ford ecu or megajolt
andy188 - 16/10/14 at 07:10 PM

hi all,

Im running 2.ol zetec, with 135 bhp ford ecu with cbr600 bike carbs on my zetec, looking into megajolt, how much better is it, cannot find many rolling road print outs to show suggested improvement, has anybody got back to back test, or figures from there rolling road tests. thanks andy

What ford ignition only ecu are you using
Or do you mean the edis or esc unit

So I take it your running the pre pats rs1800 spec ecu as ignition only.

As you have no real way to tell what the ecu is doing or not doing with the lack of inputs I would go stand alone. I think I would skip the megjolt and go for a Nodiz due to the cost of edis 4 units. Its not like you can get a megajolt for £35 any more.

Or you could fuel inject using your ecu very locost

Get a latter Pats ecu and you can see all the engine parameters.

hi,
im running ford 2fbc ecu with ignition sencors wirred up, (tps, air & water temps &, crank). higher rev limit than old esc.

trying to find out how much better megajolt is, bhp gains against cost etc. (also can I do the pc work required).

Thanks

Andy

hi Wasa,

yeh running 1800 ecu we spoke about a year or so ago, its a lot smother than the esc I was using, you like your fuel injection don't you lol, have photos etc of one that was at trackday this year, think that would be a partial rebuild of my kit, (swirl pot, extra pump, extra fuel line ??). thanks for info, Nodiz not been out long, maps, realiability etc ??

rebuilding a Dutton with a zetec with my son that may go injection,(that's another story) pats ecu etc.

Yeh the return fuel line is a pain.

andy188 - 16/10/14 at 09:09 PM

yeh, it is when car is few years old lol, i should think ahead lol.

is the latter ecu usable with my wirring, how can I tell what the engine is doing, is that with the obd readouts,

its only going to be better if the ignition map on the ford ECU isn't quite right for the way your engine is setup


assuming you've got not big flat spots in the rev range or other issues that may be timing related then the aftermarket ones will just do pretty much the same job as the ford one...

as long as your timing is fairly close at higher revs your probably not going to see any difference to the max power
also since your already running a TPS (i.e a 3D map) you'll probably not save much fuel either


so unless you've got any obvious issues with ignition timing - your unlikely to get any significant gains

the ability to see whats going on and make changes to the map is the real advantage - that and setting your own rev limit

+1 for the Nodiz, have used one for 2 years , been faultless, very easy to set up, and lots of additional spec compared with a Mega jolt. Inc the ign drivers. They are also easy to speak with and Matt is very helpful . They are bring out a combined system for fuel and Ign. You may still be able to reg for a betta version.

Always nice to see great feedback on the Nodiz Pro - Cheers guys

The OEM map will not be very good on carbs - due to them expecting longer inlet runners - if you want simplicity the Nodiz is the answer, have plenty of basemaps for Zetecs also Mapped hundreds of them now! hehe
