Hondata

Ok so I will send the current ECU with KPro installed for troubleshooting and upgrade. Then if you confirm the ECU is bad, I'll send another ECU. IS this ok?

Ok the customer says he wants to upgrade to v4 but my question is what if the ECU is bad and when you replace the v3 with a v4 it still has the same problem? What are my options at that point?

Unfortunately I don't have access to another KPro'd ECU. Do you offer this service? If so what is the cost?

Did the diagnostic logs you received confirm that the KPro is good but the ECU is faulty?

Thank you for your continued support.

You mean remove the KPro and install it in another ECU? No I have not tried that and was under the impression only Hondata did that type of work. I;ve prepared dozens of S300's but never a KPro.

If there is a guide for removing and replacing I would dare to do the swap.

Hello any updates?

Good morning I just sent the information. Please confirm reception. Thank you Spunkster.

I understand we are past the password issue as I can connect and upload a new cal but the LED still blinks red. Remember, the ECU has been erased several times already.

This is what the customer told me: Car was running fine and suddenly lit the CE with code for knock sensor. He tried connecting to his ECU and was asked for a password which he did not have. He called his tuner who suggested erasing the ECU and upload the calibration again and that's when it stopped...

1) Erased ECU
2) Closed KManager
3) Key to OFF
4) Waited 5 mins
5) Key to ACC
6) Load Kmanager
7) Create calibration
8) Immobilizer OFF
9) Upload to ECU
10) Blinking ref LED
11) Only cranks

I connected to the ECU, downloaded the calibration and the Immobilizer not checked (disabled)
I am testing the ECU in my RSX which has a working KPro with the immobilizer disabled so no, it's not in the original car.

Kpro v3 #10877 KManager v4.3.6 I downloaded the customers calibration and the KManager tables reflected this. I re-uploaded but it doesn't seem to do anything. Kmanager recognizes the PRB w/KPRO but does not start - flashing red D1 LED I erased the ECU (cleared security) I created a new calibration ...

Customer gave me his Kpro red board installed in a PNF-A13 ECU stating it won't start and has the D1 led flashing red.

I am going to try to connect, erase and reprogram but I wanted to see what this LED means. Tks.

Thanks again. You may close this thread.

That was it - thank you for the excellent customer support!

Question - Is this option checked by default? I'm assuming yes or the changes will never be stored?
