraftwerks request, the rev limit was changed to 8200 RPM some time ago.
We used an OBD2 port scanner/datalogger and the ecu shows the car hitting upwards of 8350rpm's before a shift, and this is not hitting redline ...

I only had the kpro in for 1 day before this issue occurred. It was fine for that one day, then all of a sudden the primary sensor starting reading wrong and closed loop started pulling fuel to "fix" it. It literally was running perfectly one minute, stopped the car for 5 minutes, started it again ...

Fortunately I had a wideband installed so I could see what was actually going on. I havent replaced the primary O2 yet (expensive!), so it just throws a CEL after a minute or so (Primary O2 Low Voltage code).

Just a quick question for you. Did your car have any symptoms when this started ...

- serial number of your K-Pro - Not sure, i can look if needed.
- KManager version (not 'the latest') - Not sure(Not tuned by me)
- the calibration (as an attachment) - ECU is locked
- what sort of vehicle you have - 2003 S2000
- what sort of ECU you are using - PRB
- anything about the car which ...

currnetly we have no plugged in the clutch sensor, not exactly sure on how to wire that but I think that might prevent it from working, since the car didn't originally have that.

I would bet thats your problem. A bad or missing clutch switch will prevent a car from turning over. You can find the ...

This one works perfect, adjustable three beeps, set at whichever rpms you prefer. Its super loud too.

No, it will not run with the wrong sensors and yes you must remove the oil pan to get to the crank sensor.

I was hoping it would atleast run in some sort of limp mode just to get it home. We endud up just pulling the sensors off his motor and leaving it there without them. Thanks for the reply ...

Tomorrow I'll be buying a K-pro off of my friend. He totaled his car, so its sitting at a collision center and we'll be doing it there. The car runs and there is nothing wrong with the motor/ecu at all. My question is if i just took the kpro out of his car and put his stock ecu back in, would the ...
