err okay so i have my red wire hooked up to a fuse in my fuse box (left kick panel) my blue and white wire grounded at a bolt next to shifter. yellow and brown in aux 1 & 2. nothing with the green or black(black is calibration i know). And i entered values into aux 1 in LM programming to 0v 9.5 and 5v 19.5. I used the same thing for my datalogit. now my probblem is when i start logging data I see 9.5 only...

 

sounds like you are getting 0v then

 

Recheck all your wiring with a volt meter.

 

okay i will my question is that... does the system ground have to be somewhere special??

 

okay... i tested the main(red) wire to the main ground (blue) and i got 12v(w/ ignition in on position). then i tested from the systemground (white) to both aux1 (yellow) and aux2 (brown) and i got 5v.


logging data at idel everything says 9.5 driving the same but occasionally goes to 9.8.. then to 9.5 again. it seems to change to something besides 9.5 when i push on brake..kinda wierd. and also sometimes when i'm accelerating it jumps to 19.5 ..also kinda wierd. i have taken my battery out since i have calibrated it... I have also changed the numbers in aux1 in LM programmer to 0v 9.5afr.. and 5v 19.5 didn't do lamda. didn't do aux 2... and in datalogit i did the same parameters. maybe a broken sensor? (i ran it quite afew hours with no system ground in it) fyi
