Hondata

Last September I sent in my ecu to hondata and had it upgraded from S300 V1 to V3. I also had the capacitor upgrade offered completed. Everything worked fine until this spring when I upgraded the software to the newest version. Now every time I cycle the key (if longer than 10 minutes) my tune will revert to a stock GSR map. Is there a software update in the works to resolve this issue?

Are you only seeing this when you download the calibration, but the car runs the same as long as you don't try to reupload the downloaded file?

I have to upload my tune from my laptop to the ECU every time I cycle the key. How I tell it has reverted to the stock gsr map is when I start it my car idles poorly and is extremely lean.

What is the s300 serial number?

Serial #64041

Any recommendations?

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

Ok I am out of town until next week. I will do as described when I return.

Hi Spunkster,

Have you had a chance to review my map that I sent via your instructions?

Thanks,
Mark
