there are non mate. save ur money. its a well known fact within the UT boys that there isnt a chip available for a UT. even tho superchips say they do one, its worthless.

Dunc

Ok, so if Superchips doesn't do a chip, why is it on their page ?

Also, I have access to chiptuning software and there are drivers for the Uno Turbo, so there must be a way of remaping this ECU ? Since it's old, it can't be done via OBD, so it must be a chip right ?

Doesn't make sense that an old ecu like those ones wouldn't have an eprom...

Someone who knows the answer to this, please reply ! ;)

Thanks
 
The ECU in a uno turbo is a ROM (READ ONLY MEMORY) ECU as far as im aware.
It will only take its information from 3 sources on a pre-CAT mk2 engine (4 on a CAT model), throttle position switch, Air flow sensor and engine temp (lambda sensor on a CAT model) so any attempted chipping wont do a thing!

Someone told me that superchips just put a bleed valve on the compressor housing-to-acuator pipe!
BOOST SPIKE TIME!! lol

Its what over 20 year old technology now and they arent like what they are now!

Now most cars have "learn as you drive", ECUs these ECUs can be "Chipped" but all it does it move the Torque band around, you wont gain ****! lol

Its all marketing crap

The best way to get any improvement from ANY engine is to start from the ACTUAL engine itself!

Just dont belive all you read!

Sorry, but it is not all marketing crap.

Plus 20bhp resistors are! The sellers claim it will increase my carburetor Uno 45's power from 45bhp to over 60 bhp :p

On a serious note, I can't comment from experience on the Uno turbo ECU, but it seems that most people increase the power by the simple means of a dump valve rather than any fancy ECU re-programming.

What Biz says about the Uno turbo ECU makes sense, and seems to be the opinion of a lot of Uno turbo owners who've modified their cars. Perhaps if someone could explain WHAT a so called modified ECU for the turbo actually DOES to increase power with such limited information feedback from the engine (1985 technology here!), then the claims from some of the manufacturers could be believable.

I emphasise that I DON'T know exactly who is right or who is wrong, BUT, I've heard many turbo owners state that modified ECU's for the Uno turbo are a waste of time. The only exception to this, is when the power is drastically uprated and a piggy back ECU is installed to run a fifth injector for fuelling issues.

Anyone have any extra information on the turbo ECU?

my g-shock watch has more processing power than the turbo ecu.....

:devil: funny...

But really people, what about the last Uno Turbo's to come out in the middle 90's ? Won't those ECU's have more options/processing power ? :confused:

Cheers

so wat the best way 2 get power increases from these engines then?

How long have you got? lol

3 important things to go by while "Tuning" an engine.
(And i am a student but dont be fooled........the principles that i am now aware of are the same through out engine improvement!)

Volumetric efficiency
Thermal efficiency
mechanical efficiency

In short you want:

An engine that is as friction free as possible and that uses the strongest components possible but is depedant on the use of the engine
i.e. A N/A engine will need the lightest possible components to REV as high as possible because its N/A (F1 engine is the best example of this)
Where as a TURBO engine will need the strongest components possible due to the stress placed on them becasue of the boost produced by the turbo.

That can flow as much air that is physicly possible in to each cylinder with the minimum of disruption and effective turbulance and that can effectivly compress the mixture.

That can get rid of the heat generated of the rapid burning of the air/fuel mixture as quickly as possible.

Every aspect of tuning depends on what situation the engine is being used in!

It not easy at all, the thing that makes me laugh is that when i read that people put on a KnN filter and exhaust and think they can keep up with a skyline!

Little do they know that they are pravocing things to go wrong with their engines!

all the EXHAUST this and FILTER that is ALL marketing ********!
I just laugh at it all now. lol
 
In a lot of the race applications only a few sensor are used and these engines are running perfectly well. BTW you forgot at least one sensor that is vital for the engine to run, which is the rpm sensor.

From your bold statement about the marketing crap regarding induction and exhaust the only conclusion I can draw is that you are a studying theoretic that has got no clue what the meaning of an induction/manifold, a plenum chamber and an exhaust is. Neither you seem to know what is going on in an ECU. You are mentioning the VE on a given n/a engine is greatly affected by the design of the induction/manifild, the plenum, and exhaust and has to be designed in connection with the cam.

Nitrous Oxide injection, a bigger turbo, erm.... a bigger engine? :p

AFAIK nitrous oxide injection was first used on German Fw 190 fighters during WW2. Another tried and proven approach was MW (water/alcohol) injection, used on Bf 109 fighters.

Its implementation on Uno is described here:
http://www.fiat-uno-forever.de/Technik/waes.html

It supposedly increases engine output considerably for a short period of time by injecting the above mentioned MW mixture. It is necessary to increase boost pressure before it can be used on Uno.
Local Uno turbo has the article available in Czech, but when I asked about whether anybody tried it in real world, nobody answered.

As far as those KN filters are concerned, I never felt any desire to try them. My opinion is that they only very effectively prevent hot air from the exhaust manifold from getting to the carb during engine warm-up.
Local Renault club tested them and the results were simple - the only difference is that the car is noisier with them.
