Dieselllll

[Pir0]

A friend of mine has a digital dash in his Nexia. But he's recently put a diesel lump into it, and as you may know, there's no coil to get a reading for the rev guage off. Anyone know any ways to get the rev counter working?

We also noticed, only revving to 5000 rpm is bad for motor way runs, as it's on a normal f18, which is a long ratio box, but it's at about 100mph when the diesel engines running outta steam, at up around 5k rpm.

i toped my diesal out at 110mph bear in mine it's a 93 reg, a 1400cc ish and only had 50bhp when it come out if the factory

don't wot rev's is was doing as it didn't have a rev gauge

[Pir0]

Aye but your gearbox on the pug was suited to the diesel, they must have a longer final drive seeing as most diesels only rev to about 5k rpm.

how is it bad for motorway runs the speed limit is only 70 mph

At 70mph it's still running at a higher rpm than it would be with a gearbox suited to the diesel, aka 4000, instead of 3000. And it's constantly on boost at 4000.

i under stand now
i can't tell what revs a was doing

Many of the diesel engine use an optical pickup for the rev gauge. There may me an aftermarket kit available...ideally it should have adjustable output to sync it with the proper pulses factory gauge requires.

It's not a factory dash though. It's a digital one that was only used in 4 pot petrol engines.
