Looks like I have this working better. I cut the shift times to .75 of the current values. That worked well so I cut them another .75. The good thing is the hesitation is gone and the shifts are...
I am working on tranny tuning for my 2009 Silvy 5.3 w/6spd auto.After removing most of the Torque Management, I am mostly happy with the way the truck is driving. The only complaint is it seems like...
Removing all of the torque management is fine unless you drive the truck like you stole it while towing. Take it all out and drive safe when loaded. The 4l60e has been around for awhile, even before...
I just got done logging and changing the base running airflow in p/n. It stabalized it a bunch. Now I just have to do the gear and it should be taken care of except for some minor tweaking. I...
Its something about the resolution in the OS....I could be wrong though.
You can show AFR in the timing table format if thats what your asking. Just set the table to be cylinder airmass vs rpm i think it is and plot LTFT or AFR against it. Is that what your asking, or are...
I'd have a hard time tuning a MAF table with that setup.
I always just copy and paste the values until I get the numbers around +2, then i just copy and paste 1/2% to get them dialed in so I dont overshoot.
hey, I will post my tranny file tomorrow. I have an 04 Avalanche that should be pretty close.
Well the shift points are going to be different. You have alot of weight difference, the shifting would be way off. Just start with the torque converter staying unlocked and play with the shift...
If the MAF is tuned right there is no performance gain for SD....
SD uses the VE table so there is more resolution, I havent tuned an N/A setup yet that was more than the MAF couldnt handle, but...
Well I just put the stock table back in there a couple weeks ago. All I had done to it before was up the values to 1.00 where they were leaner. I didnt lean anything else out.
Man finally a question you stumped me with! I got your email, but custom PIDs are not my fav thing in the world! I am logging through the enhanced version so I have never had to deal with this. There...
If its locked, its most likely locked from all reflashing unless its done by a tech 2 or something. I dont know if Hptuners or EFIlive can do that.
maybe, I cleaned it and it didnt help, so it couldnt have been that dirty. I will see if I can log idle airflow and see how far it is off. Only problem I had last time was that the in gear airflow...
What are some things to look at if my truck's idle searches a bit during warmup. When the truck is fully warm this doesnt happen, only during open loop warmups. It goes away right when closed loop...
From what i have heard, the allison has a whole nother controller, it is not controlled by the pcm, at least not much of it is...
The logs really dont do any justice. When he is accelerating the error % is lean, then when he hits some of those cells on the way down it richens up and scews those values. I couldnt get consistant...
Do either one of you have the part # for a 2bar sensor for a v6..the dealership gave me the one for a v8, but its way to big. The 03 v6 sensor is acutally tiny, do they make one for this app? I am...
I have never been done wrong by a wideband o2. I can get my trims to read -1/-2 across the board, which is right where I shoot for. I use it on the MAF and VE table, just make sure you get plenty of...
Man I was just looking at your log, do me a favor, run this tune straight up as it is, then send me a log and I will adjust it a little. Take the log after running it for a day or few. I have seen it...
its coming......wait on it......wait on it.......here you go!!
There is a minimum spark advance table in the Spark Retard section. Try raising that to 2-3* below the lowest value in your main spark tables. Now the lowest spark value will never be below that.
I will post the last tune I did in the morning. Get the main spark tables, AFR adder table, and the PE tables over. Also check the min spark advance table. Those are just a few things I changed to...
