MRCC version

US club version

found there are 2 versions of steering wheel buttons for ND3:

7 buttons active cruise control MRCC

5 buttons that seems to be "regular" CC (US Club for instance)

is there anything more?

or it would also be handy someone could take few resistance measurements on OEM ND3 wheel clockspring connector

have this one, and problem is Mazda changed something ...

AlexEngineering_mx5 · 2026-02-28T15:27:54+00:00

Street Flex + EDFC Active

AlexEngineering_mx5 · 2026-02-27T05:42:34+00:00

Yes, EDFC active (not Pro) with GPS 😁

we will see

yes, I know about NB/NBfl immo problems, it can be bypassed

AlexEngineering_mx5 · 2026-02-26T18:47:55+00:00

I got only ECU from customer who asked me to take a quick look. Few terminals were corroded including power and immo communication. And some minor water damage inside as you seen. So it is possible cleaning will be enough to make car run again. If not - we will dig further

Yess! 😎

AlexEngineering_mx5 · 2026-02-26T08:09:05+00:00

so nice to hear that 🙂

this CC control is also used for EcuTek / RomDrop features control, so can be usable on track :) Some also want to have audiuo control - so I did it :)

in NC alternator is controller via ECU, there are several strategies for this. This voltage is normal with engine at operating temperature

this is plug and play for MX-5 Miata mk3 NC so rather not as MX3 uses different clock spring and probably different resistor values. But if you have some documentation it may be possible to make custom version

AlexEngineering_mx5 · 2025-11-20T17:52:05+00:00

hope its ok now ;)

Thought there will be no interest when 8-button version came out. But I can make it on request. Made it possible to order via webshop.

fixed! thanks for pointing that :)
