Regarding two step launch, the hardware is ready for it but they havnt done the software? Is that the case?

The map switch has the clutch pedal sensor connector part on it already.

 

so what was the price of it at z1

 

Thanks Rick =)
I like hyper voltage system, and is looking to do sth with the ignition system soon

Do you guys know when is it a good time to change the spark plugs?

 

Nissan recommends 100K mile, but NA I melted a grounding strap to the elctrode in a cylinder of course causing a nasty misfire. Long story shot I swapped to 50K and the plugs looked like DEATH! Car felt much better with the new plugs. Id say 40-50K miles swap em, for the money and the easy install its a small price to pay for keeping the engine running strong.

 

I concur, my plugs were white. BTW $499 was the price at Z1, not including shipping, which was like $15.

 

I am only at like 22k miles.. lol
I guess I will do it at 50k miles =)

thanks for the info

 

Cripes! Is on top of the engine the recommended mounting location?

 

$499 at www.hopupracing.com as well.

 

Ok, from the sites I've seen (including HKS), it looked like you had to buy an application specific harness separately. Thanks for clearing that up.

 

They are on backorder for 2 months at Hopup, BTW, the unit comes with the harness for the 350Z.

 

this all sounds very interesting

i never knew this part existed or that our engines were direct injection

what gapped plugs are on the market to match with this HKS unit, or do you have to gap the plugs yourslef?

 

Are there any differences besides brand?

 

I gapped my plugs at .045. Again, my undersatnding is the the Sun system helps with getting lost volts to the plugs whereas the HKS system magnifies the signal to the plugs. And I gapped the new Iridiums myself.

 

William...you're not the only ones that has them

The harness is necessary - you cannot install it without it.

I'll be doing a before/after dyno on my car in the coming weeks, so stay tuned. I have a DLI II sitting here waiting to be installed

 

great, will be looking forward to dyno results before purchasing

can we buy pre gapped iridium plugs for the Z?

 

I just threw my NGK iridiium IX as is out of the box into the 350Z, runs fine.. :|

I think according to my crappy gapper that they were .44 or .43.. couldn't tell .. lols ?

 

i wouldnt have a clue how to gap plugs myself, will have to hit google now

 

thanks...I'll give THEM a call.

 

we just got some more in today for those looking for one

 

so are the sun auto ground systems any good at all? they are at a good price compared to $500 for the hks.....
