To be honest the tune changed each time I flipped the wiring/position so I'm not sure which one that tune correlates to. I can redo this if you think it would be of benefit.

Nope, at the moment I am not sure how to use all that data.

How do you calibrate TPS?

I wonder if the issue is with auto-calibrate. Note that you have a 4% split at 24% TPS that's already a huge red flag, let's focus on that crazy split. What is 24% is that ETB resting point?

Can you calibrate manually? Let's try two different strategies and see how it goes:

* let's temporary calibrate ETB resting point ("Disable ETB if engine is stopped" setting) and manual WOT position with your fingers
* fully shot and WOT position with your fingers

Manually holding the throttle closed and open is how I did calibrate it. ETB motor off. Resting throttle is around 20-25% depending on which AV channels are used and which way around they are wired.

Just added TPS split gauges similar to PPS split gauge which we already had - until now tps splits were available in the logs but not as gauges https://github.com/rusefi/rusefi/commit/063495a87010d0070f28801054728092a51d3fc1

Please create a log with manual throttle movement, let's have zero split at 0% and 100% and see what that split does in the middle.

OP, do you have a build log, or more information on how you mounted the B207R ?

I have 2 Miatas and a Saab 9-3 B207R that is running a touch over 300bhp, the car itself is a bit tatty and I was thinking about transplanting it into the miata.

Thanks!

You'll want an 8 bolt flywheel kit for the 2.0L engine. Stock location turbos clear the chassis with lots of room. You'll need to bypass and block off the oil cooler and run a remote one.

Is it possible to add something like this screenshot to the ETB system? This is allowed TPS error percentage in the OE GM calibration.

user can now reduce TPS/PPS split error threshold
