Review : Wolfmoto Switchable Remap I have been driving a Linea MJD since three years now. Have done lots of DIYs and permutation combinations of oils and have taken utmost care of my car. Fiat India has always helped me smile with the amazing service they have given me over the period of ownership. I mostly drive in the city with a daily commute of 60 kms. I have always loved the linea in stock form too , but the city drivability is the questionable area for many when it comes to Fiat Multijets, Punto and the Linea. True – The 1st and 2nd gears are short, before the exhaust gases build up enough to give a full spool to the turbo we are forced to change gear or sometimes hit the brake again and back to square one. This gives a feeling of lag, even if the engine revs nothing revolutionary happens and this is kind of irritating when you are on the boil to reach your destination as soon as possible. Over the period I tested few tuning boxes – I wont name any, please, I don’t want controversies, to overcome the above problem. I got good power and push in the upper ends of the revs, but to be frank I hated the car more with tuning boxes. Reason – drivability was hampered totally and secondly my 10% of the so called knowledge in the automobiles and technical areas were ringing alarms in my mind and heart too that the working of tuning boxes is not even 1% correct. Tuning boxes just drop the voltages across the common rail sensor to fool ECU to supply more fuel. The second type of tuning boxes fool both Rail pressure sensor as well as MAP sensor. The whole idea of tuning boxes is to fool and fool. But these manufacturers rob our money to build cheap resistors and cheap IC based boxes which cost peanuts to manufacture, but they cost us a bomb. I am not saying this based on just on hands experience, but I have enough substantial proofs after extensive logging to showcase that the factory parameters are exceeded which is harmful to the engines. I know some people might debate that I have run lacs of kms with boxes and nothing happened to my car etc etc. but then I would just say that they have a goodluck. Ok coming back to the topic one fine day thanks to Mathew Josephs, I saw a facebook post of switchable remaps. I dint read further on how the driving experience was etc etc. I just mailed the Wolfteam guys with some simple questions. To my surprise I got a quick reply and I was amazed to see perfect answers to all my questions that too 100% technically correct. Most of the tuners ( I wont mention names) failed this very basic test and gave me vague buttery answers which I would never buy. If there is something fishy I sense it immediately. I start hearing noises “ Gol maal hai bhai gol maal hai” :evilsmile Then I replied them back with few more questions about the switch etc. Immediately I received a call from Aadarsh who is the implementing partner with Rajiv who is the main brain behind all this who cracked the concept of switchable maps. More about Rajiv later on. You can read about him in one more thread http://www.teamfiat.co.in/engine-dr...ecu-remaps-wolf-performance-tuning-my-gp.html I bombarded Aadarsh with detail technical questions and requirements after which he said “Hold on Amit, better you speak to Rajiv directly “ Before I could call Rajiv I got a call from him. We had a talk for about 1 hour and the best thing I immediately noticed about Rajiv was his transparency. He never intended to do this commercially. It was just his passion and utilization of free time to explore the ECUs, maps and other stuffs. He did all this as a part of DIY on his Skoda 1.8 TSI. Then he did it on Aadarsh’s swift and then it kind of went viral. From my talks with Rajiv I found out that he is technically very sound, a patient listener and welcome to ideas and information from others. Only a down to earth person with Zero ego does this. He respects other tuners, doesn’t utter a single bad word about them and refrains from commenting on their work too. By now I had a very good experience on the MJD engines due to all the investigations and DIY I keep doing so I shared a few critical points on the MJD and especially the working of the VGT loop on the linea and punto90 hp. Rajiv promised me to take care of all the things I was very particular about, not only the performance but mainly the drivability and safety of the engine. Meanwhile I discussed this on our Pune TFI members group. Enthusiasts jumped out of their pants and wanted this immediately. They were banking upon me. If I approve it they approve it. So this built up a lot of pressure on me. I dint want people to screw me later on that because of me they did it and things got messed up. So we lined up few cars and asked the Wolf Team to come over. Immediately within 2 days they started off from Kochi, drove non stop full night for 22 hours and reached pune. Without any rest they started work on my car first with other people watching us with excitement and curiosity with eyes wide open and ambiguity in mind. The first read on my linea failed, we all got a bit nervous, but soon realized that it was the laptop issue. Rajiv took out the ECU and then hooked it to his BDM rig