Re: NA Miata EcotecMiata Race Car
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.

Re: NA Miata EcotecMiata Race Car
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.

Re: NA Miata EcotecMiata Race Car
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.

Re: NA Miata EcotecMiata Race Car
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.

Re: NA Miata EcotecMiata Race Car
Is it possible to add something like this screenshot to the ETB system? This is allowed TPS error percentage in the OE GM calibration.
