   Hello everyone,
   I have just purchased a saxo 1.1 to use as a road legal track project... Main idea is vts lump new suspension etc etc. I was looking at the ecu and it seems to differ from the others I've seen. Has anyone seen this particular ecu before or am I mistaken and it's just a standard ecu? Any help would be appreciated

   Bosch M7.4 ECU. Same family as used on later VTRs.

   If you unbolt the ecu there should be a serial number on the underside of it, or even better a make and model.

    Yes there should be a sticker underneath saying it's a Bosch Motronic MP7.4.4, some VTRs used this ecu but all the VTSs used Magnetti Marelli ecus.

    What you need:
    3 plug VTS engine
    3 Plug VTS ECU (unlocked or with all the immobiliser gear)
    
    No need to uprate fuel pump or anything.
    You might need to run a return line back to the tank.

    Ohh you might need a 3 plug VTS engine loom itself,
    
    although I think the 8v loom can be used if you extend the MAP sensor wires so it reaches the other side of the 16v inlet.

    You will need the vts engine loom, vtr will not give the best results!
    Or just buy an a knackered vts and swop all the bits you want over!

    No point in remapping with the filter 'zorst combo!
    
    Only needed after camming!

    You MUST use matching loom and ECU because the Marelli pinout (16V engines) and the Bosch 3-plug pinout are very different, even though the connectors are the same and will plug into the wrong ECU. Damage will be almost certain.
    
    It would be possible to use the 8V loom and ECU (with a coil connector change) on the 16v engine (and thus keep your immo function intact) but the bill for mapping the 8v ECU to suit the 16v engine simply wouldn't be worth it because you'll buy a 16v loom and ECU for less money.
    
    Plus the 16v ECUs are more easily tuned if you decide to go further later.

    Ah much appreciated. I was contemplating a unichip ecu, I've seen some going very reasonably priced on the Internet. Has anyone had any experience with these?

    I have the opportunity to purchase a 106 gti lump already running cat cams with a ported head, history of a rebuild and it comes with a 4-2-1 manifold. My question is... What do I need to run the gti engine in my saxo. It's currently having everything ripped out from under the bonnet so I don't mind loom etc but do I have to get a gti loom or will a vts one work likewise with the ecu as I'm aware they are very similar. Very naive of me I know. Any help is greatly appreciated

    a 3 plug VTS loom and ECU will work in your car with a 106 GTi engine. The engines are the same, as are the gearboxes etc.
    
    You may need to swap a few sensors over depending on the age of the GTi engine.

    Lovely 106 looms are like rocking horse sh** to get hold of so that's marvelous. Is there an easy way to tell what engine era it's from from looking? Ie mk1 mk2 etc

    There's no point mapping your (effectively standard) car. At all. Run with the stock 16v ecu. Just buy a 16v ecu and engine loom, and splice it into your existing car loom. If you're not comfortable doing that there's several people on the forum who can help. For ease, stick with the type of loom you've got now - 3 plug or single plug ECU loom (I didn't read what you have currently). You can splice a 3 plug loom to a single plug, but it's creating more work.

    Yes, the cylinder head usually gives it away.
    
    3 plug later styles have an air pump, or a hole on the head which has been blanked off by a plate. They also have 2 square blocks in the middle of the head (again a feature for the air pump.
    
    single plug models don't have these features.
    
    Physically, the engines are the same spec. So a single plug engine, will work with a 3 plug loom if you swap/fit the 3 plug sensors as the connectors are different shape for the MAP/TPS etc.
