minus 10PSI i.e. not on boost, just crawling. For some reason the best I ever got from her was 20mpg and pushed you could get that close to single figures.

Srukk sge gas gone now so nothing much I can do about it

Should be ideally 14.7:1 on a cruise, you could even go leaner.

What type of gauge was it though Wocketfast, a narrow band gauge will indicate too rich even at 14.2:1?

it was my innovative motorsports wideband Martin.

didnt sell the wideband with the car

only put that in to see what results I got, then I switched it back to the narrow band for everyday use. Didnt want to kill the wideband sensor by running it all the time, and its not the smallest meter ever so finding a perminant home for it would have been a little tricky :P

30PSI - yup she should have been running 14.7:1 but just toddling along off bost she was 13:1. the fuel economy was definatly not what it should have been, and now Im wishing I had got a fuel pressure gauge and checked that too.

Never mind though, I've done 70 miles on the first 1/8th of a tank in my Primera, and the insurance was a whopping £456 cheaper. Oh and she has a proper old man towbar with dual lighting hook up, track day tow car anyone

Oh i see. The LM1 is a bit large, my mate has it. Whats annoying is that its pretty much an empty box when you open it. So I decided on the vems one.

But its good to have a wideband that can be easily transferred from car to car

I would like to get the exhaust probe adaptor for it, and the RPM adapter so I can log RPM, AFR voltages etc in the future.

One day I may have an S12 again
