can you set the rtek to run a 850 and 1600 injector setup ?

 

No, but with 2.1 there are presets you can use (550,550) (550,720) (720,720) then you can dial out the excess fuel I'm running 680cc,1000cc on the 550x550 setting and seems to be working out pretty well...

 

has anyone used a 2.1 with 550/1600cc? I would like to know if i can do this temporarily because i need to stop hitting fuel cut and already have the 1600cc injectors ready to go in. I will eventually go with a Haltech

 

ive tried 750/1600 but couldnt tune out the stumble at transition. ran ok in boost though, had to use 550/720 preset and take a lot of fuel out

 

with my old setup I ran 720/1000 with the 720/720 preset and it worked great, no stumble at all.

 

550/1600 would be very hard to tune properly. You'd have to run the 550/550 setting. It would run fine down low but as soon as the secondaries come on, its going to bog. The transition to secondaries would be painfully hard to tune. Could you do it temporarily, yes but it's going to run like crap in boost so I'd try to stay out of boost while it's like that.

 

the rtek 2.1 has an fcd you shouldnt be hitting fuel cut

 

i currently have 550/1600s and it is horrible at transistion. if your motor can boost past it then it's not too bad but it will spit and sputter all over the place.

 

I also run 720s and 1000s on the 720 720 setting without any problems but i pulled alot of fuel
