Hello I am new to tuning. I have a 2000 camaro with an MTI X1 cam(230/227 112lsa) . A member from here helped me tune it, the problem still exists. I sometimes have troubles starting the car when its warm, and when I get it started it will rev down and die. I have to keep giving it gas for like a minute so that it stays on rev. Also when rolling and when I stop at a STOP sign, it will sometimes die on me. I upgraded to a 2002 tune file. Can I maybe upload the tune so that you guys can take a look at it?
Mods on car are just the cam and free flowing exhaust.
It is tuned by EFI Live

Here is the tune:

Send me a copy of the original OS tune you and your friend did. If it's just a warm start issue, you didn't need to change OS's. I'm not a big fan of doing that unless you have to.

I saw - when I get to my PC at home (where the software is) - I'll let you know. Just looking at the title, any reason why you're running 32* of timing? I know sometimes altitude can affect things. But, did you get on a dyno to see if that's where it makes most power or adjust at the track based on MPH?

we werent seeing any knock at the track so we added little more timing

No more knock is fine and all...but did you gain anything from it? I base my question off the concept of running the least amount of timing that will net you the most amount of power. Adding timing because you don't see any KR is not a justifiable reason for keeping what you added. Running a higher MPH at the track, however, is.

Try this one. You'll need to do a full flash to get this OS back in there. I pulled your timing back down a little until you can get on a dyno or to the track to justify more tming.

I am having other knocking issues before I installed the tune. May be pushrod problem i dont know. I did however try your tune and it is better. When I start it up it will go to about 300 rpm and after 15 secs it works its way to 650rpm and stay there.

Yeah - maybe it is mechanical then. That should be enough airflow. If not, we can add some more to the ECT's where you're having start-up issues.

Yes I think it needs more airflow.. Thanks

Bump up B4343 a little more where it's struggling at startup (based on coolant temps). Try changes of 1~2 grams at a time.

Also, it's a good thing to keep an eye on your IAC counts. If the IAC is struggling to provide enough airflow, you may need to adjust your set screw or enlarge the hole in your TB.
