hotpantslovebug Posted February 19, 2014 Report Share Posted February 19, 2014 Have you looked into a new pair of OEM plugs, not platinum? Seen them around for 30 a set which is expensive but they have yet to give me problems even 30k later. Also I know a lot of guys with bigger turbos have gone to the MSD6 box, usually 150ish on ebay. That could help support the power you're putting down, only down side is car/rotor/plug life. 1 Quote Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted February 19, 2014 Author Report Share Posted February 19, 2014 I was hoping that my friend was going to bring some OEM turbo coppers, so when he didn't I just went with the NGKs. They're a temp range colder than OEM, I'm going to stick with them. I do want to be able to open the gap to .032 for idle quality, so I need to get more spark power. I'd rather get a kenne-belle boost a spark than the 6AL. Hopefully I'll be switching to ID HD coil packs. :ph43er: Quote Link to comment Share on other sites More sharing options...
fwdGTP Posted February 19, 2014 Report Share Posted February 19, 2014 iirc I'm running bkr6eix Iridium plugs at ~.025 gap. I haven't gotten any misfires since gapping them down, but at higher gaps I was misfiring on my old turbo setup. Surprisingly no misses all the way up to 32psi.

lookforjoe Posted February 19, 2014 Report Share Posted February 19, 2014 The correct Bosch plug is a finewire double platinum 0 242 235 749 Quote Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted February 19, 2014 Author Report Share Posted February 19, 2014 (edited) I'd rather have a well performing copper plug that needs to be replaced every 30K than a platinum that lasts for 100K. Platinum doesn't conduct as well as copper. Granted it can withstand higher temperatures so you can have a smaller spark tip. However, I don't think the greater charge density from a smaller tip fully offsets the difference in conductivity.

lookforjoe Posted February 20, 2014 Report Share Posted February 20, 2014 No way these will last 100k, nor will regular coppers last 30k. These have a 30k service interval, and they do last that long, even on my setup. You can't expect regular plugs to last more than 10-15k, if you're lucky. Edit: the IPD HD coils don't play well with M 4.4 + COP. Unless you are matching / replicating the control system as implemented in ME7, you'd do better to just get Bosch Motorsport Coils Quote Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted February 20, 2014 Author Report Share Posted February 20, 2014 (edited) Maybe my service lifes' were exaggerated, but it makes the point that I care less about longevity than performance. I appreciate you input on HD coils and M4.4, but my COP setup will be different from your add-on board. What were your problems? Was it related to dwell time?

lookforjoe Posted February 20, 2014 Report Share Posted February 20, 2014 The IPD coils have some additional circuitry that doesn't play well with the non-stock COP. All the coilpacks cracked & failed within a few months of use. Once they cool off they come back to life, which made it a PITA to diagnose.

NitroX5 Posted February 20, 2014 Report Share Posted February 20, 2014 +1, problem is the dwell time. I run them 2.0-2.1 ms, this value floating around these coils when we speak about EMS. Would be great if you coluld ask the M4.4 COP developer, what did he implement. Quote Link to comment Share on other sites More sharing options...
Johann Posted February 20, 2014 Report Share Posted February 20, 2014 Could even be 1.8 to 2 ms. M4.4 probably is giving them 3 ms while the COP board changes nothing. . Quote Link to comment Share on other sites More sharing options...
NitroX5 Posted February 20, 2014 Report Share Posted February 20, 2014 (edited) More dwell time increase load on coils (charging time), just to make it clear to everyone. So shorten the time is safer. 3ms is too much IMO. Edited February 20, 2014 by NitroX5 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted February 20, 2014 Report Share Posted February 20, 2014 The COP components were made by JG Ignition (in Sweden?) and packaged by TTusb for use with M4.x. I doubt they did anything other than package the hardware. Quote Link to comment Share on other sites More sharing options...
NEU Posted February 20, 2014 Report Share Posted February 20, 2014 I'd rather have a well performing copper plug that needs to be replaced every 30K than a platinum that lasts for 100K. Platinum doesn't conduct as well as copper. Granted it can withstand higher temperatures so you can have a smaller spark tip. However, I don't think the greater charge density from a smaller tip fully offsets the difference in conductivity. You could try Bosch Super Plus, they are copper/irudium. I've been running them for several years with the IPD HD COP coils and mine last about 60K. And at relitively big gaps too, .035". At 60K the corners are round off slightly. And they are cheap too, only like $2 each. On another car I had with MSD 6 and high output coil/ignition module I used to burn thru the older copper Super Plus every 10K. Leaving them completely rounded off at the corners. Bosch Platinum weren't any better, the electrode would completely melt away. Quote Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted February 20, 2014 Author Report Share Posted February 20, 2014 Could even be 1.8 to 2 ms. M4.4 probably is giving them 3 ms while the COP board changes nothing. . Does this hold true for normal ME7 coils? If so I'll reduce the dwell time. Quote Link to comment Share on other sites More sharing options...
NitroX5 Posted February 20, 2014 Report Share Posted February 20, 2014 ME7 coils are all the same as I saw.Quote from Karl Buchka (he is running VEMS) "Coils are OE Volvo from an S80 T6. They have built-in power stages and are suspected to be internally identical to the Bosch Motorsport Single Fire PT coils, data-sheet here:http://www.vems.hu/files/MembersPage/KarlBuchka/Single_PT.zip " According to this, the safer dwell time is 1.9ms at 14V ---> 2.4ms is around the edge. Volvo use BIP373 built in power stage, this is why the sheet should be suitable. Quote Link to comment Share on other sites More sharing options...
