ECMlink DSMLink logs, whats next? - 2.3L / GT30r / 20psi

[grantman10]

The mod list in my profile is up to date...

I am just looking from some advice from some experienced DSMlink tuners on what to do next...

I do have a wideband, but it is not logging through DSMLink...

I know i have a lot more to do with timing and boost, but I dont know if i should just keep raising the boost until i get knock, or if i should just raise it a little bit and then start messing with timing...

My goals with this car is to run 25psi on pump gas, and flow between 45-50 lbs/min daily. Im the two 3rd gear pulls posted i hit 40-41lbs/min. Is this accurate? or do i have to mess with airflow sliders? Its a stock 2g maf...

I have a log from the previous owner that has the car running a lot better. I noticed that he has way more timing down low and his powerband above 40lbs/min is nice and long. He would hit 40lbs/min at about 5500 rpms, whereas i dont hit it until 6800 rpms. I hoping that this is because i am on 3-4psi lower boost and way less timing...

my car just feels sluggish until it hits full boost and high rpms, please help me fix that... But don't get me wrong, the car would punish my 16g car...

Here is an idle log, a log with 2 third gear pulls @ 20psi, a short cruise, and a log from the previous owner before the engine rebuilt, at 23psi. All of this is 93oct... Note: at the end of my second third gear pull I blew the knockoff hks bov right off the uicp so if anything looks weird after that, that is why.

Timing is stock, and i have not touched fuel sliders. How are my fuel trims?


Thank you!

Edit: I should have noted that there is about 900-1000 miles on this motor, and I am just about to do the second oil change after my external oil cooler gets here... Is it too soon to be beating on it?

What AFR are you tuning too at WOT? I would add some timing down low, maybe dropping too 10-12* at most. That will give you some power back down low. Peak timing looks good.

I haven't started messing with the fuel sliders. I am going to be aiming for an 11-1 a/f ratio...

How should the timing look? Should i have pretty high timing, and then as the car starts to boost lower the timing back down. And then slowly build back up to about 16-17 degrees?

Thats what the previous owner did and his logs look good? Should i just move all the 1k 2k and 3k timing sliders all the way up or no?

Im kind of lost on what to do with timing, and wether i should worry about target boost or timing first.

Im thinking that i should get to my desired boost level first, then get my a/f inline, then worry about timing. Does this sound right?

Are my fuel trims good? Because i never had to touch them if they are...

I'm no tuner, but I looked at my logs from my AEM EMS and it looks like that's what they did. they started out high on timing, then back it down some as boost builds, then build it back up.

That 17* peek timing is probably as high as you are going to get it with 20psi.

Add some timing down low to give it more pickup.

Start out tuning that 20psi setup. Give it timing pre-spool and then lean it out. Get that comfortable then add some fuel and pull a few degrees of timing, add that last 5 pounds and start all over again. Doing a semi 20PSI tune first will make it easier to get that 25PSI down faster.
