ever since the arrival of my swift VDi in september2009 , i have been constantly and steadily been personalising the car to my liking. below is the list of things i had done over these months.
1. 14" alloys (EVO-taiwan made)
2. Rear Spoiler(Swift Sport OE type)
3. underchassis neon lights
4. interior blue LED lighting-entire car
5. reverse parking sensor(with blue lights on the sensor dots!)
6. ICE-Pioneer 4190 DVD 1-din HU,Hertz component speakers on doors,12" Polk subwoofer, 1000W Rockford Fosgate mono amp for the sub and 500W Kenwood 4 channel amp for the door components, Caliber Wiring kit for the installation,Wurth sound damping for all the doors and Necvox roof monitor for watching movies.
7. Stanley Leather seats, incl. OE type steering cover.
8. a funky spinner gear knob(had to cut out the regular one and did some alterations to get the fitting right) and chrome exhaust tips.
9. 90/100 headlights.
10. skoda type horn.
11. Garmin Nuvi 715
12. door scuff plates with 'swift' in lights.
13. Llumar steel 35 sides and PP60 front sunfilms.
14. since the car had done 10200 kms already, i went for a complete OWS treatment(fully synthetic oil, engine protector, fuel treatment etc.)
15. last but not the least and perhaps the most important of all was the chip tuning from RACECHIP which was installed just a few hours back.
how the chip tuning works:
instead of conventional ones which remap the ECM or some kind of tampering with OE, this beauty plays around with only the fuel sending units. the wiring harness of RACECHIP slots itself between the 3 pin clip on the common rail unit and the OE wiring harness unit. this is then plugged into the RACECHIP box.
it was an amazing revelation of sorts when we plugged in the ECM scanner at the dealership and saw the readings appear.
1. in the idling position the standard ECM readouts(without RACECHIP) for fuel pressure/sending was between 5 to 7 cu.mm.this is the amount of fuel that is being sent to the engine during idling.
as the acceleration increases, the volume of fuel flow also increases from 5 to 7 to 9cu.mm and onwards.
now what RACECHIP does is, at start and idle it sends just 4 cu.mm of fuel, thus reducing fuel consumption at that time. however, when accelerating, the fuel sending unit pumps out much more rapidly from 7 cu.mm and above depending on the acceleration giving an amazing surge of power when needed.
Now when the foot is off the accelerator, the stock/normal ECM settings(without RACECHIP) STILL send out about 2 cu.mm to help the engine idle with minimum fuel flow, but with the RACECHIP on, the fuel flow drops to zero when the foot is off the accelerator, thus saving 2 cu.mm during EVERY deceleration! which is like more than hundred times in peak traffic time! so now i have the best of both worlds-my fuel consumption is reduced drastically in city traffic AND i also have a 25% power increase when i need it!!!
.
the only drawback, theoretically, i foresee is at long idling periods the aircon compressor might be experiencing a strain due to the lean fuel flow into the engine and hence a lower driving power to the compressor unit. this can however be eliminated by setting the thermostat to 22 degrees or higher to ensure compressor cut off to reduce compressor strain and save fuel as well.
i am planning on a long trip to maybe Yelagiri or Pondy to test out the full potential of the RACECHIP..so stay tuned for regular updates on this one!!!
