The worse I've ever managed over a tank is 16mpg, and that was trying Shocked

I think mine is uber poorly Sad

I've checked for leaks and tightened up all connections and I can't find any problems. I do think it is a fueling/mapping problem as the power & torque are much reduced when running on gas and the idle is quite lumpy especially when the engine's colder.

Should the stag ecu tap into my lambda probes? Or is that controlled by the injection pulses that are sent out by the engine ecu? As the wires for the lambda probes on the stag ecu are not connected... I may have just answered my own question again Cheesy

Lamda connections only required to help the calibrator calibrate on that one...

Yep

The Stag software (in theory) doesn't need lambda inputs but you're asking for a whole world of trouble if they aren't Wink

Get them connected up ASAP and if the performance is that badly affected I'd advise you not to use LPG until you've looked at it properly Wink

Fair comment Embarrassed

Through the supplier we use (think they're about £20+VAT) from him but don't quote me on that Roll Eyes

Would you like me to try and add one onto my order if it wasn't shipped today? (as that will save you the postage cost Wink

)

Thanks buddy i'll give them a buzz today Thumbs Up!

Driving into work this morning on petrol made me realise just how badly the lpg system is performing! On petrol it's so much smoother and more powerful, it feels like effortless power whereas on the lpg it feels like a real effort. The MPG figures on my MID are also much improved, cruising up the M5 today was giving me an instant consumption of between 35 and 45 mpg

In conclusion, I desperately need a Stag lead so that I can plug into the ecu and see what the hell's going on!!

What's the condition of the plugs, dispack and leads? LPG is more demanding on the HT system and it must be in top condition I actually think the problem is mixture related from your description but these things need to be checked properly
