I understand that they have inbuilt ignitors in the coilpacks, and have the signal from the CAS to fire, BUT if you were to use the s1 loom using the EXTERNAL IGNITOR with the s1 coils, will I be able to do this? I can sell the coilpacks, but I'm I want to see if it can be done, the coils are less than 2000km old, it's cheaper If I can go this way and to be honest in my opinion integrated ignitors on coilpacks is a more un reliable set up as it's introducing further heat to a area which is prone to cracking ect ect, it's not so much about $$ but more so using what I have and reliability

the connection wont fit. but if you get the ignitor loom, and coil loom you can cut and wire it in manually. a good tuner electrician should be able to do this without any issues.

but you are better off trying to find someone who would be keen to swap the s1 coils for a s2 set.

by the time you wire it all up its going to be better to just sell the coil packs and buy a proper series 2 set.

Cheers guys, I'm not to bad with electrical, I just wasn't sure if the ecu wouldn't read it or if it was throwing out different voltages ect ect, so in saying that I should be able to do it,

Thanks alot, appreciate the help

The ECU sends the same signals out regardless of which coils/igniters are at the other end of the loom. It's just that the wires run direct from the ECU to the coils in the S2 case and have to stop off at the igniter in the S1 case. In the same way, the various igniters don't much care which ECU is telling them to fire, and they also don't much care which coil they're then firing (assuming separate coil and igniter), unless the coil also has an igniter, which is not so good.

      Hi Yes we're a bit optimistic we might get something out of sealing up the two pipes of the external wastegate and reactivating the stock one. I believe the orginal stock wastegate was tack welded shut. It doesn't budge and visually looks closed and sealed. The car has noticeably more lag so it could be at least part of the problem, maybe all. It's definately one of the key changes made since last tune. And it's one that's more difficult to fully understand and measure, not like for instance timing or cylinder compression.  Thanks for that feedback, we'll let you know how this progresses. Fingers crossed.   Regards Rob

      Well, I was going to say, "Is the wastegate set up so that it is not leaking?" That's actually a different thing to what you're asking about. In theory, if you have allowed the two halves of the manifold to commmunicate (more than the stock manifold does - which is at least a little bit) then the negative effect should be apparent in delayed spool, not in outrigth power. OK, maybe just maybe, a badly set up twin scroll wastegate "crosstalk" might kill the top end, although it's hard to see how. What is happening with the original wastegate in the turbo? is it sealed off properly. If it's left flapping in the breeze, it will f**k everything up. If it is still there, and can be returned to service, I'd be capping off the external (presuming the two halves can and will be isolated from each other after doing so) and have a go with just the stock wastegate. I have an internal wastegate in my highflowed rear housing. The bigger opening and flapper should be fine to >250 rwkW. So there's not exactly a pressing reason to have the external. Done right, an external will give better results. Done wrong, it might just be possible to have worse results. Report back!

      Hi Rob It's a nistune ecu. Yes same shop, good reputation. Apparently the computer on the dyno is compensated for temperature.    Chris was saying that the lean or richness of the mixture would be covered in the actual tune, but he's already picking up in advance that it's under what it should be. Regards the dyno, it's also noticeable on the road. But I just want to add something that has just come in, it appears there might be something in the setup of the external wastegate. In the exhaust manifold there is a centre divider between the front three and rear three cylinders. The external wastegate has a pipe from each side that join at the wastegate. Theory is those two pipes just might be pypassing that divider and introducing a problem somehow. Is anyone familiar with the divider in the exhaust manifold and the effects if the two wastegate pipes were to create a bypass path? Thanks for your questions Rob, interested in your thoughts on this external wastegate bypass theory. Regards Rob
