TuneECU vs. OBD2 TPS Parameter???

[bcar00]

I'm in the process of messing with my Rockets tune (because I do that with every bike i modify, not because I think I'm going to get anything out of it).

I'm welding a Wide Range O2 bung in and I'm feeding the signal into OBDLink app (along with ECU data) to then use to generate full range calibration data (will document and report the results)

Currently, I'm stuck on how to record TPS such that it correlates to the value in TuneECU. ALL of the throttle related OBD2 parameters do not match TuneECU's TPS value.

"Commanded throttle actuator A control" is the closest, as it goes to 100% at WOT when TuneECU says 100%, but it consistently reads just under 2% at closed throttle, when TuneECU reads 0%.

Since this is predominately a throttle based control system (except under 4%), I'd rather not make assumptions. This is digital, so If we're off one place, who knows how far we're off at another condition. They should be spot on.

I know it's a long shot, but has anyone seen anything about how Tune ECU goes from actual hardware values to TPS in the software?

To answer the obvious question, I cannot log data in TuneECU directly, as I cannot feed in the WIde Range O2 signal to TuneECU.

Just for reference, here are all the Throttle relates parameters that react at all:

That's a very good question for the tuner guys like Ulf Penner. You might DM him and post his answer.

all i know is that on most cars and the rocket the throttle is never set at zero they always open them a little because they tend to stick when set at zero
that is why the tps is ( most of the time) the tps usually reads around .5 volts instead of zero
different trucks will run between 1.o and 4 volts
i never paid much attention to the rocket but it is set closed throttle .52volts and runs at around .62volts do not have any idea what wot is volt wise or % wise.
maybe we will find out
are those figures actual or out of a book?
