I just finished the install and even made a base map with the car. Beware TT Z's, the Procharged Z is coming strong with 16psi!!!

Specs:
8.5 CR CP pistons
Crower Rods
Procharger 9psi pulley (16psi pulley soon, already in my hands )
AAM Complete fuel return system
550cc RC injectors
Emanage with Pressure, Ignition, Injection, RPM adapter and Support Tool
AEM Wideband

The wiring went really well with the emange thanks to all you guys who posted the wiring diagrams. I double and triple checked everything. The emanage right now reads everything from MAF volt. to Ignition but NO TPS.

I checked many times that the GREY wire from the Emanage to Pin #50 in the ECU which is a green wire are connected. Its all done correctly. When I do the TPS test in the Emanage parameters I get 0% TPS eventhough the Ign is on and Im moving the gas pedal. All conections were soldered.

Any ideas? The SW rotary settings are 701, anything else that needs to be adjusted inside the emanage? I have ver 1.39 Support Tool and 1.11 in the emanage.

Thanks in advance,

Carlos Ariza.

P.S. Anyone know how to convert MAF voltage (left column) to psi so it would be a little easier to tune before raising boost?

 

I didn't think you could convert MAF to boost. One is the amount of air and the other is the pressure of the air.

 

The TPS input has been eratic on this car with eManage. You dont need it. Just tune either by MAF or MAP...TPS is not needed at all.

 

You can tune fuel by boost in the additional injection map, not the airflow adjustment map. It wants a throttle signal. The throttle needs to be checkmarked in the settings and then calibrated to work right. HTH

But in the add injector map, you can tune MAF vs. RPM. MAF on the y-axis, and RPM on the x-axis. That would not require the TPS single...just a MAF signal, which he already has.

MAF voltage is a very good surrogate for TPS.

 

Carlos:

The gas pedal is not connected to the throttle. The throttle is indirectly controlled by the ECU. They call it "drive by wire".

 

Yes, very true, but WHY would you tune to MAF when you have a pressure signal? You get much better/accurate enrichment by basing it off of pressure. The holy grail of turbo cars is tuning by MAP directly (IMHO). That way, when you hit full throttle but are still spooling, it isn't using a lot of enrichment that it only needs once it gets into boost.

John, you can still use the throttle position signal which is reported from the actual TPS sensor on the throttle body. It's different from the pedal position signal but it works just the same. It (TPS) just happens to not necessarily correlate exactly with the pedal position all the time. We've done this with eManage on Subaru STi's which are also drive by wire.

Yep, that's why car's running enrichment from the MAF run rich in the upper rpms w/o boost.

 

I understand that. But I am saying that you dont need TPS, even to tune with pressure. Either use MAF/RPM or MAP(pressure)/RPM. Just check off the box in the paremeters screen called "greddy pressure sensor", and then you'll have a drop-down in the add injector screen where you can select pressure.

The TPS isnt needed...trust me.
