My TPS reading seems to be RPM related. Even though I am at WOT through the pull the TPS reading goes higher with the rpm peaking from 85-100 depending on whatever, I know not! Should it read 100% from any RPM? If it did sooner would that change any other data like timing? ETC.?THX

 

If you have your foot flat to the floor - it should be 100....
What logger you using - might be slow update?

 

The software that comes with the Euro-Flash. It must be slow as it only gets high, mid 90's near the higher rpm range. I would think it should read 100% whenever the pedal is down to the floor. The car runs fine but right now the 90*+ temps in SW Florida era taking away what feels like 30HP!
Jerry said I could not read the TPS so I reminded him I was using the E/C software.
Maybe I could use a new TPS, the one that goes on the TB? The gas pedal assembly was replaced last September when I bought the car, an SLK32.
I would like to know what timing is normal too. Mine is all over the board down low but usually ends up around 19-20 at peak RPM/TPS. I have questioned why these motors run so little timing at light cruise, maybe 30-32 degrees. That can't help mileage but I guess is what these motors need to have.

 

It does not go ON the TB, it is an integrated part of the TB.
You might try removing the black plastic cover and cleaning the contact fingers and the board runs with some contact cleaner.

 

Thanks, I'll check it out.

 

You could get yourself a Bluetooth OBD2 plug from China for $9 incl. Shipping here and then download Torquepro from the appstore ...$5...and see what readings it gives you.
But most probably the same.
My update frequency on the wireless+app is about 1second but I'm reasonably happy with that.

 

BTW I use a mini usb BTdongle from Amazon, not much knee room in a crossie so need the short one.

Also Torque Pro only works on Android. (have it on my phone).

Is the TPS on your foot or the throttle plate ? Can see the FBW logic dialing it in as the revs climb and it needs "more".
