MaTTSuN Posted March 16, 2007 Share Posted March 16, 2007 ive been going through my electical again on my 81 turbo swap into my 78Z and im finding that the TPS only has 2 wires from the ECU. ive swapped my TPS with a N/A unit and it has 3 Wires comming off is the Turbo TPS diff or does it just have 1 less hookup? Im not sure where my stock one is but i have 2 N/A TPS's im sure they re made the same. im just wondering if anyone knows what order i put the 2 wires Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted March 17, 2007 Share Posted March 17, 2007 I posted this in your other post but will do this for completeness. The turbo ECCS only requires the TPS (switch, not sensor) to have continuity during idle, which I believe is the middle pin and that closest to the cabin. It has an O2 sensor for closed loop and a preprogrammed map for WOT, so it does not require the last pin in the TPS. Mario Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted March 17, 2007 Author Share Posted March 17, 2007 ahhh so maybe its my O2 sensor giving me the problem. does the water temp sensor control anything to do with fuel? I shall get a new O2 sensor and go from there. Ive heard of some guys say there car runs better without the O2 conected how is that so? maybe they dont have the stock ECU... maybe thats why i never got a "new" new one i replaced it a lonf time ago but may have damaged it... thnks mario Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted March 17, 2007 Share Posted March 17, 2007 Don't get an O2 sensor without fixing the CHTS and the water temp sensor. Both are used in the calculations of fuel mixture! If you put on a new O2 with these other sensors out of whack you'll foul the O2 sensor FAST!

MaTTSuN Posted March 17, 2007 Author Share Posted March 17, 2007 maybe my O2 is fouled my chts works the water temp sensor isnt for the ecu from what i have read i think the O2 is the problem Quote Link to comment Share on other sites More sharing options...
stagefumer11 Posted March 17, 2007 Share Posted March 17, 2007 maybe my O2 is fouledmy chts works the water temp sensor isnt for the ecu from what i have read i think the O2 is the problem 1. Water temp sensor. = ECU sensor. 2. Water temp sendor = Dash temp guage. Maybe read again, Just unplug the o2 sensor and see how she runs Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted March 17, 2007 Author Share Posted March 17, 2007 ive tried unpluging the O2 many times it changes nothing i unplug the CHTS and it dies are you sure the water temp goes to the ecu? how far back should i mount the O2 sensor i think i have mine a little close but i think the stock one is right off the turbo right at the bend ill have to double check and maybe mount it futher away from the turbo Quote Link to comment Share on other sites More sharing options...
