Question Install HFS-3 on DI engines - any need to connect MAP sensor?
Dear Richard,

After almost one year of happy usage of HFS-3 on my direct injection engine I have to install the same kit on the new DI car.
Can you please tell me if there is any need to connect MAP sensor to the the ECU cable or not?

I assume that only HFS-4 works with both MAP and injectors simultaneously, while HFS-3 can use either MAP or DI injectors.
Please, correct me if I am wrong; and if so - what benefits can I get from adding MAP sensor?

Thanks!
Alexey
