Help: LB7 dsp5 switch

[Clay A.]

I installed a lb7 dsp5 switch today on my buddies truck and the base and the first dsp setting works. But i can not get the other three to work. I have modified the dsp tunes but the last three all seem to run like stock. Any suggestions on what i might have done wrong and how to fix this problem??

Thanks!

Check the pins and make sure they are in the rite spot..

And make sure the voltages in the DSP5 tune correlate with the ones on the switch.

Yes connect to scan and check voltages to see if they change with the switch change.

voltages are all in the right ranges and they change with the switch. red wire pin #49 and black wire pin #69.. is that right? I just dunno what it might be because the first 2 work fine but the last 3 don't but the voltages are changing.

And you checked A0142 A0143 and so to make sure they are set correct?

How about A0146?

you did a full flash operating systems wheb you flashed the tune?


I f you have voltage and its changing id say its something in the tune

69 and 49 in the blue ECM is correct on a lb7

Yea everything is right.. its just not running the tunes in the last three positions. What could be in the tune thats making it not work? On the last setting I made a lope tune by just adjusting a cell in the TBIQ. The voltage is .50 which is more than 0 and less the 1.00 so it should be changing. But it acts just like stock. Also I set it up just like the tutorial said.. I made the base dsp did a full flash then adjusted the dsp tunes and did a regular flash.

When you made the changes to 2 3 and 4 after the first full flash, were you doing full flashes every time one of the mentioned were changed in any way? Full flash required on my lb7 every time I change the dsp2 to 4.

ah.. that should be the problem. I'll give that a try. Thanks!
