no,from memory they have a t,map sensor on the inlet manifold,a small black plastic sensor (about 1x2 inch ).

Any idea where? I am fitting a flashlube kit (drips small amount of special oil to lubricate valves while running on dry lpg) and was wondering if it would contaminate the MAF is inserted upstream of the MAF. Whats the difference between a MAF and a T,MAP?

MAF - Mass Air Flow suffers a lot from contamination and measures the amount of air being sucked in by the engine.

MAP - Manifold absolute pressure - measures pressure inside the intake manifold not air flow and doesnt suffer from contamination problems.

I dont think the MAF would like flash lube oil as it is similar to two stoke oil, and the very sensitive MAF sensor sits directly in the air flow.

arh, so if it has a MAP then should be fine
