ECUTune 1v4 throwing codes?
I just installed an ECUTune 1v4 in my '95 LSi and it started throwing a CEL code 56, which indicates the EGR system (CA). It's not throwing any other codes. It didn't do this before the chip. I've looked over the EGR valve/solenoid and didn't see any vacuum lines off, or connectors not connected, and there's no change in car performance when the CEL comes on. Before I start yanking and replacing EGR components I thought I'd see if anyone else has run into this problem with their ECUtune chip. (A search of past posts was inconclusive).
