4. Why Choose CNG Kit Installation in Tata Tigor?
The Tata Tigor is a fantastic city sedan with a spacious boot, but its 1.2L 3-cylinder engine can return modest fuel efficiency when driven in stop-and-go traffic. For a Tigor owner commuting 1,200 km a month, petrol costs can easily exceed ₹8,500–₹9,000.
After CNG kit installation in Tata Tigor, the same distance costs around ₹3,000–₹3,500, delivering monthly savings of ₹5,000+. The payback period for a quality sequential kit is typically 7–9 months, after which every kilometre driven is pure savings. For ride-hailing drivers (common in Guwahati, Silchar, and Delhi NCR), our service can double their take-home income.
Beyond economics, CNG burns cleaner than petrol. Your engine oil stays cleaner for longer, reducing wear on internal components—provided the CNG kit installation in Tata Tigor is correctly tuned by professionals.
5. Engine & CNG Compatibility
Your Tata Tigor is powered by the 1.2L Revotron 3-cylinder naturally aspirated (NA) petrol engine. Because this is a port-injected engine, it is highly compatible with standard sequential CNG kits.
Unlike turbocharged engines which require complex high-flow reducers, the Tigor simply needs a high-quality sequential MPI kit. This makes the CNG kit installation in Tata Tigor process highly cost-effective, straightforward, and reliable.
| Specification | Tata Tigor Details |
|---|---|
| Engine | 1.2L Revotron 3-Cylinder Petrol (1199 cc) |
| Power / Torque | 86 PS / 113 Nm |
| Transmission | 5-Speed Manual (MT) / 5-Speed AMT |
| CNG Suitability | ★★★★☆ (4.5 / 5) — Excellent |
| Recommended Kit | Sequential MPI (Lovato, BRC, Tomasetto) |
6. The AMT Factor: Tuning for Smooth Shifts
If you own a Tata Tigor AMT, our CNG kit installation in Tata Tigor service requires extra care. The AMT (Automated Manual Transmission) relies on the engine's torque curve to decide when to shift gears. If the CNG kit is poorly calibrated, the reduced power output can cause the AMT to hesitate or shift too early, resulting in a jerky drive.
Our technicians specifically calibrate the CNG ECU to ensure the AMT's Transmission Control Unit (TCU) receives a smooth, linear power signal. We test the car in both city traffic (frequent 1st-2nd-3rd shifts) and on open roads to ensure the gearbox behaves exactly as it does on petrol.
7. Performance & Real-World Mileage
- CNG Mileage: 22–24 km/kg (City), 28–30 km/kg (Highway), 24–26 km/kg (Mixed).
- Range: Approximately 280–410 km on a full 60L (12 kg) cylinder.
- Power Delivery: A slight reduction in peak power is normal for any CNG conversion. However, the Tigor's longer wheelbase and torquey NA engine handle the extra cylinder weight well. With proper ECU tuning during CNG kit installation in Tata Tigor, the car handles steep inclines and overtaking with confidence.
8. Boot Space & Cylinder Options
The Tigor's standard boot space is a massive 419 litres. This is where cylinder choice becomes critical for your CNG kit installation in Tata Tigor.
60L Single Cylinder
Reduces boot space to ~200–210L. Thanks to the sedan's flat floor, the cylinder sits neatly, leaving a usable flat space for luggage.
55L Single Cylinder
Reduces boot space to ~220–230L. A great compromise for families, saving a few inches of depth.
Twin-Cylinder Setup
Two smaller tanks under the floor. Preserves ~80% of boot space. Replicates Tata's factory iCNG layout.
Pros of Tigor CNG
- Sedan boot shape gives a usable flat floor even with a cylinder
- Longer wheelbase = stable highway behaviour
- Lower conversion cost compared to SUVs
- Great value for families needing luggage space
Cons of Tigor CNG
- Boot still halved with a 60L cylinder
- AMT variants need extra care during tuning
- 3-cylinder engine note on CNG is noticeable

12. RTO Endorsement & Legal Requirements
Driving a Tata Tigor after CNG kit installation in Tata Tigor without an updated Registration Certificate is illegal under the Motor Vehicles Act. The RTO must endorse the fuel type change on your RC. Without this endorsement, you face fines, vehicle impoundment, and legal rejection of insurance claims.
We handle the entire RTO process for you. You will need to provide: Original RC, Valid Insurance (with CNG kit declared), Valid PUC, AIS-024 type-approval certificate (provided by us), Installation certificate (provided by us), and PESO hydro-test certificate (provided by us). Endorsement typically takes 7–30 working days.
13. ECU Tuning & Calibration
A "plug-and-play" CNG kit without laptop tuning will cause lean running (overheating, burnt valves) or rich running (poor mileage, carbon buildup). Our technicians connect a laptop to the CNG ECU and the Tigor's OBD-II port. We monitor short-term and long-term fuel trims, O2 sensor voltages, and MAP sensor data. The CNG injection map is adjusted so fuel trims stay within ±5–10% of the petrol baseline—ensuring smooth power delivery and maximum fuel efficiency.
14. Maintenance & AMC After Installation
- Every 5,000 km: Visual inspection of high-pressure lines, leak test, ECU diagnostics.
- Every 20,000 km: Replace low-pressure gas filter (near reducer).
- Every 3 years: Cylinder hydro-test (mandatory by PESO).
- Spark plugs: Inspect every 15,000 km; CNG burns hotter.
Our Annual Maintenance Contracts (AMC) cover all scheduled filter changes, leak tests, and ECU health checks after CNG kit installation in Tata Tigor. Highly recommended for commercial fleets and high-mileage owners.
15. Warranty & Insurance Impact
Warranty: Aftermarket CNG kit installation in Tata Tigor typically voids the engine and powertrain warranty. The rest of the vehicle's warranty (suspension, electricals, body) remains intact. If your Tigor is still under standard warranty, consider waiting until it expires.
Insurance: You must inform your insurer immediately after CNG kit installation in Tata Tigor. The policy needs to be endorsed to include the CNG kit. The premium increase is usually ₹1,500–₹3,500. If you do not declare the kit and suffer a gas-related incident, the insurer can legally deny the claim.
16. CNG vs Petrol Economics
| Cost Factor (Monthly, 1,200 km) | Petrol (Tata Tigor) | CNG (Tata Tigor) |
|---|---|---|
| Fuel Cost per km | ~₹7.50 | ~₹3.00 |
| Monthly Fuel Bill | ~₹9,000 | ~₹3,600 |
| Monthly Savings | — | ~₹5,400 |
| Kit Payback Period (₹45k kit) | — | 8–9 months |
17. Installation Process Step-by-Step
Step 1: Health Check (1 hour)
Scan OBD-II for existing faults; check engine compression and spark plugs to ensure your Tigor is ready for gas.
Step 2: Mechanical Fitment (3–4 hours)
Mount cylinder brackets securely to the chassis; route the high-pressure line; install the filling valve.
Step 3: Plumbing & Wiring (1–2 hours)
Install the reducer, connect coolant lines, and wire the CNG ECU and injectors with waterproof harnesses.
Step 4: Leak Test (30 mins)
Pressurize the entire system and apply a soap solution to every joint to check for micro-leaks.
Step 5: ECU Tuning & Road Test (1.5 hours)
Calibrate fuel trims on a laptop; test drive on petrol and CNG (especially critical for AMT models) to ensure smooth shifting.
Step 6: Documentation Handover
Provide installation certificate, PESO certificate, and guide you on RTO submission for RC endorsement.
