When you should buy this software

We don’t want your precious money for nothing, so this is a quick guide of wether you need the software or not.

Misfiring diagnosis

If your vehicle is misfiring and hiccing up during acceleration or just idling, you should be 100% sure that the problem persists ONLY when the LPG/CNG installation is switched ON. If you are having problems on petrol as well, please look up into it first. Common problems for this can be Spark plugs, Ignition coil(s)/leads or faulty wiring and not the LPG installation itself. Often those problems can be detected with a OBD Scanner and basic symptoms are FLASHING CHECK ENGINE LIGHT.

Check Engine Light / MIL (Malfunction Illimination Lamp)

If the check engine light (MIL) is illuminated/ON, you should probably consider looking up into it and understanding what the code is. Possible codes that can be caused by a wrong tuning of the LPG systems are: Mixture too Lean or too Rich, Lambda probe voltage issues, Lambda probe no activity, Misfire on Random or Detected cylinders (characterized), Fuel Pressure issues and some more depending on the vehicle model.

Real customers talk

Some real testimonials of people who have bought the software. If you want yours here, wether is good or bad – we will publish it!

I can’t thank you enough. I spent over 2 months going from shop to shop, some didn’t have the program, some had it but couldn’t fix it. It turned out to be a really sketchy error – the water temperature sensor. But it was only going bad when the car is fully cooled down (below 20c). I have changed it and my LPG system switches like it was before, not after 20km driving!
