TPS & MAP setting on aftermarket EFI system

[William Shurvinton]

Sure cheaper than NEW webers, but who buys new on this list?

Of course if you don't oen a laptop, EFI becomes quite expensive ;-)

If you ever make it as far as the M3 give me a hollar, I'm sure I can help
you with button pushing.

Hi Bill,

I couldn't agree more, I guess it's just a foot in the
door really. Even badly set and hideously rich, the
engine runs a thousand times better than it did on the
solex, stromberg or weber twin choke. Besides, the
actual ECU cost about £120 which is less than a pair
of new webers.

I had a play with resloping the map column last night
with good results, I have managed to get the engine
slightly rich at all points (previously lean at high
vacuum and way rich at low vacuum) and the speed
column now looks like the VE map that it should,
increasing towards peak torque. Just need to pull all
the values down a bit now and it should work a lot
better. More importantly, I could do with a passenger
capable of playing with the laptop whilst I drive.
It's a bit dodgy driving round central London doing
this on my own!

Cheers
Dave
