Chris Norman Posted April 2, 2019 Share Posted April 2, 2019 Currently have EU2 with distributor and single coil. Any benefits in moving to a wasted spark setup? ECU is early Emerald.Thank you Link to comment Share on other sites More sharing options...
rj Posted April 2, 2019 Share Posted April 2, 2019 Less moving parts Link to comment Share on other sites More sharing options...
CageyH Posted April 2, 2019 Share Posted April 2, 2019 And therefore less maintenance and less problems. Link to comment Share on other sites More sharing options...
Chris Norman Posted April 2, 2019 Author Share Posted April 2, 2019 Thanks, seems like a sensible way to go. From what I can see I need the two coils packs and two additional HT leads which sit in place of the current HT leads. Delete distributor and single coil. New coil packs then take signals from ECU.Other than any reconfiguration with the Emerald is it that straight forward?Advice gratefully received.Thank you*thumbup* Link to comment Share on other sites More sharing options...
elie boone Posted April 2, 2019 Share Posted April 2, 2019 You will need to change the spark plugs to NGK BCPR7ES as you convert to wasted spark. Link to comment Share on other sites More sharing options...
TomB Posted April 2, 2019 Share Posted April 2, 2019 I’d need more benefits to justify it to me. I think I’ve placed the dizzy cap & arm twice in 15 years. Any reliability problems have not been down to these components. Any other benefits? Link to comment Share on other sites More sharing options...
CageyH Posted April 2, 2019 Share Posted April 2, 2019 Chris, I fitted a GM coil pack when I did mine. Link to comment Share on other sites More sharing options...
rj Posted April 2, 2019 Share Posted April 2, 2019 I've seen something very neat with a Zetec coil pack.Or, of course, you can replace the cam cover with an EU3 cover and then use the EU3 coil packs. Link to comment Share on other sites More sharing options...
oilyhands Posted April 2, 2019 Share Posted April 2, 2019 The EU3 setup is much less pone to water ingress and consequent HT misfires as it has an all encompassing cover.You will need an extra coil driver wire from the Emerald to the second coil, the power can be bridged from the first coil.Just make the change to twin coil in the Emerald config file, the existing coil driver will fire 1/4 , the new driver wire will fire 2/3.OilyOiler Link to comment Share on other sites More sharing options...
djg Posted April 4, 2019 Share Posted April 4, 2019 Seeing as eu2 engines are getting scarce has anyone swapped a standard Ecu eu2 engine to eu3 engine and ecu setup? Is it simply remove engine, associated loom and ecu and then replace with an eu3 setup? Or is there a lot more to it.TIA Link to comment Share on other sites More sharing options...
revilla Posted April 4, 2019 Share Posted April 4, 2019 In principle is should be a straight swap as you describe, assuming that the EU3 engine is already in Caterham configuration (if it's and unmodified MG Rover engine you will have to do the usual conversions of grinding the block to fit the starter, installing a Ford spigot bearing and sleeve and swapping the water rail, sump, baffle and oil pickup across from your EU2 engine). All of the external pipe, cable and electrical connections should fit once you swap the engine loom. The main vehicle looms were identical and the same plugs were used between the engine and vehicle looms so it should be plug and play. You should also swap the MFRU (relay unit for the ECU) as EU3 and EU3 ones were slightly differently wired inside. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted April 4, 2019 Leadership Team Share Posted April 4, 2019 I assume something like the Mondeo coil pack would be fine, just a case of sourcing the original plug connector.Stu. Link to comment Share on other sites More sharing options...
oilyhands Posted April 4, 2019 Share Posted April 4, 2019 It will physically do the job, but be warned, they have a history of failure, I have replaced three in the last 2 years on Focus/Mondeo for friends.Oily Link to comment Share on other sites More sharing options...
TomB Posted April 4, 2019 Share Posted April 4, 2019 Still not clear 'why', aside from possible reliability issues with a dizzi, which Im not convinced by. Is there a fuel saving? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted April 4, 2019 Leadership Team Share Posted April 4, 2019 Dave, is the GM equivalent a better choice?Stu. Link to comment Share on other sites More sharing options...
CageyH Posted April 4, 2019 Share Posted April 4, 2019 My GM coil has been faultless for the last 10+ years. Link to comment Share on other sites More sharing options...
Mechanical Moz Posted April 4, 2019 Share Posted April 4, 2019 If using a remote coil pack & HT leads, rather than the EU3 coil on plug setup, why not use the EU2 VVC coil pack and leads? It bolts to the block under the inlet manifold. Link to comment Share on other sites More sharing options...
Chris Norman Posted April 4, 2019 Author Share Posted April 4, 2019 Thanks all this very helpful! Converting to EU3 requires replacement cam cover but a "stand alone" coil pack would work with the current cover, so I think I will look to a standalone coil pack (Dave - hear what you are saying about water ingress though).Question is which standalone coil pack?

revilla Posted April 4, 2019 Share Posted April 4, 2019 EU3 cam covers are available for £10-£15 on eBay. Link to comment Share on other sites More sharing options...
rj Posted April 4, 2019 Share Posted April 4, 2019 And I've never had the 400 gram heavy plastic cover on mine. No problems with water (there) in 13 odd years. Link to comment Share on other sites More sharing options...
oilyhands Posted April 4, 2019 Share Posted April 4, 2019 Given the alternatives the VVC block mounted coil is not a good solution as the leads are mega long and are prone to fouling on everything, a close coupled coil means shorter leads and fewer issues.Oily Link to comment Share on other sites More sharing options...
Chris Norman Posted April 5, 2019 Author Share Posted April 5, 2019 Thank you Revilla and Dave. So EU3 cam cover from ebay (!!) plus coil packs that fit in the cam cover - better packaging and will keep the water out.Excellent Link to comment Share on other sites More sharing options...
CageyH Posted April 6, 2019 Share Posted April 6, 2019 This is how I did mine.A GM coil made by Sagem - similar to the coil-4 sold by SBD on a home made coil bracket. Link to comment Share on other sites More sharing options...
