Here is my log file and tune. My vacuum is pretty low, I've heard you should try shooting for the highest vacuum possible. How would I go about doing this?

Here is my log file and tune. My vacuum is pretty low, I've heard you should try shooting for the highest vacuum possible. How would I go about doing this?

Thanks, made some adjustments, I'm gonna start off with a high airflow final min. and work my way down.

edit: uploaded the tune, it was much better than before, thank you so much, idle was...
Thanks, I saw in my log file that under dynamic airflow it was showing about 200 maybe around 1000 rpm and 180 around 800. Would these numbers be suitable to put in the min. airflow table, or does it...
Hello, I just did a cam swap on my 05 Gto and I can't for the life of me get the idle sorted out. Mods include e85, procharger, longtube headers, magnaflow exhaust, and a ccp jam cam which was the...
I think you misunderstand, I already have a sd tune that's pretty well dialed in, it's proven to be reliable thus far. But now I'm installing a bigger cam and I want to know how to account for a...
Hello, I have a 05 gto, ls2, d1sc procharger, 4.00 pulley, longtubes, exhaust, e85, etc. Speed density tune.
I'm currently installing a cam, previous cam was stock. I'm installing the ccp jam cam,...
Hello, not sure if I am in the right section for this but I don't see anything else. A family member got a p0420 code with their 2013 ford focus se flex fuel. The shops were trying to charge roughly...
So first off my build is a 2005 gto, e40 pcm, stock ls2 with stainless works long tube headers, full 3 inch magnaflow catback exhaust, D1sc procharger 4.00 pulley about 10psi, flex fuel sensor.
I...

There we go, looks like it made a little over 9 pounds, I feel like it should be making slightly more but that's pretty close. It's slightly rich, I'll make adjustments. Should be pretty...
Yes I do, I did some wot pulls afterwards with boost, but I was making less than 7 pounds of boost. I'm getting belt slip for some reason. I've always had issues with my Procharger tensioner and...
Did a couple of WOT pulls with no boost and got some good data.
Should hopefully help with the boost VE table now.
I noticed over 6,000rpm the car felt like it fell on its face, I'm guessing...
Thanks, the knock settings helped, no longer detecting knock which was probably false knock.
My high rpm VE cells are definitely off. I tried going high rpm low throttle and it was about 10% too...
Here is my most recent log, starting to make some progress on the VE tables. I reduced the spark advance even more by copy and pasting the stock IAT spark advance correction table. For idle, I copied...
Thanks for the tip on smoothing.
I tried to add 2 to the entire airflow final minimum and had no luck, I even tried 4 and didn't notice a difference.
Whenever I disabled clutch fuel cutoff in my...
Okay, I took the set spark tables done by my tuner, scaled the spark location by 50%, so spark at .08 shows up at .16 and so on. Then I put the differences between that and my high octane...
I was looking through my tune and to my surprise it seems I still have Clutch fuel cutoff active:doh: Hopefully tuning will be easier now with that deactivated.
Also, I don't know if this is related...
Thanks, not sure if I will end up wiring a switch or not but it may be a fun experiment.
I haven't made much progress on my ve tables yet. I have a manual so I wonder if that is affecting the...
In the end, I think I want to run SD 100% of the time, but I want to be able to switch to maf easily in case my map sensor fails, or something else happens.
What if I set up maf to work in the tune...
Okay, I tried to hit boost and kept my eye on my a/f gauge to make sure I don't go too lean. I was aiming for the early cells in the boost able to start off with. Came home and to my surprise I never...
Okay, went for my last ride for today, I've been getting slight knock here and there but I'm not sure if it's actually knock. I put my spark tables back to the way they were before during the...
Okay, so I updated my ve tables and estimated my boost ve tables for the time being(probably way off). I just read somewhere that when in SD mode, the ECU will automatically use the low octane spark...
Okay, so I uploaded the tune and started the car, at first the EQ err was off about 1% while the car was warming up, once warmed up, it was 5% too rich. Went for a quick drive around my neighborhood...
Thanks, I already put my highest values from the boost table in their so I'll give it a 5% increase.

I reduced my flex spark since you said if anything reduce spark advance for now while I...
Thanks, I just reduced the spark while I tune the VE like you said. I just need to multiply by 2.5 to get it back to where it was. Hopefully I'll get a chance to start tuning tomorrow, a little bit...

Here's my current file, I multiplied the flex spark by .4 to reduce it for now.
