i just turbo'd my civic coupe with a b18b and custom turbo kit..
for my fuel management im running with a 12:1 vortech FMU, Missing Link, AEM FPR,STR fuel rail, and B&M fuel guage on 6.8psi of boost on an external tial 38mm wastegate.
yesterday i cranked up my motor and everything went smooth, retard the timing, and i hear no signs of clickling noise around the engine so i was set to go. i then took it for a test drive and everything went smoothly, not reving over 5k's. My B&M fuel guage is rigth on top of my fuel filter and set was set at 43psi without the str rail and now 40psi with the rail (it went down by itself because the rail was huge)..
after a test drive, came home and decided to put my inline fuel pump on (researched and was a must for FMU set up) afther testing the inline fuel pump after connecting it to my main relay 12v (yellow and small green line) put it on start and checked if it was working on or not, 2-3 seconds of clicking and off. looked at the b&m guage and it went down to around 30psi's. i then turned it off and turnd it back to on and it went down to 5psi's on my b&m guage..

so then after... i cranked the motor up and the guage is now at 65psi's and the inline fuel pump working perfectly, i knoticed that it was running rich so i turned the fpr down and maxd it out at around 55psi's.. idleling pretty good but was petty rich

i was wondering if i should ditch the aem fpr and just used a stock one? have anyone had this experience? im going uberdata soon but for now fmu set up with all of the above.. i didnt want to drive my car rgith after i put on the inline fuel pump, and was wondering if it would be safe to drive with my fuel set up

thanks

at low boost levet you can stick with stock pump and FMU, level the FPR at stock setting and take out the inline pump.

thanks, thats what im about to do, but then dont the fmu require the inline pump to function properly? 6.8psi is pretty low but then again will my motor lean out on boost without a inline pump?

Get a 255 walbro in tank pump, even at low psi you need a fuel pump, the stock one blow ***.

even if i get a walbro, will it be safe enough? im goin crome/uberdata soon and need a temparay fuel set up as for now. i know i can keep the walbro, but ill get rid of the fmu/missinlink/inline asap once im done tunning with uberdata/crome.

btw. are there really bugs on uberdata?

if it blows that bad why does most of the people using uber still have the stock fuel pump. i even asked if i should upgrade it n everyone said the stock one will be fine. i kno it wouldn't hurt to have it but 6psi... i think he could pull that off with out anything =x
