also sounds like you need to back off the overall pressure some more. turn the center screw out. you should cruise at stoich.

fuck the fuel gauge. I've said that before, right? They're known to be inaccurate. back down the center screw and watch your wideband.

the center screw is almost all the way out, still at 13ish cruise. running fairly decent now . still gets really rich up top. i will try the duel check valve and see it if helps
|
no it won't help your cruise
did you f-up your afm flapper position? if everyone else can cruise with those injectors, you can too. |

maybe you'll need to adjust the arm to the lean side. wierd :dunno:
they're high z injectors right? you verified the o2 sensor is working? another member also had an odd issue like yours. his ecu just stopped going closed loop. his problem was fixed when he replaced the ecu. |

buy a fucking megasquirt
:inout: |
lawl...don't you know how to solder them up bryan?
|
takes less than an hour.
|
actually had one on my probe. i dont want to go into all of that again. i just wanted a simple, no frills setup on the miata.
|
305cc injectors, RRFPR, check valves, Walbro 190HP, Bipes, O2 clamps, and you still can't tune it perfectly
vs. 460cc injectors and an MSPNP Who's got more shit bolted to their car? |
oh shnap.
|
I would check the NB o2 sensor with a volt meeter, you might learn that the thing is shot, or that your WB is inaccurate, or nothing at all.

put in a new narrow band, no difference. i have 100miles on this tank of gas and i only have 1/4 tank left. i think i will just put the stock injectors back in
|
I don't know if i am correct... But how do you think the ecu is handeling injectors that are 50% larger than stock?? Normally very rich...
So you need to lower your base pressure below oem levels... The only way i could think of is to make a bypass between the fuel suply and the fuel line between the afpr and the fuel rail. In the bypass you add a adjustable restrictor so you can adjust your static FP below stock levels.(tune that on your wideband) At boost the afpr takes care of the rest... |
they are only 30% larger and it can be done. I did it for over a year and made 240 miles a tank, consistantly.
something else is going on. you should be able to lean it out enough with just the idle mixture screw on the afm and it should be golden. |
