Hondata

Been using my S300 for over a year now without problems. Now it's giving me a solid red light on the s300 and a solid check engine light, but when I connect my laptop there is no codes stored. I can't upload or download any calibritations, also it seems like it's datalogging by itself even tho the on-board datalogging is not enabled. I tried the s300 ecu on my other bone stock integra and the car starts up fine but still the solid red light on the ecu and the check engine light. It currently has a calibration for a turbo car with ID 10000 injectors and hondata 4bar map sensor and it makes it idle perfectly as if it had the oem ecu in there which it shouldn't be doing that since I can't even start my turboed car with the s300 ecu.

- serial number is S300-12364
- Integra
- P28
- Turbo, ID 1000 injectors, Hondata 4bar map sensor

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

Using version 2.1.1.0

Download the most recent beta version from the downloads section of our website, then to to Online and choose erase ECU. When that finishes, close the program, reopen it and then go to New Calibraiton and upload a brand new calibraito to the ECU and see if that corrects the problem.

When I connect the laptop it's showing as the s300 online but I try to erase the ecu and it seems like it's doing it but when it supposedly finishes erasing I get the message that it did not erase.

Send an email to support <at> hondata.com with the following and I will issue an RMA and give you further

Description of problem:

I have the exact same problem, S300 been running perfectly and since the last time I tried to connect to the S300 it didn't work, I tried with another S300 board and it worked perfectly (Just so I knew it wasn't the ECU)

Just sent an email to the support team :)

Thanks,
