Hi Dave ,
thanks for the time/performance tables at different pressure. Great job.

A bit on injectors and how they really work. The determining factor for the opening time is the drive voltage and the L/R of the injector magnetic winding.
The drive voltage is for MS appr and not 13,5 Volts and ...

Thanks for the info, Dave.

I think i'll get some differant injectors to play with but i'm still confused why a standard 2ltr cosworth YB does not appear to have these idle problems with the standard injectors.

Is you say the trend in recent years has been moving away from low imp injectors, for ...

Don't know, the car they came from was around 15 years old - Rover tomcat Turbo.

I understand wot you are saying with injector reponse time (some are better than others) but the smaller the injector the less affect the response time has on fuel flow at low RPM, normally idle problems (over rich ...

I did some testing on the Cossie injectors, and found the response of them was very poor - by swithching to more modern design of injectors (Zetec) you are proving this...

I'd find a set of injectors from a late Rover turbo with the dizzyless engine.
Despite the Rover moniker, these are actually ...

Hello,

I've been mapping an MSI with EDIS on 2ltr Turbo Zetec,

The engine spec should make 300bhp so i have used a standard set of Cosworth 4x4 injectors (330cc) running at 3bar fuel pressure.My problem is the "resolution" of the VE table and/or minimum on time of the injectors means the idle CO ...
