Mk6 (2006) Fiesta 1.4 Duratec (Sigma) bike carbs

Hi Everyone

Please can someone help me with some advise for my bike carb conversion on my Fiesta?

Ive junked all the EFI and installed a set of 600 carbs on a DanST Manifold with a Nodiz Ignition only ECU ()

Ive got it pulling juice from the tank via a bike fuel pump and it will just about run (With a manual choke installed) however when i rev it up it misses, pops and splutters. The Nodiz loom picks up on the crank sensor and replaces the plug to the coil.

However i have noticed that the alternator is only putting out around 12v which could account for the fact it wont rev cleanly, however there seemed to be around 5 plugs that went to various things around the EFI & Manifold that are now disconnected (All eventually going into the big Grey plug which is still plugged in)

Now i guess the alternator could be bad but i'd be very surprised as the car has only done 60k miles and seems a huge coincidence, especially as lots of things have now been removed/unplugged.

I was wondering if anyone else has done a bike carb/normal carb conversion on this engine (or perhaps any other EFI Ford engine) and experienced these issues?

Thanks in advance guys.

Any/all help much appreciated

    Hi ST, I'm going to chime in to start , despite having very little knowledge, so take any suggestions accordingly!
     
    I'm interested in doing what you are playing with, and possibly have the same 600 carb, but they will go onto my Pinto, and most likely end up using a Dans manifold also, but arent at that stage yet.
    Theres a couple of the Escort guys on here planning to do similar down the track.
     
    So, assuming the car was essentially running fine before going to ITB's, and its now basically ok with fuel pressure,  crank and spark timing. If the rest of the EFI was 'junked", how does the Nodiz know TPS, Airflow or MAP or exhaust gas mixture?
    Sorry I havent played with Nodis, and dont know what its picked up or whats  connected to as far as the rest of the sensors go. What do you tune it with?
     
    I'm planning to use open source Speeduino for control ( I have built it but need to get back to it) , and in that case once the sensors are all connected to the unit, you then calibrate the sensors ( eg for WOT) and then it has to have a very basic base map loaded, before the car can start. Then you can play away.
     
    Will be interested to see how you get on!

    Deano I think he's got carbs, not itbs.
    The ecu on the fester will control more than just spark and sequencing fuel and also the drive by wire throttle so the ecu might just be having a big seizure with what's left connected isn't part of the plan of parameters being unplugged..
    Old mate on YouTube called Making For Motorsport has done a itb on a mot failure car just for fun before it went to the crusher !

    Nodiz picks up crank and TPS plus some others if you want but it should get running with just 4x wires apparently.
    Can you send a pic of the carbs and anything else of interest ?
    Modern cars frighten me with the tech so I'm in the same category as Deano

    oh, yeah Marty, I should have read twice and typed once.
    I saw that YT as well when it came out.
     
    You are less frightened than I.
     
    Pics would avoid 1000 questions, but you'd still have to add or cobble together  a TPS to the carbs?

    The bike TPS can be dialled in thru nodiz, or use mass air flow if it's easier..

    Thanks for the replies guys.

    Yes, they are Mikuni Kawasaki 600 carbs (ZZR i think) . The Nodiz plugs into the Crank sensor and replaces the normal plug into the coil. There is a pinout for the TPS on the carbs, this isnt essential for basic running but is reqd for proper 3D mapping using the MEITE software from Motorsport Electronics.
     
    I have the engine running albeit badly and the dash is lit up like a chrstmas tree with errors and engine management lights, rev counter, temp gauge not working, battery light on as its not putting out the full charge i guess.

    I had a Mk2 Escort 1600 sport 30 odd years ago (If only i knew then what i know now) that ran like a bag of poop when the alternator went bad.
     
    It just seems a coincidence if it has gone pop. See Images below.
     

    Cheers

    Vid wont work and pic doesnt really give much away. I'll take more later but here is the car, although it now has a satin black bonnet with holes for carbs
