The stage 1 I got off this website. The stage 2 is a JET one I bought awhile back, I can upload them all if anyone wants to analyze them. After a min or so in the log where I set for a min before I took off it had a good idle. If I could change something for now to keep an idle like that I'd be pretty happy cause I got pretty good power with the stage 1 and 2. I can data log the stage 2 later and upload that also if anyone wants to see the difference.
The Stage 1 on the site is a Hypertech, not much change from stock, when you have time compare it. You'd be pissed if you spent money on it.
I'd like to see the Jet Stage 2 as I never saw one, from what I read it would be best choice for you....
BTW neither of those companies are the one I was referring to as not reputable.
Clear BLM learn after you put it in. If I can see the file and a log I can point you in right direction. You still have a long learning curve ahead to get this right. By then you'll be like the rest of us and always tweaking something...

The reason you started to idle better at that point was you went Closed Loop and fueling correction started, but it soon bottomed out.

Yea i wasnt all that happy when i figured out i paid that much for a stage 2 being not that much better. What company would be reputable? If you dont care ill upload the stage 2 to the bins page also. Yea i like tweaking as im either working on cars or building computers so i figured efi tuning would be a combination of both.
Ill get a log for the stage 2 tomorrow after work and upload it. When you said my BLM and INT is all over the place, you think my stock o2 sensor would be right also? By the way on the highway anything it changes is not noticeable. There was also alot of hills so i can data log on a flat road which ever be easier. I dont know if i meantioned the headers are mid sized and 3" pipe, dual all the way back with dual flows.
Well I take that back, there's nothing in that Jet chip that would help over a stock chip for your engine. It's almost a stock chip, few degrees timing at WOT is about the only thing noticeable, all other changes are because I don't know what exact chip they were replacing to compare it to.
That's what happened to me!Yea i like tweaking as im either working on cars or building computers so i figured efi tuning would be a combination of both.
No it doesn't, maybe the average? Min and max are far apart. Idle is pegged at bottom taking out fuel.I meant my blm stays close to 128 when driving in closed loop.
Well Jet just made it to not reputable?What company would be reputable?
I thought you wanted to learn to tune? If you want to buy a chip PM me. I'll still help you learn one way or another. It does not happen overnight, I have years into this and still learn everyday. Every built motor is a little different, for that matter stock motors are or GM would not have a bazillion different chips.
Just trying to help you get going... you can log, you can read chips so you can burn chips. Have you done anything to a chip yet? Did you read this thread?

Yea I'm still wanting to learn. That's what I thought when I comoared the difference from jet and stock tunining, I knew then I needed to be custom.
I've tried a few things on my own like dropping the whole spark advance table to compensate for the less vacuum from the bigger cam. The idle is better when I drop the timming down at a idle but if the rest of the table is still high and after its reved alittle the idle dont fall back down. If I knew where the graph would be good at mabe I can change fuel tables.
I think what would help me also is knowing what all the stuff means in the definition and what it does that I can change in the bin. And what to start looking for when starting a tune
I know its something I can be good at as I done some other things I thought would be hard and wasn't like rooting a phone and opening apps, building a public game server.

How you determine that it needs to take more fuel out? My BLM and INT is at 108 so i thought i would have to add fuel to get that back up to 128.End of your log has some idle time and BLM is 108, which is minimum, so it's taking out fuel and still needs more out.
Im reading up on the link you sent earlier also.
