Had been to a local car accessories outlet for helping out a friend accesorize his new Vento TDi (details here).
While I was waiting for the sales guy to be done with another customer, I saw a grey Swift DDIS outside, with the rear door open. I glanced in casually, and saw a box with a seemingly familiar logo and this made me take a closer look - it was the box of a
RaceDynamics piggyback
ECU.
This got me very very (very) excited as I had been trying to reach RD for the same, and seeing one such unit there meant that there was probably a dealer / fitter / tuner nearby! I searched around for the owner and literally grabbed him in my excitement. I didn't even realize that he was talking to someone on his phone (courtesy, manners and such other socially imposed behaviour go for a toss when pure instinct to try and get what you want kick in at full throttle). He had to explain to me that he was on the phone and would talk to me in a couple of minutes.
Well, I spent the next minute hovering around him and the car till he finally came over. I asked him about the ECU and asked him where he got it from - and guess what - he told me that he was the newly appointed representative for RD in Pune. That was like the cherry on top of the icing of the cake! (I think that I probably drooled right there, and the excitement on my face was probably visible, because the guy broke into a grin). I was like a kid who had just got his first bicycle (or probably the address to the bike shop with the new shiny bicycle).
The guy realized that I did not need an introduction to the ECU and asked me if I wanted to take the test drive. (
Neki aur poochh poochh??). I had said a yes before he completed the sentence - and then realized that his ride was already modded. So before the test drive, I asked him to pop the hood of his Swift. Checked the DieselTronicPro piggyback ECU. It was pretty compact. One cable was going to the battery, another 2 to the ECU.
Quickly checked the feasibility and realized that I could fit it in myself.
Before even taking the test drive I asked him if I could get my Optra there and whether he would be able to change the necessary settings and TD my Optra instead.
He said that he did not have the corresponding maps or the connectors for that matter, so I had no option but to go in for the Swift test.
Before describing how the test went, here are a few details about the DT.
--------------------------------
The unit fits under the hood without altering any wiring. Has the necessary connectors and is a perfect plugin and sits between the ECU and the wiring going out from the ECU. It has 4 modes as follows :
- Stock - Works as per the stock map (probably something like a bypass mode, returning the actual stock values from the ECU)
- Economy - Reduces the power and torque and increases the FE (claimed to be upto 40%) - to be used when you give the car to your wife or dad
- P1 - Power 1 mode. This is similar to what the regular ECU remaps return. About 20-30% increased torque and power. No idea about the FE. - for you when you want a power ride
- P2 - Power 2 mode (AKA Crazy mode - AKA Clutch plate destroyer mode - AKA Tyre Burner Mode). - for you when you have or want a adrenaline rush, and also a lot of money to change your clutch plates and tyres!
Now the best part - To switch between these modes, all you need is the remote control and you can switch between these modes ON THE FLY - no stopping the vehicle, no getting out!
---------------------------------------
So, I got into the car, he took the car out to an open stretch. Initially he put the car in
Stock mode. The car was OK. I wasn't doing any comparisons with the Optra, so will not bother telling the difference.
Drove for a bit. Then he put the vehicle into
Economy mode. The pickup and the power dropped, could feel the same - had no way to check the economy. Drove around for a bit, had it put back into stock mode, and then after a bit, into
P1.
The feeling was awesome. The extra torque and power was felt. (Actually I got so engrossed speeding about, that I forgot to see the max revvs and the speed). Also, keeping the car at about 1000-1200 rpms, I could easily shift upto the 5th gear without the engine stalling or even knocking for that matter. (So fitted on the Optra, that should take care of the turbo lag!). This was good, and now was the time to get to P2.
For
P2, I stopped the vehicle and started from a standstill!. Put the vehicle into P2 mode, slotted to first, released the clutch and stepped on the accelerator, and before I could feel any movement, I heard the wheels spinning on the spot, smelt some rubber burning, I was thrown back, and we had lightspeed!! (well not exactly - you would need to have the Optra for the true Warp Zone effect and to reach lightspeed
). But seriously, the P2 mode is overkill - in my opinion, to be used only when you have stiffened suspensions at the least!
Got back with a lot of adrenaline rushing in, exchanged details with the rep and he has promised me another test soon. I am getting this fitted in asap (after first servicing at 5K)
All this while my poor friend was waiting at the accessories shop wondering where I had disappeared all of a sudden. Tried to explain him all this, and was also trying to convince him to get this fitted in his new Vento TDi, when he told me that he hardly crossed 80kph
!!
So started the activity to explain to him what a turbo is, how the effect is felt and so on (which basically meant a test drive of his brand new Vento). See
this for that story!
All in all, it was a fruitful Saturday!
