Is this safe?

[mr2--mad]

I a second hand afm off ----- and a new kn pod filter but didnt replace the o2 sensor (350+gst) like robin recommended .What do you guys rekon is it about average for a standard sw20 3sgte?

[4000GT]

Dont know if its normal for the motor, but its bloody rich across the entire map.

[Tukumi]

Pretty standard fuel ratios for that car, like alot of factory stuff pretty rich on boost. Good power for the boost your running.

[Akane]

Above average power imo for a standard MR2, I clocked in at 122rwkw but that was 6 years ago, with their older software. Standard off the yard.

Your car's fine and the AFM's fine. I don't sell dud crap. Unlike a certain person by the name of Looxxie

[mr2--mad]

That dyno is up 18kw since installing your afm bro no black skid mark after start up either I got a great deal off Akane
Im just wondering if my o2 sensor or something else(not the afm i know thats working) is all sweet because its so rich. I figure if I up the boost it wont run so rich ??????,theres a tap next to the turbo I dont know which ways up but I might as well turn it and see what happens

[Dell'Orto]

Its just stock fuelling being very cautious, they all seem to run pretty rich.
Yeah winding up the boost will lean it out, dont go over 12psi without disabling the fuel cut

[mr2--mad]

I havent got a ebc,but there is a tap next to the turbo(so i dont know what i would turn it up to)What about getting the right spring rate spring for the actuator 12psi is that an option?, Theres also an air tube with a screw blocking it under the drivers seat(i guess it used to go to the factory boost gauge) that tees off the boost pressure sensor line which is still connected to the inlet manifold ,should I dissconect that an block it up?
PS i dont want to over 12 but 8 seems pretty lame

[mr2--mad]

Ahh, but if I turn the tap and it makes the turbo boost 20psi(could be any number) and the fuel cut isnt disarmed then I would blow my motor ..again ,Is this right ?High boost no fuel =bang

[Dell'Orto]

Can you get a picture of the tap? Does the factory boost gauge on the dash not work?
If the boost cut is still working, then you wont be able to hit 20psi, it'll cut at 12.5psi.

[mr2--mad]

well it never moved before I broke the speedo needle but after I got that fixed at the speedo shop It actually does go up and down (sometimes) its an electric speedo not cable. I never hooked a air pipe up to back of the speedo cluster unit, positive of that , would the dash boost gauge work off electric wire or vaacum pressure .pic coming

They seem to run rich no matter how much boost you put through (within reason of course) My AFR was pretty much identical to mr2- mads one at nearly 18psi

[mr2--mad]

The tap was in this position for that dyno run

[MR2SIK]

is that little filter coming off the bov? thats probably why its running stupidly rich on such low boost? GEt it plumbed back into the intake, will make a heap of difference.

[mr2--mad]

na thats the rocker cover breather

[MR2SIK]

ah I see.
The bov venting to atmosphere wont be helping the air/fuel ratio, Ask Mr Monkey on here about the difference once he got rid of his aftermarket bov and went back to plumb back.

when I vented my stock one it just belched black smoke constantly, and the flames from the exhaust that you could see from the rear view mirrors showed just how much fuel was being wasted haha

[mr2--mad]

Can I turn the tap with out worrying about blowing up my motor?, due to fuel cut ,I thought about going back to stock BOV (way better)but i decided i like blowing off, it feels so good

[Dell'Orto]

but i decided i like blowing off, it feels so good

In fact...

[mr2--mad]

I guess that is my problem though I should go back to stock BOV it would be alot better cheers Buddy

[MR2SIK]

i got no idea on the cost of it, but that new one from GFB looks good, is adjustable from within the cabin can go from full noise to full plumbback or in between,

[mr2--mad]

What about just gettin my one plumed back to the intake, is that possibly?
