XEDE to MS - I'm still mixed about how it runs now
My car was great now it's good.
With the MS I love the idle and low kPa driveability. I can go slow in traffic much smoother now. What I miss though is the slam dunk power. It feels like I have traction control as it builds power slowly and never really pushes me back like before. It's the opposite of a light flywheel effect.
Take that lightly as I still have a lot to learn about MS. Also I'm no longer able to control VVT so that accounts for about 20+ HP/TQ midrange.
I hate pestering Reverant as his time zone doesn't mix well with mine. He's been great with after sales support but I should let him rest a while.
We have recalibrated TPS and the wideband.
I've been autotuning all week with runs to and from work accelerating hard when possible. Trying to get the cells in the boost range all set.
Here is a log showing full throttle run and holding it at 100 TP (not trying to blow the motor and get a good log. It was blizzarding outside here in Canada so it was a bit dangerous as the rear end got loose) and my .msq
My AFR's under boost show tad rich on my Uego gauge while glancing over during runs but the VE tables seem lean??
Could it be base timing, exhaust leak, fuel pump, some other mechanical issue?
I'm going to check the base timing to see if something moved.
Let me know if I've totally messed something up and how we can bring back that lovin feelin......

I love when turbo cars with crappy tunes get on the dyno or track and make me lol.

wonk dit dit
From the movie A Simple Plan.
It means I am at a grade 3 level understanding of what's happpening to my car. Sure I can mechanically rebuild my carburated dirt bikes top and bottom end an tune by jetting. My nitro R/C car runs nice but I am still a noob with MS. My XEDE had fuel and ignition and that's all to adjust and so my brain worked. Once I get above 2 parameters its like I can't taste all the flavors !!

Oh that's not my Ve table, its one of those pictures you look at and after a while an image appears. The image is my facepalm.......
This is after VE Live.
Do I just keep on autotuning? I used a base map and then got correcting with Ve live every time I went out in the car. I have EGO off and Accell at 100% TPS.

Will do.
I assume I'll want to make that hour or more full of boost runs all through the rpm range and avoid steady state cruising all the while hitting burn every so often?
I'll report back after I get some more autotuning done over the next while.
Thanks

Why would you want to avoid steady state cruise? I'd think if you want it to run right during a steady state cruise (with light load) you'd want to get that scenario dialed in just like everything else. Otherwise you just aren't getting any time on that part of the table.
Use the upper-right corner map in tuner studio to tell what sections you've hit in a given run and what sections you haven't. You want to make as much of the table as green as possible.
EDIT: Have you scaled that table for larger injectors? It looks like you're pulling massive amounts of fuel in some areas, but haven't exercised others at all. Was your base map set up for stock injectors?

My steady state is good while cruising lightly to work on the highway.
The map was from Reverant, and we are both wondering about it pulling fuel. I can say that the dash AFR at boost looks good so I'm not sure.
I'll keep tuning daily to and from work and lunch times.
I'm ordering the vvt this week and get that all squared away.
What about EGO and accell enrich, leave as is?

Hey Reverant can you send me something like this that applies to my specific car and the MS2 build. Just so I can double check all my settings one more time.

Thermistor: (Note: These settings suck. They work well around 160F, so I use them. Be aware, at high temps, it maxes out and has a hard time being accurate at 200* if you try to correct the resistance for 99* instead of doing what I did. This needs work! Make sure fans work after setting this.)

THESE ARE ALL BASELINE! NO PROMISES THEY ARE RIGHT! CHECK THEM ALL< READ UP ON MS-II AND HOW IT WORKS. Bad settings here CAN AND WILL blow up your motor, over heat it, etc.
This thread is to work out good settings, but, everyone share their ideas but nothing here is to be considered a recommendation or an endorsement, including (and especially including) ME!. :-)
That said, this shouldn't be that bad. The only real way to get in trouble is to not understand what you are doing. Don't set these settings and try to run the Indy 500. Load them on and CAREFULLY check everything. Go for a drive and log what you saw, IF it starts.
