Stock-tuned 1995 LT1 Datalog Recording?

Post by meissen »

Hello out there!

Could someone with a 1995 LT1 that's relatively stock-tune share their datalog recording from TunerPro? I'm trying to diagnose an issue and frankly I don't know what the baseline readings should look like.

For example, I have a monitor set up for BLMs with left and right BLMs as the inputs. During one recording while the car is idling, the BLMs were all over the place from 0 to 250. I turned the car off and immediately turned the car back on and my BLMs stayed at 128 even... no change. Turned the car back off and then back on and the BLMs returned to bouncing all over the place.

I don't know if the even 128 is right or if they should be moving all over the place?

128 is a proper value.

it sounds like your ADX needs some refinement so that a bunch of the other modules that are chattering on the ALDL circuit quit using it so you could datalog.

Thanks! I think you're right - I downloaded an ADX file off of TGO and it seemed to run smoothly.

If it's the ADX I did it works on all LT1, but some need to connect and get's bad data, disconnect and reconnect and get's good data. Haven't figured out how to make it work on all yet.

Thanks - I didn't have any problems with it, though, worked like a charm right from the start. :)

:D

So you have a 1995 LT1, but what car? Trying to figure which works and which doesn't ... first shot. They all work second shot...
