How 'clever' is digifant??

[gizago]

Ive got a 2 litre bottom end on my mk2 8 valver, with a fast road cam and exhaust. Ive got hold of a big valve flowed head, a hotter cam and a 4 branch manifold. Is the digi management system clever enough to 'learn' this, or is it worth a re-map or getting hold of a motorsport chip??

Are there any bigger injectors that can go straight in or is it not worth it??

No, K-jet is dragged along on a rope behind the bus, because it won't mind.

Cheers for the help guys
Anyone got any actual answers to the questions?
I've built/ tuned / modded plenty of carbed motors over the years, but have never really played with injection. I know digi isn't great, but will I need to do anything with it or will it just plug and play with all the other mods?

It'll plug and play and give you flat spots where you don't want them and lean out at the top so you grenade your motor before too long, probably.

You've given it a bunch of stuff outside of its specified operating parameters.

It doesn't do learning, it does looking sh*t up in tables and giving things values according to what it finds in the tables.  If it's outside the table values it just gives the bottom/top value and you'll f*cking like it, ok?

Go custom remap once all in its likely with those mods you will not fully use them without proper full remapp! Emerald spings to mind not sure if they are still in business though LOL!

I'm sure there is a off the shelf ECU (plug and play) you can spend your money on.
I like K jet it sucks in as much fuel and air it wants, at expense of fuel and emmissions of course   

[Diamond Hell]

No, K-Jet sucks in some air and some fuel, mostly based on the revs of the engine and the shape of a bowl.

The shape of a f*cking bowl FFS!

Its simple and over 20 years old what do you expect?
These were designed to adjust itself as you rev harder.
I've seen decent power out of a 1.8 let me put into context its a bloody old car!!!
I like K jet when it runs right and people throw these old blocks mainly due to vac leaks.
