Boost Junky 1 Report post Posted June 30, 2009 (edited) do a skid with those massive feet you got it sitting on! any thoughts on what you gona do for the guards? Nice work Luke Looking forward to a vid (skid) Lol shes due another descent skid! Will have to wait till the next skid day out at the local skid pad Yea ive priced up a guy to cut and weld new guards which has been discussed in my wheels thread dude. Cheers Simon, I should have a boost video of it tonight hopefully. By the way, does anybody know what drives the individual coil packs on each cylinder? Do they have built in ignitors? or are they located somewhere else? I was reading through the link ECU manual last night and it states that Link G3 LEM only supports 6cyl ignition systems with coil packs via wasted spark. It has to ignitor outputs in its loom so you have to run two ignitors per 3 coil packs.. Cheers, Luke Edited June 30, 2009 by Boost Junky Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted June 30, 2009 (edited) I just had a quick look online - there is a possibility you will need 6 igniters wired in pairs to the Link (so wasted spark). I am NOT confident about this - I suggest you contact Link directly or try their forum. this is not an easy one. For 6 cylinders you will need 3 ignition channels for wasted spark.

Ive been reading the link ECU Manual and it only has 2 ignition outputs so that means you can only run two ignitors.. these in turn are capable of running from what I believe 4 individual coil packs (so support of upto 8cyl). So im thinking I have to run 3 coil packs off one ignitor and 3 of the other. Also spoke to my tuner this arvo and he said he will have to look but is sure im going to need two ignitors to run them.

Mike 1 Report post Posted July 1, 2009 (edited) I'd agree with camB here, I would be very surprised if link didn't have 4 ignition channels, that way they could drive 2 ignitors each for 8 cyl wasted spark. I'm 99% sure M50 do not have built in drivers. In your case you need 3 ignition channels for your 6 cyl wasted spark EDIT: see here: http://www.linkecu.com/products/pdfs/lemg3specs 4 ignition drives for 8 cyl wasted spark so you use 3 drives, and wire each drive to 2 x ignitors which will in turn run a coil each Edited July 1, 2009 by Mike Quote Share this post Link to post Share on other sites

CamB 48 Report post Posted July 1, 2009 (edited) so you use 3 drives, and wire each drive to 2 x ignitors which will in turn run a coil each I wonder if it would be less work/cost to get a set of Mitsi 6 cylinder wasted spark coils and the 3 channel igniter ---> from a v6 GDi I think. Would cost bugger all (I got the 4 cylinder equivalent from pickapart - dual channel igniter and coils - for $34). Or 2x the 3 channel igniters with the BMW coils - basically just looking to cut costs. Its this thing: "Mitsi J723 ignitor module". mops used it on his car: Edited July 1, 2009 by CamB Quote Share this post Link to post Share on other sites
Mike 1 Report post Posted July 2, 2009 I'd be inclined to use the M50 coils because he has them already, and it will be a much tidier install because they're meant to be there. Getting the mitsi ignitors could be an option though. I'm not sure how many coils you can run off each ignitor, I guess if they're were designed for it you would only need three ignitors. Luke, you said its been running already, is this on standard ecu? If its on the link then how has it been setup? Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted July 2, 2009 Am pretty sure the Mitsi igniter has 3 channels of input / output, so only 2x would be needed? Either way, I agree on using the BMW coils purely because it would be tidy. Quote Share this post Link to post Share on other sites
Boost Junky 1 Report post Posted July 2, 2009 Yea im going to stick with the stock BMW coil packs going onto each spark plug. My mistake you guys were right there are 4 ignition outputs (drives) on the G3. So as you stated Mike I will need 3 ignitors, each of these ignotors will drive 2 coil packs?

Hmm, You may wanna check it. I thought 1 igniter runs 1 coil, any more coils and you will need to add more igniters. So you would need another 2. Don't quote me on that , megasquirt could be entirely different. I have just finished wasted spark setup on my project, Just need connectors to plug into the coils and spark plug leads for the GM twin post coils. I used an 8 igniter coil driver, So I have plenty of spares if i burnout any of them lol. Just needed 3 igniters to use 3 twinpost coils, so 1 per coil.

CamB 48 Report post Posted July 2, 2009 Luke, you have single coils, so you need an igniter per coil OR you need 3x 2 channel igniters OR 2x 3 channel igniters. How you wire them would depend on what you get. Quote Share this post Link to post Share on other sites

How you wire them would depend on what you get. Correct Cam either 2x3 channel or 3x2 channel ignitors. Ross my tuner said I may not need anything yet. People she is going in to get wired up and tuned on Monday FINALLY! I will keep you all posted on the progress Quote Share this post Link to post Share on other sites
Boost Junky 1 Report post Posted July 10, 2009 So tonight I spent a descent 6 hours after work on the beast performing my final tweaks and fixes as she is off to the tuners for a week on Monday Welded up a quick screamer pipe to direct my exhaust gases away from the firewall last night and wrapped it tonight. Put a brand new fuel filter in and added some penrite SIN race coolant to my radiator, which helps LOTS with cooling the motor as it has no glycol. Fixed up some melted wiring on the passangers footwell which Dad melted when we were fixing the firewall from the other side woops I also put all the carpet back to normal and dusted the damn engine bay removed all loose bolts and rubbish haha so shes all ready to go! Heres some more boring pics as you can see little has changed since last time except the wastegate pipe.. cheers guys! Quote Share this post Link to post Share on other sites

Boost Junky 1 Report post Posted July 10, 2009 Thanks guys! Yea looks way nicer now with everything tidied up. Just drove it 13km out to my friends house she works at the dyno tuners shes taking it to her work for me monday morning. Need to do something about the plastic rocker cover.. the wastegate pipe melted a section of it right where it comes against it, even with it heat wrapped...

Yea im probably going to direct some air up to that region and like Marty says to make a heat shield up either out of ali or heat sheets I can get from my gasket suppliers at work. WEAPON LOL Ollie! I would probably make use for one of those if I had kept telly of how much i spent Cheers for the comments Edited July 13, 2009 by Boost Junky Quote Share this post Link to post Share on other sites
