EBL and ZT-2 Tuning
Guys,
Just an FYI. Recently I ran into a problem with a Code 22 showing up (Low TPS Signal). Finally, I tracked down the issue to the ZT-2 controller. I had tapped the TPS Signal line from the ECM and going to the ZT-2. For an unknown reason, the controller was affecting the TPS Signal. I was getting less than 5v for the reference, and WOT would only show 2.6v TPS. RBob was around to see some of the effects of this.
Bottom line, I unhooked the ZT-2 from both the TPS AND MAP signals for the EBL. Problem solved.
If you are having an issue with TPS signal using the ZT-2, try unhooking the controller.

Dominic.................that's a strange one huh?
I wonder if some of the things that I have hooked up are what's giving me fits with the Dakota Digital speedo converter. I did a search and found out it is not just me as the posts went back years.
Thanks for the heads up.
