Ive Got 54% better mileage now!

[smokingwheels]

Hi,

Im back

I do like reducing my fuel consumption by 54%

I have that dam engine runing ok now.

I have found I need sum 30 degrees vac advance, with cold air

Still few things to sort out yet (another 200 hours+++)

Im looking for a computerized ign system.

The mega squirt system only goes to 50 degrees BTDC

Ive emailed them a month ago and no response yet.

I will need to have an basic offset of over 70 degrees BTDC (even higher)

and the ability to fire as late as 14 degrees ATDC.

?????? Does anybody know where I could find such a beast?????

I will start porting the Z engine soon.

My PC based system is ok, but its only for tunning an engine.

I have still a bit more programming to do

so that I can tweek the main timing curve in time it takes for 10 sparks to elapse at any rpm.

sum stuff n results

2.0 L Stocker early 80's setup in a wagon with

Porting by me.....

comp ratio 10.5:1 running ULP (will try BP 98 later.)

43.7 MPG taking it easy @80 to 90 km/h and climbing 800 feet over 200 kms

Unconfirmed return trip ~50 MPG

Thermal efficiency ~61.3% if I did the figures right !

I dont know what your smoking.. but its viscously attacking you

Advancing too much = pinging and a ruined, overheating engine

In case you didn't notice we're in australia buddy. We don't use miles or gallons here.

Come on guys, you're giving him exaclty what he wants. Responses. I can't even see his post since he's on my ingore list. You do recall some of his previous topics? IMO, just let it drop right off the front page.

ok so its around 5.5L to 7L per 100km on the hwy with carefull driving.

and can use ~1.5 L /per 60 seconds at the top end

Its an experment in the boundry layer of air.

spark plugs do tell how an engine is running?

have a look at these plugs with stock dissy.

Ive att the current timing curve too

my sparkplugs are running a little hot but there 3 heat ranges up from STD,

my pistons still are black with carbon so im in no danger there.

oh and the flow tests dont show much resistance in the whole induction system just look at the timing curve at 3000 where most engines flatten out

cheers
