Hi All,
what a great site,
as the fuel situation hear in uk is getting bad (highway robbery) i have had a scan gauge sent over from the us,have set up ok and all works ok exsept for mpg or ltrs per 100 klm
i have got as far as first tank fill but the readings are still all over the place between 1 or 2 mpg or up to 9999 mpg and enythink in between,same on klm,s
would this correct its self on the second fill up?
its driving me nuts
car is diesel,ford mondeo tdci year o4

any help would be great,
thanks
john

Hmm. Gonna have to wait for the diesel crowd to get on this one. I think there are multiple settings for diesel cars but I'm not sure how to choose amongst them.

That's probably normal, if the low readings are at acceleration from a stop and the high numbers are when you're at speed. If you look at the average MPG for the trip, does it appear reasonable? If not, make sure you have the right engine size and fuel type set up. For fuel type, Diesel A and Diesel B do not refer to the type of diesel fuel, but the type of communication being used.

If it were a gas car, I'd say that the 9999 was deceleration fuel cutoff. That is a feature of many modern gas cars. Are you sure that you went through the setup procedures correctly?

The instantaneous fuel economy does vary widely on all cars. Accelerating away from lights, I can get my, the FE is low. Leaving for first drive of day, when engine is cold, a initial drive away, when speed is 5-10 mph, the scangauge will report very small numbers. If the data works out wrong when you fill up, you may want to visit the ScanGauge website for some customer support. Unfortunately I don't know much about diesel functions, so any specific setup info would be questionable.

Hi All
ok thanks for info
have done set up ok, done test and comes up on diesel b,think i got all the rest ok ,will check on av mpg,
have tried most other settings its all the same on the MPG all over the place ,will see how it is when i do the second fill and set the fuel put in,

also been told the sg2 supports IMP GAL but have not seen anything in the book ?
have seen them for sale in europe now may be the euro one is diferent to the us model,
