How to adjust pressure in ROMANO (MPI)
Written by ATK at 11 Feb 2007 10:43:29:
Hi
I installed ROMANO in Nissan cefiro 3000 cc, and I found some problem.
Every time, I drive, and rpm is higher than 4000. It will change to petrol and back to CNG. (In fact, I canceled this function in software alreadly)In my map, I found that at minimum, injection speed is around 244-245 (800-1500 rpm)
and miximum speed is around 255 (over 3000)
I think it is too much speed, and it will perhape decrease the life of injector.Now, I tried to change the injection size from A to B (bigger), but every thing is the same. And I know that reduction gear from other bands can be adjusted it's output pressure, but I donot know that I can adjust it in ROMANO or not ??. Because, It's pressure now is only about 1.9.
I am using ROMANO for 6 cyl with reduction gear (mono-state).
Thank you for your help.
