Hi, i recently put a punto 60 engine into my mk2 uno. I rebuilt the engine, new main and big end shells, new piston rings full gasket set and had the crank, pistons, conrods and flywheel lightened and balanced.

I'm still running all of the uno ignition and fueling though. It works great and pulls well but i really want to use the tricker throttle body i've got sitting under the bed and i don't want to butcher the 1.0 wiring loom incase someone else needs it.

Is it simply get the wiring loom from a mk1 8v punto, get any ecu from a pu to 55/60 or seicento/sporting. Use a mckritch chip or the same chip but cheaper in the seicento classifieds and thats it?

The uno system doesn't use a map sensor, doesn't have a crank or cam sensor.

I have the crank pully with the notches so i can just put that on and get a punto alternator as the belts differ between puntos and unos.

Will i need to get the twin coils and as well? I don't know if the puntos system soes fueling and ignition or if it is split like the unos as the uno ignition is done by a distributor.

Thanks
Dan

No one knows anything that would help me?...

Still need advice on this ?

didnt solve it in 5 years?

Been in the garage and not touched it till recently lol. I'm going to fit a punto 75 head and inlet and low boost turbo it, I want to run the punto 60 loom so I can use coil packs and got my McKritch chip rather than a distributor, I will use my 40mm tricker throttle body on the 75 inlet and use the 75 injectors to batch fire when on boost. The uno ECU and wiring only go to the engine where as the punto loom has other block connectors so I'm thinking that they go to a body control modual, I'm not sure if I can just for the punto loom to the crank sensor, map sensor etc and just leave the block connectors or if they are going to need a feed of some sort for the wiring to work.

interesting one.. I would kinda advise against your plan really. My old seicento turbo that was always my plan and i sold all the bits with the car to paul who now owns it. Its since had the P75 head, inlet fitted to it. It runs a tricker 40mm TB on the p75 inlet and the the mpi rail is powered by an mf2 on boost.

Few things I must say about this setup, when running it on the spi ecu from when it was spi with a 2nd injector it used to die all the time when you came off the accelerator, like when pulling upto lights and stuff. So the ecu was changed to a P75 one - still running the 40mm TB and mf2 powering the mpi rail. Now this does work, car is a little rocketship. But it really isn't the best running car. What it really needs now and this is what is happening next is it needs management to just run the mpi rail and not use the spi TB at all - I am meant to be helping wire in a DET3 soon.

Ignoring all that for a mo - when it comes to fitting the actual loom and ecu to the engine, this is going to be pretty much the same task as I am going through atm fitting a full P75 engine into my 750 panda. It should be pretty straight forward. If you plug in all the connectors for the engine you really shouldn't have that much left on the loom. There is a big connector that does to a twin relay (little white box) which controls the coils, usually thats still there when you looms are removed.
There is on most of the looms (they differ from each other a bit depending on what car they are from) there is a bundle of wires that all go to a ring style connectors, that needs to be earthed, there is several good unused bolt holes on the rear of the block you can use for that.
There is a little square connector on the engine loom which is the 12v supply, connects straight to the +ve side of the battery - a nice clean way to do this would be to get the +ve battery loom off a donor like a mk1 punto or cinq/sei spi and then it will have the connector right there - only other thing on it is for alternator and starter.
You will also want to add at least one extra earth, find one of two spots you can attached a decent earth lead to the body and connect up to the gearbox and engine smoewhere - cannot have enough earths!!!
I think that will leave you with the D4 connector, which is the big connector that on the donor would have attached the engine loom to the body loom - you shouldn't really need much on this, the signal for the tacho goes through this - if your ecu is immobilsed there is wires for that but i advise just getting it removed. But generally speaking most the stuff that goes through that the uno will already have a wire for, oil pressure sender for example is in same place and should have same wire so just plug in the uno one and thats already wired to the dash. speedo is cable from box so that will work. I've sat down and properly gone through it myself yet but should be pretty easy.
dragonman can prob help some from his p75 panda conversion - is who i am gonna ask if/when i get stuck lol

That is exactly what I needed to know. Thank you blu73.

I'm now going to be buying a 1.3 uno turbo engine and box along with everything else needed to convert my 1.0 to a turbo ? Thanks again.
