Just would like to know if ppl still using spiltfire coil packs or what is better?

I started to get miss after 7krpm install a hks twin power (helped) then the miss came back after a few weeks, does it all time same

Rpm range. New plugs fitted and gapped to .8 and spiltfire coils about 6 yrs old and about 30,000kms on them. All brand new engine harnesses...also boost is about 22-23psi

E85 or?

What plugs and heat range are you running?

Was it OK for a while and just started or has it been happing from the start?

Have you checked the Spitfires for arcing?

Is it missing when hot?

use copper plugs at 8 heat range from memory, Check coils, make sure your alternator is pumping out decent amperage, flog hks twin spark off and buy Morris tech igniter

Ditch that pos pretty gold HKS box.

For those of us that missed the bulletin what is wrong with the HKS DLI II ?

That hunk of junk cost me two sets of coils. Ditched it along with the factory and used the above mentioned ignitor and issues disappeared.

The factory ignitor is an electrical bottle neck.

That and it's more expansive and harder to get then the Morris tech ignitor

Paul's making 480rwkw with no more then spitfires and a Morris tec ignitor.. I'd be right in assuming that the plugs are copper, heat range 8 gapped at .8 (I may have put the last set in?)

This business of reducing the gap of the plug down to nothing and reducing spark size is a bandaid fix and simply ridiculous

I can't tell you how but I had a new set of OEM and a set of split fires both kick the bucket within 3-4k kms. Ditch the lot and it's all good.

Joey had issues at 400 rwkw, put the ignitor on and done.

I've sent a few of these around the country and on every car the ignition issues disappeared.

I know of at least 8 GTRs with 500awkw+

3 GTRs with over 600awkw

3 GTSTs with over 500rwkw

All with Splitfires and NGK copper plugs. Plug gap is critical and all plugs must be spot. The difference between a .6 and a .65 gap is noticeable when you start going cranking the boost.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
