Another Emerald Q... (and more to come)

[Pupp]

Maybe we need a dedicated area

Anyone know whether there is any possible functional benefit to using a wideband sensor (with the obvious advantages of this), whilst retaining the existing narrowband jobs in situ? Looks like the Unit can handle a narrowband input when configured appropriately but can it do that as well as use the wideband, perhaps on different maps (if the facility is there, might as well use it and it might be interesting to have an emulation of the existing set up as a fall back)...

Alternatively, anyone know a source for suitable bungs for the manifolds to blank off the narrowband ports if they are completely redundant?

You could just leave the old lamdas in even if you dont use them its not going to cause a problem

I would say the narrowband lot will be redundant once you have the wideband sensor in. The narrowband can only tell the ECU if its below, above or at lambda whereas the wideband can give a pretty accurate O2 reading to allow fueling adjustments in real time. So you can either leave the narrowband sensors in place as Graham said as they won't affect the running, or you can remove them and just get some boss bungs of the same size (like the wideband bung you got with the kit).

If you have a wideband sensor and the ECU can accept that input, then it would be sensible to use it; the narrowband sensor is far less useful and basically redundant once you have the wideband sensor. You could just leave the sensors in to block the holes, but remember that they will be knackered fairly quickly if they're left unpowered so don't be tempted to try them again later.

Indeed.
And they are titania - which doesn't output a 0-1v signal, so your emerald is not likely to support them. Either leave them powered if you ever want to reuse them or remove and plug the hole with a stainless m12x1.25 bolt from namrick.

yup, the emerald canot read the std lambdas anyway .. ive tried many times to make it work but it just wont. But once you have an accurate wideband in there then there's no need anyway. If youre on an innovate just remember to keep it calibrated, it's all in the instructions.

[Pupp]

Ok, cheers, decision made then... if they're not going to be functional there's no way I'm giving them bay room but was happy to keep them if they could serve any purpose.

Now, next Q.... coilpacks. Don't want to use Rover, don't want Ford, didn't someone say Citroen/Peugeot had something suitable? Anyone know the donor details/part nos please?

1996 Citreon Xantia will do the job, but its fitted to loads of peugots, citreons etc etc

There's no real advantage of these over any of the others performance wise ( used ford jobs on my wedge) but the do have std plug lead ends so you can re-use some of your existing plug leads ( some will be too short)

Thanks Matt, that was precisely the thinking... ease of sourcing replacement leads as I understood the ends were conventional.

I'm using ford coil packs. These people will make up leads to your specification:

They are spiral construction. If you feel that magnecor leads will somehow transmit that spark better, than they [magnecor] will relieve you twice as much money and make a set for edis coil packs too - personally I cant see the point - coil packs produce a decent spark without wasting a fortune on fancy leads.
