I already worked on torque mgt. In order to NOT change the wrong table can you tell me where the other tables are at? Gen III PCM

I have a 01 burb w/8.1 3/4t and 4l80e. Is there anyway to firm up the shifts using hp tuners? Trans is stock as far as I know. Thanks to all for any input.
So, I watch Goat Rope Garage for pointers on tuning. Back story here is what I thought was a knock or timing issue was actually a fuel pressure issue. Long story short and after urging from tuners...
no headers but duel exhaust. running 93 octane. i'll post tune and log when i can. and yes it may be false knock. i certainly cant hear it. use to work on GM cars in the 80s so heard lots of knock....
run 93 octane and going to log my latest tune. Ill pull my trl also b/c that is what i bought the burb for. scanner shows lots of knock. ill post as soon as i can.
Replacing fuel pump cured all my drivability issues. Apparently, it had been getting worse over time. My next question is my knock sensor appears to retard timing by a factor of 2 to 2.5. Notice I...
Im sorry to waste your and others time. Ill be the first to admit im not the sharpest tool in the shed. Trying to learn HP and also keep in mind there are other engine functions not controlled by the...
i have a fueling problem. idle pressure is 260kPa and drops to 150kPa at 4500rpm 1-2 shift. No difference in pressure when regulator is unplugged. Ill try fuel filter first. should be 400kPa if I...
The original tune was set at 4900rpm and 60s. Looking at all what yall have said and considering the original tune I guess PE was never meant to be used from the factory at all. I mean who wants to...
so, setup PE as suggested. PE doesn't seem to work as engine missfires due to lean mixture. Ill include graph and tune. Look at o2 sensor graphs toward end of log. That is where I noticed it. They go...
ur right. I was actually able to find what I wanted premade in the layout pulldown menu.
got a 2001 8.1 burb. Power enrichment tab shows 4900rpm activation of PE mode and 60s. Does this mean that I have to wait 60s b4 it happens and keep it above 4900rpm? That is the stock tune numbers.
Trying to set up a histogram of advance and retard using rpm on column axis and cylinder airmass on the row axis. All I am getting is top row when logging. Made several adjustments to histogram setup...
is this a one wire alternator?
Files as requested. I might add that temp and humidity were low this morning. Increasing temperature seems to make it worse (IAT). Also, in my youth I had plenty of oportunities to work on non ecm...
i have a 2001 burb that needs tuning in a bad way. it is stock except for a KN filter kit and duel exhaust. pcm pulls gobs of timing on tip in and on hard acceleration (15 to 20deg). boggs baddly on...
How is the ltft reset? I will have more questions soon. Thx for the response
Thanks for the help. My MPVI3 arrived in the mail today. Maybe we can hold each others hand as we dive off into tuning. A few questions:1. I have true duel exhaust. Is it necessary to use two WB...
New here so trying to educate myself on this tuning system. Is there a procedure to tune an 2001 8.1 maf. Watched Goat Rope vid on maf tuning but he goes so fast its hard for me to grasp. And I have...
Im new to this forum so forgive me for asking for something that already maybe posted. I did look though and did not find anything. To my question: I have a 2001 suburban with an 8.1. I'm looking for...
