I have a question on TPS sensors, is it true most of them read from 0 to 5 volts? The reason I ask is from my research the TPS sensor that was supplied with my TWM throttle bodies is a Rover part ! Not exactly a over the counter part. I have the old ( bad ) one that I plan on taking to local parts ...

It turned out my TPS sensor was bad. I replaced with another one and she fires right up. Thanks for the link.

Well today I noticed that the throttle position % gauge reads about 90% at idle why would that be? I'm idling at about 800 rpms so I know my butterflies are not open very far. But when I try to calibrate my TPS the idle setting auto populates around 700..................what gives?

Well this is a new problem. The car is a Porsche 911SC 3.0 litre with MSII version 3.0 with Megatune 2.25. The car has ITB's and has been running pretty good except a stubborn idle. All of a sudden yesterday it runs like crap, hunting at light throttle setting and then it died on me and wouldn't ...

Yes it's a 6 cylinder and they are high impedance injectors. I will try the 2 squirts alternating and see what that does. Thanks for the suggestions.

It is a normally aspirated engine. I thought going to 1 squirt per cycle would mean less fuel? I have adjusted the VE table to lean ( poor throttle response ) and then slowly richened until good response. I have minimal AE and I'm running in Alpha mode vs. speed density. I'm also running 100% TPS. I ...

I am running a Porsche 3.0 liter with 46MM ITB throttle bodies,stock cams and compression and 30 lb. per hour injectors. I can get the car to run good but not great it just seems to be a little off. When I purchased this EFI "kit" the seller was going to supply 20 lb. per hour injectors but couldn't ...
