I sent my ecu to hondata to have my green board replaced with the white board V3, they were able to download the tune from my old S300 and the car runs but out of an abundance of caution I want to replace what they uploaded with my original tune file, so do I just simply click open calibration then select my original tune file and click upload? Will that replace my original tune or do I need to click erase ecu first?
I'm having an issue were I try to upload a saved file and it keeps telling( upload failed please try uploading again). I've opened up the ecu everything looks in excellent condition. I replaced the step down harness with a new one didn't change anything. I put ecu in my buddy's car and it does the same also. Any help would be appreciated
I'm looking at purchasing a s300..my question is I have an ek3 with a d16vtec and have convert it to h22a am I able to use the civics original ecu and chip conversion to run and tune the h22a?
