Ok well I got new resistors for my injectors. Completly redid all my wiring. Fitted my injectors better. Routed in my Intake Air Temp Sensor, made vac sources off my charge pipes for my bov and wastegate. And have my boost gauge T'ed off my FPR. Checked for leaks and cant find any. Ok well car starts, and idles at like 200.. flucuates to 800. And vac is around -10.. and goes to -12-15 during sputters. The car is running hella rich. My settings are on the smc -47 for idle to 1.5k -46 everywhere else. Even set idle to like -55 and it still rich as ----. It just wants to keep bogging and dying. Now I have a fuel pump cut off switch. If I turn the pump off it holds -20 vac. and idles fine. But dies out after a few mins (when fuel is gone). I really need help with this. I've been on this for 3 weeks and nothings changed.

My setup: 14b, hf manifold, adapter plate, dsm black tops, 10watt 10ohm inline resistors, smc500, o2sim, dsm 1g bov, stock fuel pump, stock fpr.

check the impedance on the injectors mabey some are faulty


i duno the range it shoudl be in ask mitsubishi

Only thing is I knew who owned these before me, and they ran fine. =\

how did u do the o2 sim.. could be tricking the ecu into thinking its lean and dumps extra un needed fuel.

Or maybe the intake air temp is reading hotter then normal intake temps because of the turbo.

pinched fuel return line somewhere?

any fuel pressure guage? cheap info available w/ one of those, good for diagnosing things.

The o2 sim has been on the car for a really long time. Intake air temp i dont think is causing it. And im positive that theres no line pinchs.

i know the FPR is stock oem, but is it new or original??

BlinD

its original.. I'm wondering if my smc is bad. Because what happened when all my problems started I was NA. And installed my boost gauge, and smc. Set the smc to 0% and it kept flooding it out. Maybe I should go afc.

88crxSi

who makes the SMC? greddy? Also is there a setting that lets you bypass the smc settings and make it work like is not even there ?? like a pass-thru option?

Try taking the smc out and see what happens.

maybe your FPR is toast aswell?

it sounds to me like that smc is just junk. if it started na and the only mod was that and the boost gauge then it has to be that.. either its not wired up right or its just defective.

I can't believe your still dicking with it.. FWIW my car is still running like ---- also.. I'm waiting for some more chips to get here and a wide band to tune it. I suspect its running rich and fouling out the plugs... it runs great when I install new plugs and weeks or so later it starts to studder and gradually run worse.. Thing is when I pull the plugs they look great.. I think the 02 sensor is letting it clean them up when its just cruising along.

Todd. probably. Well yeah it in my mind is the smc. I've rewired the thing like 4 times. And the wiring is perfect. Injectors have been rewired and they seem the same. I have a feeling its the smc. Because everyone says at 0% it runs like stock. Well 0% was flooding. Heh. So I guess I need to invest in a AFC. I really need my car back. 1 month no car = . Anyone know how much they run new? I dont really want to ---- with used ---- right now.
