Hello,

ECU is in layman language is brain of car engine - which controls engine performance
What it effectively does is that it collect information from various sensors (coolant, air flow, idling, throttle, oxygen, temperature and other sensors ) as installed in car and controls in several engine actuator like pulley, crankshaft movements and other engine parts

ECU Tuning can help in
> Air / Fuel Mixture
> Idling Speed including Idle Engine RPM
> Valve control and timing

In terms of ECU Updates - its performed in all modern cars.
Been if vibration is on a higher side - the ECU Update can increase in idle rpm to prevent vibrations. If a Manufacturer launches a ECU Update Software - then it advisable to get the same updated as it can yes possibly control in the vibration and engine performance optimally

However - just to be noted that as you planning to buy a new car, ECU would have already been updated. Generally 1 or maximum 2 ECU Updates are released in a calendar year by the Manufacturer. So - at a later state - if any such update is there, you can perform this at Tata Workshop

Hope should help !!

I took the test drive of Petrol Tiago today, the moment i started the car and watched in idle mode, i felt vibration at gear box, clutch panels, even at front end desk of stearing. Although when i drove the car i dint feel any vibration. I am confused will it be impact-full in terms of performance in future.

TATA guy who visited with car mentioned about this update that the vibration goes after the same, but his car itself was driven over 4000 Kms, so when i asked why dint you get the update done in this, dint get the satisfactory answer also, he recommended for new car aswell to go to get the update done, onto which i think the new models are also not being updated with the latest update and will have to visit the service center to get it done.

2ndly i observed that ARAI claimed miealge is 23 in petrol variant but when i checked his test drive car meter i found only 9.6 KM as average, which concerns me, cause my 10 year old wagon r is giving me the same, so i dont see much difference driving this or my wagon r considering fuel efficiency.

Any thoughts ?

thanks

Hello,

1. ECU Update is more like a Software Update and is released often time to time
Its true that Engine Vibrations are there and observant on Idling or on high speed in Tata Tiago
Also -- the new batch of cars produced likely to have updated ECU and a requirement of ECU update may not be there.

2. Mileage as claimed of 22 to 23 Kmpl looks good on papers, but in more than 98% of the cases is never achieved in real life
Been - the claimed mileage is based on test simulation conditions. Adding to it - would also comment that 9.6 Kmpl mileage is too low and is also generally not possible in real life conditions

Been its a vehicle used for dealer test drive, where test drives are limited for short distance - low speed, often on low gear - the mileage is always lower on test drive cars. It would be safe to get in 14+ mileage in real life city driven conditions

You can ask dealer for long test drive of 25 to 30 Km and reset the meter - before going in for mileage calculation

Hi,

I think Tata Tiago is sold for more than 20000 Nos, by now as per Auto Portal.
Can Actual buyers update on following 2 parameters.
1. Vibration in City traffic
2. Mileage in City traffic/conditions

Looking forward for your inputs to benefit others as well

I own a TATA TIAGO PETROL from the past 3 odd months and i have just got it serviced from the service center.(2nd free service).
Its pretty disappointing that the technicians are unable to resolve to vibration problem that the car faces during idle.(Neutral with no input on the accelerator).
The vibrations fill up the cabin and the buzz can be felt through the clutch, gear lever and the steering wheel.
Given the three cylinder architecture of the engine without a balancer shaft, vibrations creep into the cabin.
Still, increasing the idling speed of the engine by 500-700 rpm from the regular idling rpm dampens the vibrations to a much tolerable level. On the flip side, the fuel economy is bound to take a hit.
Really disappointed!
Hope TATA finds a measure to rectify this issue ASAP!:(

after 1.5 months, after first service, the gear vibration increases and i think the speed sensor locked automatically. gear not engaging to the engine after few throttle.
example : goes in 1 st gear upto 10 kmph, after that acceleration over gear engagement suspend.
2nd gear 20 kmph , 3rd gear 40kmph, and 4 gear 60 kmph, and its final you cannot increase speed further in highway. when you push the accelerator the engine engagement to the gear suspend. vehicle comes to idle. check engine symbol glows.
what i have to do help me.

Hi Dharmen, I am riding a Tata Tiago Petrol from the past 2 months. Here are my observations.
Pros:
--> Getting 20.7 kmpl in Highway ride. City its 18 to 19.5 kmpl.
--> Ride quality is good. Suspensions are too good in bad roads.
--> Lots of features for that price tag.
Cons:
--> Initial moving (1, 2 and Reverse gears) vibration is too high. Its very hard to drive in a city traffic due to vibration. Its irritating us. Always riding in high accelerator in city traffic.
--> Idle vibration is also there but compared to Initial moving vibration its ignorable.

Is any one getting the same issue. please update.

Hi Dharmen,

I have been driving my Tiago-XZ petrol variant since 5 month over 4300 happy kms. I am pretty impressed with the fuel economy.

