pearlta969 Posted June 6, 2007 Report Share Posted June 6, 2007 A buddy who tunes cars was trying to do my car tonight and he has tuner catts for LT1s. Its the OBDII software and he was trying to get it to read the pcm and it said it failed to connect over and over. I disconnected the battery for about 45 minutes and it re pinged and it started to work and then disconnected. Also, whenever I put the coolant fan relays back in the fuse box, number 1 fan stays running for a long ass time. SOME HELP PLEASE! Quote Link to comment Share on other sites More sharing options...
Guest nasty57 Posted June 22, 2007 Report Share Posted June 22, 2007 did it make a full connection, or just make an attempt and you thought it connected?It sounds like you dont have the comm port set for the right one. I used tunercats on mine and thats what mine did at first untill i configured the comm ports. Quote Link to comment Share on other sites More sharing options...
