ok so i am going to pickup my car today and heres whats going on:

The car has hondata s200b, with a base map. The car doesnt run very well right now cause its runnin pretty rich. My question is:

Is it normal for the car to not run that well on a basemap?

Also: can the fuel pressure be adjusted through hondata or will i need an adjustable fpr? I purchased a b&m fpr but the shop i got my car at said they fail so often it isnt worth installing, and hondata should be able to control the fuel pressure.

Thanks for any help, pickin my car up at 3pm EST and dont want any surprises once i got it back...

Thanks

Basemap is exactly that. Base set up to get the car running and on the trailer (if you have one) or very gently driven to a shop/dyno to get it tuned correctly.

Fuel pressure is mechanical. You can tell HONDATA in the fuel trim multiplier what your base pressure is. But other than that it is mechanically adjusted through the vacuum reference port on the regulator itself. Most good aftermarket regulators come with a base pressure that is adjustable between 30-70psi. What will raise that fuel pressure on a 1:1 ratio with boost is that vacuum reference port. Run that to a vacuum manifold (Golden Eagle) or off of tees that you have off the intake manifold.

Pro-Am, great info thanks alot.

Ok so as to the FPR: your saying i should put it on? is the b&m fuel pressure regulator that crappy?

I have a 2000 civic si FPR on there right now, should i have them put the b&m on?

Just tune it and all will be well.

your saying just tune it on the stock (200 si) FPR?

thanks!

i have personal experience with the B&M FPR failing, they suck imo. try to get an aeromotive FPR and get the car tuned. dont drive around on a basemap and DONT boost on it

Since you have the Hondata you should keep the stock fuel pressure regulator. Larger injectors and proper tuning will take care of the rest.

I do not know what your budget is, or how much you are willing to spend. But I would go with the Aeromotive FPR (that is even more so if you have an aftermarket fuel rail). There is also SX, Venom, Edelbrock, etc. I have always had great success with any of those. I have never used the stock one on anyting else but like a Greddy street legal kit. Anything bigger than that, the guys would always get the aftermarket rails and regulators.

i got the stock 2000 civic si rail with dsm 450cc injectors, walbro 255 pump and 2000 civic si fpr.


Goin to get it hondata tuned tomorro, my tuner said adjustable fpr would be best, but GSR or ITR would work fine as well.

SO how does the 2000 civic si fpr compare to the itr or gsr?

I think that the 2000 SI one will be fine for now. If you are going for the more stock side of things, then you go with the AEM one that is the stock replacement.

How much power do you plan on making? Is this motor built? If you are making a fairly safe amount of power on a stock b16 then the stock fuel pressure regulator will be perfect for your needs. I would get a fuel pressure gauge though because thats always a good thing to have incase for some reason your fuel pressure doesn't stay where its suppost to be.
