I"m having a some trouble with my tune that I'm running. I've raised my shift points in the tcm up a little bit as suggested but now its shifting pretty rough. It is most likely because i am using the stock engine torque tables. Im just wondering if anyone can help me make a good one that compliments the new shift points. I still want to keep some defueling in the tune since i have a stock trans still
Thanks

Danny this guy needs your help

 

what rpms did you raise the shift points to, are your b0741 and b1102 tables modified from stock already?

have you done a log measuring the parameter GM.DMax_Trq_dma to see whats goin on

 

if you look at b1102 you can see the desired torque limits drop alot past the stock shift points which were 3250 rpms. thats whats causing the crazy defuel in one part. then you have to raise your b0741 table to match that.

 

The way its set up right now the shifts are around 3400-3500. The tables right now are stock. I have not logged that pid yet.

 

well how did it shift before you raised the shift points

 

btw, i never had to touch the trans to get the tunes to runs smooth. I do mess with the trans but thats only for 2nd gear launches

 

It shifted fine before i raised them, it was just kinda suggested to raised them to get the shifting out of real high torque areas. I didn't raise them to smooth out the shifting, just a little experimentation.

 

yeah that helps out with the trans, but power wise you get out of the rpms of what the stock turbo can make good power at.

did you already raise the torque and fuel values in the the new cells that are being used or not done that yet.

 

I haven't messed with them yet i was kinda waiting for some advise before i messed with them much, so far I'm going to change in B0741 make the values in 3300-3600 the same as 2800-3200 getting rid of the jump to 106mm3 which should take care of the jump as its trying to shift and right after. In B01102 and raise and level the mm3s from 2800rpm on to get rid of the big drop of that seems to be happening around 2600 2800.
