This Emerald system looks like its seriously well thought out - just had a skim of their website - do I understand correctly that the God of all things automotive known as Dave Walker is involved/behind this company ?
I used to read everything he produced in CCC magazine in days gone by - learned loads from that man. He is a legend.
@Jamo - did you install the Emerald system by yourself - any integration issues to speak of with regards sensors, inputs, outputs etc - what was like to map ?
Reason I ask is for plans on a project car that I must pursue before I die and I'd really like to go with an aftermarket ECU on that. Probably going to be GT30R based - maybe on a stroker - dunno - maybe in a CQ or B4 Saloon shell depending on what comes up. Because of all the options and the fact it might go thru different incarnations of engine topology (cams, pistons, rods etc) then it would be best for me with an aftermarket system.
Early days for planning here - mostly daydreaming prolly - this Emerald thing certainly got me thinking though - looks really good on their site

Yeh certainly is Paul , I buy pratical performance car and it was how I came across it as he has articles on it.
Mine was fitted via the tuner not at emerald and they did all the mapping. It was an early version of the ecu and not as complex as the beast they currently have which is top notch. I didn't have any real involvement in it apart from picking the ecu.
Sold it with the car unfortunately a couple of months later
He does one for the Golf MK2 1.8t conversions :mischeif:
I been meaning to speak to them to see if he can do one for the audi 20v turbo and what would be involved as i'm aware it would cost twice an MRC remap price but the flexibilty especially with my Avan'ts incar computer would allow tweaking on the fly
The one big advantage with Emerald is that you get Dave Walker himself to map your car. He will very rarely map other peoples systems. Most modern management systems are all much of a muchness, you need to check certain features; like do you want to run sequential spark firing etc. You should really look at the management the other way round ie: who are you going to get to map the car? Always fit the system that the mapper is most experienced and comfortable with to get the best results.
Home of the Emerald K6 aftermarket standalone ECU (Engine Control Unit) or EMS (Engine Management System)! Emerald K6 ECU is fully user manageable through our easy-to-use software. Plug & Play or Wire-Up engine management and tuning for professional car racing and hobbyists.
Note that their little 4WD roller only goes to 300 and some bhp - hardly adequate for the big power a modified S2 will easily produce.
I'd be keen enough to map it myself on their K3 system but for the price, it would be worthwhile having Dave do it once to establish a solid, reliable baseline for reference purposes - even if he has little experience on our engines - he really knows his stuff and as you say with the expert knowledge of his own environment would be able to get great results.
Actually if you remember back to Dave Walkers CCC days I seem to remember that the guy who developed the electronics side for him ran an Ur Quattro (Think it was a 20V)with the Emerald ECU so they should already have experience with the 5cyl
I was just about to send an Email actually - glad I checked here - let us know the outcome... If they have baseline maps for the 20V turbo engine then it makes it look all the more attractive - even on a stock K24 turbo.
I'm printing the manuals now - I can SO smell a project/blog on this coming along.
This discovery has made my day - couldn't come at a better time. Incredible how such a small world this is - I was reading DW's articles from the time I had my first car at the ripe age of 18.

If you have the time and patience you can realy do a lot with Megasquirt, but you have to do alot of reading and develop a good understanding of what you are undertaking.
If you have the money then chuck it Emeralds way, but for those wanting to develop a realy good understanding of fuel injection and how to map a car. Then Megasquirt with a wideband O2 sensor is the way forward.

It's a lonely path your walking with megasquirt on a 20v turbo. If I was after an ECU on a budget then VEMS would be the ECU of choice.
It will never ever be as good as the top end ECU's
I've only seen it used in budget fuel injection conversions which is about it's level of use.
**** - all that excitement for nothing maybe - I only see reference to a maximum of two coil packs... And it doesn't seem to support five sequentila injectors in the way I'd expect - maybe the 5th can be done as an auxiliary output. Dammit...
I assume that Jamo's old car that got the Emerald treatment was a 3B (single coil) and the injectors were 'batch fired' instead of sequential.
Honda CBR 1100XX Blackbird Turbo....undergoing major changes.....
S2 Coupe... bit easier off the line...
'03 ZX12-R daily hack.... lots of nice bolt ons...
