Hey guys I am having problems with Crome Closed Loop. Tuned with Crome Pro 1.6.19. Using brand new AEM Uego.

First 5 columns are tuned for ~ 14.7 afr. When running open loop, the gauge holds steady.

When I turn on Closed Loop, using AEM Uego Narrowband or OEM Narrowband O2 sensor, the gauge is very erratic. Holding steady throttle the afr jumps everywhere, 11, 12, 14, 15, 18, 11, 12, 14, etc. No CEL.
I have also included my crome tune below. Let me know what you guys think. Thanks.

Specs:
JDM b18c GSR
Nippon USDM ITR Pistons 82mm
GSR Rods
ITR Cams
Hytech Replica Header
3" Exhaust
3" CAI w/Veloctiy Stack
OEM 240cc injectors

can you post the bin directly here? I don't like downloading things from dropboxes

 

Sorry I forgot you can add attachments in HT.

 

If its worth anything to you, I could never get crome to run well in closed loop. Ran beautifully in open loop though.
