Has anyone run into problems using the Xtronics Pocket Romulator with the 122747 ECU? I can load my bin into it with no problems, but when I plug it into the ECU I can no longer connect to it with my laptop, and I get a flashing check engine light... I emailed the company and they suggested it might be a problem with the 24-pin to 28-pin adapter I soldered into the ECU. If I burn a 28-pin chip with the same bin though, it works fine.

Weird.
