Anything from stock to ultimate ignition setups!

Post what you're running and whats working for you..

I've not seen where even at 250+ whp (GE or GD) that the stock ignition was not up to it.

Plug gaps closed down (.025-028") is about the most we've had to do, and that was expected for a boosted application.

 

Best spark plugs for N/a or boost setups then

Ive used the denso Ik22's with the Kraftwerks S/c worked great

 

I'm on the IK22s NA and pretty much stock otherwise at the moment.. still picked up some short knock events on my testing with Meijer's 93 E10 on my commute that I posted yesterday. One of which was definitely legit.

Boosted, IK22s will probably do the trick for a considerable amount of power. Overseas in hot climates and inconsistent fuel I recommend the 24s for most applications including the high power guys as an insurance measure. Allows them to run enough timing to keep EGT in check and torque high.

I'm expecting to use the 24s when I get up and running on my next boosted setup. I expect a switch to E85 will carry me pretty far on the 24s.

27s would be the next step, but at what point that change would be necessary or beneficial is not clear yet.

 

I have a Mallory Hy-Fire box on a GMC Safari cargo van with 4.3L Vortec v6 that also has a Hyper-Tech programmer, intake and exhaust changes... The thing pinged like hell with one heat range colder plugs but was fine after dropping two ranges and smaller electrode plugs with larger gap adjustment .. There was a big difference in throttle response, low end torque and fuel mileage.... I had the same results on a Harley Shovel Head engine that was running 2 Accel coils and 2 spark plugs per cylinder with a Mallory box.. I had a lot more time and money in that bike than in my Fit... With 4 coils that allow more ignition dwell time an ignition boost box wouldn't seem likely to do much... In the old days these type of boxes were referred to as dwell extenders... Here is a link to the only thing I have seen that is available for a Fit.. HKS Twin Power

 

:Has anyone tried to run anything other than the Honda or OEM replacement coil packs? I am having a hot stumble at idle issue...thinking its the 60K coil pack failure. IF I could get my FlashPro to data log I could confirm it

 

I bought IK 24s on Amazon.com nearly a year ago.. You would need even colder plugs with an ignition box.. The ability to use more ignition advance, lean out the AF/R and being able to have 2 different tunes with the Flash-Pro is making an ignition box rather appealing.

 

I can't remember where and I cant find the original thread, but some one reviewed that HKS box when it was new and was not too happy. IIRC he burned up a set of plugs in a hurry...

 

Well.. if I need it due to excessive charge density/cylinder pressure with the compounds on kill mode, I would go for a CDI

 

I wish someone made aftermarket coilpacks

 

Out of curiosity, why would one need them?

A lot of stock ignitions are quite stout. I was running stock DSM ignition at ~67lbs/min and 38psi, and intend to see how far it will carry me now that I'm on a much bigger cam/turbo combo.

 

The AEM CDI pencil coils dont work? CDI Pencil Coils - Wideband O2 UEGO, Water/Methanol, Stand Alone Engine Management, Piggyback F/IC, Tru Boost Controller, Gauges, Automotive Performance Electronics

@DSM - I am only interested in an aftermarket solution as it seems that the OEM or factory replacement options continually seem to be giving people grief...

 

That is why I had to drop a down a couple of heat ranges on my Harley and Safari van... I had a 1.75" S&S Super B carburetor with and adjustable main jet but no accelerator pump on my Harley.. Despite having over a 1.5 to 1 boost in compression, very cold plugs, ported heads and racing cam, a light kick was enough to start it regardless of ambient temperature... I do think the HKS Twin Power is priced too high compared to what I spent on the Mallory boxes but that's like everything else marketed that is the only thing that will work on our cars....

 

DSM isnt honda though, and Im sure aftermarket ignition would aid in big turbo setups.

 

I certainly understand that

Just out of the couple of "big turbo" setups.. big for our little world at least, T3 framed.. there's not been spark blowout or other issues yet.

I think both the 440whp Fit overseas and the 530whp LEA are both on stock coils as well.

If anyones feeling generous.. a couple grand my way could get that theory tested in short order haha. I have everything from T25s through a small cover T4 that could be tucked into the engine bay on relatively short notice!

 

Hmm, these appear to require a CDI box and seem to be intended for people converting to coil on plug ignition from standard... I doubt these would work.

 

I think that being able to use a spark in a heat range that would be low enough to pull a great deal more heat from the combustion chamber thus allowing more ignition advance while also igniting a very lean A/F mix makes a lot of sense ...

 

This is something we just recently decided. Could be in the works if there is enough interest. With the Flashpro out and the capability of that, tuning your vehicle with just bolt ons seem to give it quite a good gain.

Upgrading the coilpacks will bring the performance even a step higher. I running upgraded coil packs on my EVO X and on stock plugs, and man, I have to say, that alone makes a world of a difference.

What do you guys think?

Sign me up! I currently am having intermittent misfires on 1 and 3 at a hot idle... If I have to spend $2xx on them I'd like at least better reliability than the dead in 60K OEM units...
