I thought I would give a report on the engine watchdog and scanguage fitted to my vehicle, firstly vehicle details, 2003 Toyota Landcruiser 100 series V8 petrol, 285/75/16 BFG AT tyres, storage draws full with recovery gear etc I do not have a roof rack, when towing we have a 1997 Regent Legend poptop duel axle caravan, ATM1960Kg.
I fitted the engine watchdog first to the bolt on the thermostat housing, non towing temps are around the 60 to 65c, towing showed around 70 to 80c, I adjusted the scanguage 5% to compensate for the larger tyres and this corresponds exactly to the reading on the GPS, the guages showing on the scanguage are lhk (litres per hundred klm),
water temp, kph and volts, there are another 20 guages that can be shown.
Water temps for the scanguage show, non towing 90c, and towing not much more to around 95c
The interesting guage is the lhk, non towing yesterday going shopping in
Grafton NSW which is a round trip of 100ks showed 14.8lhk, not bad with the larger tyres and 2 weeks of shopping, that figure is about normal for non towing, when towing the best I have recorded is 19lhk and the worst 22.5lhk over 18.000 klm of towing and this has been backed up using the mileage and
fuel fill up independent of the scanguage to see how close the guage is, and its pretty close.
So the scanguage does work on my vehicle but I am not sure if it works in the diesel model, I am now looking and changing the watchdog from the thermostat housing to the auto box to see how the temp goes on that for towing, any ideas on where to fit the sensor would be appreciated.
I hope the info may be of some use to anyone thinking of fitting either the engine watchdog or scanguage. Pete.
