Just got my innovative wideband afr installed and calibrated.
On cold startup I am getting afr of 9.8-10......
I have no cats xpipe porken s4 chips....
Ideas?

The cold start AFR is going to vary by season, but usually shouldn't be less than 12.

Barring some problem with the Temp II sensor (or?) you may need a CO adjuster to adjust for your injectors/MAF combo.
I have not had time to make more CO adjusters as yet - this is usually my slow season but it has been remarkably busy.

Make sure your idle input is present at the LH, #2 idle, #6 ground.


If you want to see the warm AFR (with S4.S300s chips) you can activate 'CO mode' when the engine is warm by turning the key to 'on', depress the accelerator slightly and start the engine. Adaptation will be cleared and the O2 sensor loop will be bypassed until you rev over 2000 rpm or turn off the engine.

Reminds me that i need your co adjuster when its possible Ken,and thank you,Ray

S3s have the CO on the MAF - but I will be making some WOT adjusters for the S3 chips too, which is what I reckon you mean.

Do you have record of who gets adjusters from your orders? I think you mentioned something to me also about an adjustor to me.

I will check what you recommend.

Would love to get the co adjusted whenever you can get them made.

I will take the car out on some runs today and see if it is rich through the entire rpm range....
Last night was just idling in the garage

How long does it stay at 9? On cold starts, my afr will sit at 9 for about 20-40 as the O2 sensors heat up to operating temperature. Then it jumps to 12-13 and gradually proceeds to 14.7 as the engine warms. I think this is normal.

Any likelihood of Blink'r v.2.0? Or run 2.0?

I obtained most of the parts...had a problem with radioshack regarding resistor...then lost some of the parts...

So I think I found the issue.

The innovative gauge needs to be on the brown analog wire on the lc2. But in the white wire on the lc1

I had it in the wrong one. I switched wires and I read about 13 ish...at idle..

Yes sir that is what i mean and thank you
