Tuning 1.0 ie mods

[thunderbird2]

Hi there friends,

I'm looking forward to buy a Uno 1.0 i.e. and work it a few modifications:

Install an air pump;

Reprogram the ECU to adapt it to this modification;

The objective is to make it a lot more responsive in low revs.

It's a really nice car that I always loved.

A few questions:

This car has mono injection, right?

Where's the ECU located?

Does it have an air mass meter / map sensor?

Thanks a bunch!
:slayer:

The Uno 1.0 i.e has a very basic form of single point fuel injection [SPI] that works like an electronic carburetor.
It has only one injector, with this spraying fuel into the inlet manifold

To my knowledge its not really a modifiable unit

ECU is just under the driver's side dashboard. You can get to it by pulling the piece of plastic, with an unexplained rectangular bulge in it, back.

 

[a73uk]

An air pump in the form of a turbocharger or one of these electric motor things?

 

[Ucof]

That's a point, he might just want something to keep the air bed in the back constantly inflated...

 

[a73uk]

Possibly an air bed.. possibly... um..

The weathers much better today isnt it..

 

[Ucof]

Possibly... the tyres? oh wait.. I getcha..


Yes it is - no need for inflatable umbrellas

AiR PumP ?

Something like a Lorry airpump, or a small compressor run off a belt to give short term bursts of compressed air, ideally inducing a venturi effect as well as cooling inlet temps!

 

[jo0lz]

Hmmmmmm
Interesting idea!
What about a set up like NOS but with a bottle of compressed air?
Then have a 12v compressor topping up the air tank.....

 

[tattyoldvan]

It does work, i've seen it in action. 600bhp NA(technically) mercedes v8 in a 300ce

Apparently gets 40mpg as well.

works on venturi effect uplike a superchager or turbo just increasing the air pressure above atmospheric.

negative is the size of tank required. this one has 150l lpg tank.
also a pump can't fill it quick enough to be used all the time.

Impressive bit of kit, only probs is i wasn't allowed to take pics

 

[jo0lz]

Hmmmmm
kind of like the technical progression of the old Ram Air Intake hoods you'd see on 60's American cars . . .

yes, something like this but the electrical one so I can play with it in tune with ECU.

but this mechanical type is also very nice

I'm interested in something to give, yes, that air bed constantly inflated and give the car a faster spool up

Sorry to disappoint you, but 'electric turbo/ superchargers' do not work. Certainly not the type you can buy on Ebay with all the wild claims that go with them. They simply cannot generate anywhere near enough air volume/ pressure to work as a forced induction system. If you fit one that looks like a computer fan (it probably is), all that is likely to happen is that it will cause a restriction within your air intake and will probably then get sucked into the airbox/ throttle body and cause all sorts of mayhem/ damage.

Ask yourself, why don't car manufacturers fit them to the cars they sell? Answer - because they don't work

Either fit a genuine supercharger or convert your car to a proper turbo installation. Otherwise you're better off looking into more conventional means of engine tuning.

Good luck!

have you already tried a 3 cylinder 1.0 vw/seat? what's in it?

... and, no, I don't want to supercharge it because it's not more power I'm after. Rather, better power.

HHHmmmmmm

VW - Three cylinder petrols - twin-scroll turbocharger, or turbocharger with fronted mechanical charger

Didn't realise that VeeDuB have progressed down that route
AND I thought our Smart Car's 3 cylinder, twin spark, turbo'd, intercooled, engine was technological........!
Perhaps I should get a water to air charge-cooler and air pump . . .

The 3 cylinder VW/ Seat engine has a mechanical supercharger or a twin scroll turbocharger. You said you wanted an electrical supercharger? It's the electric superchargers that don't work...

electric superchargers are possible, you can attach a turbo housing to an idustrial electric motor, and batterys, lots of. biger alternator. yes you'd get more bhp. however a lot of weight. doubt u'd increase bhp/ton, n cost a fortune.
agree Just get bigger lump.

They simply cannot generate anywhere near enough air volume/ pressure to work as a forced induction system.

If you think about it....

the 999cc engine is near as dam a swept volume of 1 litre.

So at 3000rpm (that's would be doing 60 mph in 5th gear)

you would need 3000 x 1 litter of air every minute

so if you want to raise the pressure above atmospheric pressure, your fan would need to pump more than 3001 litres per min

ain't it a lot of air

4000rpm (80mph) ....!!!!

 

[thunderbird2]

I don't have the slightest doubt that it works because I've already tasted it on the little VW.

The initial spool is electric (no doubt about this too) and then there's a progressive catch from the mechanical part. Very nice.

So, I want to do it to the Uno. First thing I'd like to know from you savvy guys is what kind of metering does the ECU rely on? MAP sensor?

And... as a side note, I was just watching the new 2 cylinder FIAT engine in the Geneva motor show that'll feature not less than 85HP Same approach.
