Hello everyone!

My car is Seicento 2003 MPI and I finally plans to install turbokit

I'm wondering if I need to change my car computer or will he learn new information?

This is my precious turbocharger

You will need to do a lot more reading and research both on this forum and elsewhere

Yes you will an aftermarket ECU will be needed either standalone (megasquirt etc) or piggyback (det3). You'll need either a resistor or fcd so that the current map doesn't have a fit over seeing boost

What boost level are you planning?

I would ditch the standard plastic inlet and use a punto 75 or palio inlet and fuel and tb it'll need some work to accept the mpi map sensor but you'll have far greater choice of injectors (youll need to change)and they flow far better.

Also an oil cooler is highly recommended rest of the car needs to be top notch so good coolant syatem, brakes,suspension etc

For some time I read a lot of topics and I have found a very different information. Someone says that you do not need an aftermarket ECU (the computer will learn), some say that the turbo can not well be installed on the MPI engines ...

My car is in excellent condition and is ready to turbo conversion:

- 14 "wheels, 185/50 tires
- 2cm spacers
- Improved brakes
- Sport exhaust
- 40mm TB
- STRUT BRACE BAR
- Complete Novitec turbokit in good condition (5 PSI turbocharger, intercooler, pipes ...)

The biggest problem is my ECU unit, resistor and changing injectors.
I do not understand anything

Is there to buy already programmed ECU?

Any help means

You really ought to do your homework here, the mechanical bits is only a small part of a successful turbo project.

There are ECUs / setups that will deal with very modest boost levels (the ECUs that have a slightly over atmospheric MAP sensor), but I mean like 0.3 bar tops, which is nothing. And even though they'd deal with it, it would be far from optimal and perhaps unsafe. And 1.1 MPI ECUs are not in this class anyhow.

The Novitec setup came with a piggy back controller and/or modified stock ECU, but that was for the SPI setup, MPI is technological ages from that. You are looking at either hooking it up with the DET3 piggyback or an entire aftermarket system. Both solutions should be able to deal with replaced injectors (in case of DET3 by using fuel implant mode and disconnecting them from the factory ECU, which would otherwise freak out).

I am not proposing the third option, as it is not an off the shelf one - I did actually make a turbo version of the 1.1 MPI ECU, but only the big one (not the micro ECU), see here:

and at posts from roughly a year ago in my thread:

https://www.fiatforum.com/cinquecento-seicento/216652-wojs-turbo-project.html

It was working, but I did not manage to make a stable all purpose map for it, and now the car is gone.

My thread should also tell you about what you look at in terms of engine control and you should really read up on things. Properly done it is a difference between having an all time reliable turbo setup and going bang on the first day

Give these people a look.....

Thanks guys. I did my homework

I have another question, when I install DET3 can I remove the cat? (2 lambda sensors)

you can remove the cat whenever you want. Just install a cat fooler on the second lambda. Is nothing more than a spacer that will reduce the amount of gas on the second sensor. Google it

Cat fooler works well

Which smaller intercooler can i use for my Turbo conversion?

Punto 1,3 MJT maybe?

I had a car accident and my turbo project is on hold

The turbo project will soon be completed, for now is 102HP


Special thanks to woj and The Black Box!

Nice!

You are welcome

For a 1.1 MPI engine and moderate boost level (what is it BTW?) this is a nice result. 1.1 MPI inlet and valve are quite restrictive, forcing almost another 50hp on top of the factory 54 is not that easy.

Turbo boost is 0.9 bar (about 14 PSI). Turbo Charger starts to kick at 4000 rpm

What oil is best for turbo seicentos?
Selenia K Pure energy 5W40 or thicker ?
