Your best is pretty decent for a 102, but how the hell did you get 11.87? Even when I flog mine I can't get worse than 10 Those best and worst are probably slightly biased, just had a better look and they are both on smaller than normal amounts of fuel. So best probably more like 6.75 and worst 11.5. Lots of short trips with engine cooling down inbetween is the key to bad fuel consumption, add some hills in on those trips and it becomes really bad! What sort or numbers do you get Hiro Protagonistt?

Looks like to diagnostics port only gives errors codes and access to some fault finding/testing functions accoding to the Gregory's service manual. So I would say that scangauge wont be any use. Will have to try building one myself, I will keep you all posted on how I go (I'm an electronics engineer so shouldn't be TOO much trouble, hopefully!). Anyone got suggestions of things I should include? For starters I will be measuring the pulses to the injectors and the speed pulses to let me calculate fuel consumption. Later I think I will include measuring all signals to the ECU and having a data ouput to a laptop. My plan is to make a device very similar to the Oztrip meter.

Hi Guys, Will call the Aus distributer of Scangauge tomorrow to see if it is compatable. How can I find out what info the "Diagnostics" port in under the bonnet transmits? Anyone ever used it?

I have a 1999 7AFE AE102 Seca. My average over the last 50000km is 8.5L/100k. Worst is 11.87L/100k, best is 6.5L/100k.

For such a new car surely it would be better from a money point of view to sell yours and buy a manual. You will be around the same out of pocket, and you then have an unmodified car which is then worth more then the modified one, so you are actually infront. But if you are going to do other major mods then I guess you may as well convert your current car.

Hi All I am planning on installing a trip computer into my corolla (AE102 7AFE seca) but I am having trouble finding anything suitable. It looks like there used to be an Aussie made system called OzTrip but it doesn't seam to be made anymore. Can't find any other similar devices out there either, they are all OBD2 tools which I am pretty sure my car doesn't have (please correct me if I am wrong). It does have a port labled as "Diagnostic" in under the bonnet, can I get any useful info from this. Basically, what I want is a system that calculates fuel consumption as I drive. Does anyone know of a suitable device? The OziTrip computer used the injector duty cycle and the vehicle speed to calculate this. So worst case I might have to try to make something myself. Thanks for any help
