hi all im trying to get all the bits i need for my zetec conversion before the winter season so a few questions

is this megajolt a 3D? does it matter if not? i have a blacktop 2.0l zetec and will be running zx6 bike carbs & 1.8 zetec flywheel + tps

As I understand it.

What makes a Megajolt "3D" will be the fact that it has some type of feedback sytem.

This can either be in the form of a MAP - inlet manifold pressure sensor, or a TPS (Throttle position sensor). Either of these systems will allow the Megajolt to alter the timing etc depending on the engine load/performance.

My set-up I had in the Pinto was a "2D" as it had no TPS or MAP. it purely worked on engine revs - As the revs changed so did the timing advance/retard to the ignition. Evene this was head and shoulders above the dizzy set-up, especially cold starting.


I am sure the above is not the full answer and others may well say I am wrong . But, I am quite pleased how much I have learnt in the last year or so (or think I have )


Now to start getting my head round the injection OMEX 600



So, in summary, you will need either a TPS running from the carb spindle, or a MAP sensor taken from the inlet manifold.


EDIT - Just noticed you mention you have TPS. So just hook up the TPS wires to the MJ, get a suitable map and you will be 3D

The new edition of PPC mag may be of help , it has an article on fitting and setting up Megajolt. I haven't had a chance to read the full article yet but it should be of help?

Hi Lewis,

Yes megajolt is 3D if you use MAP or TPS.

My setup is exactly the same as yours - 2.0 Blacktop and ZX6 Carbs. The carbs should have a TPS if from a recent model and work great on that engine.

If you need a megajolt map let me know as mine seems pretty good. My carbs are running 1.6mm jets.

thanks for the replys guys ill think ill order one of them & whitestu a copy of your map would be fantastic! u2u sent
