Will my Evo 9 FQ-340 need a new fuel pump before a remap

[D1andonlyantman]

Hi. I was wondering if my fq340 will need a new fuel pump before remap? I read that the fq360 comes with an uprated pump and I was wondering if my 340 does?

Thanks.

Yeah its advisable to uprate the fuel pump. A Walbro 255 is good enough.

Agreed

Cool, thanks. Also I've done the airbox mod, is there a decent intake pipe that will go inline with that? Also I've been told I'll need a boost controller. Any recommendations?

Thanks

I never bothered with a boost controller, a 3 port electronic boost solenoid should be sufficient.

eg:

Sorry mate but what's the difference between that and a proper EBC?

 

[Simon@NTS]

3 port is ecu controlled

 

[D1andonlyantman]

Ok, I've just done a bit of googling and what a boost controller does makes sense. Once you start modding and mapping the boost could get a bit erratic so a boost controller helps keep it constant. That makes sense. I really doubt I'm ever going to track my Evo but do take the car out for a good thrash, so do you think a solenoid is enough or I should go all the way and get a proper EBC? I don't like to take shortcuts but I'm not made of money so wouldn't want to buy an unnecessarily complex bit of kit.

Thanks

Ecu boost control is very good, ebc £200+, 3 port £50+

I'm going to got gauges so I can see what's going on, but I can't see me ever adjusting the boost. When I get it mapped the tuner will set up the boost as well as the AFR won't he and there will be no reason for me to fiddle with it?

 

[Simon@NTS]

Yes and no reason to fiddle

 

[D1andonlyantman]

Awesome thanks. I'm going to order that i think

I can do you a MAC 3 port for £55 delivered comes with fittings

To be honest because I'm doing so few mods before remap meaning my budget isn't so tight, I think id rather go with something like the grimmspeed just was recommended by other people, for peace of mind. Plus the Grimm is plug and play which sounds a bit better than splicing tbh

Depening on what you want from a boost controller, if money is tight then you could also look at a dawes device or similar. cheap reliable and easy to fit.

Tbh mate I'm probably gonna go with a grimmspeed EBC if I can get one for a decent price in the UK, and if not the people who are going to map my car sell EBC's they fit on the day. Cheers tho
