TPS sensor issues, fed up - Can i run without it? Options??
Dave/John or anyone else.
please read
I've been having some on and off TPS issues since I put on my Doug Fab intake manifold and 90mm throttle body. As of lately, the TPS has total failed
What a pain running a 90mm TB! (TPS issues)
I don't have the NEMU nismotronic so I can not run MAP (not sure if this would help my issue) I'm using tunercode with basic board.
I have had a bunch of driveabilty issues with this massive TB (caused by TPS). Normally as you drive the throttle opens and closes up to 50%. With a BIG 90mm TB my throttle only moves like 20% to do the same now. So I'm always into
"FUEL CUT" which I solved for now. Besides that I don't really get much accel/tps enrichment because the TB doesn't open much now while I drive it (unless WOT)
I've messed with this and that and have made the issues better but driveability is still a bit off from the stock sized TB and TPS
ANYWAYS.. TPS has totally shit the bed now. It was running like TRASH. I unplugged it and the car has worked the best it ever has in a few months :???:
What can I do, or should I do?
I'm not going to make any less power. Timing map is still used and i'd only be missing the Alpha/N feature from the Fuel Map right? No biggie, seemed to cause more issues then help. Car isn't running lean when I get on it btw
What about idle? I can just make sure I'm at 15 on the main timing map at idle, to match ignition timing can't I?
I wont be on TPS CLOSED IDLE TIMING but that's not a big deal is it?? I'll just do what I said above^
I don't use the IACV with this manifold just the valve under the intake manifold BTW! Just a note!
IDLE ADVANCE/RETARD will be disabled right? But I don't even use the IACV and have the TB screw set to 1000rpm and is fine HOT/COLD... no stalling or anything. I had previously set both idle advance/retard to zero because I have big CAMS.The car starts up fine cold or hot even here on the east coast
So should I buy a new one or leave it unplugged?
Is there anything in the tune I can change to help if I leave this unplugged or even if I buy a new one? This motor is n/a and will not see a turbo.
THANKS!
