Hi all! ~excited to join the community.
Bit of backstory...
Some Japanese bloke decided that the passenger footwell was the ideal place to locate the factory ECU, 20 years of 'British summers' later and it no longer enjoys swimming... or for that matter, working.
For the same cost as buying a second hand ECU, ignition barrel, immobiliser controller, and locks for the doors, boot, centre console, and glovebox, I thought I would give a Speeduino a go. It also gave me an afternoon of soldering to break the boredom of lockdown. I have a 0.4.3c board with the dual VR conditioner fitted.
I'm struggling to find much info on running a Speeduino in a mk2 mx5, I highly doubt I am the first to try it!
Is there much difference between the NA8 and the NB8A?
Does anyone have a base map?
Any pin to pin wiring instructions would also be greatly appreciated!
I have got the Mazda wiring diagrams, and have sussed that I have 2ch of spark, 4ch injectors. I also have heated O2 sensors, not sure about how the heater circuit is run though...
What do I do with the EGR solenoid? Is it a case of EGR delete or is it something TunerStudio can handle?
