Been reading some threads that this would come to weber ecu? havent seen any yet.

 

Coilpack (wasted spark) is a common conversion on the L8.
Ive not personally seen Coil on plug done as a conversion yet on a YB but I believe that RP labs have done so on lancias so it should be ok on a YB too.

 

Ok but rp lab is the whole package right whit a complete modifyed ecu etc and pretty expensive.I thought someone would have worked something out whit 4 sep coils by now to weber marelli,and advanced version of wasted spark.

 

The RP labs is a chopped up and altered L8.

The way that the MSD coilpack conversion works, could also be done for individual coils instead fairly easily, drop Flux Capacitor a PM to ask if he is developing anything for them along those lines as I dont know if they are or not.

 

Pretty sure RP labs have done so on cossie L8's, coil on plug that is, at least one of them, as me mate ran it on his mk2 rs2000.

But then it still would be wasted spark and u would need 4 amps and all what that brings right?

 

I'm sure I recall Stu mentioning this as a potential development for 2010, defo read someone was doing it on here anyway. As chip has said, i imagine if it's available for Lancia (which utilises Weber Marelli management also) it should be adaptable to cossie.

 

Not if the board handling it had 4 seperate outputs, although I suspect you would start running out of pins in the normal harness, so might need to be done externally.

If it wasnt for concerns over heat you could of course run it on the normal W/S setup MSD do, but that wasnt what I was suggesting, I was suggesting it should be possible to develop a similar setup but that uses 4 trigger wires not two and runs non wasted spark.

 

That would be nice but i havent heard anything about it.I hope they can get 4 wires out of the ecu or a extern unit which can.

 

Its possible im sure, the question is if enough people want to do so on these old ecu's to make it financially viable to do so.

 

Yes thats the problem.But to runt 4 coils now whit wasted spark u would need coils that support/need amps,u need 4 amps and all the wiring to them and the coils=not worth it i think and its still wasted spark.I would easily fit a trigger to my cam but as u say someone need to divide the ign signal from ecu to 4 and know when the ign secuence starts by a trigger or something so u cn get 1-4 cyl ign pulses.

 

Yeah you need to use the phase sensor for it like you use it for sequential injection.

 

I can only hope that someone makes this work soon,because the 400 pounds of wasted spark kit is not far from an aftermarket ecu whit cdi/dis ign.

 

Can't you just use vag coils? pretty shure they've got amps built in them. might be wrong though..

 

Nope that wont work att all they will fried BUT i spoke to a friend today and as soon as the snow disapears im going to get direct fire whit vag coils and weber ecu they have a system all ready to be fitted and tested on my car,very complicated system that i dont understand shit about but it involves a little cpu etc and a small casing to be used.
