I am looking at upgrading my secondary injectors and am in need of advice as far as what I should use cc wise and also what any suggestions would be for gear to use. I currently have a pettit unlimited ecu with fulll exhaust and all the normal bolt ons except for Fmic which I will be installing shortly. I thought Jay (TurboVr6) did write up on his install but I havnt been able to find it. Oh yeh I already have a supra TT pump. Thanks!! https://www.nopistons.com/forums/pub...IR#>/bigok.gif

if you want to put larger secondaries..... i'd go for the 1600's and a powerFC. if you want drop in's you can get your 850cc bored out to 1300cc.... i like the idea of brand new fuel injectors though
|
Does anyone know exactly what a Pettit unlimited is tunned for/to?
I thiough the standard upgrade was 850 primary and 1600 secondaries.. |
pettit unlimited is tuned to every bolt on upgrade and ported engine. it basically runs the stock fuel injectors up to 100% duty cycle so it won't lean out!
most people go 550/1600's i went 750/1600's....... |
So what do you guys think of me using 850's primaries and 1600 secondaries? Also does anyone have a good write up of installing regulator and braided lines with fuel rail? Thanks Ps the reason I am persistant on using 850 primaries is because my 550's are leaking right now.

if you buy keith's rails you can buy brand new top feed injectors CHEAP
|
Im awaiting a reply from pettit so I know what the capabilities are of my ecu. That is unless any of you are certain and can share some info https://www.nopistons.com/forums/pub...IR#>/bigok.gif

pettit's ecus cant adjust for bigger injectors
|
So pettit says "unlimited" but obviously there has to be mods you cant do under ecu limits. Anyone know the extent of what i can do with this ecu?

they are brand new factory 850cc bored out.. so in essence..they are brand new injectors.. pending on your application.. 1300cc can provide enough fuel.. considering youve mapped out your pump and regulator to adjust.. |
