Case relearn??

[1992-25th]

Doing some random browsing today and stumbled accords a thread talking about CASE relearn. I have been messing around with The software for a bit but have never heard of this before. From the sounds of it I need to do one on my current project.

Everything has been changed, new cam, flexplate, converter, ATI balancer, and the stock 2000 Silverado tube has had a write entire done to a 2002 156 so and has a 3 bar SD OS applied.


It is as simple as running through the test according to the help section? Truck does not have any issues and far as misfires and has no code for crank relearn.

Will it work in SD mode?

Setup in the truck if it makes any difference.
5.3, stock crank, forged rods and pistons
241 heads
Triple12 cam (212/212 on a 112 LSA)
Edelbrock proflo intake
Yank 3400 stall
ATI dampener
Like stated swapped to a 2002 156 os with 3 bar SD applied

If you have logged cyl. misfires and you have none or very few then no, it doesn't matter much, imho anyway. Note that the counts build up over time, could take a week of driving around before the DTC triggered... but if you watch the cylinder counts and they are climbing over time, probably it will trigger eventually...

It should be run if any "rotating components" are changed, or the ECU... thats what GM says anyway. Of course you can just edit the tables so that it never happens...

I never tried to see if being in SD mode matters, sorry! Anyone else???

Thanks for the reply, truck is sitting around waiting for me to finish relocating shocks, I will log misfires and see what it's showing
