Vgate iCar Pro 2S Review: My Favourite Budget ELM327 Adapter
Published: October 14, 2024 · Last updated: June 4, 2026
The Vgate iCar Pro 2S is one of the cheapest ELM327 adapters you can buy, but it runs the newer ELM 2.3 chip and works on iOS, Android and Windows. I tested it on a Fiat Punto, a Toyota Corolla and other used-car checks. For an entry-level adapter it gave surprisingly good speed and dead-easy connection, it’s my favourite budget ELM327. It’s engine-only and not a scanner, so know what you’re buying. Read on for what it does well and where its limits are.

What it’s actually good at
It’s cheap, reliable and just connects, the whole point of a good ELM adapter. No pairing headaches, works across iOS, Android and Windows, and pairs with any ELM327 app (my pick is Car Scanner Pro). The newer ELM 2.3 chip helps stability and speed: around 21ms response in my test. That’s not as quick as a vLinker MS or OBDLink MX+, but for normal diagnostics and logging the difference is small, and the price is a fraction of theirs.
Despite being a basic adapter, it caught a real fault cleanly, and that’s the proof it’s fast enough. On a rough-running engine the live data showed short-term fuel trim around 70%, which instantly pointed to a vacuum leak: the ECU was nearly doubling the fuel, and the oxygen sensor had stopped reporting values. The adapter updated fast enough to see all of that happening live. For diagnosing common engine issues like vacuum leaks, fuel trims or O2 behaviour, it does the job.
Through the app you also get the usual extras: smoke-check readiness monitors, fault reading and clearing (it found pending O2 codes and a confirmed P0500), graphing multiple PIDs at once, CSV logging, fuel tracking and a phone HUD. Everything displayed correctly.
Where it falls short
It’s engine-only, full stop. No full-system access, no live data beyond the engine, no bidirectional, no coding. It reads and clears engine codes and shows engine live data, and that’s the ceiling. It’s an ELM adapter, not a scanner, so don’t expect ABS, airbag or module work.
Build and speed are still below premium adapters. It’s good for the money, but quality sits under something like an OBDLink MX+, and if you want to push into ECU coding or serious performance logging, you’d want a faster adapter like the vLinker MS. The more PIDs you graph at once, the more it slows down too.
Who should buy this
Yes, buy it if:
- You want the cheapest reliable ELM327 for reading engine codes and live data on your phone
- You value easy connection across iOS, Android and Windows with any ELM app
- You’re doing basic engine diagnostics, fuel trims, O2 data, smoke-check, not module work
No, look elsewhere if:
- You want full-system access or bidirectional, the Mucar BT200 Max or Konwei KDiag do that for similar money
- You’re heading into ECU coding or heavy logging, a faster adapter like the vLinker MS suits better
- You want premium build and the fastest response times

Still deciding rather than chasing an iCar Pro 2S deal? I line up the budget ELM and Bluetooth adapters I’ve tested in my [best ELM327 OBD2 scanners] roundup. The short version: the iCar Pro 2S is the budget ELM I’d pick, but the roundup shows where a faster adapter or a full-system tool fits you better.
Final word
The Vgate iCar Pro 2S is my favourite budget ELM327 adapter: cheap, reliable, easy to connect across any platform, and running the newest ELM version. It’s fast enough for real diagnostics, it caught a vacuum leak cleanly through fuel-trim data on a rough engine, which is all most people need from an ELM. It’s engine-only with no advanced functions, so if you need more, look at a full-system adapter. But as a cheap, dependable entry to app-based diagnostics, it’s the one I recommend.
