Default Megajolt ECU

where can i get a megajolt ecu from for my zetec on bike carbs?

im guessing i need ignition only as its running injection now.


thanks

You can get them direct either fully built or in kit form, but if you've never soldered before i'd buy the fully built version. Surface mount, is very tricky...

If it's running injection, you need a ecu that does both fuelling and ignition, unless the "carbs" you refer to really are carbs, but more likely throttle bodies with injectors in them ?

Why not just run the normal factory management? If the engine is relatively standard (eg, compression ratio) then you're not going to win anything by adjusting the timing.

bogg brothers told me it can be run on standard management but runs terrible.

he said for best results go for megajolt

im lost with management so just took what he said

cheers

Not true at all, the injection to carbs is like putting a lawnmower engine in a F1 in real terms ie a serious backward step, but up to you.
As the fuelling will be totally different now with carbs instead of injection, the ignition curve will be totally different.
It will run on the old ignition map on ther std ecu, but nothing remotely like it's full potential, particularly low down with low air speed through carbs.
Without a doubt get a ignition ecu, or you are just wasting your money.
The one you have shown(if they are any good) will do the job, as a rough rule you will need loads more initial advance but less total, but no doubt in the future you will want to add tune up bits so need the adjustability that the ecu gives you.
Unbeleivably some makers still use MECHANICAL advance retard dizzies ie TVR, my god that is from the dark ages, little wonder they love aftermarket ecu's that control the timing.

Pob,
You are missing the whole picture, he is going from a efi engine to a carb engine, as to why you don't think it a backward step ask how many people agree with you, name just ONE carb fed engine in a car still produced today, and I'll easily name you 100 that are FI.
There is a typical max bhp at all costs, this does NOT make a great engine, power spread and torque are vastly more important, the 145 you quote is peanuts, and no doubt would be blasted into the weeds by a decent set up 120bhp engine in a real race, due to tractability that efi has over carbs.
You will never in a million years match that with carbs, he could use the existing ecu(ford) to run the TB's with mapping to suit, the ecu doesn't know or care what it is controlling.
It would have the added benefit of better economy and a pass if cat is required for mot ?
With ecu's costing what they do it is a serious consideration, but so is fuel economy, and the ability to easily use ecu on the next car.
Very true you can match sometimes the bhp or torque with carbs versus a EFI, but never with the same driveability, or mpg.

Well at the moment i have a 2.0 zetec and was going to run bike carbs and megajolt the total cost will be under £100. Bike throttle bodies are out of my price range at moment so are you saying i would be better going out and buying the zetec loom and running the standard ECU? Car is a Mk4 Escort and i was hoping for 160bhp rather than the standard zetec 130?

Just asking becouse this does seem a popular mod for people on a budget?

when i said its running injection i meant its a standard zetec, rs1800 efi (which has the edis module etc) engine and i want to put bike carbs on, because for a manifold and carbs it'll cost about £150 plus the management and bogg bro's will fit and setup for £400 which will work out cheaper than tb's

what sort of mpg can you get out of a zetec on carbs? is it usually from 25-30?

has been a good read of peoples opinions on the matter but aslong as mpg isnt too bad and the car is quicker than it is now, it should be worth it

depends how you drive it as regards your mpg, i have a ka on bike bodies from bogg brothers, injection and run by a omex ecu, i can get 250miles to a tank of v power which is £35, motorway driving, but i also get 35 miles to £10 if im driving hard, i would pressume carbs being worse as you carnt control the fueling as well

You really are missing the point it would be more powerful with efi, that's not the point, neither is "strangling the the car with injection", no they are so much more effecient they naturally run leaner mixes due to higher air speed.
I would never run a engine of any kind on carbs unless rules dictated it, does anyone else ?
I agree with the ford system on some of thier cars, but they have also done some ace stuff too.
I can't see the point of a std ecu if you are going to seriously tinker mod wise.
The main point pob that you missed though is THIS WAS AIMED AT THE AUTHOR OF THE QUESTION.
For the record I get 350+ to a tank from my cossie, now it is mapped correctly instead of aftermarket hit and miss chips, and now it is NOT on closed loop, worst idea I had that was.
