EFI vs Carbs economy, are u having a laugh.......!

so what we're saying is that the injection system squirts 1/4 of the required amount each time, so by the 4th time round (when the valve opens) there is enough fuel waiting in the head to burn at the correct mixture?

if thats the case then i can accept it, ok its not the best, but its simple and it works.

IF the injection pulse each time is 1/4 of the necessary amount for one igntion cycle then its actually quite clever and simple.

IF the injection pulse is the correct amount each time then it is wasting exceptional amount of fuel.

i wonder which is which.

perhaps a megasquirt wizard could tell us? he would know what the injection pulse is at WOT on 14cux, and on megasquirt. the megasquirt pulse duration should be 4x that of the 14cux.

cheers

Good question mr nos!! might be worth i new thread.... Very interested to know. How rver the last MS system i looked into fired the injectors in groups of 4 just like the CUX

URGH!!!! What is the point of a £600 quid system which uses a crank position sensor if it still bank fires?! I am suprised/horrified!!

Dont get me wrong, it can fire the injectors independently but that requires a new loom, and sometimes a higher spec'ed MS unit depending on what else you want it to do. So from what i gather most people just use the same loom and have it fire banks of 4 injector and wasted spark ignition.

But yh, to answer your post, it is capable of fireing upto 12 injectors independantly if so required.

Ah I see. Cheers mate.

Well I have to admit I'd be well up for making up a loom to fire sequentially, as far as I can see, bank firing is a MAJOR reason behind poor economy.

One day in the far away future I'll be after a megasquirt kit, and I'd do everything I could to make it as capable as possible.

Cheers for clearing it up pal btw

Yeah, im gonna go MS ASAP cause by the time i buy the correct dizzy, then sort out all these hotwire niggles its gonna have cost me nearly as much.

One thing that has come to light after all this bank fireing talk is: it now makes sence wehy it takes so long to run back down to idle after reving it hard. Probably cause of all the petrol sitting around in cylinders which no longer need it after the pedals been lifted...... Do you get my thinking? At the point when you release the throttle half the cylinders will have 3/4 of the fuel they need for full thottle just waiting, and its still gotta be burned. hmmmmm......

MS looking more and more appealing everyday.........
