Emerald is about to launch the K6 ecu, with a host of improvements, two of which can also be put onto the previous K3 version, they are TRACTION CONTROL and LAUNCH CONTROL.
NB the new K6 uses the K3 software up until release date proper when a simple download from emerald is needed to update the lot, this will be at the same time as the K3 LC and TC are launched.
The new K6 uses totally different software, connectors and has many more features than the K3, personally I'd be well happy with LC on a 2wd cos!!
I cannot give any further info on the K6, but there is a small amount of info on the site www.emeraldm3d.com

Can the new software also be used to map the older ECU's?
(sounds like they are compatible in that respect if the old software will map the new one) obviously minus any new features working of course.

This is the one update that you just know HAS to be an improvement as the current mapping software by emerald is by far the worst in the business and despite years of experience myself as a software engineer myself I can think of NO way in which it could possibly be made worse, so by definition the new stuff just MUST be a massive imrpovement if its different, as it couldnt possibly be worse!

 

Already discussed upgrading mine for this.

 

Even with the present/previous K3, it was hard keeping up with demand, so must have been doing something right.
No the older K3 cannot be upgraded to the complete K6 version, for various reasons I don't understand, but nice to see the new improvements to the K3 coming on line also, shows they're commited to all users past and present, old and new sort of thing.
Biggest selling point for me is the attitude of the staff, nothing is too much trouble, always happy to go way out of thier way to help where they can, some of the "finished" ready to be mapped cars are a long way short of this, but all sorted out effeciently by dedicated staff who don't just see a £ sign, when they see a customers order, many agents around the country also.

Its a shame the customer service has never extended to actually bothering to write some decent software for the customers to use.

You really should be paying trade fees if you are advertising quite this directly though, Ive read actual adverts that come across as more impartial than your "opinion"

 

Really, about the advertising I mean ?, I'm not a trader and have no financial interest in the product whatsoever though, just trying to help out, sorry.
tabetha

 

Lol, no mate. You can say what you want as it's not your company as far as I'm aware.

 

Seems really good value for money, do you get everything you need with the kit and who maps these kits ????

 

Most established tuners will have been subjected to having to map emerald at some point, so you can take your pick really with mapping.
Best bet is to go to dave walker who makes them though.

And PLEASE not to me, i fucking hate them and yet seem to end up mapping loads of them

 

Yes you get everything needed in the kit, ie ecu/software/lead, many people all around the country who map these, very easy to do, I go to Emerald as I live about 1/4 mile away, but would have gone no matter what the distance.
It's a 36-1 or 60-2 trigger pattern that is normally used, two most common, but does accept many others, uses all the std sensors, or other ie aftermarket, my tps is a universal one, but it's 2 mins on the computer/laptop to "align tps" job jobbed, does inverted tps also.
I used a 5 1/4" trigger wheel from www.trigger-wheels.com, then machined off the lugs on my pulley and used a cast rod to weld trigger wheel to pulley, tolerance is +/- 35 degrees of true tdc, so could do it blindfolded nearly and still be close enough.
The K3 does not exist anymore as far as new sales go, it will be a K6, so ready for all the new features to come online, and will be a big improvement in certain ways over the K3, but as said K3 can add LC and TC.

Cheers Tab & Chip

Sounds great for the money it's something i will really think about over the winter.

 

I can also put you onto someone for a new loom if needed at a VERY good price.
tabetha

 

I have a new loom made by Ryan.

So the only other thing you need to buy is a trigger wheel???

 

Chip.. My FRS needs its emerald ecru mapping please.......

have you mapped emerald on a RR? As it did seem very easy when I did it/watched it being done... On the road, yes I agree it is a total slag. Lol

 

Yes about £20 from memory, unless you want to go coilpack ?, in which case leads/coilpack, depends on your loom ?
You can ditch the ignition amps as they are internal, but if needed can run on the old dizzy/coil set up no problem.
Obviously however you had your loom made will dictate what your able to use.
tabetha

 

Tabetha,

Do you know if it will run wasted spark on a V8 OK ?

Mark

 

Tab I run wasted spark already so have the leads, coil etc so does the loom plug straight in to the ecu or does it have to be modified ?

