Finally, My Grand I10 is remapped by Tune O Tronics.



November 2015 :

I had planned to remap grand i10. I contacted few tuners regarding the same.

TOT :

Me : Hello, I wish to remap my grand i10 diesel. What is the price? Have you remapped the car before?

Vivek : We can remap grand i10. But we have not done it before. It can be done. Price is 28K

Me : Thanks, I will get back to you

Code 6 :

Me : Hello, I wish to remap my grand i10 diesel. What is the price? Have you remapped the car before?

Sajan : Yes, we have done grand i10 remap before. Car is doing really good post remap. We can take it up to 100 bhp. It would cost you just 24K.

I decided to go with Code 6 as they claimed to have remapped grand i10 before and cost was little less than TOT.

But it turned out to be one horrible experience.

February 2016 :

I thought of getting a tuning box from RD since Code 6 remap did not make any power. RD guys are really professional. They sent me a single channel box for trial. I drove for few days and ended up buying the box.

I was happy because there was power gain. But as I drove more, I realised power delivery is not across the entire revv band. There was good difference only between 1800-2500 RPM. Low and top end was almost like stock. A remap can make the torque hold for longer revv band.

July 2016 :

I decided to give remap another shot. I have a Wolf remapped SX4. Wolf tuner works in ship and was out of country. So I decided to contact TOT.

Me : Hello, I want to remap my grand i10. I had contacted you earlier, but decided to remap from another tuner and it did not work out well.

Vivek : Yes, I have read about your thread in Team-Bhp. I still say we have not remapped any grand i10 before. But we can definitely give it a shot. You would be the best person to judge about the car post remap

Me : Sure, let's fix a date and place for remap.

Vivek : Done!!

August 2016 :

I met Vivek in Bangalore. We drove to some deserted area. Road is closed for public here. So it was safe to do all tests with their VBOX.

I mentioned very clearly that I am not behind numbers. I just need good in gear acceleration. Grand i10 has good low end even in stock map and good driveability. I just wanted punchy mid range and little more juice at top end. My requirements were discussed with Sid.

Vivek did not waste time and opened hood to have a look at ECU and Turbo (Code 6 tuner had not even bothered to check). Sid asked Vivek to send snap of Injectors too. It was Delphi injection system.

Vivek said turbo is FGT for sure. There is no electronic solenoid here. Boost increase is possible only with a manual boost controller. It cannot be done with remap. ECU is Delphi make : DCM 3.7. It's the same ECU used in I20.

Vivek read the map file using OBD port. Reading of map file took around 15 minutes. Vivek emailed the file to Sid. Sid made necessary changes. A lot of parameters were changed and made to work in harmony with each other. This is what TOT calls as "clean burn=no black smoke". Sid sent the remapped file in 1 hour. Vivek flashed the new file through OBD port. Writing of new map took just 10 minutes.

Now it's the time to put the car under test. I was not expecting much because of my previous experience with Code 6 map which hardly made any power gain.

Depressed the clutch pedal , pressed push start button and the engine fired like before. I was little tensed and was just hoping this remap experience would be fruitful. To my surprise, this happened to be the best remap. Car was pulling really well. There was no lag, mid range was very punchy and even top end had little more juice. I was so excited and started screaming "Yeah, Grand i10 is finally remapped and making good power too". Also there was no black smoke even under hard acceleration. Car was revving freely and it just felt like I am driving a totally different car. Vivek had got Vbox. We tested the car on both stock map and TOT map. I was very impressed with the difference.

We decided to go for lunch. Also Vivek said Sid will give an updated tune if required later. Now sid sends an updated file. I was excited to hear about this. Vivek flashed the new map and I go for a drive. This new map was just insane. Car was picking up speeds so easily. It was more free revving and engine sounded butter smooth. I never expected my car to transform like this.

Grand I10 has only 3 cylinders and 1.1 litre engine. Still TOT map made a significant difference. It feels like TOT added one extra cylinder . I can now imagine how tune friendly bigger torquey diesel engines would respond to TOT remap ( like my 1.6 S-Cross)

I was very happy with remap. But I was super happy when I drove more. ECU got adapted to new map and car felt more faster. It never felt like a 3 cylinder diesel engine. I was able to hit 3 digit speeds easily. Car used to struggle above 120 KMPH in stock map. I have not noticed any difference in top speed. It's all about good acceleration post remap. I always had to downshift to overtake in stock map. Now with TOT map, just press the throttle and car will pick up speeds very easily. Grand i10 has good driveability in city and TOT map has totally transformed the car on highways. It feels so easy to cruise at good speeds post remap. I will get a dyno run if possible. TOT recommends to get it done at Coimbatore.

