It is kind of hard to answer your question. First off, get rid of that MAF buy a IAT sensor and just work in SD mode. I would say use the repository for a similar tune but you can’t. Second I am...

bump for a possible answer

here is a little of what it does this time it started

what do you think is going on?

cool again thanks

WS6 let me start by saying thanks.
-I have posted up 2 tunes you can look at.
-here is my question w/learned values. I have ltf and stf’s turned off.
-I also went back through my working tune...

but why is the issue ONLY coming up after i write the pcm with a new tune. after it starts never an issue. only when i write something...anything to the pcm.:shrug:

if you look into the help files in the editor under working w/vcm editortuning how to section-user submitted===speed density just follow the instructions.

bump for more insight

ghost i know exactly what you are talking about i had been running same tune for about 3 weeks and i changed the ve a the drag strip and nope would not run. i then loaded the prior tune back in the...

yes the first one is the one if have issues with. here lies the issue. i corrected the idle airflow because of the car would not start when i modified the second tune. that is why there is a...

here is were i started from. but what i am saying i can go out and start the car...no issues, it will crank every time i want it to. but as soon as i adjust the tune (ve table only) up load and try...

After I make a change to the tune and load it up my car will barley start if start at all. The only thing I have changed is my PE table. This issue started out of the blue one day. I changed the...

I removed my maf and put in a 97 IAT sensor and it has been working fine that is the only change before the issues. Now now I have a hard time getting the car started it fires and starts right away...

Yes I was in the process of doing that and played around at the end of my drive and when I got home I was surprised to see the values and this is why I am wondering what is going on with the tables...

take a look at my spark table would this be considered maxed out?

On a factory setting, we are using all the range that the spark table gives us, but in a boosted environment if running up to 14lbs of boost you have doubled the pressure. How does the engine...

I converted to 2 bar in my 02 vette and noticed that the spark table did not also double like the ve table did...why is this? I know the spark table references cylinder air mass and the ve table...

russ thanks for the help so far but let me ask this. why when the maf is pulged in do i get ruff idle and overall bad drive but when unpluged it runs and idles well?

here is a copy of the tune. russ i have done what you said and only the 103 code comes up, if i understand correctly the 102 and 101 should come up also. i can notice a differnce when i unpulg the...

The only way I could get the car to go into SD mode is by unplugging the MAF and my AIT is in the MAF. I don’t understand why the car will not fail the MAF. And second why my spark tables max out. I...

I noticed that i did not have any MAF codes. rechecked and has the 103 to no report i changed and update same. now i get the 103 code but no 102 or 101. I unpluged the MAF sensor and now get the 102...
