Tuning Impressions, Opinions and a few Questions

I wouldn't worry about that, there is enough memory for some excess before and after.

I start a little early cause I've been having some lag

I wouldn't really log tip unless u are doing some advanced diagnostics...that is the map sensor pre throttle body...it will confuse u a bit...u want manifold pressure

So I had selected PSI like so and it still doesn't display properly on the device.

Also, here's a janky log for anyone who cares to look.

Interesting that HPFP fuel pressure stays up above 2000 psi even when the throttle drops back halfway. Don't know if that if that means anything, but on logs from other SHOs, that is not the case.

It was WOT the whole time, it just shifted on me. Also, can you add a PID to a config?

Pm me ur email and I'll send you the config I use

Yea u can..it will ask u if u want to merge the items when u go to the menu to add more pid

Well i figured it out. Here are the steps. 1: Load your config file from Torrie 2: Click guide me 3: Create a config file 4: Select communication CAN KPW2000 (this is key) make sure "load complete list" is selected below as well 5: Click select items 6: Scroll down to turbo and select turbo boost 7: Select configure datalog, name it and save it. 8: Select Export DLF/DLX, select X4, name it and export. 9: Open SCT updater and select the DLX config file and there you have it.

All that just to get boost in PSI to show up with your custom config file. SMH

Yeah, that's not QUITE simple! Glad you got it figured out

The car throttling itself is just something it will do at times to control boost....Torque tables most likely need work. In the tune the commanded torque and airflow must match. If they don't the throttle will fluctuate....It gets complicated

The log looked ok. Knock activity was good. I suspect that was a preliminary log. The throttle will open eventually but if it fluctuates don't worry about it. I suspect you also will be getting more boost as torrie dials the car in.

You don't have to stop the log as soon as you are done pulling....Let it go until it's easy for you to stop it...It's easy to find the section of WOT and zoom in on it. You can start it sooner also...Go ahead and let it pull 1st through whatever...The more data the better...You didn't really start until 4k in 3rd and barely got into 4th.

Well, I lied. I go to load the file on the device and it crashed it. Apparently it cant pull PID's from the different communications. My next step would be to do a whole new file from that other communication. Dang it

That's why I said janky log, i was in traffic, yea i'm that guy. When I was tuning I really only wanted a solid WOT in 4th from ~3-6k. It made it easier to see with out the shifting of gears and such. I'm sure Torrie sees it all. As far as boost goes, there are some spots where im over 90% WGD, those little turbos are about maxed there for sure.

I wanted a boost in PSI on the SCT as well, and also am having issues with it. Torrie told me to just create another config and all would be well. I tried multiple times to create a config that has all the things Torrie wants to see and the Boost in PSI that is in the misc section at the bottom. The config opens and shows Boost in PSI, however when I load the config the the X4, Boost in PSI is nowhere to be found even when logged and opened via Livelink.

Your wastegate duty was actually very low during ur wot....40-50 or so...for some reason the wastegates are held shut during cruise and coast....u were nowhere near maxing out those turbos...your boost was relatively low during ur pull...

U said u only wanted the pull from 3k to 6 k?...why?..the more data the Bette the tune

Hmm, I see what you mean now. Why in some spots do they look over worked, 90%+, then in others even with more boost look like they're on cruise control 60+%?

A good clean pull from say ~2500-6k in 4th would tell me everything i needed to know. All the extra is unnecessary clutter to me.
