TPS problems…but solution!

The car starts SMS revs perfectly but a nagging problem is I would not see any indications on the software of a TPS signal below WOT. The problem produced odd behavior but I believed it was just how the Hondata ecu worked.

After driving and not seeing the tuning results in the data log I decided to pull the tps and flip it 180 degrees. I’m doing so I noticed the connection point was incorrect and the sensor was not making contact with the throttle shaft until 25% of the sweep happened. A small correction and things were showing TPS motion the entire way through the range. Timing is more responsive and drivability is better.

One problem remains. Under WOT I am not seeing boost over 1 psi. The watergate has a 7 psi spring in it and so something isn’t kosher. The hunt continues…
