ECMlink First Start Log on SD on E85

[mattp_65]

Hello All,

I finally broke in my motor with about 1500 miles. So I decided to switch over to SD and now I am running super rich at idle. How can I fix this? Also please double check all my settings as I followed the How to tune 1G Speed density no MAF.
Also I am runnning on E85 only.
Please help me out.
Thanks in advance.

Your car is in open loop the whole log. Any idea why?

Will I fixed one thing. I forgot to add a hose to my map sensor to my vacuum nipple on my intake manifold. So my AFR is normal but now I have high airflowperrev any ideas?

Step 7 in the "How to Tune SD with no MAF" article your following:

Hit the track datalog button and it will show what cell the ECU is using at idle. Now if the airflow/rev is real low that means you got a boost leak but if it is around that .25 (+/-.05) you just need to adjust that cell the ECU is using to get Airflow/rev to that .25 number. So go ahead and hit the track datalog button again to make it stop tracking so you can make an adjustment. If your Airflow/revs are too high subtract numbers from the highlighted cell in 2 point increments and if they are low add 2 points, and of course hit save to ecu after you have made a change.

But like Brian mentioned, it doesn't seem like the ECU is going into closed-loop, which is an issue for idle tuning.

Just curious - did you read and do/check everything in this list?

^^ Yes I have read this many times. Sometimes I get all caught up and forget the basics.
Ok I figured out why my AFR was high and all out of place. I forgot to add a hose from my MAP to my intake manifold.
So now I adjusted everything and here is the latest log of Idle.
I think I am ready for a cruise tune.
