Hi All,

Good to be here - I've always been interested in ecomodding - to the extend that I've even been involved in Solar Car racing.

Now I've bought an old banger E30 BMW 6-cylinder - and I honestly was not prepared for the fuel consumption - I didn't think a 2-liter could do this.

I'm looking at 7 km/liter - where 15 km/liter is what it should do, IMHO.

So - to work - this is the plan:

Lean out the mixture - (open loop control - no issues with Cat Converter)
Ignition Timing to current fuel grades
TC lock-up at low speed
Cylinder deactivation - running on less rather than 6 - gets a bit more complicated since I want to alternate the cylinders which are off and on, and have a range of options at hand to miss beats here and there, so to stay to WOT as close as possible.

Cheers - Joshua

wish me luck...
