Hey all, I'm looking for some help with this problem. I'm trying to tune the fuel map of my 1999 3.4 L Tacoma. My scan tool will interface with the OBD II with no problem, but if I try to connect with the ECM, I get an error message telling me to check the connection and make sure that the ECM has power. I purchased the URD MAF calibrator and I can't upload or receive any map data. Has anybody installed one of these before or know something about this problem?
