Re: 1993 Mazda Miata
Its mre pin 35 or GP1 i think. What do your options look like? I have played with mre48 in a bit.

Here is an example of my tune:

Re: 1993 Mazda Miata
That looks right. You should see a priming time reaction from the pump.

Hi All,
Does this ECU have the capability of using an output for boost control?

Re: 1993 Mazda Miata
Guys,
To use the Kia TPS, do I have to switch wires/pins around? I think I read that somewhere but for some reason I can't find the info.
Thanks

Re: 1993 Mazda Miata
I believe yes. Kia tps has a different pinout and will damage things if not wired correctly.
Best to double check anything like this.

Re: 1993 Mazda Miata
So in this thread:
https://rusefi.com/forum/viewtopic.php?t=1908
It looks like I have to switch two pins around, and remove the R22 10k resistor?
If I just get the popular BMW TPS (used on speeduino and MS), will it work without having to do the above mods?
Thanks

Re: 1993 Mazda Miata
I *believe* the KIA and BMW TPS pinouts are identical. So either way you have to do the mod. Same for MS.

Re: 1993 Mazda Miata
this is not a sorcery analog TPS (throttle position sensors) are simple potentiometers. they have 3 ends let's label them 1,2,3. grab an om meter and measure resistances between legs and move the throttle, there should be one pair that is not changing resistance for example 1,2. one of them must be tide to GND other to 5V. the one remaining must be attached to TPS of the MRE....

Re: 1993 Mazda Miata
if you plug the kia tps right in, you will find that the calibration values are backwards due to the switched wires but it works perfectly fine.

Thanks, and I'll still have to remove the R22 resistor?BeerMoneyMotorsports wrote: ↑Thu Feb 17, 2022 4:21 pmif you plug the kia tps right in, you will find that the calibration values are backwards due to the switched wires but it works perfectly fine.
Re: 1993 Mazda Miata
If you don't remove R22 the values will fluctuate because of unstable voltages, but it's perfectly usable
Also I did the pinout swap, but the values are still backwards
