You're pretty much doing exactly what we did back in 2002 when we developed the Mk1 RS, ie chasing round the Ford Parts bin to find stuff that can be bodged together to make it work.... ;-)
(TBH, i'm bloody glad i've never had to use an Rcon ever again!)

It wasn't a bodge! In the end Ford spent £300k on reworking the code to adopt boost control for the EEC-V.
All the earlier iterations were bodges though, I'll give you that!
Do either of you know what sort of RPM the FRS EEC-V ECU can cope with? Will it work with 8k? All the earlier iterations were bodges though, I'll give you that!
I've been told there's some kind of limitation restricting anything above 7k, which sounds low.

It's over a decade since I worked on the project, so there's nothing that detailed left in my memory! I can't see why it wouldn't run to that speed, limiter notwithstanding. Nothing stopping you from testing to see what happens - just inject a dummy encoder signal into the cranks sensor input - the sort of things that arduinos do in my life these days...I've been told there's some kind of limitation restricting anything above 7k, which sounds low.

Good idea, thanks. Excuse for me to play with an Arduino 
The std lookup tables obviously will only be referenced to 7krpm (7200 rings a bell for some reason), which might be what people are talking about, but you need to just suitably modify the Axis lineariser parameter to have valid interpolation above that. AER might be able to remember where the std limiter was set? (6800??)
I've probably got a pre-production memory map archived somewhere (it won't be fully accurate for the production release, but there is a good chance it's just an ROM index offset away) I obviously can't just give it to you, but i'm sure if you wanted to know where specific values were located, i could give you some hints.........

Thanks Max, much appreciated. That's over my head but I will discuss with Sabre.I've probably got a pre-production memory map archived somewhere (it won't be fully accurate for the production release, but there is a good chance it's just an ROM index offset away) I obviously can't just give it to you, but i'm sure if you wanted to know where specific values were located, i could give you some hints.........
To make life easier with mapping etc, you can buy a single ecu code from SCT (superchips custom tuning - not to be confused with superchips in the UK) this translated all the data for you and allows you to rescale the rpm axis so it can read higher, obviously if you go too high it will end up loosing defination. but an extra 1000 rpm will be ok.
It never used to be that costly either. will save some messing around?
