I have an MS2/extra and when i turn on main power, i hear the fuel pump turn on and prime the rail. Sometimes it will build all the way to 43 psi depending on how long its been sitting and how much pressure has bled from the rail. Other times, it barely builds 30psi and i have to turn power on and off to build enough pressure. Is there a way to have the pump prime for longer within tunerstudio?

 

I think that the priming pulse table is under startup / Idle. Pg 160 in the tuner studio manual.

 

Thanks for the reply. I think the table you refer to is the priming table for engine start up and the ms the injectors fire for.
I am looking for when the fuel pump primes the rail during initial power up, if that rail priming time can be increased.

thanks
