   Hi friends, I have a Single Plug VTR Engine I'm going to put into my 3 plug Saxo.
   I'm rebuilding the Engine completely, The loom will be the last thing I look at but I know I'll need to change some things because it's a Single plug and the Engine in the car now is 3 plug.
   
   So I'm wondering what will I have to change? Could I buy a single plug ECU for the Engine and that'll work?
   
   I have the ECU for the Engine but it's not unlocked, I am going to buy a Standalone ECU anyways. So if I was to buy a single plug ECU sould I still need to change stuff on the Engine?
   
   Could I change some Sensors around or something?
   
   How would I go about making the change? Would I make it 3 or Single plug in the end? What is simpler and what are the differences?
   
   Thanks Friends, Merry Christmas!

   single plug and triple plugs vtr engines require their respective looms and ecus to run. You would need to cut the loom to bits and wire it into the interior loom.
   Or you would need to swap the interior loom and clocks to a single plug
   Your best bet its getting a 3plug engine loom and ecu that matches your car

   I thought as much, So if I was to buy a 3 plug Loom and ECU, would that loom fit straight into the Engine that currently has a Single plug Loom on it?

   O dear lol, I thought the Engine were almost the same but with different sensors, I was told it was fairly simple to change them to 3 plug =/
   
   Hmmm This is a problem lol

   well you can, you just need to rewire the loom into a different plug and get all the wires to match up

   Now is that complecated or is it a case of buying a 3 plug loom and ECU and fitting new sensors, or dose the 3 plug loom have more sensors? I'll have to do it some how lol
   
   I'll loose money selling the Engine on, and I want to learn how to do it anyways...

   no you cant do that. Because one engines 90bhp and the others 98bhp
   
   You would have to use a single plug loom and ecu to match the engine. Then cut the plug off the loom.
   Then rewire it onto a 3plug loom plug. So that they actually can connect together as they are 2 different sizes.
   When rewiring the plug you would need to match the wires from the engine loom to the interior loom.
   Its not something for beginners really.
   
   The easy option is to get a new engine loom and ecu which will bolt straight into your car with no messing about

    Oh, I think I've said that before, sorry if I'm making this complecated. I think I've said somewhere Can I buy a new ECU and Loom? I've got to buy a new ECU anyways because the one for the Engine is not unlocked and I was going to buy a Standalone ECU anyways, So Are you saying I could buy a new loom and ECU that match, but how would I make that match the Car Loom?
    
    I'm a little confused as to why I can't buy a 3 plug Loom and a Standalone ECU for it? Are the Sensor holes on the Engine Different to the loom or something? Or will the 3 plug VTR Loom not fit to my 3 plug 1.1 car loom? They're the Same year lol.
    
    I'm eger to learn about this sorry if I'm going round and round on this mate.

    3plug loom to 3 plug car will fit no problems
    
    the issue is you want to use a 3plug loom and ecu on a single plug engine. The map will be wrong for the engine and the sensors are different. 3plug engines create more power than a single plug vtr.
    
    Whatever is in your head forget it and replace it with this
    Get rid of everything to do with the single plug engine.
    Buy a 3plug vtr engine, loom and ecu.
    That way you can just fit it no messing about. Everything matches and works in harmony.
    Bike carbs are more difficult to setup than you think.

    Ahh right, Well thanks for the help, I'm very greatful but as I've started rebuilding this Engine and I have the Cam, Lightend flywheel Etc... I think I'm going to see it through, Carbs do seem a nice option and I know more about Carbs than these injection Engines as I work on Carbed Engines more, I'm in no rush this project is planned to take about 2 years anyways Mainly because I can't get insured on it yet haha.
    
    Merry Christmas!

    thanks button carbs are a very backwards way of tuning

    Lol you got it mate.
    
    And yeh but I'm not really looking for a quick way or getting power... I want something different and I want to learn as much as I can while doing it, it's all about fun for me not rushing to get this done, I want it perfect and I want to be 100% happy with my choices on the Car
