Magajolt Struggle!
Guys, I have been through a whole raft of information on the megajolt and I can't really say I am any wiser 
I can purchase the Megajolt from say AF Racing for £150.00 built up. But, do I need TPS? I am assuming I do but need coinfirmation from the experst
please!
I have the EDIS as it came with the engine so is there anything else I need?
Thanks for asking age old questions but....
Cheers,
John

TPS is throttle position sensor
MAP is "vacuum from inlet manifold"
if you intent to use bike carbs then yes you can set this up to give a full 3d map of Load on engine( map) versus throttle position versus RPM . All
you need to do is mount a potentiometer on the bar that moves the butterflies.
Would give you more tunning options.
I went with TPS option but use the map at moment. Whole system works well. Quite easy to install and use as well
I don;t have anything yet connected to the tps input as of yet but plan to connect in the throttle position sensor off of the GSXR 750 bike carbs i;m
using now. Car started life on Dellroto's with basic EDIS then went to megajolt then went to bike carbs.

Depending on what engine you are using you may also need a coil pack? Not sure what your set up is? On the subject of buying a built up megajolt kit,
do a search on here for a chap called Martin Millener. You can buy a ready made megajolt kit including software and RS232 cable from him for around
£100 inc p&p. That may save you £50 for starters.

Buying a Megajolt
I think you will find that Ray Ward, on this site will sell you a built Megajolt for a lot less than £150.

You will need a coil pack and as youv got edis i assume youv got the crankshaft sensor?
You dont have to have a TPS or MAP sensor connected as you can run on 2D maps. But 3D with one is much better. Its easy to do.
If your not running a single carb setup id go for TPS rather than map. I think for MAP youl need a take off from each inlet piped into a swirl pop
to balance it out for the MAP reading. So if your running twin's 40's/45's or bike carbs youl need this system. TPS is much
easier.
This site might be of use if you havent already seen it.

Just to add. You will get just an MJ unit for much less than 150 quid. Get the kit for 36 and get someone on here to build it for you??

John,
I was just about to recommend the same site as Dan! I found it very helpful.
What engine are you going to use it on? Mine's a crossflow, and that wasn't too hard to modify. I believe that the Pinto is also quite
easy. Some are very easy, as they already have a place for the VR sensor, with holes on the flywheel to match.
Whatever you've got, you should find that the engine runs a lot better with MJ!
It's also worth looking at the Megajolt site itself, as ready-made TPS units are $144, which works out
to around £70 - £80. You will get stung for import duty and VAT, but I still reckon you'll end up paying less than £150.
cheers,
David

Cheers Guys, execellent feedback, even though its way above my head - for now 
I forgot to mention what i was running, my apologies!
Zetec 1.8 with R6 carbs
Thanks again and I will look at the info.
Daveg - once i digest the info i may well be back to you...
Regards,

To keep it simple;
If you have zetec you will probs have the EDIOS and coil pack (inc leads etc). That is a good start.
The zetec will probs still have the crank sensor in place too (i think on the zetec it is on the flywheel end - iirc the flywheel has the 36-1 teeth
forged in as standard).
All you will need is the MJLJ box itself for now and some wiring bits. Can be bought way less than £150. I got the kimmins version with EDIS built in
for £100.
Wiring is very easy. Getting the car running is also very easy on a zetec. You may have some communication bits to sort out with the laptop but there
is a wealth of experience here to make that easy also.
If you are as much of a novice as you say then take it one step at a time. Get the MJLJ sourced first. Try and go for the latest firmware and software
if you can. If not they are upgradeable anyway. The autosprts lab site is fantastic.

No Probs - i managed with a Pinto which is a little harder (no crank sensor or toothed wheel for starters so these have to be retro fitted).
Only problem i came up against was comms with the laptop but Brent has been working his magic and the new software is far better.
Im only running 2D mode at the mo and that is far better than the dizzy. 3D will wait for the bike carbs but this only involves retro fitting a TPS -
some bike carbs have these fitted as std so just need wiring in.
