Do i have to increase my fuel perssure

[PH430]

Do i have to increase the fuel persure to 3 bar when i switch over to the Vectra injectors to match the Mark Adams chip.

I have fit a 20AM AFM with the MA chip. After switching to the Vectra injectors the long term fuel trim is +100% on both sites on Rover Gauge.

Thanks for al your answers

Was it a best guess map?

Normaly the map is for standard. Injection, so i e-mailed Mark. He said that the 14cux will do the rest for matching the vectra injectors.

I think the vectra injectors have a Total different spray. At idle they have less than the standard injectors an at high revs they have more.

With the vectra injectors in place and 2,5bar fuel perssure, rovergauge reads +100% long trem trim on both sides.

On 3bar the vectra injectors do 250ml, and what at 2,5 bar?

Hi OP, not sure why you are putting all of these new bits on the car?

the 20am needs to have a different scaling on the map to the 5am. Has that been factored into what is on the car?

The chip from MA is mapped for the 20am to my 430, only for standard Injection.
