Emerald K6 ECU
« on: June 13, 2010, 03:55:34 PM »

FedEx brought me an early birthday present today in the form of a new Emerald K6 ECU.
This is the latest iteration of the K3 which I had last time, but has some new features in the hardware (waiting to be activated by a software update)
Quote
It has been radically redesigned and has the latest generation powerPC processor, waterproof case and connectors, revised 1-channel/2-channel PWM, unipolar and bipolar stepper motor control, onboard Barometric pressure sensor, USB, serial and CAN interface and data storage memory, 6 ignition and 6 injector drivers. Some features will not be available straight away, but will be added as the software is completed. This can be done remotely by adding files to the software.


I got the flying lead loom and plug with the loom, as I was too cheap to spend £250-300 for a custom loom


The loom plug has already got many of the sensors wired in, all it needed was to insert the Wideband sensor wire, ignition feed and injector feeds, then label everything up, quite easy to do


I have a Techedge 2J1 wideband O2 sensor to integrate into the loom for active mapping


The ECU software version and config for those interested




Not sure whether to use a MAP sensor as well as the TPS built in atmospheric sensor and air sensor.  I know nothing about MAP sensors so not sure if I need to bother.

Got the initial loom planned out, pretty easy when you get stuck in, here is my variation (click on the picture to download the PDF)



Feel free to comment if you see any obvious flaws

Laid out and tried in the car to get the correct lengths, then a bit of heatshrink


The rest of the wiring and plugs will be sorted out after painting, as I am using grommets and not bulkhead connectors

Hi Biggles,

Very interesting topics about K3 & K6, mate. I must say that even if not located in the Arabian Gulf (France instead), I felt the need of joining you to exchange on these mapping topics. I'm currently planing to buy a K6 for my VX 20XE powered caterham running on throttle bodies.  I currently have an unsatisfying-not-user-mappable AlphaWeber ECU (so, already using a wideband lambda, but not sure which model it is, as the car is not currently @home) running poorly on the car.

First question about the loom : is the one shown on your above pics the "standard" option when ordering a new K6 ?
Second : do you reckon it is absolutely necessary to have a standalone lambda controller (this I do not have yet) ? (by the way, you link is corrupted, correct one is http://wbo2.com/2j/default.htm)

The Weber Alpha is a fine ECU if you have the correct map for your engine, to be honest any well mapped ECU will work.  The problem with the Weber is you cannot map it yourself, as they lock it.
I would be surprised if your Weber has a wideband, I think you will find it is a narrow band sensor, which is completely different and cannot be used for adaptive mapping on an Emerald.
I really like the Emerald, as with a wideband I can get a pretty decent map using it's adaptive mapping function.  Ideally the car should be set up on a Dyno and I plan to do this at some point, as with a decent (not me) mapper it can improve drive-ability hugely.
As to the wiring loom, I bought the Flying lead loom on ECU plug as a 60.00 GBP option, it can easily be adapted for any car.
