   Does the 1.5d has a ECU, and if it has one can it be replaced for a vts ECU and if so will it gain some additional power?

   every engine has a ecu and no it wont give much difference if u put a vts ecu in. imo any way

   not every car has an ECU as for power gains i think it would casue more problems trying to get it to run smooth

   yup the 1.5d has an ECU, however i doubt you could swap these and gain performance increase.
   
   I've never heard of this... is it possible :eer:???

   dude,
   
   if you want more power you can fiddle with the injector fuelling.
   
   there is a 'screw' or some sort of device that can be adjusted to allow more or less fuel into the cylinder. havent a clue where it is.
   
   also let too much fuel in and you'll be smoking badly.

   get a different engine. and a vts ecu wont work.

   how not? for the pric people pay for a new exhasut and induction kit they could have a 16v engine.

    i didnt buy a diesel to take an MPG hit... this guy might be in the same boat.
    
    plus apart from the engine conversion you'd have to do some serious fuel line and tanks cleaning.
    
    sadly the only derv in the saxo range is a NA'd 1.5, which isnt great compared to turbo'd versions.
    
    The engines are designed well within the material limits therefore plenty of room to improve the performance. more so than ANY of the petrol models.

    so your saying you can tune a deisal better than any petrol saxo??

    i find that quiet funny.
    so why do people tune vtr/s when they can tune a diesal??
    
    lol

    because the VTR/VTS has more power out of the bag.
    
    The diesel has 58hp as standard. therefore you'd never get 180bhp out of it like you potentially could out of a VTS engine.
    
    but what im saying is the derv engine has more scope for improvements, more so than the petrol versions - but that doesnt mean the engine will produce more power...

    basically derv engines a put under are lot more load than the equivalent petrol engines.
    
    dervs by nature produce more torque, thus more force that the components are subjected to. therefore the engines are built much stronger than petrol counterparts
    
    because of the high build quality, the engine is in a much better position to withstand the extra loads created by tuning.

    not everything happens the way the text books say.
    
    you could not get a diesal saxo to perform anywahere near as good as a petrol and it would be a complete waste of money in trying to do this.
    
    diesals are only good for towing.

    suprisingly, technology moves on...
    modern ones are just as good as petrol equivalents.
    
    diesel saxo vs an equivlent petrol (so 1.0 or 1.1) perhaps???
    
    surprisingly they perform exactly the same. except the derv does lots more mpg.

    how is a 1L an equivlent to a 1.5L lol
    
    we are on about saxos here..............

    because we are comparing derv to petrol not litreage... (at least i thought we were )
    
    diesel operates at lower rpms than petrol... thus it takes a larger displacement to produce the same power. because the engines are built stronger the masses of the components are higher, thus there is more inertia created by those parts...

    its goimg way off course here. it started out he wanted to improve the performance on his diesal. and imo its a waste of time on a 1.5D.

    ok in easy speak...
    
    turbo a saxo derv (normally 58hp)
    turbo a saxo 1.1 (nomally 60hp)
    
    which one can be tuned more...
