RM Racing Electronics lucky dip ECU
Discussion
So I bought a supercharged MX5 MK2 which came with a load of bits the guy hadn't fitted yet including this guy ...
Any one had any dealings with these as I've never heard of the brand and not sure if it'll be worth the effort of fitting / if it will cause electrical gremlins as I cant done any bank of maps online.
A google search doesn't bring up much but their site

It'll be a megasquirt based ecu in a custom case with a mazda connector. Perfectly usable, but it will require you to have (or to gain!) a decent understanding of how ecus work and to understand the variables in the tuning software - TunerStudio is very good, but not always the most intuitive to use!
I think describing it as plug and play is a brave claim - sure it may fire up on a base map, but you'd need to either invest a lot of time in tuning it yourself (fun and rewarding if you are that way inclined), or spend a fair bit of cash having someone map it for you. Not all tuners will touch Megasquirt either, but Bailey Performance seem to be recommended (not tried them myself though).

It's been a few years since I did mine, but I remember doing a LOT of reading on the megasquirt forums. There's an awful lot of information out there, and a few good how-to's (if you can find them!).
It is possible to tune on the road to a reasonable degree, but for optimal results you'll need a rolling road - apart from anything else, tuning high rev / high throttle opening areas generally result in exceeding appropriate road speeds fairly quickly... rolling roads also allow you to hold a constant load which is impossible on the road. That said, mine has all been done on the road and track, so it is possible if not ideal.
If you are mechanically minded and understand how engines work (or are prepared to learn) in terms of AFRs, ignition timing, EGTs etc, then it's a very satisfying project!

Can anyone confirm if these ECU's are MS ECU's?
If so, which MS do they use.
I'm amazed by their price.
Their plug and play MX5 ECU is only £289.
I'm interested in their BMW M52 ECU which is a 6-cylinder engine for only £350.
To compare, MS units cost as follows:
MS1 V3 fully assembled = £534 excludes PP http://www.megasquirtuk.co.uk/ms1v3.html
MS2 V3 fully assembled = £534+ excludes PP http://www.megasquirtuk.co.uk/ms2v3.html
MS3 V3 fully assembled = £618+ excludes PP http://www.megasquirtuk.co.uk/ms3v3x.html
The BMW is fully sequential so you would need to use an MS3 to achieve that. I'm scratching my head here, but I don't understand how the RM Racing Electronic ECUs are using MS ECUs at that price.
Their website suggests they use MaxxECU (although they don't specifically say this) but it is advertised all over their website.
They are a comparable price to a MS at 604EU / £550: https://www.maxxecu.com/products/street and their software looks really cool: https://www.youtube.com/watch?v=OK3PIEB1YWE
Any knowledge of this system would be greatly appreciated.

I got a response form RM Racing.
They manufacturer the units themselves and run modified Speeduino firmware.
I couldn't get much information out of them in terms of documentation etc which I find a little off-putting.
I also contacted https://diy-efi.co.uk/ who aim to start making the Core4 M52 ECU very soon. They were a lot more open about what technology that they were using and sent me the following details: https://github.com/pazi88/Speeduino-M5x-PCBs/tree/... (£???)
This units uses the Core4 unit from https://diy-efi.co.uk/product/core4-module (£175)
