How are your cars idling with the Mototron 60's?

I have same exact results...car runs great but idles at same idle with the wideband

RICE ETR- what are your fuel trims and inj PW at idle?

if you have a stock regulator use this flowrate
7.87 7.89 7.91 7.94 7.96 7.98 8.00 8.02 8.04 8.06 8.09 8.11 8.13 8.15 8.17 8.19 8.21
adjust the whole scale in percentages up or down to get -1 or so l trims for your specific combination, but the above is stock cid.
7.87 flat across for a referenced regulator with 60psi 0 vaccum.. adjust same as above if necessary.

Thanks Mighty, I've heard good things about these on cars w/regulators setup by the rail, this is how mine is, fuel pressure at idle is 63psi

just wanted to bring this back up.....
As mentioned i have a 1:1 reg, fp set at 60psi with no vacuum and 7.87 IFR all the way across. At idle my AFR is 14.5-14.8 sometimes i see a 15.1 or so.... and crusing in any gear is the same. L-trims are slightly negative also. This is using an innovative WB by the way.

still having problems here, ltrims are avg -10 no matter what i do...
and in drive(A4) at a stop(idle under load) the PW is around 1.86 no matter what. I could tune idle in PE but that wont fix my part throttle...
Might have to get smaller injectors..
With my stock cam, would it be bad to bump up the idle air?
Dont know what to do...

ssnakekiller, if you are going to use that CAS regulator, dropping the pressure will certainly help.. you can drop it way down if necessary
secondly, stock automatics idle lower than manual cars and that could be part of it as well.
also remmeber that -10 L trims are not doing anything as far as hurting mileage or performance

Well, at around -10LT my AFR is in the 10s & 11s so I beg to differ. This could cause washing and could faul out the plugs...**** i'd be happy with 13:1 afr, but this 10-11 bs has got to go...its gotta be the pulsewidth lower boudary like quicksilver said, but i am not sure. Fuel pressure will be next test...then if that is a no go i might just get smaller injectors...
when i am in drive and at a dead stop, and then go to accelerate, the car bogs first(i am thinking because its running rich) and then after a 1 second bog, it seems to be ok...

I think you have something else wrong. Your car thinks you are at stoich when it is at -10% when you are in closed loop (you verified closed loop, right). If it thought you were still rich at -10%, it would still be pulling fuel all the way to -25% where it would top out.
I am not sure what to tell you, so hopefully someone will chime in. Was your car OK with your old injectors?

it ran great with stock injectors...
well i ordered a new 02 sensor and cable bc i think there is something wrong with this one(for the wideband)...maybe it will read correctly, but it seemed to be working with the innovate wideband because when i would put the car under part throttle load, it would level out to ~ +-14.7 and when i would scale the PE table up @ wot it would show richer AFR every time. We will see.
But why does the engine sputter from a start? Also i notice a lot of carbon buildup, seems more than normal...
Next things to try will be new 02 sensor, regulator, and check the plugs to see what kinda shape they are in...I will report results.

I might just go ahead and get some 42's and hopefully be done with this bs. I went to another wideband today and my AFR at idle was 11:1 with -10 LTRIMS and i am sure my plugs are black but i havent checked yet. Yes car is going into closed loop and still running like *****...
What 42 injectors are most guys having good luck with? svo? or what?
Thanks

much better than the SVO junk. My car ran great with them, but I was starting to max them out in the 600RWHP range and went with the 60s.
