In VST,They have the Fiat scanner for checking the whole car.
Even i too checked it personally.

I service my Palio MJD at Prerana Motors, OMR, Bangalore. I remove the box before setting out to the service station, and refit it after I get the car back. I have had a defective turbo changed under warranty - and they went through the ECU read-out with a fine toothed comb before approving the change under warranty. But no sweat - obviously any incriminating lines of code about the box were missing.

ICE - that is very reassuring statement that you have made. Since you are using the Petes box, could you write your experience with the box and how much of a difference it has made to your Palio MJD post the box.

wouldn't that remove any signs of a tuning box from the ecu?

When you disconnect the battery for a short while all you loose is the long term fuel trim, which is the larning capability of the ECU.

The data logger has to be cleared, which you can't even do with an examiner.

thank you cph.

ice,you've put me in a mess. I'm still unsure,does a pete's box register or not?

Ice, do you remember the cost of the turbo from the bill ? Also, what was the labor amount ?

I understand it was covered under warranty but was keen on knowing the costs.

Why do a lot of Pete'd cars have blown turbo problems? I have rarely seen a properly maintained and driven stock car with turbo problems.

Rich mixtures emanate a lot of unburnt fossil fuel in the form of black smoke. This carbon ends up in the turbine housing and the bearings of the turbo unit. Rest is easy to figure. Carbon build up messes with lubrication and heat dissipation. In addition to that FIAT/TATA and Maruti are using the cheapest aggregates as far as the turbo unit is concerned. If your tuning box does not control the airflow in addition to fuel flow do not touch it with a barge pole.

+1.
Well said Pullockaran.Pete's boxes work on the principle of just dumping in more fuel leading to a richer air-fuel mixture. I have not personally used a Pete"s box myself, but its a widely accepted fact that a remap is the better option, for extracting enhanced performance from a crdi turbo diesel engine if u do not want to have smoking issues under load.

I do agree with you apart from the point you made regarding the turbos.

The petrol ones are IHIs, which we have mapped in Europe and had no problems for some of them now having done 70k since mapping.

The Diesels use Garrets, which were fine apart from on batch that went wrong, but Volkswagen got units fromt the same batch showing the same problems.

[sdp1975]

So fiat uses garret in Europe ? In india I believe maruti ( and even Fiat ? ) uses KKK turbochargers.

Dear CPH,
I am sure in the petrols that you chipped/mapped you did not allow the mixture to become richer than 11:1 air is to petrol ratio.

Diesel engines turbo is more susceptible to soot build up because of the very nature of the fuel and its burning characteristics.

I am not doubting your acumen though. You have succeeded because you used the best aggregates. In India in the name of cost cutting the price of the turbo used in the first batch of Palio mjd used to cost 53000 indian rupees and the present batch with the 1.3mjd engine used in many Indian cars costs just 16000 rupees. Its easy to figure out why the present day turbos konk out so soon. Also note my deductions could be totally wrong since I am an Orthodontist by profession and electricals/mechanicals and electronics is just my hobby.

i think partly its because it was imported before but now its made in india.
btw even the DDIS turbo costs around 20k

I am not too sure whether you have to blame the quality of the turbo charger rather than the people who try to supply a lower grade of Diesel (not removing certan substances because it is more profitable) and the people mapping the Diesel.

We have a lot of so called re-mappers I wouldn't even touch with a barge pole because they are mapping totally wrong, which results in smake and now it is getting even worse because of the DPF you can't see their 'handy work'.

I would like to see one of the blown turbos and compare it to the ones over here.

The engines are the same only the mapping and probably the turbo unit is different. By the way the quote for Rs16000/- was for the 1.3 FIAT diesel engine in the Swift. Ripper changed his turbo in his Swift but this time he got a propah turbo from Peter for about Rs53000( he got it free though) and that unit is working fine in his hyper tuned FIAT engine. The turbo used in the FIAT engine for the Vista, Dezire and the Punto/Linea is about Rs23000
