Default for link guys with 255 lph fuel pumps....?

how far did you turn down the master fuel?...I'm trying to get a rough estimate.
if it helps I'm have only an intake cat back exhaust...soon to gut the downpipe...

thanks, Micah

What is master fuel? Is that an ajustment on the pump itself? Sorry, I'm a noob when it comes to fueling mods.

doesnt it say in the manual somewhere to keep your master fuel over 100?? if not i know ive read it somewhere. my laptop is in the car right now and im way too lazy to go get it so im not sure exactly what mine is set to but i think its around 120.

I'm just saying to lower the whole map because of the larger pump...instead of having to change each block

lower it to what?? instead of going below 100 i would just lower everything else. and you dont have to lower every zone, you can lower it by rows so you just have to lower 10 rows, not very hard at all.

First off are you running bigger injectors?
Is this a WRXLink or A Link Plus?
What is the current value set at?
What is your A/F ratio at idle currently?

I have tuned over 100 Links so these are the questions I usually ask when someone is looking for what to do. Answer these questions I bet you will find the help you need on the boards.

stock WRX injectors, WRX link, and just asking a theoretical questoin to see if people do it this way...I guess not...I'll just have to lower it each block at a time...
Thanks guys, Micah
I have a 255 lph fuel pump...that was the reason for the question.

A good easy way to lower it is to try this. Turn the car on, while it is warm, then let it idle for a minute. Now start lowering the mast er fuel level till the point it is abotu to die on you.

Once it is about to die raise the value up about 5-7 points and you should be all set to go.
