    EEhack

    Hello everyone a little new to the tuneing world. I tried using EEhack for the first time my 94 T/A LT1 be for that I used tuner cat. The problem I have I tweaked my injector pulse width alittle because of a cam swap so I loged the car made my change and re uploaded to the ECU now my LTrim left and right are locked at 128 am I missing something. Thanks for any information Gary

    you definitely changed something else.

    what emissions controls did you disable?

    what xdf are you using?

    there are various conditions that must be met for blm and cl to enable.

    are either of the cl or blm indicators coming on in eehack? post your bin and/or log and ill have a look...

    also welcome aboard

    log file

    Hey Steve I love the program you made 100 times better that the one I use to start with. It is very possible I did do something or not did something right. I use Tunepro to log as you suggested. I will send you my log. If you don't mind looking at it that would be great. ill attach the bin if I can figure it out. Thanks Gary

    No CL or BLM are not coming on all I changed was the injector plus width. But as with all new toys I was checking everything out and it is very possible I did do something. so I loaded the last tune back in with tunercat and still no Blm readings they were stuck at 128. I thought by putting the old tune bask in would fix it but it did not. Thanks Steveo

    lets see a log?

    it should go into closed loop if:
    - the closed loop min. time has passed
    - the o2s are 'ready'
    - the coolant temperature threshold has passed

    is it possible it's not getting hot enough?

    this could be a coincidence unrelated to you changing bins...

    you can upload a .zip file i think just try zipping it.

    zipping the log and the bin you were running at the time would be good practice for getting help on a forum like this...

    seems a lot has been changed in that bin but i don't see anything specifically that should prevent closed loop.

    take a datalog with eehack and post that

    your o2 sensors are not doing well. they are both parked at 450mv from cold start.

    open the graph window and select 'left oxygen sensor volts' and 'right oxygen sensor volts'.

    a healthy o2 will start at high voltage (900+mv) and as the exhaust temperature rises, start to dip a bit. then the car goes into closed loop.

    your o2s are never 'becoming ready'.

    see attached graph

    Wow didn't pay no attention to that they look like they are dead. I will have to check wiring. Maybe dead o2. That could be the reason it won't go in to close loop and are stuck at 128 BLMs ? Thanks Steveo I'll go take look and see what I find I'll let you know
