When burning basemaps, do you have to set it up for walbro 255 lp/h fp's too? What i mean by this is when Rocket from Hondasaver burned the basemaps, he asked me what i had. I told him that I had a b16a, 450cc's injectors, etc., but I didn't mention the fuel pump because i wasn't planning on running one. i got the fuel pump after i got the Hondata and it seems like the car is running way too rich (and i also rewired the fp w/ a 10 gauge wire).

 

There isn't such setting parameter for fuel pump. However, you do need to specify injector size and static fuel pressure. Most likely your static fuel pressure has increased with the high pressure fuel pump. If you have an adjustable fpr, simply set it back to where it used to be.

 

I have witnessed that fuel pressure will increase by 4-5psi with the walboro units. The fuel pressure is around 42-43psi at static.

 

will i be able to trim down the fuel w/ the hondata or will i be needing an adjustable fpr? how are b&m units? i was told that you can only raise the fuel pressure and that's not what we want to do right?

 

you can lower the fuel using hondata, but to adjust idle fuel pressure I would get an adjustable FPR
