A few questions about fuel system and N/A tuning

anyone else? Actaully, the only time I have heard about it was before they came out with the vehicle specific harness.

This was awhile back though (HKS could have resolved the issue if there was any), and word of mouth, so dunno

I spent a good month trying to figure out which to get when I had mine, as I had always used MSD in the past on my mustangs. The harness sold it for me.

The coil is supplied +12 [11-14] volts from alternator/battery................the only way you can increase output voltage is to raise the battery /alternator voltage!
If the so called amplifier has a REAL WAY to accomplish this I would like to see some proof. Some of the boxes change the spark duration TIME but not the voltage!
The proof would be an accurate dyno with multiple same day runs on, off, on, off At least 3 runs in each condition to minimize +- 3HP dyno error repeatability accuracy.

“provide optimum spark duration and maximum voltage output”
So is this to imply that OEM doesn’t maximize the available voltage?... So this is able to more efficiently use what is available?...
Are you saying it’s just a longer spark, but not necessarily and bigger spark?
If so, would this not accomplish the claims: “resulting in crisper throttle response and a smoother engine powerband”
WOW - this turned into a MAJOR thread jack... I'm sorry OP

You have no idea what you are talking about,Plus the fact, you tell big stories about how smart you are.
I wish people like you would just go away. One reason, I do not post at driver with dorks like you.

NA, the factory voltage is more than what you need.
The vq likes the plugs degreed in with the open point of the plug between the exhaust &intake ports.
you will find more gains with indexing your plugs NA than installing a multi spark unit.
The MSD unit is wonderful in high compression engines with wild cam shaft timing.
I would try a new set of plugs one step hotter, and close the gap .002 tighter.
try to get just the electrode in the combustion chamber without any part of the threads of the plug exposed.
polish any high spots off the tips so they do not start glowing in the chamber.
Simple is good and it works.
PS do not listen to that moron ,,,,,,,,,,,,,,,,Rick

If you noticed, Mr. Super **** - you haven't given anything constructive here...so its you who needs to leave...
damn super d i c k !

I guess those low compression FI guys really screw up then when they upgrade their ignition systems???? According to you at least....
Go kiss your blow hole goodbye already!!!
BTW - a larger, hotter and more consistent stronger spark, is what burns more fuel, more efficiently - which in turn, produces more horsepower, produces better starts, promotes smoother idle, provides for smoother acceleration and throttle response...oh yea, and better emissions.
You can accomplish this by....NOT CLOSING THE GAP ON THE SPARK PLUG, but opening it - and increasing the ignition systems to accommodate the gap to provide an even larger spark - providing, yet again, even more benefit.
Ideally - you want the coldest plug possible without fouling. Smaller gaps, produce smaller, faster sparks. The sparks burn out faster. This is useful for trying to solve detonation and pre-ignition and other ignition issues - that are also inherent in FI/nitrous, high compression, etc. cars. Hotter plugs are poster children for detonation...so I would never make that suggestion....but I guess that's ok for PASTA BOY!
Whether or not it's HKS or MSD - the point of this thread is: Ignition Systems
1 - they are useful
2 - which units are 'better' - they are about the same, BUT, the HKS is a safer bet and far more widely used on Z's and G's because of it's size and vehicle specific harness. The MSD - is much cheaper however, and larger, and there's little room in the engine compartment as it is. The MSD is far more widely used, in the import crowd, on Honda's, etc., and far more in the American muscle arena.
3 - If colder plugs and hotter sparks are better..then why put in hotter plugs and smaller gaps, on a stock ignition system....
4 - The stock ignition system - is VERY good to begin with. Better spark, never hurts performance and general operability...never.
Ultimately - you have to figure out if the price is worth the gain, if the purchase is bling related, if the purchase is for protection based on the build....
Lastly...don't eat PASTA while installing your ignition systems!

Simple to create [buy adapter] a high voltage cable extension between coil and plug and sample the high voltage and view it on an oscilloscope. To scientifically observe any changes improvements after market ignitions might provide.
