lol no worrys

Ive got a wicked Idea. :grin: How about instead of NOS Vs Turbo. How about Carb Vs Injection :grin: The proofs in the pudding at the end of the day.

Buy all means hijack, its all got to do with the project. Carry on sir, carry on!

I need some time to write it up, so I will post tomorrow if that's OK? Here are a couple of links to get you started....

http://picasso.org/mjlj/ Megajolt mapped very cheap ignition, built this myself for SU carbed turbo.

http://www.megasquirt.info/ms2/ Megasquirt FAQ. Remember you can't inject the 5 port A series with this unless you use a wet manifold like graham harvey does, (though he uses Emerald - http://www.emeraldm3.../em_ab_em.html).

Fuel injection basics

http://auto.howstuff...l-injection.htm

Get you started anyway!

The SU wins out over the injection on the 5 port because of charge stealing and the fact the injector has to get the fuel in in a very short window with a duty cycle of 62% max unless you use a wet system where the injection becomes just like an electronic analog of the old SU but with an infinately adjustable fuel curve. The entire point of the 7 port head was to allow the superior injection system to be applied to the A series, where you have one port per valve, batch injection is very very simple to implement.

Thanks for the links.

Thanks for the links.

No worries. Will do a proper job tomorrow!

So when is the mag coming out then in 06

[ed4ran]

Heres my megasquirt!!!


and heres the software (setup for EDIS)


You can change all the fueling, and timing yourself with a normal PC.
and with the lambda sensor its really easy!!

Yes!

Any perticular month. Or still not set?

[kada1980]

Also to add a wideband will pay for itself, no need for rolling road time unless you want some numbers to talk about in the pub :grin: :wink:

If I tell you then others will do everything they can to mess it up, so I am keeping quiet until it's printed, sitting in the distrubuters wherehouse and about to hit the shelves! TMF will be the first to know!

Well thats fine by me lol

[Engine_tuner]

Sorry for the late reply guys,

There seems to have been a few more pages added since i last checked?

The orange mini with the sequential box is owned by Nigel Hepburn (check my website)
I built the engine (full race 1380cc with a 38x32mm off-set head) and Mike (MBE) supplied the sequential box.

This runs fuel injection on the 5 port head & Webber alpha ignition with very good results, As do many other serious sprint drivers.

BUT the fuel injection system thats works on a 5 port head is very expensive.
So far i have found a 7 port head using carbs has very little gain over a 5-port.

I dont know what to do anymore so much info about the near to none improvement over a 5 port lol talk about mella drama, i think i should become a writer for eastenders or something (erh yeh right!!!)
It seems to me, im going in the wrong direction with all this. A case of (me see, me like, me want) well i will have to think long and hard. Many thanks to everyone for their ideas.
