So i've searched in the forums and by google and i have seen nothing pertaining to tuning after installing a walbro. what should i be paying attention to on evoscan when i'm logging. should i adjust injector scaling, latency, etc.?

 

have it tuned by a proffesional. just by your question you need to understand what changed with a fuel pump install and if you dont understand that then you definitely dont need to be messing around with your tune.

 

Lemme take a shot at actually answering your question. Chamelieon is right though, no offense, but your question scares me. Scaling and latency values are related to your fuel injectors. You didn't change the injectors you changed the fuel pump. So to answer your question the only thing you should change is your afr map, fuel map, whatever you want to call it because more fuel means it will run a little richer. But I'm going to have to agree with ^^^ and you should not just go changing your fuel maps without any idea of what you are actually doing.

 

^^^ This, increased fuel pressure richens the mixture-- it maybe noticable or it may not, no need for an immediate tune or adjustment by you. Add other mods and take it all in at once. Good thing is your richening up your mixture while with most mods tend to lean things out--

 

I appreciate the advice but it's not like I plan on trying to tune my car tomorrow. I'm asking these questions for future reference so I can learn to do this on my own. I'm patient when it comes to something that could cost me much more down the road.

 

That's a good way of looking at it. A lot of ppl install 255's without a tune. It's not the worst thing in the world and the fpr will handle the extra flow for the most part anyway.

 

you will be fine without a tune. just get some more parts then tune.
