hahahahahha. You guys thought I was talking about dragstrip times, actually Im finally below 10L per 100Kms. After a year of trying to tune my quad throttlebodies with my ancient haltech F7, I can tune them using two fuelmaps. One for TPS and one for MAP sensor.

For those of you that don't know, the halech F7 has only a MAP sensor for fuelling. Quad Throttlebodies have only a small source of vacuum. So just over 15% throttle the computer sees wide open throttle, then delivers maximum fuel. This means even while cruising it runs as rich as giving it a beating. Good for track use, BAD for street

With the megasquirt. It can run two fuel maps so it is now drivable on the road. and Im back to 10L/100Km!!! With tuning I will get carb economy, with whoopass response and power!!!

Just done calculations 23.9MPG for you Americans. Thats with a mystery cam (lumpy), and portwork done, A14

are you the guy running the R6(motorbike) quad throttle bodies?

And yes i thought you were talking about ETA on the dragstip!!!! lol

yeh. and the A series is the perfect engine to learn on..... It has taken abuse for the last year, MEGA rich, MEGA lean. even one case where the timing was locked at 44deg under load above 3000rpm. PING PING PING. Very surprised that it didnt detonate.

I dunno what it does down the quarter mile. wouldnt mind findin out thou.

My 78mm bored a15 with quad mikuni 40s used to get 25-30mpg
until it cracked one of the bores.
I used to also have a Honda coupe 9 that made 115hp and gave 40mg.
Im not questioning the response and smoothness of FI just that
you should be getting close to 30mpg for a worked one and halve
litre demon.

so liam
have you got some way of seeing what your afr's are?
very hard to tune without the right tools
a mate has a microtec wideband i may be able to borrow

Dude where did you score the megasquirt? I`v been tring to get hold of one of these for a few years now, but it seems they are only avalible from the U.S
Is there any Aussie agents?

I got the megasquirt from www.DIYAUTOTUNE.com. They supply it in kit form or complete. I built mine. They provide great instructions on megamanual.com. The kit is made easily as long as the instructions are followed word for word. I also built my O2 sensor from www.techedge.com.au. It works great!! Gives me a lot of feedback for tuning. I filled up today and got 8.15L/100Km. all the credit to http://77e21.info/mstuning.htm, this guy has given me a way to tune the throttlebodies without compromise.
