LPG is a less dense fuel. SO you use more of it (yes, you can get way more power as the octane rating is very high if you build the motor to run dedicated LPG... But it'll still use more). Fuel economy is probably 20% worse.Quote:

Hi Blokes,
I thought I might add something here to the fuel economy issue and I'm probably preaching to the already converted here,[bigwhistle] but a year or so back I fitted 245 70R16 tyres to "VILET" (1986 RRC) but found that the fuel consumption went up dramatically.
The reason for this was that the tyres were 730mm in diameter and the standard recommended tyres were 700mm, which then makes the odometer reading wrong.
I then compared the odometer reading with the Kilometers actually travelled and found that in my case the odometer was reading 12% less than what had actually been travelled, so this had to be calculated into the economy figures when working off the odometer reading thus making a big but positive difference to the economy figures.
:soapbox:Ok I'll get off now.

They are a speed sensor correction device.
v4 is for hall sensors. They also do a 2-wire VR sensor version.
I have it in my 300 coupe and the RRC. Best bit is the speedo is absolutely dead accurate because you callibrate it with high-speed gps. Or you can deliberately program a "safety margin" in once you have worked out the correction factor, so that your 105 is actually 100 - just in case your speedo has been so far out of whack for years you cannot get used to an accurate one.
That is interesting. I tend to just check the speedo with my phone (gps). Most of them are quite close. The modern ****boxes are often understated by upto 5km/h at 60km/h. I have the most issues with my old cars wth mph speedo. Do you think I can remember what odd speeds like 40km/h, 50km/h and 80km/h are in mph....Quote:

Just keep in mind it's illegal for the speedo to read less than the actual speed and it makes your vehicle technically unroadworthy, which could affect your insurance if you crash and assessor uses it as an excuse to reject your claim.
On fuel economy, the figures mentioned scare me, as my Puma Defender only uses 11 l/100 kms when towing our camper.
the ****box here uses easily 35L/100kms towing the block of flats. Most petrol 4wds made in the last 50years will return similar economy sadly (they just don't tend to talk about it like land rover owners do).Quote:

Yeah isn't that something.Quote:

By the way the Toyota was a non turbo diesel.
My mate was a bit disgusted at the ease at which I climbed over the ridges and then pulled him over so when he got back to home me went straight out and bought a Detroit locker for the Tojo, to which I thought at the time might make a bit of a difference but not solve the problem totally.
