Identify lt10s hardware/firmware varient

I have been asked to look at an lt10s to work out what is wrong with it. When installed on an engine running an FC CAS and 4 LS2 coils, one of the coils gets very hot. The engine does not start.

I am fairly sure that it is configured for rotary, and after looking on Microtech website it looks like there are two lt10s varient, standard 13b and FD.

I'm suspicious that this LT10s is in fact an FD config, but I do not know how to confirm. I contacted Microtech a few days ago about this but have not yet received a reply.

The only piece of relevant info I can see on the handset is that one of the screens shows ECUid 32.

Might anyone know how to identify what config is on the ECU?

Thanks in advance, Arran

Can you post the screens? The basic setup should give some indication if its setup for the FD or FC.

Hey Arran im not 100% sure but think you need to use the factory FC 3 coil setup with LT10S.

Thanks for the replies guys. Still scratching my head on this.
Microtech have not responded to me as yet and I'm not holding much hope that they will

After looking on the handset a bit more, the ECU ID screen isn't relevant. All that is doing is saying it is on ECU ID screen which is number 32. The tuner would typically input their characters for their shop or whatever.

What is relevant though is the line one screen down form the power on screen, which says Maz b2.0. While I can't find any info from Microtech online about what this means, these two threads mention this same string and are configured with FD factory CAS and coils:
https://www.rx7club.com/microtech-11...0s-msd-724764/
https://www.rx7club.com/microtech-11...k-lt8s-913537/

I tried searching for Maz b1.0 to try and prove the alternative but it looks like Microtech didn't call their 4 coil sequential firmware 1.0.

So it is looking like Maz b2.0 might mean FD