V Box timing : 0-100 KMPH

Stock : 16.2 Sec

TOT Map 1 : 14.9 sec

We couldn't test the timing in TOT map 2. I am very sure it is faster. It should be in mid 13 sec.

Estimated figures post Remap :

Power : 90 PS
Torque : 200 NM

My observations after trying out Code 6 remap, RD box and TOT remap in Grand I10 Diesel.

Code 6 :

1. Knowledge levels are questionable. Trial and Error methods to remap.
2. Not ready to accept any mistake or apologise.
3. False high power and torque gain numbers.

RD :

1. A bunch of professional guys and very supportive
2. RD single channel box alters only fuel rail pressure. Yes, it has power gain (but not across the entire revv band)
3. Plug & Play, Easy installation and No warranty issues.

TOT :

1. These guys really know what they are doing.
2. One of the most experienced tuner in the country.
3. They tell stuff honestly and no cheap strategies in business.
4. TOT map made good power even for a puny 3 cylinder Korean engine.

I should have got the TOT map at beginning itself. I could have saved time and money. But, overall learnt a lot dealing with an arrogant code 6 tuner, professional RD guys and "The Remap Specialists : TOT". What matters is the experience of a tuner. Sid used to work for tuning houses in USA and very experienced.

After I posted about Code 6 experience in various forums, Sajan Thomas claimed nobody has developed a good tune for Grand I10 in India. Well, there is a really good map from TOT now and Yeah they took hardly one hour to do this.

Anybody can dance.. Well, Anybody can be a tuner. It's not at all difficult.

1. Get online training from European tuners for few days.

2. Buy some basic tuning equipment, start a website and make sure some reviews are put up in social media.

3. Most of the tuners who are not experienced change some values in few maps. They wouldn't even know what would be the effect. This is the reason for flat spots, excessive black smoke etc post remap.

My advice to those who wish to remap :

1. Make sure if tuner has remapped the car before, if not don't keep high expectations.

2. Check the background of tuner. Ask people around. People don't like to reveal about problems. Simple way to check is to see if a remapped car was sold soon.

3. Don't go by power gain numbers quoted by tuners. Only a proper dyno run will give actual numbers.

4. Always keep in mind that remap is a calculated risk which you are going to take. Suppose engine life in stock map would be 2 lakh KM, with a remap it would reduce by 10 percent. I don't mind taking that risk and enjoy the drive for 90 percent of engine life.

Many argue that remap is better than tuning box. I wish to be more specific here. A bad remap would be more harmful to the engine than tuning box. It's very important that tuner should know what he is doing. Most of the guys use trail and error methods to remap. There are so many maps in ECU. Suppose you change values in one map, there would be another map which would limit it. So it's very important to make sure that the maps are tweaked accordingly and made to work in harmony with each other. I can name few maps : Driver's wish map, smoke map, torque limiter map, boost map, Injector maps like opening duration and start of injection, fuel pressure map, EGR map etc.

I think I have had experience with almost all the known tuners now.

Petes and Wolf remap for SX4

Code 6 & TOT remap for Grand I10

RD single channel box for Grand I10

I really love TOT map in Grand i10 and Wolf map in SX4

Special thanks to Kryptonite for helping out in 0-100 runs. It was nice meeting you.

TOT is indeed the best tuner in our Country. We remapped my friends Polo TDI there during the Bangalore floods. Vivek, like a boss, completed the remap in less than an hour. We did some extensive testing and the speeds we reached on the way to Chennai was mind blowing. 0 to 100 comes in a little less than 9 seconds. Thank you Vivek and TOT. Dr Naren hope you have fun with your Grand i10. Keep this thread updated !

I agree buddy. I am really very impressed with their working method. Vivek has all tools with him. Remember this is their first grand i10. I don't think anybody got grand i10 remapped in India before. Vivek checked all the parts and sent pics to Sid. A tuner should know about the components too.

Polo is a very mod friendly car and TOT maps work really good on VAG cars. They even have stage 2 mods for VAG.

I am planning to do V Box run tomorrow with new map. I will update the FE figures after doing tankfull at Mangalore.

Cheers!!

