Hi Friends,
Just wanted to share an exhilarating experience I had on the Swift DDIs powered by the RACEDYNAMICS ECU (now available for
all DIESEL cars)
As we all know, the swift though powerful has a very narrow band of boost, as in one can feel a minute surge only from upwards of 2200 rpm to say a max of 3000 or 3200 rpm.
This often led me to wonder, is there a way by which I could somehow increase the performance and yet not have to take pains to upgrade the turbo and stuff. I always wanted to take the bigger cars and show some petrol’s what a diesel could do!
Last Friday, I got my answer.. A quick call to Karthik of Racedynamics as I knew that he had been working on a ECU for diesel cars and voila!, he just asked me to come over and then it all happened. A freind and I get going and reach Racedynamics and a brand new swift ddis (not even registered) get's operated by Dr. Karthik Reddy and out we go for a spin.
Boy oh boy! Trust me guys! Never really imagined the Swift DDiS could be this fast!! I mean, I already own a OHC Vtec and I know what fast and quick meant..but I wasn't expecting that from a Swift and that too from a diesel!!
The car felt quick right from the word go! With the boost kicking in at 2000rpm and carrying all the way till 4200rpm! The surge was just mind blowing! You just sink in the seats!!
Well! After being on tbhp from a long time and considering that I knew a cent or two about cars, I had something going in my mind, well all the cars would pull in the 1st and 2nd gear, the real test would be to see how the car performed in the 3rd and 4th gear right from say 1500 rpm.. Okay! The next thing I do is with Karthik a friend of mine and me (3 ppl), cruising in 3rd gear, I took it down till 1500 rpm and floored the accelerator, guys! Trust me on this! The performance just left me amazed.. I just that one thing to tell Karthik!! Dude! You rock!! All this while I was enjoying my vtec! Now it was time to get the Swift kicking some dust too!! Anyway carrying on! Slotting the car in 4th and then repeating the same gave me a similar feeling. The power was right there and the super duper surge from 2000 right till 4200 was mind numbing.
I am sure that you guys would be eager to see some figures like the 0-100 and stuff I don't have them off hand now! But will put them up soon or request Karthik to put it up!
But I have one thing that might give you a hint as to what we had on our hands! Check this out guys! Please don’t ask me the speed as I am aware that our car’s have a nice SPEEDO ERROR! Hence I concentrated on the Rpm meter!
A stock Swift DDis in 3rd gear goes from 2000rpm to 4000 rpm in 8.3 secs!
The same Swift DDis in 3rd gear with the ECU did 2000 to 4000 rpm in 7.2 secs!! A gain of 1.1 secs and that too in 3rd! just with the ECU!!
Heck this car didnt even have the plastics of the seats removed! And already it was a whole 1 second faster! Left me wondering what would happen after the installation of a K&N or a HKS filter!
I shall leave it to you guys to do the Maths!
All I can say is.. If you thought your diesel was fast!! You ain't felt anything at all!! Go and visit Dr. karthik and give your diesel a new life!
Cheers
