Engine Tuning for Swift VXI for better FE
Hi,I purchased my first petrol car - Swift VXI 1 week ago and I LOOOVE this car's feel and response (compared to other petrol cars too). My previous car was an Indica DLS and it used to give me a mileage of 15-16KMPL in bangalore peak hour traffic conditions.
Now since my new car is much powerful than the old one and runs on Petrol.
I have 2 issues.
1. I have enormous power and low mileage
2. High cost of fuel that relates to Low mileage.
Apart from optimum driving conditions and practices I would like to know if there are any modifications that can be done to improve FE without affecting the power and the warranty from MUL.
I've heard from a friend that there is a workshop in Kormangala Bangalore where a guy who used to be a Rally driver is into tuning engines and is a specialist in Swift engines.
If any of you know this guy I would love to get some reviews on this guy and his service. Since its a new car I'm a little sceptic in letting unknown people get their hands in the hood.

Try changing your driving style.
I have seen that Swift get more kpl when driven at high speeds on highway. In city you will need to rev it to keep it moving as it has bad low end torgue.
Better air filter and header job should help increase low end grunt.

After being used to a diesel the cost of driving on petrol must be really shocking!
I too feel that tuning is not the answer. Make your driving as utterly boring as you can: that's the way to spend less on fuel!

Its just one week right ? and assuming that its a new car, give it some time like till 2nd service is over so you can actually comment about the FE.
In a new car the FE will the low, new parts more friction something like that...
How much is you FE now ?
If its a new car, let it "run-in" and then if you feel its bad look into it.
As its suggested here,
1. Changing driving style
2. After market air filter
3. Slight over inflation of tyres (not recommended in wet)
4. Switching off engine at lights.
5. Not running A/C at full blast.
6. Headers (Yup anything which increases efficiency in theory should improve FE)
I don't think its really fair to comment about the mileage of a brand new car that has not even been serviced.

Do not get swayed by any marketing content that claims to be a miracle cure for mileage. The only thing they would probably end up doing is to ruin your engine in the long term and leave you feeling silly about that purchase later on.
Also, since you've only just got the car, defer judgement till the 2nd service after which the mileage would have picked up.
Everything does finally depend on how you run it in, how well you maintain it and your driving style.

If FE is your aim, there simply isn't a modification or tune job that is as effective as a conservative driving style. Please read our article on FE (ARTICLE: How to get the maximum Fuel Efficiency) to extract the most FE of your car.

If you are comparing the mileage with a diesel car, a diesel in inherently efficient engine, By the way what figure are you getting on the petrol swift.Let it run in properly first than look into the efficiency part of the engine.
Also it is hard to get use to the difference in prices of petrol and diesel fuel, and since you have been using an Indica that will be the main reason that you feel the mileage is low..when you go to a fuel station. as you pay more per km for the same distance covered in the old [diesel] car and the new [petrol] car.

Some of the ways to improve FE that I can think of -
1. Use large diameter low profile narrow tyres for improving FE. However it will reduce the low end torque further.
2. Make the body more aero-dynamic, remove ORVMs (many people in Hyderabad do that).
3. Stiffen up the suspension
4. Reduce car weight by removing back seats, spare tyre etc.
5. Keep mimimum fuel. Full tank means an extra 30-40 kgs.
6. Use parking lights instead of headlights if street lights are bright
7. Reduce idling rpm