Dr.Naren, Congrats on your remap & finally you are happy
I read in detail about your bad experience earlier. It was not just bad luck, I know it's frustrating too. My Rapid TDI remapped by TOT. I'm very happy. As you said, TOT will understand the parts/components & its limits before laying their hand on remap. My observation, just for money sake they don't remap. They will map according to the tolerances of engine/gearbox etc. Now I'm preparing for Stage-2 map with upgrading the Turbo etc for my Rapid.
Vivek/Sid, keep up your trustworthy work

Code 6 tuner was not able to do a proper remap and kept doing tweaks. We spent around 5-6 hours and still car did not make enough power. Later tuner criticised my driving style and the car. I hope nobody goes through this kind of experience with any tuner. Sid came up with a good map within 1 hour and power gain was very significant with no black smoke. I would suggest TOT anyday. It's better to spend some extra cash and get it remapped from TOT. Sid is a certified tuner too. Your polo should be a monster post stage 2 mods. TOT gets all OEM VW components for the upgrade.

I couldn't manage to do Vbox run in new map even today. I drove to Mysore from Bangalore. This was the first time, Grand I10 felt sporty to drive on this road. I really enjoyed the drive. I would be driving back to Mangalore soon. I am waiting to see the performance of car post remap on Ghats.

I had plugged in OBD reader. Rail pressure, coolant temperature etc is almost at same level like stock map.

EGR is not switched off in the map. Sid told he will update the tune if he could do something and soft delete EGR. Providing a perfect tune for a hardly remapped car like Grand I10 shows their expertise.

I did not check FE figures. Based on fuel gauge, I can say that FE is good enough even with short bursts of WOT.

Hi, Glad to know everything worked out for you. I have spoken to TOT while I was working with Autocar India. One of the most humble and honest guys I have spoken to. I had called him so many times while I was writing an article on remaps vs tuning boxes and all the time he was super honest about everything.

Lots of good experiences from people all over team-bhp by TOT. Kudos guys, keep it up.

Note from Support: Guys, please keep the posts relevant to the car & TOT.

Code 6 has been discussed enough on the previous thread.

Thank You

Congratulations on the map! Vivek is one of the nicest guys I have ever met. A simple remap from them completely changed the character of my Laura.

On a recent run, Within 10 seconds I am at 85 and back to 60 with ac on and super light throttle inputs. This is is exactly what I wanted and the team delivered a 100%. Unfortunately I am unable to upload the video.

Congrats again and drive safe!

Thanks buddy!!

Vivek will listen to all your requirements and discuss with Sid. They will tell honestly what could be done. Sid will tailor the map as per our requirements. I have noticed that throttle response was better in 2nd map. I was actually happy with map 1 and was about to drive back after lunch. I guess Sid found something in map and sent updated file . Before we parted, I asked Vivek if sid would send another map .

Also, it's good to see so many guys happy with TOT remap and overall experience.

The level of dedication should be mentioned. When I took my friends Polo there was a flood in B'lore and also it was on the day of the bundh. All shops were closed and Vivek guided us to his home and the remap was done. He even offered us a lot of other goodies to make us comfortable due to the lack of shops. It is this kind of attention to detail and dedication that sets TOT apart.

I know what you are saying buddy . Dedication is 100 percent. Vivek was in Delhi and then he was supposed to go to Chennai. Still he managed to remap my car in Bangalore.

How to do a good 0-100 timing for diesel cars?

Kryptonite manged to do 16.9 seconds along with me in car. I took 17 seconds, when driven alone .

Best time of 16.2 seconds in stock map was done by Kryptonite.

I wish kryptonite did 0-100 timing in present map too, which is why faster than previous map.

Hi Doc,

I have been reading your posts from the last couple of months and believe me it gives me immense joy that finally, you got the grandi10 remapped according to your choice. Wishing you an ever big grin on your face. Happy motoring !!!

On a side note, do the TOT guys operate in Delhi too ? I was not able to find any local contact information on their website. I would like to get my Ford Ecosport remapped, however, it seems we don't have a legit tunner in Delhi NCR.

[Durango Dude]

You have the power now; does your car's stopping power need a revamp too or is it performing adequately?

Vivek would be travelling to Delhi to remap cars. Vivek was busy remapping cars in Delhi before he came to Bangalore to remap my car . I suggest you to get in touch with him. Ecosport would be a bench flash.

Grand i10 has very aggressive brakes. Intial pedal bite is too much. There was not much power and good brakes in stock form. TOT map made it a complete car. I think tyre upgrade is necessary.
