i heard in France that it's very dangerous for the motor to use grey on cossie, because you will be too rich at low rpm, so the fuel wash the cylinder and damage the block
and also, they said that it's a not a good idea for road use

what do you thing about that

bollocks, basically [/Dave mode]
















[Not Dave mode] Its called borewash, but most tuners can supply software that control decent levels of fuel low down in the rev range [/ Not Dave mode]

 

PMSL @ Dave Mode....

 

Greys are tiny by todays standards, we now do injectors twice the size that will run teh same emissions yours do now, namely, 0.3% at idle, cruising everywhere at around 15:1 with no problem at all. In fact, ive got my own car running well at 16:1 at the moment.

There is a topic somewhere that may help to explain what you need, i will look for it and BTTT it for you.

Stu, why have u gone for 16:1? As isn't 15:1, or just over, best for economy?

 

Peak economy value varies somewhat from engine to engine, just want to try it for a week or 3, just because i can TBH.

 

Fair play.


THE POWER OF STUUUUUU.

 

Thought as much I'm going to fit the fuel computer in, so can compare the AFR vs MPG
