Considering an ECU upgrade for the beast on the basis that the original one doesn't have the resolution to accuratly control the engine comapared with modern electronics.
I have for a time been looking at the Emerald ECU as a viable option, but thought I would ask your opinions before I go down that route.
I note that the K6 they sell only has 6 injector and 6 spark outputs which would sugest that there would still be a degree of waste per revolution?
Against this what other options would I have?
Any thoughts appreciated.

They do a special for the V8 Cerbera with 8 injector and 8 ignition drivers. I have one on mine and it works just fine. The power increases are not huge but the multiple map facility is useful as I can turn down the bangs and pops in town. One downside is that it does not have dual wideband lambda support so you can't trim each bank independently. There are other ECUs which can do this but the price goes up (a lot).
sounds handy, so with the 8 ignition drivers, is it them worth going coil over or along those lines? Do you still run wasted spark?
Not expecting huge gains, but refinement and the map ability was the thought, having the ability to have a power, town and then an MOT map could eb somewhat useful

any modifications to the engine ? if not save your bucks and get a regular remap.....I have for a time been looking at the Emerald ECU as a viable option, but thought I would ask your opinions before I go down that route.

4 injector drivers for coils and injectors. Run the ign wasted spark as normal, run the injectors in semi sequential ie 4 pairs of injectors (means you don't need a cam sensor either). If you want to go full sequential (8 injector drivers) that's waaay more expense.
I've been in contact with karl at emerald recently to add to the list of people asking for twin lambda trim tables and that's now coming in the new update in a few weeks, so if you can hang on till then you can benefit from that.
All k6 ecus will be upgradeable to that spec so existing cerb emerald owners on later ecus can have that, as well as all the later ecus on chims/griffs etc.
If you need any more info pm me.
Ps the original mbe ecu is also very good though!

When you say remap, do you mean the chip replacement, or the ecu as a whole, as I had a chip some years ago.
Besides, not sure I would be totally happy with it. I know we are getting in to diminished returns territory.
There will be port work, and raised compression too, possibly considering a 4.7 but don't know...
Also, must point out that cerdad is my dad, just swapped computers....

in that case of course you would benefit of a new ecu. either semi or fully sequential will do the job.Besides, not sure I would be totally happy with it. I know we are getting in to diminished returns territory.

twin wideband lambda and knock control would be a nice feature too.
in mind i would have emerald canems mbe and i guess all in the region of around 3K plus pounds fully fitted.
I used an Adaptronic 420c ECU for supercharging my MX5. The next one up supports sequential ignition for 8 cylinders and dual wideband O2 inputs too:

Haven't thought of what else you may need to modify on the engine to add that, but may be worth considering.

If you can get your hands on a copy of the TVRCC's Sprint magazine 468 (Dec 2014) then Dave Parkes ran an article oabout fitting the 'latest' MBE ( 9A9B I think ) to his 4.5. 
Yes I spotted that, I think he had a non remapped MBE so was comparing against that. I was wandering how a good remap on a standard MBE stacks up against different ECUs for a basically standard engine. Sounds like its not really worth it, unless you want the multiple maps or traction / launch control. I can see the point of multiple maps....I do remember reading that article actually, pretty certain I would still have it somewhere.
I know its a lot of money, and like all things it is diminished returns. But I just want to. Being worth it is not the problem but more the challenge of integration and change to the vehicle that I would like. Its different, and would stand out, well not really but you know what I mean!

I've had a deeper look into the Adaptronic e1280s ECU and whilst it would be capable of managing the AJP with dual lambdas and TPSs etc it would not do so off the shelf. There are a couple of options to enable support but after looking at the configuration software it looks a big job and would require extensive changes to the logic setup, essentially rewriting it to support the AJP. Might be worth it for some applications such as FI, but certainly not for the light hearted.
