I have a non turbo 1996 skyline which has just beeen converted to LPG.

The Dyno was broken and couldnt be used so the car was tuned in the garage.

Will there be any or much difference if I go back and ask for a dyno tune when the dynometer is fixed up?

If it was a turbo would your response be any different?

I suspect the fuel econmy could be better but I am still getting used to the conversion.

The system is SVI (sequential vapour injection) and I am assuming an extra 20% fuel consumption compared to petrol.

What do you mean by it was tuned in the garage :banana:

To the OP you definetly have to get it dyno tuned under load otherwise its all just guess work by the tuner and a close enough approach that is most likely going to run rich eating fuel like crazy. Using guess work you gotta be on the safe side so they definetly cant have you coming back with your engine blown to pieces because they cbf fixing their dyno.

There would most likely be a world of difference in terms of both response and economy if it is taken back and tuned properly.

Out of curiousity what ECU are you using for the conversion?

The conversion was an EMER system supplied by Aust warehouse LPG. Does thta help with the ECU type?Where would I look?

      Mistakes were made, my R34 Story

      Ah yes, but the part in my hand was actually painted and fitted by me! I knew any front lip was likely to be sacrificial but I've had to fix it twice already... by the time I buy a fibreglass fixing kit, sort out sandpaper blocks, buy some fibreglass filler, body bog, spend the time and effort for a 'Greg' result... a new one being $290 seems like it's the better way to go and spray that with bedliner/raptor coat and we're all pretty again.. Would have preferred it last more than a month though. Them's the breaks I suppose.

      I find it funny that the USA is finding out all this really really weird stuff, and people from the USA are coming here treating it like gospel, yet, all the info on solving those issues is here on these forums for the last 15 odd years... Also, I know how much heat it takes to ignite the hood lining of an R33 skyline. I worked it out myself... It also took a LOT of time, and heat for it to do it... Big single, and I needed to drive the car, so retarded the timing off to "protect it". Yeah, that was a bad move for cruising on a freeway with only 15 degrees of timing on it. That was a lesson I learned around 2009. So that's over 15 odd years ago. Aligning water and oil, that's identical for any turbo engine, it's not Japanese specific. If a shop doesn't know how to make sure the core is rotated the right way, then they shouldn't be touching any turbo engine. That's not a matter of "We haven't had Skylines for that long here"...

      Sounds like it is rotational in the driveline. CV? Tailshaft CB? Also.....didn't you just pay to have that bit painted and put on the car?

      R34 GTT idle problem

      By GTSBoy · Posted

      Yeah, when I dialled my idle down, given how much time I spent idling at the lights in traffic on my daily commute, the effect on overall fuel consumption was absolutely noticeable.

      Emissions, fuel consumption, heat, noise, etc. most likely.
