Transmission tuning?

I can't see that being the case Because your shift points are a constant Maybe you're thinking of the fuel trims dialing In Also try bum in your tcc max /min tables by 10

Edit apply should always be higher than release always.

What do you mean

Yeah i did. I'll reverse those. I almost forgot. I thought I read somewhere to 0 a chart out

Yeah you don't want to do that.

The only table I zero out is the add vs rpm and AFR correction, because I then changed my Base AFR vs ETC to what I want to see at WOT for Air to Fuel ratio of 11.4.
 


Gotcha. I won't change anything engine then. What I have for mods so far is in my sig and I have no wideband yet. Better not mess anything but my trans up for now lol

I've got a few quick 15min drives recorded but I haven't read about much about the histogram display yet to know where to add

Follow the hpt sticky it shows you about how to setup basic histograms like mentioned above you can achieve a ve tune via stfT and same with Maf
 
Yeah i saw that I have been reading it. Just haven't done it yet. I wasn't sure if I needed a wideband to do it.

I'll read up on that one as well. EDIT: i already went through that thread. got some good info off of it, thats the one that explains the histrogram display...its also the one that told me to change iat spark and got the code lol... so ill just have to read into it until ive got it all down.

I have a weird problem going on with Kr.
Wonder if I can upload the tune and scan log maybe someone can tell me why I have such high Kr during tcc lockup? The more throttle the more Kr.. This is with the tcc engaged.. Maybe I have the lockup going to far Into throttle %? or just the obvious to much boost for rpm?

yea i havent got well versed on this one but i did the whole high table 100 low table 50 thing as recommended in alot hp tuner forums etc.... but it feels like the car essentially is bogging down with fuel and KR out the ying yang till it leans back out again, i went back to stock and increased the whole table by 10 and seeing no KR now when shifting and tcc lockup i would recomend your stock settings then add 5 till you get the firmness but no bogging feeling, for me its around 10 at the moment
 
haha thats exactly what I was just doing. I dont even have mine maxed like the thread said, figured it would be too harsh.

Im also putting shift points back to stock, i had the tcc lockup set coming in too early and too far into the throttle%... id rather it just kick out of tcc if its going to cause a ton of KR...from a dead stop though not a bit of KR.
 


Yea my shift points had nothing to with neither did my tcc lockup speed it was the pressure table that ****ed it up
 
You wrecked your trans with the pressure settings? I increased the table by 10% but I didn't increase the max value. I shortened shift times as well.

Yeah i put the shift tables back to stock for now... the tcc locking up until 50% throttle was a bit excessive..

I'm doing the maf tune/calibration tonight after I record a scan following a 30+min drive out to pickup my gxp bumper. Curious see the results
