whats the largest size injecters the rtek1.8 and 2.0 can handle??????

 

based on my experience, rtek 2.0 has pre-sets for dual 720cc's and i thin kthat your best bet would be contacting someone from the company

 

Rtek 2.0 can lean up to 40% from stock fuel map (25% 720cc injector preset + 15% user setting). so theoretically it can account for 40% larger injectors from the stock 550's.

So that would be about 3667 cc's of injectors ((550 x 4)/60%), or say 720cc primaries and 1000cc secondaries (3440cc total)

 

can i run 720ccp and 1000ccs with the 1.8rtek and get a safc, cause they say u can run higher then 720cc but need a fuel controler, ???????

 

rtek 1.8 is controlling 4x720's as is.....so, yes, you can tune down 1000's in the secondaries with an safc.

 

how about 720 prim and 1680 sec?? can i use a rtek 1.8 and a safc

 

you probably could, but you'd gain 50 more hp with stand alone.

 

If you are going to buy the 1.8 AND an SAFC why not just spend a few more bucks and get the 2.0. You can do all of the fuel adjustment and so much more with it.

As far as the 1680s, you can shoot off a message to the guys at digitaltuning, they are pretty good about getting back to you right away. Might be pushing it though......

 

overkill on those injectors sell them..... dont know why the rx7 world is obseesed with big injectors i have my injectors running at 51lbs of pressure.