and took the read in flat 2 minutes. He immediately pushed the changes, the switchable maps while I was seeing his work. We connected the ECU and checked if the switches of the maps was working properly in the standstill car. Then we cranked the engine and realized all was fine. I took the car on a good spin with the ECU scanned hooked in to ensure that the max rail pressure and the boost set by factory do not exceed. I was immediately impressed with the smoothness, the low turbo lag and the way the car was responding to just small taps on the accelerator. One this immediately came to my mind “ Now that’s what I call a performance” I dint show much joy to Rajiv who was sitting in the co-driver’s seat with laptop. I kept revving to max, changing gear and ripping to max and kept asking the values to Rajiv. This was with full five people on board and with AC on. This was the worst case testing scenario. Not even a single time, I repeat not even a single time the rail pressure and other critical parameters went above the factory limits. Wow, I am enjoying power without worrying about the health and safety of the engine now. Even if the factory limits are not crossed I am very particular about the EGT( Exhaust Gas Temperature). We have no equipment to test this currently, so in the most powerful map tuner has recommended not to keep the accelerator floored for more than 30-40 seconds on expressway at high rpms. We are planning to log the EGT as well when my equipment arrives. We also don’t know how much is the increase in BHP or how much is the increase in the Torque. But my BUTT Dyno says there is good amount of increase. Well for me the figures don’t matter at all. What I emphasize upon is the performance, the drivability and the safety of the engine. A tuning box claims 112 bhp and 240nm torque. But the drivability sucks on them and then way the power comes is totally rubbish. The very most important thing which we wanted was to delete the EGR, the EGR causes lots of soot inside the intake. Till date no tuner was confident that he can completely shut the EGR on Linea. According to them they tried doing that and errors cropped up after driving 20-25 kms. The next flash that Rajiv did on my car was with EGR deleted. While the other cars were remapped I took my car for a long drive to check if error comes up. In 63 kms of testing I dint get any sort of error. This was the most happiest moment in the whole exercise. I congratulated Rajiv for cracking this one. Meanwhile Punto 75 hp was ready for testing. God we were totally shocked to see the 75 hp transform into such a mean machine. The lag is gone, car behaves like VGT and climbs the flyovers with full load in 5[SUP]th[/SUP] gear. The throttle response is so good. I started loving Punto more than my linea. Agile and quick. While doing all this we faced a biggest road block. The 2009 model punto code happened to be totally different than other puntos. All our cars has 2.5 mb file and the old puntos have just 512kb file. The owners of these cars felt very depressed after hearing that we cant remap these cars – period. But Rajiv is such a gem of a person, he took the ECU out and worked on it continuously for 20 hours without sleep and finally cracked the code and put the switchable maps on the older punto as well. He had to rewrite the entire code, entire logic for this old ECU under tremendous pressure to deliver. I have lost the count how many times he smoked and had coffee to ease out the pressure. At the end it was effort well paid. We did 6 cars in total and all the guys are damn happy with what they got. I am happy that my Linea got a new life. Sorry 5 new lives to play with. Best part of the remap – stock remains. Icing on the cake – the no of programming counter remains same and the remap is untraceable. Coming back to the Switchable maps here is what we got. Map 1. Stock mode. Map 2. Economy mode. Acts like stock in lower ends, car doesn’t pull to top end ( good as valet mode or to make your friends and relatives to drive your car in this mode J) Map 3. City mode, less lag moderate power, efficiency not reduced, drivability vastly improved Map 4. City Highway mode, good power, zippy, builds revs quickly, minimal gear changes required, smooth – this is my favorite map Map 5. High power – crazy mode, MJD turns into a beast. This is for the racer boys. I bet no similar segment car can beat you in this. This map comes with few warnings from the tuner. There is a shift on fly with got along with the above 5 maps. As soon as you hit 4100 rpm in any but stock map you directly jump to the most powerful map. This is a very handy feature when you want to race anyone or overtake in a zippy. I have given further requirements to Rajiv to enable map changes while the engine is on via some of the Canbus buttons. He will be looking into this. I want to sincerely thanks WOLFMOTO Team, Rajiv, his brother Haari and Aadarsh for working with us day and night without hesitation. I will be doing an extensive testing of all the maps with hitech devices once I get them. For any changes Rajiv is very much open to make them in next trip. I wish them all the best for future endeavors.
