VW software update: at 61595 kms
Decision to perform petes remap forced me to perform this, just to make the car clean in VW records and that they don’t perform any software update after the remap is done.
Performance after software update: Unfortunately, I cant write that word in such a highly decorated forum, but you can guess that. As told by many, yes the car drives better in city. If you are one of those relaxed and sedate type, you would not feel the difference for sure. For jetta engine lovers, the mid range and top-end punch is now a distant dream. The engine becomes noisy and will beg you not to push harder and further. The drive which used to feel like gliding on that expressway at triple digit speeds is totally gone. You have to keep the pedal pressed to drive at those speeds, previously I have to control the pedal so it doesn’t go any higher that my sweet spot. That’s the difference. In my experience fuel economy is also compromised, especially for those enthusiast drives.
Petes remapathon:
I knew the guy from petes was coming to Mumbai and hence I kept pushing him to make it to Ahmedabad. Unfortunately, he had some other commitment and hence he proposed to send the ecu to Mumbai instead of cochi. He was visiting on 3rd jan and he confirmed the bad news of not coming to Ahmedabad on Friday. So I went for VW software update on 31 dec, 2016, the last day of the year, considering new year will bring happiness. It was Monday morning that I learned that one of my colleague is going to Mumbai and thought about handing over the ECU to him. But office is in Baroda and car is in Ahmedabad. Then I thought why can’t I fly by myself, (interesting, see how things turn up), take all the 3 ECUs and get the job done same day. Then I gave that option a serious thought and decided to bunk a few meetings. It will now be an unplanned leave. Then I spoke to tanvir in Mumbai, and he gave my thinking a twist. Why cant I drive down to petes in Mumbai, its just 550 kms, the advantage, I can test the car then and there and incase something arises, we can sort out. By 5 pm I finalized to drive down to Mumbai myself and get this done. My first drive to Mumbai and have no idea about traffic after vapi, but decided to negotiate that when it comes.
I started at 4:20 in morning and reached petes at 12:30, The guy (Vinu) was already there and started working on one of the three ECUs I brought with me. Rishad (The owner of performance unlimited) upon my insistent showed me how it is done for a couple of minutes and I have to admit, it felt like a bypass surgery of your heart (it was for my car’s heart for sure). No vibrations are allowed on table while vinu does the calibration. I have to say it was not just a software update, that I thought it was. I was like you simply cut my OEM map, cope one of the higher tuned cars and paste it in my ECU and job is done. But I was wrong. I was impressed as well.
Finally, mine got done around 6 p.m. and it was time to check if car starts and it works. They fit it back, and turn the ignition and voilaaa. Engine came to life. It was now when I felt a sigh of relief. It was time for a test drive on marine drive. Rishad took the driver seat and I belted myself in passenger seat probably for the first time in my life. He saw an open stretch and pushed it full, wheels spin and engine is revving at 4000 rpm, felt scary but in a nice way.
POST REMAP PERFORMANCE:
I had to reach my office in Baroda next day and hence I started from Mumbai at 9 (waited for the traffic to ease). Reached dahisar and crossed the infamous vasai-virar bridge around 10:30 p.m.
I was really tired after 8 hrs drive and then 1.5 hrs in Mumbai traffic, peddar road to dahisar. But trust me I never knew when that 1.5 hrs passed. The drivability is so improved that even in slow moving traffic I didn’t feel stressed out or tiredness. May be because it was the first day.
Followed T-bhp night drive guide and Checked-in to Kings resort and slept. Tomorrow is gonna be a good good day.
Started from Kings resort at 6 a.m. let it worm up for 5-6 kms and then for the first time floored the pedal in 3rd. In a matter of seconds she was 120. Engine is so free revving now and car begs me push harder and harder. Amazing amazing amazing. Now it was time to test my usual driving style and push off from there. So I let her roll at 100 110 for about 1.5 kms and then saw an open stretch and floored the pedal in 6th gear itself, to check the response after remap. Oh boy, there was a push which I can feel and a second of shudder (gearbox or tires vibrate) and then she flies off without any fuss. Similar story for 5th as well but rest four are without any issues. Just one word WOW.
I informed this behaviour to vinu and he says ECU will adjust according to my driving style in about 1000 kms. It’s the gearbox not able to digest the torque and power eventhough mine is manual.
