well my ECU died somehow and I replaced it with another one. for some reason I keep getting 'programming voltage too low' I ran a 12V wire to the flash block. the battery is over 12 volts, and the ECU power supply is also 12 volts. I have no clue where else could have low voltage? I've tried this on TWO separate ecu's. any input? I've tried different USB cables, and reinstalled ECUflash. I'm stumped!

just re-pinned and soldered the reflash connector and tried to flash the ECU with a charger on the battery and no luck. this ECU last worked on a 2002 USDM wrx. I have a 2003 USDM

According to this http://www.scoobypedia.co.uk/index.p...ctingToYourECU
the 02 and 03 ecu's use different flash blocks. Did you try both pin configurations?

I had this same issue. Turned out to be a Tactrix software issue. What version of their software are you using? I thought they solved it with an update last year. I started a thread on this issue a while back.
