HT Lead fed Tacho for Hornet

I normally use a cheap £25 tacho for when I do trackdays, but it packed in at Oulton Park the other week which left me at the mercy of the noise-testing jobsworths which meant I missed my first session.

This tacho normally has the wires fed into the open connectors where the original clocks go, but the noise-testers had a portable rev counter that could clip onto my (easily accessible) HT lead which worked pretty well.

I've had a look round and it appears that you can get tacho's which will work by being fed off the HT lead, which means I won't have to fanny around poking wires into existing connectors.

I've found these tacho's by Scitsu however I have a few questions:

1. Does a Honda Hornet have a wasted spark? I haven't read anywhere saying it does, so would assume this would be the one I need:

Not much help as they're more expensive I think, but the veypor system does tacho like this as well as lots of other fancy stuff.

I think mine was around £200 a few years ago, but that was for the more expensive model.

Hey, sorry it took me a while to reply.

Yeah, that's the one you want. The "blue" one. Mine goes up to 16k, but obviously the hornt won't rev that high.

Scitsu don't make the "auto" ones anymore, so it's rechargable ones or nothing, I thought I had an auto one, but I actually had a normal re-chargeable one.

Mine's working fine now it's recharged. Laughing

I got Scitsu to send me out a charge lead then you just connect it to any 12v battery and connect the cable to the tacho.

Elliott do Tacho's too, but they are similar money.

Most of the hornet cup guys use Scitsu or Elliott stuff. Why not just use the stock clocks?

Wait till tomorrow.

One of my suppliers has just started to seel Tacho's that go up to 16000rpm, I will check the price and availability as I believe they are about half the price of the Scitsu.

Thanks for your help guys

Hammy, I don't want to use the stock clocks because they're £350 new and not much less when second hand Sad

Sickpup, are they fed from the HT lead or just from the ECU?