 

Your loom will NOT plug into a K6, a patch lead can be made to enable this, with the ecu you get the K6 fitting for the end of the loom to fit into the ecu, so can always "replug" your loom with the supplied connector, you also get the software disc that cna be used on lappy etc, and lead.
The coilpack will not be an issue, at time of ordering discuss what you want, emerald will NOT send out any ecu without a base map, the closest one they have to your spec, just mention it is on coilpack, using 36-1(which is 90degrees btdc +/- 35 degrees), though you can adjust settings yourself, eg tps alignment takes a few seconds when installing no measuring no nothing, just press pedal fully click ok on laptop!!

have spoken to dave walker this morning and he has confirmed the new software when released will be able to map the k3 ecu's

 

Hi Mark,
Yes no problem, the K6 can run coilpack V8, as could the K3.
tabetha

 

I have only mapped them on RR and personally found it a breeze, very easy to get round and quick to arrive at where you want to be. To be fair it's always been on race cars (NA and Turbo) so not needed to worry too much about the pleasantries of super clean driveability under all conditions.
So far as customer service and support is concerned you will go a long long way to find better.
We recently found ourselves with an ECU failure (long story, not their fault), it broke whilst testing late on a Thursday afternoon, a phonecall later and someone despatched to Norwich for the day with ECU in hand, saw it repaired tested and back on the car by end of Friday evening ready for Sunday race. They made no promises, as obviously they weren't to know what they would find when they got it apart, but were willing to try their best in what were frankly unreasonable timescales to most industries.
Top marks to Dave and the guys, that goes an aweful long way to keeping and making customers IMO.

 

Im rather glad i havent bought a k3 yet, didnt even know there was new version coming!

If i purchase from this point onwards, is it full k6?

Need some quick answers too if anyone can help. Does sequential injection require 4 cables from ecu to injectors, and 4 back again or just to earth? And what sort of current will the ECU draw?

I'm putting into mfi car so no wiring to speak of under bonnet really, does the ecu require constant 12v and ignition 12v too or just ignition?

 

sequential inj. requires 4 wires (one for each injector drive) from the ECU and one 12V supply common to all injectors.
K3 will draw little current in it's own right approx. 0.2A from memory, The ground return connection from the ECU will see considerably more when running due to switching of injectors. coils, valves etc.
K3 only needs ignition switched supply

 

Cheers mate. I take it the live for injectors comes from ecu to make it ignition controlled instead of permanent?

First project and I'm jumping in to the deep end

 

The tidiest way is to have a relay to switch the 12V supply to the engine system (ie ECU on pin28, injectors, coils, valves etc.) and controlled by the ECU Pin4 (Main Relay control pin).
Take an ignition switched 12V signal to ECU Pin11 - when this is active the ECU will then switch the main relay on and supply 12V power to the whole system.

Read the Emerald maunual - http://www.jkm.org.uk/performance/Mi...aft%20v051.pdf - that will answer a lot of questions.

 

Cheers I'll print it off and study it.

Undecided between emerald and dta s40. They both seem so similar!

 

looks like they have finally spent some more money with GEMS then

 

On a set of rollers its much easier than on the road, although TBH its still a bit of a ballache the number of keypresses you have to enter to make each change compared to much more sophisticated mapping software like autronic or motec or megasquirt etc which have been far better written, so can still be mapped quicker than emerald IME, and that applies to both on the road and on the rollers.

 

Have you got an Emerald ECU on your car Tabetha, I seem to remeber you had a non Weber one, if so was it hard to change over?

Hi Tab,
spoke before about K3/6 Friends car all ready now for new season Tarmac, The k6 was fairly easy to fit as i read up on the installation very thoroughly, The car came with several base maps, and we used the one nearest to our speck engine except different cam's, the car ran on 1st attempt trimmed the fuelling as it warmed up to a very stable idle of approx 1150 rpm, the engine is a mi16, on throttle bodies, 6,speed box uprated drive shaft's The car is a pug 106 with a lot of works parts carbon fibre x pack type body kit,
We will be resetting the throttle pot and taking the car out a week Sunday,
There is a flat spot where the torque comes in approx 3500 rpm, The lambda kit we fitted works a treat and a must for mapping, on the road i think it will be difficult to hold any load points ,, so will block the map in the area where the flat spot is and adjust and see, we have 3,maps saved, and will also try the adaptive mapping,

Cool car, got a build thread?

 

Out of interest why was tabetha banned ? He posted lot of interesting things over here

 

Yea id like to know that aswell the guy is very knowledgeable & informative

 

iirc it was because he told a moderator in no uncertain terms what he thought of said person. But that's what I remember so could be proved wrong.

 

Hi Chip,
My mate's car he's built a few rally cars from shells up, this one took some fitting to get the engine and box in, when i go up there next week, i'll get some pic's
