Dont the 99 and 2000 model trucks show a lot of false KR? I dont know if you are running a 02 pcm or not but I remember this being discussed a lot a while back..

 

i remember it being mentioned. it sucks because i have the tuning software for 00 and 05

 

I know bigtex had big trouble with his truck.. might want to check with him..

 

holy crap.

im watching my log... and ive noticed the KR spikes as i watch my tach go up. and it looks like i get a spike evrytime the tranny shifts. and the big spike is when the TC would be locking.

well now that i threw that code my TC doesnt lock anymore and im not getting the same spike anymore.

 

I had the same problem with the shift silenoids after replacing them both twice I got my software and realized it was because of the positive force motor current, I would set that table to stock if it isnt.

the kr with the tc locked is something we all suffer from once you get it down to no kr anywhere but when the tc locks the computer will learn it out if its 1-3
only worry about the lt's when under throttle not the ones you get when you let off from wot

 

what should i do about the TC not locking now?... what the heck is that about?

i have an LTFT tune ahead of me.

 

lock the tc manually with hp (its under vcm tools click the button while driving) if it locks fine then the only thing that causes it to not lock is misfires and I dont see a cam in your sig so that shouldnt be the case.
Excessive kr might cause it not sure I would put the stock timing tables back in and tune your fuel first

 

it just started doing this about 2 days ago. it was locking fine before. it would start dropping RPM at about 40 mph.

 

Did you do your trans-go install at all? You might have of screwed up the TC valve part.

Would it ease his LTrim tuning at all if he were to unplug the knock sensors all together? That way he'll get no KR and get the fueling under control.

Also I wouldn't load a stock timing table with your setup. Not with our ****-water gas and this heat we have. You might see even more knock.

 

BIG NO NO never disable the knock sensors I dont even like to desensitize them as much as alot of professionals do, but with the 99' sesors that was a bad year so the very last thing I would do is tune the sensitivity tables under global kr.

The stock tables are gonna have less timing in them than the tables he is using now they have 11 for wot, gas doesnt matter here. I dont think anything is wrong with his shift kit install it would have come up a long time ago.

Onyx: Have you edited any tables? Did you command the converter to lock with hpt-did it?
