Can anyone provide input on this?

Thats what casused me to look into the issue. I don't have the Max Pressure enables under trans diag. Coupled with the fact that I have noticed harder shifts when in SD I thought that I was stuck...
That's weird because I can definitely notice the transmission shifting harder when in SD. I will have to log shift pressures vs torque when running normal vs SD.
It is good to hear that they are...
I'm having a strange fueling issue that I can't seem to figure out on my own. whenever I transition from any sort of cruising rpm to idle the AFR swings way rich and then returns back to normal after...
My truck shifts noticeably harder when I fail the MAF. Even with the VE table dialed in and Dynamic airflow reading extremely close to MAF airflow.
Hey guys. So after doing some research and emailing support, it appears that there is is no way to disable the max pressure shifts when you fail the MAF. I looked through the repository and it looks...
If you are going to use the egr to display AFR then you are going to have to define a y=mx+b type equation to relate the voltage input to the egr with actual AFT.
y is AFR
m is the slope of your...
fair enough. I am lucky to have a laptop with a built in serial port. Hooking it up through the egr works well also. Just ensure that you correctly set the voltage offset in your math parameter so...
Im going to piggyback on what 5FDP said above. I have done the egr trick and it works great. On another note, if your have on of the newer innovate, AEM, or PLX wideband then you can log them...
If your are using an innovate LC-2 then don't change a thing from my graphs or channels. That is the same wideband that I am using. Just hook up the special cable that came with your innovate into...
Edit the tables under Spark>Advance>Idle Spark Advance. Also, make sure that these tables match or are very close to your high/low octane tables. The only areas that need to be similiar are your...
Depends on which wideband you have. If you have a serial wideband that is supported by VCM Scanner, then just replace my wideband channels with your channels and the graphs will work. I will attach...
Here is the configuration that I use. I use it for both MAF and SD tuning. Feel free to delete the wideband stuff or any other extra channels that you feel you dont need. I will attach my layout and...
Whenever I have been tuning the MAF I have been setting the High RPM Disable to around 400 RPM in order to rely solely on the MAF. Are you saying to set it to 975 RPM but still make changes to the...
I will work on smoothing out the VE table to try and prevent that from being an issue.
I looked through what James had posted and I am currently trying to emulate his method and get results...
What do you mean? Isn't this what the transient fueling tables are for?
Hey guys. I am having some problems with transient fueling and I would like some advice.
The vehicle I am dealing with is a 2003 silverado LQ4/4L80e. Everything is stock and I am currently running...
My 2003 truck does not have the MAF DTC max shift pressure enabled. Is there any other way to disable the max pressure shifts?
Check posts 2 and 4 above. They have the required channels, graphs, charts, and math parameters. You need to download those and place them into your HPtuners files Documents > HP Tuners > VCM...
Bump for this. I am having the same issue.
Yes that is what I meant to say. I just worded it very poorly. Thank you for all of the help!
Just a quick update in case anyone finds this topic in the future. I disabled the coded 2xLS1 mentioned and everything is working great right now. No more knock retard when in PE and the sensor seem...
Thank you for the advice. I will disable the codes and do the hammer trick to verify that the sensors still properly operate. It will be nice to ditch this timing retard issue.
