megajolt and bike carbs?

[onedayTM]

I have 1.8 zetec with bikes which does not have TPS, what do I need to get it going. Is it just trigger wheel and flywheel sensor, or do i need TPS and just cranks sensor. My megajolt does not have vacuum point.
any help welcome.
cheers tony

You can get the engine to run using crankshaft position sensor and EDIS 4 on its own.
You will need EDIS as Megajolt cannot drive the coilpack directly.
If you want a full 3d ignition setup you will have to add a TPS to the carbs.
Triggerwheels sell TPS sensors.

I'm running a 1.8 silvertop zetec with ZX6R carbs (no tps) and megajolt. As Dave says you just need a coil pack, use the crank position sensor and EDIS 4 unit. I am using a MAP sensor with my engine due to the lack of TPS on my carbs. I have just drilled and tapped my inlet manifold with an M3 tap and then fitted some welding tips drilled out to 2mm which are also loctited in place to make them air tight to the manifold. I've then teed the 4 vacuum feeds together and then they go into one of the plastic fuel filter housings which acts as a damping unit to smooth out the vacuum signal. This is then attached to Megajolt.

Using a MAP sensor has a few advantages over TPS in that it more accurately shows how the engine is breathing as TPS doesn't show load, only throttle opening. However MAP can be more of a faff to get a smooth signal from.

Yes i was hoping to do that but there is no connection on the back of my megajolt, it's one I bought of someone who was selling up and I see on the box it is from 2008. Looks like I will be fitting TPS.

You'll also find that you get better throttle response using TPS rather than MAP. MAP is only really neccesary for charged cars and emmission control.
