After market ECU's
Discussion
What you using, how did you find the installation. Would you recommend the one your using or wish you had tried another.
Its something I may do at the end of the year and really depend on how Johno gets on with his installation as would probably go the same route.( as he would be able to help me
)
I really like the idea of being able to plug my pc in and control everything and get rid of the AFM etc
Cheers

Dave Walkers book (Haynes) on engine management is a good read too.
Understandably biased toward the Emerald ECU, but very informative.
Also comes with a copy of the Emerald software(although not for the latest K3) , and it also has a software emulator so you can play a little.
You probably already know , but Dave also writes a column in PPC mag each month..

Agreed. I got it for Xmas, and enjoyed it a lot. Despite being a life-long petrol-head, I learned a lot, too.
BB - you live nearby, you're welcome to borrow the DW book. And I'm having an Omex 705 fitted to my Chim, so once that's done you can come and have a look at that, too.... Drop me a mail.
If I should go this route again I would go for the DTA S80PRO. It has everything you need inclusive a nice staff. www.dtafast.co.uk/

I'm at Oulton Park right now, so short post ....
I went Emerald and it will be the winter project.
Bearing in mind I found a cheap unused ECU and loom in the configuration I wanted it helped sway my decision.
So many of the systems I looked at gave far more functionality than I needed and were priced accordingly.
Additionally Dave Walker is only is very close to where we now live
so I can have him set it up....

This controls a wide band lambda and until the last 6 months was very expensive but is now available from £150~400 depending on what you buy and where from.
Take a look at :
www.zeitronix.com/index.html
This allows someting like Emerald to hit the idea of 14.7 mixure spot on .. and control closed loop very accurately .. so some fuel savings.

Before you choose an ecu you need to think about what you will want it to do?Dizzy,wasted spark or coil per plug ignition,bank fired,semi or fully sequential fuel injection?These are just the basics.You also need to think about how easy it will be to map,as even if you dont want to get involved it will affect your mapping costs if you go to a rolling road with an ecu thats a PITA to map.As for wide band lambdas,i personally would only recommend going to the expense if you intend to map yourself(great fun and very interesting).Some ecu manufacturers are not too keen on leaving one in a closed loop,and once you have had your cruise mapped for good economy,there is little point really as many cams and engine set ups like a much richer mixture in other parts of the map etc.

Doesnt the WB Lambda connect directly to the Emerald then?
Yes it does support WideBand. I dont think they supported seq injection or COP (seq was mooted IIRC) were the only limitations when I last looked at Emerald.

Like many ECus the emerald has a 0-5v input for a wideband controller to interface with, and a 0-1v narrowband input (not recommended unless you're a tightwad lol) .. there are detailed instructions for connecting the emerald k3 to the innovate LC1 wideband.

As I understand it, the innovate LC1 will screw into the existing lambda locations in the manifolds. should I run 2no. Wide band sensors with an aftermarket ECU - that is assuming they support 2no WB sensors?

The wideband sensors are physically a different size to the standard narrowband ones and you will need to get new bosses welded onto the exhaust.
There's no way you can call the silly narrow band things TVR/Land Rover used "standard". They were the Betamax of lambda sensors!
"Normal" narrowband and the Bosch wideband sensors use M18 holes. BTW if you want a well priced wideband gauge & sensor, you could do worse than looking at the wideband unit on www.vems.co.uk I helped Rob with some of the testing, and I was very impressed.
Ideally you should monitor both banks, but I got away with only monitoring one until I got the new firmware for controlling the 2 sensors with my ECU.
Based on the state my engine was in when I stripped it for the new cam, it didn't matter too much that I was using only one sensor for a year - both heads looked the same.

I cant see why 2 sensors make a difference really. If you run banked inj arguably, but would you want 8 for sequential, 4 for semi-seq would be practically impossible to plumb. Is there much difference between 1 monitoring 8 cylinders and 2x(1 monitoring 4) - I cant see it would give much more accuracy trimming cylinders.

2 sensors makes a difference (but only for individual cylinder trimming) if one sensor never sees gas from half of the engine. IE if you use the original fitting points in the exhaust.
And just to convince you that you really don't need 2 sensors in the standard placement: if you have 2 sensors and want to do individual cylinder trimming, then you need to know EXACTLY which cylinder was last to fire so you can identify which sensor you should take the reading from. This implies needing a cam sensor so you can sync up the whole engine. Just having the usual crank trigger isn't good enough for this as it leaves you with a choice of 2 cylinders that may or may not be on the same bank.
