I just got off the dyno and did about 10 runs and tried my base header 93 file to see where shes at.I didnt pick up any torque but made 30whp on 24 degrees timing up top.
Lovely gains sir and sounds about right. Is this an OE or EC tune?
Mine made 460 on the same configuration as yours. How is the car feeling now? Are those IATs in F on the fourth column, or is that coolant temp?
Currently running 29 on pump, with vastly improved airflow and tempted to dyno this weekend, but I'd rather I did it when I manage a flat 30-31.
car feels good and honestly can't tell the difference until I hit 5500 rpms but other than that feels exactly the same as you can see I didn't pick up any torque over my old file.
it's an off the shelf base header file from oe and runs really smooth.we did about 6 pulls all making within 3hp of each other and really smooth on the dyno without any hiccups in the curve.
that is air intake temp as the shop has the heat on and is in f.the other numbers are the airflow in gs
You may find that on another day, the car might deliver 28 and then there's your ~480whp
Be interesting to see what it now does at the track (well, when the weather improves a little). Last time out you were.... 11.9 @ 119? I could be mistaken, I'm really sleepy.

last time was 121 but on ms109 fuel and race has file.
I was worried to run my race gas file on the dyno but looks like alot ot guys are running 28 degrees on pump gas.
ok, i get it now....so on the basic OE tune you had which was for cars without headers, it was running 20 degrees....this revision of the tune for headers now runs 24.
I wonder what the base C63 file runs if the OE base tune runs 20s (which sounds supremely low in my opinion). My EC V6 used to run 24 too. 25 on a good day randomly for a split second, but never consistently. The base E63 file runs 24-25 also. Just makes me wonder what people are paying for when they choose the base/off-the-shelf variants
Thanks for posting your chart. I always find it interesting to see the almost very consistent 70WTQ drop that nearly every NA M156 has from peak torque to redline. I see it as a good sign most of the time for a 'normal' state of tune. You know you've got problems when your drop is 100WTQ (which I had 12 months ago).

I dont know how you guys are running that much timing without issues.
I loaded up a race gas file last night and drove the car to work this morning. It felt really crisp and definitely felt stronger but after looking at mode 6 data I'm seeing 16 miss fires on cylinder 6,18 on cylinder 3,20 on cylinder 8 etc and I usually see bay 1 or 2 miss fires on my old file and that is usually just from startup.
my car has brand new plugs and coils and new o2 sensors and only seeing 26.5 degrees and my car showed signs of misfires and knoc.
it felt fine but now I can see why some cars ping on more aggressive tunes.
I'll leave this file for what it's made for and use it only on race gas lol

using this setup on android.mode 6 wont work with iPhones

do you know one that will do similar data logging but works with an iPhone. Also how did it pick up misfires and you didn't feel any of them wasn't just one?

I dont but you can buy a cheap android tablet and use that.
here is a picture of my old tune.in mode 6 you can refresh it and look at each cylinder.
as you can see there is only 1 or 2 small miss fires. On the more aggressive file within 15 min it logged over 20 on multiple cylinders.
An interesting thing that I learnt this week via one of the W211 guys - his M156 was posting multiple cylinder misfires on one bank and it turned out to be the VVT solenoid or something. I think the dealer actuated/reset it via SDS and it solved the issue. Keep this in mind in case you keep seeing this code and it doesn't make sense.
