Re:440's and turboedit PM6 installed, car not running?
 

ok,

on the aem adjustable regulator, with the 440's installed and the chipped pm6, car wont run. with the aem adjustable regulator turned all the way up, the lowest pressure i can achieve is 60psi.

leave the adjustable regulator in, at the current 60psi setting and run the stock injectors, car runs/idles fine. Cant get into boost though as the car starts to buck and kick.

put the stock regulator in with the chipped pm6 and stock injectors and the car is still running at 60psi fuel pressure, car bogs and bucks in boost.

put the stock reg in with chipped pm6 and 440's, car will not run?

any clues guys? im lost here

Re:440's and turboedit PM6 installed, car not running?
 

your regulator is defunct if you can only turn it down to 60psi...you need to be able to lower it to 41-48psi.

Re:440's and turboedit PM6 installed, car not running?
 

the pls tell me how to turn down a stock regulator?

it aint possible to my knowledge.

as ive said, im not running the B&M unit at all right now.

current setup is stock injectors, stock reg and turboedit pm6

Re:440's and turboedit PM6 installed, car not running?
 

Are you running the HP Walbro Fuel Pump?

I have the B&M regulator and the regualr 255 ltr/hr pump on my car and my fuel pressure with hose off the regulator is ~45psi.

I would hope on the AEM it allows you a much greater range than the B&M and allows you to turn the fuel pressure down to where you need it.

You can't adjust the stock regulator unless you have the B&M and have altered it :-\

Re:440's and turboedit PM6 installed, car not running?
 

so far ive tried:

AEM reg
altered stock reg with B&M hack
2 stock regs.

none of them will allow me to drop base idle fuel pressure below 60psi.

something is hooped here, lol.

ill keep fighting with it and see if i can come up with a solution.

until then, any suggestions are more than greatly appreciated.

Re:440's and turboedit PM6 installed, car not running?
 

oh and in regards to the walbro pump, its sitting on my shelf awaiting install.

not going in until i can solve this fuel debate.

Re:440's and turboedit PM6 installed, car not running?
 

where have you tapped in for the fuel pressure gauge? is the fuel pressure gauge accurate, have you checked it against a known pressure? it sounds impossible that so many FPR's are not working correctly

Re:440's and turboedit PM6 installed, car not running?
 

gauge is tapped in at the fuel filter.

gauge kit is the B&M fuel pressure gauge kit.

Re:440's and turboedit PM6 installed, car not running?
 

maybe your return line is clogged??? ???

Re:440's and turboedit PM6 installed, car not running?
 

gonna try a couple of things.

the car was originally a 1.5 DPFI, and apparently one of the fuel fitting holes on the filter end are smaller than the 1.6's and could be increasing flow???? its a far fetched idea, but possible.

im gonna replace the fuel filter to see if that changes anything as well.

also this car was a 4dr 1.5L LX. now a 1.6, but talking to a couple of buddy's of mine that are hondatechs, they were telling me that they came across a similar problem with a supercharged EG coupe and the prob was a dual feed fuel pump? now i dont know what the chances are of my car having a dual feed pump and could be causing the higher than normal pressure.

??? haha i dont know, like i said, its a far fetched idea but it is a thought.
