Button,
My experience of fitting EFI to a Lotus Twink is this.
Power (BHP) gained (or lost) by fitting TB's vs Webers is zero.
Torque (FT/LB) gained from the ECU mapped ignition vs worn dizzy is lots.
Torque (FT/LB) gained from the ECU mapped ignition vs good dizzy is some.
Driveability gained from fitting EFI is lots.
MPG gained is about 4 mpg.
I would also add that any of the ECU's that give you the features that you want will perform well. The key is the person who does the mapping.
The best ECU poorly mapped will be crap and the worst ECU well mapped will be good.
Cheers
John
PS would love to fit TB's to my +4 when funds allow.
Thanks! Which +4 do You have? If it is a Zetec or Duratec, why do You think a TB would improve the performance?
