RHD TPS and Micro/Megasquirt

[jpgroth]

Those of you that are running the RHD throttles with microsquirt or megasquirt, are your TPS calibration values correct? I have swapped wires a couple ways but cannot get my closed throttle value to be lower than my open throttle value. Sounds like it's okay to run like this but seems odd that swapping wires doesn't reverse polarity?

Try this. Al sent it to me today.
The connector will now be installed when I make the TPS harness for him.

Josh,
If the TPS signal is going in the negative direction, the +5 & GND are swapped....Swapping the 5V and Ground leads will then reverse the polarity of the signal....It sounds as if your TPS may have the Signal wire in the wrong location...or that your swapping the +5 and signal or...? just to be clear to those reading this thread....... Josh bought the ITBs/controller second hand and my understanding is that he currently does not have any documentation to follow. We have been talking, via email, for a while now and I have been helping him a bit with his install/tuning. Based on our recent discussion.....I am sending him a copy of my install and tuning guide, along with the rest of the doc package i typically provide my customers. I appreciate your offer to review the doc package and provide me with your feedback.

regards,
al

Thanks Al and Dennis. Swapping the +5V and the GND did the trick. Yes, thank you for sending over your prestart documents Al, I will take a look at those this week.
