Tweecer ECT problems

Been playing around with the tweecer but I have been having problems with my ECT when data logging. I did an ACT relocation to the lower intake for starters and now when I datalog the ECT and the ACT are always the exact same temp. Does this make sense? The car is running rich right now. Not only that the ect does not continuosly rise while car is warming up. I have to stop data logging and start again to make the temp change.

I checked the sensor for reistance and it seems to read however I guess it could still be screwed. Does the ect fault to the act temp??
Any suggestions

Alright still having problems. Disconnected the ACT and plugged in a new sensor that was sitting in atmospheric temperature. It read 60* f on my datalog but so did the ect. I warmed the car up and the ect still wouldn't move. Neither value would move. So I took a new ect sensor and with the car off key on datalogging I warmed up the ect sensor (new one) and the ect still would not move.

Also I have been having problems with my fuel trim. Seems to stay on 1.00 in closed loop now. It was working a few days ago before I had this problem. This is getting frustrating. Anyone have any suggestions.

I am thinking that it is either a wiring or software problem now. It would be nice to fix this I want to drive my car before the snow flies.

I cleaned the j3 port well with a razor and some contact cleaner. Anyone had wierd problems like this if it is not 100% clean. I'm kinda lost.

There used to be an issue with Cal Con and Cbaza

You could dlog act OR ect but N O T both



Ya might see
if you can get error free readings if only dlogging one at a time
