Thanks for your note. I am yet to do the TD. I will take this point in account when I try. In general, I have tried driving multiple cars (from my friends) and for me turbo lag wasn't an issue most of the times.

The intend of the torque boost is not to increase the torque. What it does is to help take some load of the diesel engine so that the efficiency is increased. And even for this to happen, several criteria needs to be met like

• The battery terminal voltage should be above a certain threshold
• The battery charge should be above a certain threshold
• The engine should have already reached the normal operating temperature
• Throttle position between lower and upper threshold

Turbo lag becomes an issue when you drive in a city and when you want to zip through the traffic. I recently drove a 1.5L VW Diesel Polo and was waiting for ever for the turbo to spool up. Same is the case with any vehicle with a big turbo charger ( compared to the engine size ).

You get to appreciate the goodness of lack of turbo lag when you start driving the lagless engine through the city traffic. Prime examples being the Honda i-Dtec, Renault Diesels ( the smaller PS ones ) and even the Etios D-4D. On the highway, what you need is not hard acceleration, but better dynamics, braking, tall gearing for effortless cruising, Give me any turbo charged Diesel car in India with more than 150 Nm of torque, and I can bet that I'll reach a 500 km destination in almost the same time. So, all of that additional PS doesn't matter much in real world driving even though it might matter in a drag racing. But, having a lagless engine reduces your driving stress multi fold in city traffic conditions which you will encounter a lot in India.

I consider the Honda Diesel engine as the best of both worlds. It has the power for fast highway drives, and it performs equally good on city traffic conditions.
Another one which performs flawlessly in both these conditions is the Ford Figo Aspire's new diesel - 215 Nm from 1750 rpms to 3000 rpms!
An engine, I'm eagerly waiting for is the Toyota 1.4 Euro 6 Diesel. It will give you 205 Nm of torque from as low an rpm as 1400 rpms all the way upto 2800 rpms! Hopefully, it might make its debut in an year or two on Vios & Corolla.

I happened to see "torque assist" as one of the technology available. I tried searching elsewhere but couldn't get the understanding. Apologies if this is already discussed in this thread. Can somebody enlighten me on this?
Also, I am based out of chennai. Could friends from chennai let me know what is the average fuel consumption that i can expect and which service center/dealer could be considered?

I own a Diesel SHVS VDI. I donot see any significant difference in Torque assist. SHVS kicks in when accelerating for a few a seconds and battery charges when I am not on the accelerator. Regarding FE I am still to do measure a full tank to tank. The instrument panel shows

I am from Bangalore so will not be able to recommend MSIL in Chennai.

12 - Bumper to Bumper traffic mostly 2-3 gears
14-16 Moderate traffic with 2-3-4 occasional 5
18-22+ Highway at 80-90 mostly 5

Surprised you said that on the Polo because I took an extensive test drive of the Vento (bigger car) with the 1.5 TDI and it was one of the most lag free engines I've driven. Of course, the brute force of the 1.6 was slightly missed but nowhere laggy. Acceleration was linear and tractable.

Actually, not quite and hard acceleration is very important in the highway and the engine's eagerness at those speeds matter. My family and my cousin's family had to attend a wedding in Madurai, a distance of 480 kms from Chennai. We started together, me in my Ertiga and they in their Fortuner and within seconds the Fortuner disappeared on the highway and as much as I tried, I couldn't even spot it until our next pit stop. And at every ~200 kms, they had to wait at least 20-30 minutes for me to catch up! In fact, at lunch time, they finished their lunch and were leaving while we entered!

The same stretch of (Salem-Ulundurpet) NH68 that I do on the Lodgy shaves off almost 40 minutes in comparison to the Ertiga.

Again, surprised. I've extensively driven my cousin's Mobilio in the city and the highway. While in the city it's lag free, the same cannot be said on the highway. Yes, it's par for the course but the i-DTEC is not eager to do 3 digit speeds on the highway and I always get the feeling that it'd rather do slower speeds better than high speed cruising.

Sorry to go off-topic, folks, back to Ertiga discussion now.

I'll list down all cases here.

