LPG is a bit of a devils advocate D it's great when it works but frustrating when its not.It's taken me alot of ups and downs to get my car to where it is now and ive got to admit ive thought about putting it back on fuel many times. But now I think ive got the LPG part mostly sorted and the car runs well its just a big learning curve. Like Mik said if your not prepared to put in the devolopent time I would stay clear of LPG even with injection. No one I know of makes a kit that can be run with a stand alone ecu? and not piggyback of the factory one and if there is let me know
