ok i hooked my Rtech into my lc-1 via the ecu and veriable input(dont know dont ask!)


so i got the rtech reading a 0-5 volt signal from the lc-1 this is known as the analog outs for the lc-1, yellow and brown wire

i got my analog out 1(yellow) hooked to an analog a/f guage.

this is programed threw LM programer to the following

0 - 5 volts
7.35 - 22.39 a/f

reads perfectly on the guage.

i went in to change the settings for the rtech on the analog out 2 (brown) it showed perfect aswell, mached up to the lc-1's display on the laptop.

it went well, but once i did this. the analog out 1 went to factory default... i went to change it but it would not change, the guage was reading off.

the rtech was still reading fine untill my lap top showed 10% battery life left

after that happend.......

rtech read only 14-16 a/f ratio threw whole sweep, it was also at factory default!!!!!!

so both analogs are at factory default and the laptop wont re-program them at this point.

i tried it both with car running or not running made no difference, the lm programer would not program the analog outs. kept goinngn to factory default.

any thoughts?
ya'll think its just the lap top and its low battery?
