Setting up the TPS on duel TB

marco the steem engine · Sun May 20, 2001 6:38 am

I have set the linkage correct, they open the same time/amount and close the same time I have a question, when getting the engine to idle you open the throtalBodies alittle to get some air in the engine and meter the fuel acordinly , but my Wolf3D senses around 25TPS and 20% load because I adjusted the TPS to 0 when the Butterflies were compleatly closed!
Should I leave it like this or should I recalabrate the TPS to Read 0 when the engine is idling?
I'm using the TPS for LOAD and ACC inrichment(no map sensor)
Thanks for any Help.

I calibrate my Haltech to zero after I set the linkage. I then double check for zero after the engine idle is set. I also double check for WOT when all done.

Will the Wolf set to zero thru the software? and full throttle? It seems to me it should.

you set the TPS manualy for closed throtal and electronicly for WOT
thanks Tom
How do other people set the idle?

Guess that's one of those differences between the Haltech and Wolf systems. Mine is really easy to set, very user friendly.

Sorry couldn't help.

I set mine at around 4 or 5 at idle. You should be able to move the sensor by loosening the two screws that hold it on.
If you don't want to do that then re-program your TP values starting at the throttle positon that the car is idling at.

Hi
My Autronic SMC does it all in the software.
1. Ignition on, engine stopped
2. Disconnect TPS electrical connector for at least 5 seconds
3. Reconnect TPS electrical connector.
4. Ensure throttle is closed for at least 5 seconds
5. Fully open throttle for at least 5 seconds .
The new limits are learnt by the software and stored.

I concur with Chuck. The Wolf TPS is set up manually for the idle position and via the on-board potentiometer for WOT. Loosen the two screws securing the TPS to your throttlebody and rotate it until the TPS value on the Wolf hand controller won't go any lower. To be on the safe side, rotate the TPS in the oposite direction until the value increases by one (this is sorta like "preloading" the TPS). Then adjust the potentiometer at WOT to register "98".

As for using the TPS to determine engine load, I cannot offer you any advice. My engine is turbocharged and I *must* use the MAP sensor for load. However, for multi-throttlebodies that don't share a common intake manifold plenum, using the TPS for load is the best way to go.

FWIW, my minimum TPS reading is "9", while the maximum is "97". According to Steve at Wolf, WOT doesn't have to be exactly "98" (at least for applications that use the MAP sensor for determining engine load).
