ECMlink New SD user, 3rd gear pull.

[DSMer541]

hey so yesterday was my first day on Speed density, I dont have an IAT yet though so this is all just on a map sensor, and I know it says im still on a 2g maf but It is on SD, I changed it after I already started a log. .... attached is a 3rd gear pull to 7k, everything looks pretty good and lines up well but starts going rich anbout 6.5k.... let me know if you wanna see a cruise and or idle log, I have those too.... but im new to this SD thing so any input or help on where to make adjustment would be great. thanks.

Can you go ahead and post a proper log that has your current settings? A lot of times looking through these things isn't just looking at your pull. It's also going through settings and looking over your settings.

As far as it going a little rich, you can always tweak your VE table with one of the tools created by an ECMLink user: ECMTuning User Support Forums

I have ran a few logs through that, made the changes to my VE table, and had some wonderful results. Take that for a spin, do another third gear pull, and post it up.

found out why my AFR is dropping rick after 6K.... my punishment intercooler isnt effincient enough at that boost level so intake temps are rising higher than they should, heat soaking the intercooler and causing a rich mixture, thus haveing to lower VE a ton after 6K....

just got an ETS pro race intercooler and a GM intake temp sensor yesterday, so I will post another log tomarrow.

Sounds like you're on the right track. Getting a GM IAT sensor installed in there will help you quite a bit. I had my battery go out on me and my tune went a little weird and didn't have the GM IAT pin assignment, once I figured out this had happened, I noticed a nice difference driving around

here is another log.... I still dont have an IAT in yet, I have it, just gotta have someone weld it in, hopefully this friday... but this new log is with a new ETS 3.5" intercooler.. I was able to get afr lined up a little better up top, and gained a little extra power... feels good.