Most of the distance are covered in Busy Bangalore traffic(many time I got bumper-to-bumper traffic) @ 15 -16 kmpl (AC on) and I had been to outstation and covered almost 900 km @ 23 kmpl (AC and ECO mode on).
However, on urgent move driving at high speed (avg @ 120 - 140 kmph), I got 18.5-19 kmpl on highway. (of course I had to turn off ECO mode)

In lower gears and uphill situations I do get vibration and noise from the dashboard and gear box. Even after 1st servicing the noise do exist.
My car had a bad fitting in the driver-front side panel(where you can find a parking ticket holder). I got the clip replaced and the noise is much reduced.

Moreover, 4 people on board, in lower gears (say 2nd gear at speed breakers) lack of power will tend you to shift to first gear. Ideally other 1.2ltr engines will drive you through quite smoothly. Initially that was quite annoying for me, but owing a 3 cylinder engine, I got used to it.

Considering the price offered with loads of features compared to the competitors, it definitely a Fantastico car...!!!

Hi

I have been using Tata Tiago XZ(Diesel) for the past 2 months. Initially I was very happy with the performance and mileage of the car but now I feel there is vibration in the engine. I have been to showroom more than twice regarding the vibration issue. The service center has changed the A Mount in the engine but the issue seems to still exist. There is vibrations when the car is on 2nd and 3rd gears which makes it more irritating to drive in city traffic.

Tata RND team is not doing anything of vibration so for. They are just concentrating on selling the cars.There are many car manufacturer in market doing good RND and resolving the any issue reported by their customers. but ,TATA RND team not doing anything for engine and gear vibration even after a long. it shows the insufficiency they should learn from others in market.. pay 6 lakhs and asking customer to accept vibration

I dont think the vibrations would go as its been a year since i test drove tiago and i too felt the vibration on the clutch pedal, gear, dashboard and steering. The sales guy tried to convince me saying that its a test drive vehicle etc etc but i wasnt convinced, I increase my budget and bought elite i20. Tiago is a great product, the build quality, music system, ride quality everything is great, if there hadnt been the vibration issue it would have been maruti killer in its segment.

Hi Everyone,
I Own a TATA TIAGO XZ REVOTRON, XZ Variant since August 2016 (19Months) with ODOMETER Reading at 27,700Kms. Let me share my ownership experience with you All.

1)APPEARANCE: A Good Looking Hatch, A head turner, Front looks like JAGUAR( btw it was designed by Jaguar designers).

2)ENGINE: 1.2L , 3 Cylinder Mill, 84BHP sufficient power for Sedate driven , Overtakes need some planning. Best Driven Between 80kmph to 100kmph , Vibrations are felt though but Bareable.

3)FUEL ECONOMY: I live in a Tier 1 City (CHENNAI), CITY (with AC) is 12-13.5Kmpl Average and HIGHWAY (with AC) is 18- 19kmpl if driven in 100 to 110kmph , 19-21kmpl if driven in 80kmph.

4)SPACE MANAGEMENT: This Car best suited for 2+2 for a comfortable ride. Sufficient Headroom and Legroom for Adults. Lots of storage space.

5)BUILT QUALITY: Well Built and feels solid enough ( way better than Maruti’s).

6)SAFETY FEATURES: ABS and EBD a lot helpful for our Indian road conditions.

7)RIDE QUALITY: Awesome Suspension for our Uneven Indian Roads and Craters. Less Body Roll, and absorbs most of the bumps well. Steering feel is good Enough.

8)ENTERTAINMENT: Best in Class Music system by HARMAN, with Bluetooth connectivity for Music and Calls.

9)SPARES AND SERVICE COST: Spares arent much Expensive , and Each service should cost you not more than 3000 INR.

10)SHOULD YOU BUY ONE: Best Value for money Car in this Price Range with respective to Built quality, features, space Etc.

ALTERNATE OPTION: if you could stretch a little more get the HYUNDAI GRAND i10 , what you get is a refined motor with goodies.
ALWAYS BUY THE TOPEND VERSION OF THE CAR MODEL YOU BUY ,THAT IS FULL LOADED WITH SAFETY AND FEATURES.
THANK YOU

I brought Tata tiago in 22nd April 2018 almost a week. I completely disappoint due to the performance of the car. Too much vibration in hidile mode and engine is produced too much noise. I have poined the issue in salesperson they said test drive is used roughly its not same in normal one. Now I completely felt my decision is wrong. guys pls thing before buy tata car. They improved other futures but fail the importance one(engine noise) spending 6.3 lakhs u can buy other brands.

Thanks

Hi am driving tiago XZA from october 2018. im very much satisfied with the over all performance like safety mileage and so far,
but my only concern is that when ever i stuck in traffic vehicle doesnt move on initial accileration . it will will take 3-5 seconds for the vehicle to move. which is quite annoying as i can hear continuous honking from back side drivers. tata is not pretty sure about the problem. but this happens only with AC on. other wise its good.
