i was out street tuning and i noticed taht between shifts if i paused before putting it into the next gear it goes lean for a sec then goes back to normal, should i worry about it or is it normal?

 

So your throttle is at 0% correct?

 

yep, it dips for a sec and then goes back to normal

 

Sounds stupid, but do you have a lightened clutch? I had that happen on a Del Sol between shifts. The tach would climb about 700~rpms and the PLX would throw out a lean reading. The rest of the map was beautiful so we didn't worry about it. That was early August and he still has no complaints.

I believe the computer puts you in decel mode for that split second you are still in gear with the throttle closed. Most ECU's are programmed to cut off injector duty in decel mode hence the lean reading. Just a guess though.
