ex 2 tune want download to car

[gpp]

i got my tune from chris at jdm for my sc and i cant get it to download to the car.i up graded the drivers and firmware to get it to download to the ex2 itself so is there something else i missed?i did see where with the last firmware upgrade it said to put the stock tune in it but this 1.3 didnt say anything about returning it to stock.

Did you upload the stock (Or other tune that is already on your car) first? Make sure the proper fuses are disconnected and you have plenty of battery.

If you did upload the tune that was on the car first, try flashing it stock then starting over.

Is it a SC tune from the same company you got your tuner through? Are you trying to load a tune from a differen't tuner complely? What, did your battery die once when you tried to load a tune?

well i cant even get the stock tune back in,getting the same timed out message.the tune is from jdm, the battery shows 12.57 volts ,and the tuner is from mike troyer.ive used doug at bama chip tunes on this tuner with no problems.could the port connection on the car be bad?if i reformat the tuner and reload every thing do i lose the stock tune?

i found out i didnt do the up date right since it took about 10 minutes to do it right.still times out though.

I'd call JDM and run through the process with them.
