[quote="57jam89]So if I do decide to lpg it I will need new reducer, ecu and injectors. Also don't think the tank will fit.[/quote] Relevant tech knowledge and experience, which might lead to components being swapped during the install etc also come into their own, particularly on an install that is anything other than straightforward.
Points I raised wouldn't put me off converting the Mito. Plenty will have been converted including some by DIYers. No doubt most suppliers would be more than happy to sell a DIY kit which is claimed to give excellent results on the Mito and it is likely suppliers believe such claims. There is a chance such claims are true but where true it is more likely due to luck than judgement.. Suppliers may not have personally converted a Mito, may take manufacturer's hyped claims as true without question, may assume there is no problem regards suitability of parts if end users (including pros and DIYers, whom may have varied expectations in both cases) achieve half decent running on LPG. Suppliers may consider results successful when they stop receiving tech support calls after giving a bit of advice but that doesn't necessarily mean the vehicle drives as well as it should/could on LPG.. Suppliers seldom see the results first hand.
Common scenario - At some future point the car is sold and the new owner isn't as willing to put up with the slight niggles running on LPG so brings the vehicle to me for fettling, where I find the components fitted and/or the setup/calibration would never be able to provide good results. If I had converted it I may have swapped component X during the install and calibrated in a different way.
It may be the case that the technical points on threads I linked to don't have much bearing regards Multi-air, in which case parts selection and setting up could be straightforward at least to obtain what many would consider acceptable results... I might have improved on the results but the results seem OK so not a problem. But I would expect some of the points in threads I linked to to be relevant and therefore to expect some swapping of components etc during the install, implying a DIY install might not be the best option. I would know better than to think all was well just because tech support calls stopped coming in.
Say you fitted a DIY kit from a supplier and achieved acceptable results most of the time, just a few niggles. Then you come to me and I say 'Ahh, my interpretation of all these numbers on screen, fuel trim info and that slight bit of hesitation, is that to improve the situation you should really have fitted different injectors'.. I'd be charging you for my time, the supplier might say 'We have supplied the same components for many Mitos and insist they give good results, it is too late for you to change them anyway now they're used'. You might decide to change to the parts I advised but buying them would offset the money you'd saved by fitting the system yourself, so maybe you might as well have had me fit the system in first place. If I had supplied the DIY kit I would change the bits but that would mean I had made a loss from supplying the DIY kit not to mention the time I'd spent giving tech support, so I won't supply a DIY kit for this model until I've converted one myself.
Thanks again for your advice.
What I'm (well the wife) going to do is run it for a 4/5 weeks before going down the lpg route. And if/then we do I was thinking of you supplying the ecu and reducer (if the magic jet one will not suit) and then myself fitting the tank, reducer, nozzles into inlet manifold, ecu and some of the wiring and then coming to you for a day so you can fit/play around with injectors and set it up.
The main reason for this idea is because of the distance between us and the car is needed every weekday. What you think?
