converter problem
converter problem I've got a 3200 stall that won't lock up all the time. Put the tech tool on it and the pcm is not telling it to lock up when this happens. I just got ls1 edit but not sure what to change.

Re: converter problem does it unlock whrn say you are just cruising along? Happens out of no where?
Thats the misfire detection. The PCM is recording a certain number if misfires and it senses somethings wrong so it unlocks the converter. You can get EDIT and set those temps to a different value and fix that.
also cause of converter locking issues is ported MAF ends

Re: converter problem It doesn't un lock when cruising. It happens when I leave from a stop it goes thru the shifts and it won't lock up. I read somewhere about the misfire affecting the converter but it didn't make any sense to me. The way you put it makes sense. I've got ls1 edit and I had some help with tqm and shift points but I'm just starting to learn and need all the help I can get. It has a cam and throws a soft code sometimes for misfires.So if I can get that cured it will cure the lock up also? I sure appreciate the help.

Re: converter problem John, its worth a shot. Mine did it right before I got the cam. But after the cam It would unlock about every 4mins or driving. Then after 2-3mins it locked back, then 5mins later it would unlock again. Before the cam it was once in a blue moon. Some days fine, other days it did it 10 or so times within 2 hours.
But your definitly getting misfires and the PCM see's that as a issue and it is more than likely the cause of the verter.
Only other thing i can think of is maybe a bad shift noid or something?? Try posting in the drivetrain section so those gurus can help ya more. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

In it they address your problem. I believe it is on page 40 of the newest version. You can stop the misfire test from running all together by changing the temp, but a better way is to fine tune it so you don't get all the false misfires but will still warn you if there is a real problem.
I set idle, low and med RPM tables to 32000 and it fixed my misfire trouble, and I had it bad with my 3300 high stall converter. I live in the mountains and driving home on the back roads where my car would shift up and down alot, it was not fun to drive, I had to keep it in 3rd to lessen the locking hang ups. It is fixed now, it's like driving a different car now. THANK-YOU Carputing!
