Hondata

ok ive seen tons of post about this with no info on it being fixed, so my issue like everyone else I can not upload a base map.
it lets me datalog, I can download from the ecu but I can not upload I get a try again. ive looked at my board it looks ok nothing burnt that I can tell I have all green checks, its registered, the ecu was tuned in 18 and it sat for about 2 years till I took over I registered the ecu in my name can anyone help since hondata isn't taking RMA's atm



Serial no:21615
im running 2.7.5.0
firmware version 2.01
software verson 2.5.4

Have the capacitors been replaced in the ECU?

I can't confirm they have been.. in 2018 hondata was installed. It was originally a po6 converted to a p28 all the solder links look great nothing looks or smells burnt.. the car was tuned before I bought it.....
I have the green light when I power it up.. also it wouldn't let me erase the ecu

After inspect the ecu the the capacitors look to have been replaced

I would recommend that you try the s300 in a different ECU that is already using an s300 and see if it works in that ECU.
