Remapping VN ecu

[Burning rubber]

Like i said grey exhausts pretty much ended once they discontinued super. Planes run similar fuel to super hence the grey exhaust. If you want grey exhaust then yeah remap your own chip and lean it right out. Once you destroy your engine you will work out that leaning out is actually a bad thing.

Such sas much wow

Leaning an engine right out will destroy it but I’m not going that far
Leaning it out is better that it running rich like no carbon build up
And like I said the car I drove, I previously drove (from Sydney to Darwin) with no problem and that grey exhaust
The same deal for the other car, same carburettor setting for 10 years now and no problems

Pretty hard to get Avgas in Australia. Even with a permit to go on airfields they won't let you fill up a jerry can, unless its aviation fuel approved container. Used to be easier to get avgas 15 or so years ago at the race track until they banned the sale.

We drain it from the aeroplane wings when we do fuel calibrations and take it home
And the only “approved container” I know of is a 44 gallon drum
Which you can order from shell or BP

Ok dude you're the expert...... Weren't you the young bloke that removed the crank pulley on his VN using a big peice of pipe, instead of a proper puller?

If I'm not mistaken Avgas 100 LL is Low Lead but still has lead in it.

Yes you can lean cruise a car and many efi cars already do this from the factory, in fact some Holden V6 engines lean out to almost 18:1 in lean cruise mode.

Have you even pulled the plugs to see if the engine is running rich?

My ute will go into lean cruise and it did that before I had a new memcal fitted.

Improvising will always be criticised
I didn’t have a puller and I barley had the money for a sensor... sooooo

But the vn isn’t an efi is it?
It’s a pretty basic motor
It still uses more fuel than most of its type
And I go lightly on the pedal


The Lead has been lowered to just about non existent

Yep, lean cruise is standard on these models.

Early VN's had a slip fit balancer and can be removed without a puller....
