So this is an E6X with external 3bar map sensor, running stock fc coils.

now the throttle was calibrated and re calibrated so that is good, but when I am on the hwy especially the car feels like it stubles for a split second.

So i data logged for a bit and this is what i see watch the TPS you can see the tps go to 0. (if you need the whole sheet i can send it )

If i am not mistaken the tps should never go to zero voltage. This issue happens when holding thottle steady for a prolong period or at idle.

Is this a tps issue or i need to adjust some settings?

 

What TPS are you using? I would guess it's a bad sensor, but this could also be in your wiring (connector usually) or the ECU itself.

 

haltech TPS...... how do u suggest I test it to tell if its the wiring, sensor or connecter.


i went out for a run and it will not do it unless i am on the highway for a long period of time like 30mins at the same speed + RPM

 

You would need to log voltage separately from the ECU to really test it. If it's this sensor, then I'd be 99% sure it's a bad sensor. There was a run of bad/failed sensors which led to Haltech switching to the current, much better Bosch units.

 

i had problems with my connector and so i wired it up directly and fixed the problem.

 

Can a tps have dead spots through the sweep?

 

Yes. It's simply a variable resistor.

 

Is the Haltech TPS a direct bolt on for an FD Throttle body?

 

no.