For Engine Auto shutdown @ idle on Neutral

1. Driver side seatbelt should be fastened
2. Driver side door should be closed
3. Bonnet should be closed.
4. Vehicle speed should be less than 3 kmph
5. Engine rpm should be at idle speed
6. AC shouldn't be put into Auto Mode
7. Engine should have warmed up to operating temperature
8. Battery voltage and strength should be above a threshold.
9. Brake booster vacuum should be above a minimum threshold.
10. No trouble codes related to SHVS system
11. Vehicle shouldn't be on a slope

For engine automatic restart without clutch depress

1. If the vehicle starts to slide down a slope
2. If brake vacuum is below the minimum threshold
3. If AC need to turns ON to maintain the set temperature.
4. If Battery charge below threshold
5. If it's 3 minutes since auto stoppage

In addition to the above, there is a manual override button as well.

Torque boost works the following conditions.

1. There should be a throttle input in the range specified
2. Brakes shouldn't be depressed
3. Battery is fully charged
4. No headlights ON

Another interesting thing is that the vehicle restart when clutch is depressed is performed by the ISG ( Integrated Starter Generator ) and not the starter motor while the normal start is handled by the starter motor. Not sure about why it's done so though.

The first thing I did when I felt this was to check the comments on team-bhp. And I saw people said there is no lag. But, my friend - Ashok who was driving my Etios said that the Etios felt much quicker in the city. And it was infact the same feeling that I got. Only 2 reasons I could think of.

1. Turbo lag
2. The pollution cheat device of the VW at work.

It depends on the kind of gear shifts you do and the speed at which you plan to cruise at.
If your cruising speed is 140 kmph, these high value PS numbers doesn't matter. You can easily be on that speed all day on a lagless 68 PS engine. It's relative speed that saves you time, not acceleration. And any speed over 140 kmph, I don't consider it safe on Indian highways for consistent cruising. You can do short bursts though.

The fastest, I've done in the Kochi - Trivandrum highway is using a 1000 cc Maruti Suzuki Zen ( not mentioning the numbers here because I do not want to promote unhealthy competition ), not with the 90 PS Esteem or the 170 Nm torque Etios Diesel. So, it was just the driving skills and mood which limits me in getting good timings on Indian Highways, not the lack of PS numbers. Slot it in the right gears, reach a good cruising speed and you will clock good highway timings. PS doesn't matter at all. But, if you are doing a drag race, yes it matters.

I haven't tried the Mobilio, but I've tried both the Amaze and City ( using the same engine ). Both of them are gems for fast driving . Mobilio, I don't think is a worthy 7 seater anyway ( not because of the engine though ) because its 3rd row seating is downright pathetic compared to the Ertiga's

Why would you want to do such modes, especially since it's not a Maruti Genuine Accessory. A closed window even affects your safety in case of an unfortunate incidents like fire/accident. Don't take risk with these 3rd party products. You might end up in a really bad situation due to these non-MGA modifications.

Quite agree with amalji here. One of the primary reasons for not installing this up-module is the Safety itself. I would stay away from this unless genuinely necessary.

Installation is not at all cumbersome and there are a lot of friends who have done in their cars (Not an Ertiga though). However, I still remember a case with a Scorpio that started emanating burning smell while we were on a group drive and the culprit turned out to be this up-module that he had installed.

My take on this is - Really not worth an accessory that you want to install at all.

I cannot watch the video and i am not sure what do you mean by disconnects. From what i remember if you want the iCarplay working you need have your iPhone unlocked all the time . If the phone locks car play would disconnected , go to iPhone setting and set auto unlock to 'Never" and check if it works

Video is playable. If you cannot watch ,please click the link on top of the video to watch it on Youtube.Iphone is unlocked all times. Tested on my Ertiga as well as on a Ciaz. Same problem.

All settings as suggested are taken care. As you see in the video the phone is connected but after sometime or during a call as seen ,it disconnects. The problem has been referred to MASS,Maruti regional office. They have acknowledged the problem . Even the MASS Manager has spoken to the BOSCH helpline but no solution till date.

Friends, is there a way to upgrade the preloaded maps that come with ZXi+; apart from getting it done by the dealers? The one that I have isn't the latest and would like to upgrade it.
