i posted this in hp tuners as well but i figured id ask here as well. my lc-1 w/b went hay wire the other day after i tried to use the lm programmer. i was trying to do a free air and re program it cause it was off a little bit. how do i get the lm programmer to work? do i use a serial to usb cable?
if so its not reading that the w/b is there. it is saying "please connect the device to a serial port and switch it on". also included is my logs with the truck running and the truck off with the key on. the w/b readings are all over the place when the truck is on and off. i have had this hooked up and operating for almost a year now with no problems. i might be wrong but i think the readings are messed up because it needs the lc-1 needs to be reprogramed. shed some light please.

 

someone help...................

 

what are you using for grounds ?

 

the blue and white wires are grounded under the dash. the white wire was grounded to the hp tuners, till the other day. do i need to have hp tuners on before i go to open lm programmer since i have alot of wires going to the mpvi interface. i might try to use a different eio input to see if i messed the tuner up.
