Re: Volkswagen Vento : Test Drive & Review I have wanted to post this for some time. This is just an appreciation for a job well done and some information for my fellow BHP-ians. I hope it's useful
I bought my Vento TDi in Feb 2012 and with extended warranty just for some peace of mind. I was really enjoying the power and torque of the 1.6 TDi. However, after the first service, I found the performance of the engine to have become some what muted. I had written about this on the forum also back then. Having extended warranty, I did not want to do anything and continued to drive my car in stock form.
But the desire for little more power kept creeping up and I started toying with the idea of performance tuning since last year. I did not want to jeopardize the warranty and neither did I want someone experimenting with my car. I heard about diesel tuning boxes and read up all that there is to read on our forum and certain other places on the net. I also considered re-mapping. I understand the latter's inherent advantages. However, I wanted a solution for my vehicle which was hard to trace/removable and customizable as per my needs. Not that the Vento screams for tuning. Let me be clear. I like it a lot. I wanted to maintain its stock character with an option to change to performance mode whenever I desire. The Vento’s stock performance just required some touch-ups, all this without blowing its engine, seizing it’s turbo or leaving a exhaust smoke screen behind.
I spoke to some Tuners and visited a few for demos. Lot of the tuning boxes gave me punchy performance and some came with 2-3 different maps too. I was impressed and I liked the way those boxes performed but none of them convinced me enough to put my money on them.
One of the tuners I met was EngineCAL. It seemed a sincere and clear explanation from the start. Their ‘Add-On Module’ or MECU, as they call it, certainly did not blow the competition away, yet in longer cogs felt somewhat more torquey. EngineCAL was quite clear that I finish running-in and get the oil change before they consider any tuning work. Since my first service was already done, they agreed to work on my car. Though I understood that their unit too was a Tuning Box, it certainly was not something they simply plug-in and ask you to drive. The best part was that I got to say how I wanted the Program/Map in their Unit to feel. It was a full two hour drive during which the Map was being fine-tuned constantly based on my inputs. I quite enjoyed myself. They were connected to the Module in the engine bay via a programming device and double-checked the values on a laptop with a tool developed by them for checking peak fuel pressures. It turns out that they had a data-base of fuel pressure maps of several cars against which they would compare the Map being tweaked in the MECU. Interestingly, all this was on-the-fly while we were driving on the highway. I think they call it real-time calibration.
It appeared to me that though their device supports a high degree of tuning flexibility, it was the gentlemen themselves who provided the edge to the tuning solution with a good amount of effort and knowledge to build Maps for several different cars taking into consideration design limits and smoke levels. I was pleasantly surprised when they followed me in their vehicle to check the increase in exhaust smoke when we did a quick run with the Unit switched-on versus off. In fact they did one more round of mild tuning after that. It was later that I came to know that they work as consultants to car & component manufacturers. Both gentlemen were ex-employees of a German OEM.
Its been about 5,000 kms since then and no Lamps and Chimes. The first Map they made for my driving style was very mild. Only over the next 1000 kms or so and over a few “calibration meets” did they increase the torque and finally bring it to the current level. Still, not quite as crazy as some of the others.
At the point of making my final decision I wondered if having an extra Map or two like certain other Tuning Boxes would have been advantageous. The thought of shuffling through different modes did feel kind of cool but I was looking for one dedicated, safe and custom developed Map for my driving style. Also, the engine reliability part stuck in my mind. Finally, their personal involvement and attention to detail helped me make my decision
Their seriousness towards engine reliability was evident from their explanations and the way they went about their job. They also gave clear cut instructions on their control unit's usage. One of the instructions which I appreciate the most is to switch to performance mode only after driving for a few kms for engine warm up. Putting me on their mailing list about the dos and don’ts for engine upkeep, which I observed had been updated every year, was a nice touch too.
I will post about the Vehicles performance and fuel consumption from time to time.
