ECMlink 1G Can't get into closed loop

[blizz99]

My car won't go into closed loop and it's idling and running horribly. On DSMLink the o2 isn't oscillating like it's supposed to so I replaced it with a new one and still didn't do anything. Also, when I step on the gas there's a pretty good hesitation. Anybody got any ideas on what else I should do or what it could be?

Straight off of ECMLink's site:

1G Learn mode (all must be true):

Coolant temp >= 190F
Intake air temp < 123F
Baro >= 22.9 inHg
Baro <= 31.6 inHg

Log those sensors and find the one that isn't true. My guess is the CTS.

Posting a log would help if you can't figure it out as well... .

i am having the same problems.. what are the sensors i need to check out that need to be right for the car to go into closed loop.

i know the o2 has to be right. and the ecus coolant temp sensor.. what else?

on my logs i am only getting 15 degrees advance during a pull and it never goes into closed loop.

Check TPS and ISC also.

Since this post I've switched to working ISC and TPS sensors and also switched to DSMLink v3 SD and now I don't have that problem anymore.
