.. for popping over tonight and providing advice and moral support while I drilled tank mounting holes in my MV6.

 

Should be plain sailing from here when the rest of the LPG bits arrive.

How was the LPG on the way back?

Damn nice chap that Jason

Did you have a play with his LPG system then Kevin??

Upped the pressure a little as it was struggling when flat out.

Jeremy was saying that he sets a 5000rpm limit on LPG then it switches over to petrol :-/

The standard preset in the software I believe is 6000 /6500 rpm.

If the LPG is set up right, there's no reason you can't redline it on gas.

I used to give my 2.5 facelift a real spanking all the time on LPG, and I never noticed a drop in performance

It was a pleasure Kevin


It felt a lot more lively on the way home, don't know if that was a placebo effect but the one time i really did rag it the car still jolted but nowhere near as violently as it did when we were testing.
It was the midrange where it seemed to improve a hell of a lot

I'm going to get it on the laptop tonight and see if it does need recalibrating, and i might have a go at tweaking the gas pressure a bit more to see if that will iron out that jolt

It would be good to get a definitive answer as to what pressure range that system can cope with. I found some specs on the injectors and they are rated at 450kPa - which is 4.5 BAR Not sure if that's operating or not though. :-/

Gas pressure does seem to drop a little with engine load, and there's a big  spike in the petrol injector duration when it upshifts from the redline which I suspect the LPG system can't respond to, hence the jolt.

It will be interesting to see how it copes with my 3.2. I note Jeremy's ad states that the Vapouriser is rated at 320 Hp. Didn't ought to be phased by a V6 Omega.

Can you remember what gas pressure your 2.5 was running, James? That had 2.5 mm nozzles, IIRC?
