Ignitech, not only tricker and more cost effective but also improves your power to weight ration instantly by saving weight

How much less does it weigh than a standard cdi??

The same improvement could probably be had by not wearing socks underneath your boots!

i think the ignitech is heavier than the pair to be honest as there full of water proof resin, either way ignitech is the more logical option if you can get it to work right (i cant yet)

ive just sold mine for £135 and bought a ignitech

How much!! I thought I was taking the p!$$ when I sold mine for £80.

Saying that though I've just seen one on ebay (buy it now) for £199!!!!

There are some dreamers in the world!!

I took mine apart over the weekend after reading this thread.

It does have more than just a resistor in it.

Then I did some digging and phoned up one of my friends from the ForceV4 OC in Japan.

The SP unit is supposed to raise the rev-limiter, alter the ignition timing slightly and remove the de-restriction.

However, I believe it is supposed to be used with the other HRC parts to work effectivly.

I really can't see how people can pay so much money for something because it has HRC written on it. Unless you have the rest of the set-up you wont be able to use it to its full advantage.

An ignitech box is cheaper than a lot of people ask for these and has much more functionality, it can be tailor mapped to your individual bikes set-up, becuase after-all how many people have an exact HRC setup?

The ignitech also offers more advanced features.

The most useful part of the HRC SP box for a standard bike is the de-restrictor, which can be achived for free.

Talking of HRC SP boxes et al.

Perhaps one of the trickest NC30's i've seen

Was just kidding about the weight

Have used mine to change the rev limit and make the tacho accurate too. Great little toys.

Neosophist dont suppose you took any pics of the inside of the SP unit?

I'm dubious of what this guy has told you as an hrc cdi was offered for the nc30 which would supposedly do all of this.

On the nc30.jp website it has a small clip of the tacho before and after the hrc cdi is fitted. It clearly effects the timing.

I've seen all sorts of claims of what the sp units can do on jap sites also (let alone on ebay lol!). I personally think there's a lot of misinformation out there, but I could be wrong, it may do more than remove the speed limit.

i remember this discussion getting heated over my opinions over this before either way i dont particulary care now, its sold and i have an ignitech,

but WHY would HRC go to the trouble to make such a weighty "metal box" if it offers the same thing a 22pence resistor would, in auz moneys thats less than a Dollar your end, i was convinced there was a little more to it, especially with the RPM, and curve, but hey ho as i said i dont care no more,

Ignitech is the solution, and ive set it to 14.500RPM

will gear shift light at 12.500RPM just need a loom/plug from rick o and then im going to uutilise the unuse ORANGE & BLUE WIRE as it goes to the clock unused on the Ignitech saves having to run another cable down the bike :)

They can't exactly offer a resistor as part of their race kit for people to solder in, they ideally need to have a plug and play part. I doubt also that many people knew of the resistor mod at the time the sp unit was offered.

I think the function of the sp unit can be found out if we knew the jap 400cc supersport rules. If there is no ignition/timing alterations allowed then the sp unit won't be doing this. The sp unit replaced the F3 cdi when the rules were changed...

Maybe some of the nsr guys know what the sp box does for the nsr, it's essentially the same unit as the nc30 box.

FWIW, Michael on the nc30.jp website (awesome nc30) has the 'proper' hrc cdi fitted and an sp unit to his bike.

be good for a picture, mart do you still have it apart,

get them on ebay afterwards i had some offers for £110 as i had a best offer but i removed it as i wanted £135 just so i could buy an ignitech!

i ripped apart my standard nc30 OKI CDI there other day to see whats was within, ill get pics if required there are HONDA chips and OKI chips! didnt know honda did electronics i thought that was just left to OKI.

It'd be interesting to see if it actually raises the rev-limit or just affects the tacho as there not the most accurate anyhow...

Still better than my ZXR one, unless it really is red-lining at 17,000rpm

I did have a digital tacho-somewhere. It'd be a good test to find out testing them side-by side.

Yeah i'll dig a picture up.

I was under the impression it meerely removed the restriction but it looks overly-complex to do just that.

Plus if it did just that wouldn't it have made more sense to connect it directly to the plug near the clocks where the speed limiter goes, like the one for the ZXR, rather than have 5 or 6 wires interface with the ignition box? Unless Honda were deliberatly upping the cost of it?

Even if it does advance the timing im still firm on the beliefe that it isnt worth the money unless your building an exact hrc rep, as an ignitech is chepaer and customisable.

Some guy brought one and said it didnt' make a great deal of difference but he is under the imrpession the ignition timing is changed, but you need the exhaust system too?

Gah, I had a little picture of the SP kit page but its gone away! >.< It says you need to run high-ocatane unleaded fuel with it, which also supports the advanced ignition theory.. i'll keep digging :)
