engine cranks, but won't start

[danx]

Hello,

I just installed a 05-06 KPro into my 06 RSX-S, and now the car cranks, but will not start.

- I replaced the primary O2 sensor with an 02-04 version.
- Uploaded the 05 CAI kal that came with KManager, unchanged.
- Immobilizer is disabled (check box was already empty in the kal I uploaded)
- Fuel pump seems to be working -- I removed the gas cap and did hear some sound from that area after I switched the ignition to "on"; I didn't follow the rest of the service manual's procedure to check the PGM-FI main relay (I didn't touch anything in the fuel system during installation, so this seems unlikely).
- KManager seems to communicate with the KPro - it says "On Line" and "Ignition On" when I plug it in. I was able to upload and download with no errors. I'm running Windows XP under VirtualBox with USB passthrough.
- I tried Erase ECU to clear any possible security per http://hondata.com/techkpro_troubleshooting.html ... it returned an error (I assume that means Protect ECU wasn't set)

other relevant info:
- serial number: 4191 EDIT - this was what was written on the front of the box; serial number in the ECU is different (see post below)
- KManager version: 1.4.1.0
- the calibration: 2005 CAI kal ("k20a2-rsx-2005.kal")
- vehicle: 2006 RSX-S, stock except for CAI
- what sort of ECU you are using: I'm not sure ... I bought the KPro used

Is there anything I'm missing?? Any other suggestions to help out a noob?

Post a picture of the inside of the ECU, K-Pro and harness.

Download the most recent beta version of software from our website, then try clearing security, then go to new calibration and upload a new calibration making sure you disable the immobilizer. When it finishes, take the key out of the ignition before starting the car.

Spunkster,
Just tried it -- it didn't work.

I downloaded the cal from the ECU and compared it to the cal I uploaded ... here are the differences of note:

Line 21:
SoftwareVersion=5207
SoftwareVersion=5136

Line 23:
Checksum=1112211714
Checksum=1586364804

Line 569:
LaunchMaxSpeed=2
LaunchMaxSpeed=3

I'm guessing those small differences are the result of the uploading/downloading process, so it seems the cal is being correctly sent to the ECU.

Any other thoughts?

Okay, found one more clue to the puzzle. I pulled a coil and checked for spark while cranking the engine -- there was none. So the question is, what would cause my coils not to fire?

[Spunkster]

Please post the calibration you are uploading. Do not provide a link to some other wibsite, just post it here.

[danx]

Cal file attached.

Another noob question ... do I need to unplug the immobilizer (from beneath the steering column)?

[Spunkster]

What version of software are you using now?

[danx]

Version 1.4.5.7, May 2011

Will the stock ECU start the car?

How long does it take to uplaod to the ECU?

[danx]

The stock ECU was working fine before I installed the KPro. I can re-install it and check it out again when I get home.

Do I need to switch the primary O2 sensor back (to the 05-06 version) before I attempt to start the car with the stock ECU? Or can I safely start the car with the stock ECU and 02-04 wideband O2 sensor installed?

When I cleared out the ECU last night, it took about 30 seconds. Uploading also required approximately the same amount of time.

[Spunkster]

Clear security again, but when it is done, close the program completely and reopen it then go to File, New and open a fresh calibration an upload it. Uploading should take about 2 minutes.

The O2 sensor will not cause a major propblem just for starting the car.

[danx]

Okay, I cleared security again and reset the computer before uploading. The upload took ~1.5 minutes. Still no start.

I plugged in my stock ECU and the car fired up right away.

Is it too early to start asking about Hondata's service/repair/warranty policy? :(
