I just installed a Stage4B Hondata in my car but the TPS data is only logging (changing,showing 0%) when the car is idling. With the engine off, every other sensor reads except for the TPS which shows 26% until the engine is fired up.

Is this normal?

Thanks

Not sure what your asking, but if you are CONNECTED and the car is running, then all the sensors should be reading and displaying in the DASH VIEW mode. If they are not, then click on "LOG ALL SENSORS" from the pull down menu.

When the car is idling, YES the TPS should read 0% (0.45 -0.49 volts)

 

And it does,
But, If I turn the car off and then back to ign I can reconnect to the Ecu and see everything in the dash view EXCEPT for the TPS which goes to 26% and does not change even if I do open it up all the way.

Basically the TPS is the only one that does not change unless the engine is running.

It seems weird to me and I would like to find out if this is normal.

Some people experience problems with the Hondatalogger if the car is running and the logger is connected and you suddenly shut off the car... you can avoid this by first clicking DISCONNECT on the logger and then shutting off the car.

 

i have the exact same problem! The TPS in honda-logger reads 2.54 volts or 51% (i think that voltage is right)... I haven't dug around enough to see if there's really a problem in the wiring or not, but there don'tt appear to be any loose ends...

my car is a '99 Si with p28 ECU BTW.

Well,

I did some testing with another TB. I idled the car and connected this other Throtlle Body.

While the engine is running the Datalogger works perfectly, including the TPS reading. While the car is not running but powered, every sensor except for the TPS provides a valid reading on the Logger. The TPS remains at a fixed value.

My guess is that the ECU does not Scan the TPS unless the engine is running.

 

I don't understand what the problem is, nor why you even care what the readings are when the car is off. THere is no need to datalog anything (i can't even think of a time that you would want to) datalog with the car off.

The Hondatalogger works just fine when the car is running, so what is the matter then?

 

ahh **** i didn't read the first post carefully enough. mine doesn't datalog AT ALL.. i think it's a bad connection somewhere

 

Did you purchase the datalogging upgrade for your system?

 

Completely NORMAL

 

Ok,

I wanted to know if it was normal...Checking the Sensors with the engine stopped makes sense even when logging does not. Calibrating the TPS is a better thing to do while the engine is cold.

Actually, talking about calibration, the manual mentions a screen for calibrating the TPS voltage, but it is not in the software where the other tabs are.

???

Overall the system is running fine but it is doing the "hesitation" around 3000RPMs...
