So i've been seeing people saying that SAFC will fixc the coil pack problem. Is this correct? If so, Power FC will do the same but more right?

If the sparks are leaking out of your HT ignition cct it is only going to get worse. Coilpaks & all types of insulation for that matter, age & eventually develop miniscule cracks (leakage paths) sparks burn, make/follow carbon tracks, line of least electrical resistance. Answer = Splitfire or in any event replace offending coilpaks with known good items.

no, niether is at all true. search.

arcing of the coil packs is due tothe resistence inthe electrical path being greater than an alternative route for the charge to escape from ..so the "spark" side steps the plug and either wholey or partially earths onthe engine head. this results in a weak spark at the plug and thus missfires. when hot (eg under load at high revs and when engine up to temp) this resistance increases so therefore the missfire ets worse.

as the other guys have said only option is to repair the brake in the circut. this can only be done by replacing the coilpack with known good ones.

as this aint cheap first check youre running correct plugs and that the afm is ok and air filter clean ...(carb cleaner)

im buying spitfires next week. as my coilpacks just died.

siliconing the coil packs can't fix them then?

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
