Head was heavily ported by Tyler Van Lant; there exists flow curves before and after, but I'd have to dig them up ...

Makes sense.
Thanks again!

Thanks for your help.
The shifter feels good through all gears; it's got new poly bushings, and the fork pads were on when I put it back together.
Does it make any difference that it goes into 5th...

Hello!

I have a rebuilt (approx 20k miles ago) A523 with an OBX LSD.

Everything has been great on it until recently I noticed a small drip coming from the aluminum plate that is sandwiched...

Thanks for the info Rob.

Let me chew on this for a few days and see if I can both further understand it and come up with a simpler explanation to help out.

Can anyone explain how to tune the O2 kicks to get leaner adaptives?

Goal is a leaner cruise and a leaner AFR during idle. Currently at about 14:1, would like 14.7 at idle and during cruise (or...

Using tryingbe's curve, when I start up now (cold), I idle at about 10:1 for ~60 seconds before it leans out.
With the curve I had originally (B246), I would idle at about 9-10:1 for ~10 seconds...

I uploaded a JPG comparing the 2.5L B246 cal, 2.2L A171 cal, and modified A171 cal tryingbe is using.

To summarize:

I will try what tryinbe has done. I...

Thanks for the info, but I'm even more confused now.

You are using 83 lb/hr injectors on your setup, right? And it's a 2.5L?

If you made a 2.2L cal w/ 83 lb/hr injectors - and it was too rich -...

I'm confused; could you clarify why you scaled the 2.2L cal to 56 lb/hr injectors?
Also, what 2.2L calibration did you use? I'm going to try this on my 2.5L 3-bar cal.
Thanks for your help!

My AFR's are almost exactly like this too.
Starts off at 10-10.5, then 30 seconds or so after start-up it reaches 14.7.

Any other ideas as to why a 2.2 cal would be so much leaner compared to...

Thanks for the reply.
I also neglected to mention in my posts that I am using a factory narrow band O2 sensor in addition to the LC1 wideband O2 (which just goes to a pod gauge).

Good idea...

Thanks Rob

So today I keyed on and let the LC1 pre-warm as suggested until it read full lean (22:1 AFR), then I started it up. AFRs still read about 10-10.5:1 until about 20 seconds after being started, then it...

The template I am using is modified from one you sent me.

Bounces around.
I'll try pre-warming the sensor today.

Rob, or anybody that can help:

On the Turbonator SBEC calibration, there are several options to select which input is used to determine the HI/LO boost.

Rob,

Did you ever get any help on the staging limiter issue? I can help.

I can help too.
Let me know.

I'm using an SBEC

Unfortunately my calibration is scaled for the SBEC version you have (above, red), and it is experiencing the same issue.

It is based on the Turbonator T-SBEC B246 calibration.

How about the table TimeO2InhibitedSwitchingRichIdleToClosedLoop?
Is this value in seconds? Mine is set to 255.

It seems like it's really rich immediately after startup until about 4 minutes;...

Thanks a lot for the link!!!
