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
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.

Re: 1993 Mazda Miata
The firmware has a section for the fuel pump control that will allow the ecu to power the fuel pump relay for priming and then whenever it sees rpms. I believe you need to go from 2T on the ecu to 2O on the chassis side. Easy with your boomslang. Then jumping the maf connector. image.png Awesome! T...

When I want to change to MAP, is the only setting I change in "Base Engine Settings > Fuel Strategy > Speed Density" ?

Ok guys I hooked up the MRE48 again and did the Bench Test, I can hear clicking injectors when I went through each one. I just can't tell which ones are clicking.
Can I try moving the jumpers?

Re: 1993 Mazda Miata
I reset the board to the base map, corrected the MAF pin as suggested earlier in the thread and let the car warm up really good with the stock ECU.
I currently do not have a wideband installed, it's running on the stock o2 sensor.
Thanks,

Re: 1993 Mazda Miata
Hi Andrey,
I hope you are doing well! I want to add that the car runs perfectly fine when I put the stock ECU back in, so I don't think it's a spark or fuel delivery issue, I'm thinking it's something with the tune or board?
Thanks

Not sure what I've done but I have had no luck getting it to start again. I've loaded my original tune without the VE adjustment and made sure the MAF pin was set correctly but the car just keeps cranking.

Re: 1993 Mazda Miata
Hi guys, trying to get back into this project.
When removing the stock AFM and using a GM IAT, does the fuel pump pins have to be jumped at the connector? If so, does this mean the fuel pump will always be running when the car is on or is there another method of control?
Thanks!

Re: 1993 Mazda Miata
I've always suspected my car for some reason is running rich, even with the stock ECU. Gas mileage is not great and there is a stronger fuel smell when warming up. Would a bad O2 sensor be causing this?
