My bad that was confusing. It was in MDM before I turned dsc off. So was in 4wd with dsc off.

I threw that out there cuz I'm not sure if that makes any difference. Like Not sure if that is any different than if you are in a different drivetrain mode before turning dsc off.

I'll try to get some logs tonight or tomorrow. I only have recent logs of quick 1 or 2 gear pulls.

I'll have to try some dedicated 60-130 and see if it can do better.

youd had to have lifted to get a 8.02, you should be solidly in low 7s

10.53@131mph. Traction issues through 1st 0-60 was 2.79 vs 2.56.
Had logging turned on this time.

Last night the da was good 👍🏾

I don’t think any of us will be touching mcc420, he has the secret sauce magic tune.

Good run man, that is flying for our heavy cars! You must be up around 950-1000hp.

Yours is not a comp is it? Boost is quite a bit lower than mine… timing is good, that looks like the timing I had when I did a similar run, 20degrees in 4th and 15degrees in 5th.

Was that map 1? Have you tried map 2?

Non comp. yeah that was map 1. I haven't messed with Map 2 yet. I'll going try that next then start blending in some e85

I've seen boost as high as 25 but it's usually a little lower.

I have similar boost in 1-3, but your 4-5 gear boost dropped quite a bit. Good times for map1. What year is your car?

Steve your times are just astonishing. When you run 1/4 are you in 4WD OR 4WD Sport? Burnout? Thx.

No burnouts and 4wd.

This is about all it's got on stock downpipes. This will be my last 1/4mi run until I can add downpipes and meth. I'm pushing it for all I can at E40 with this setup and I think I'm done until I can add more mods.

[brad65ford]

nothing wrong with that on E40 and stock DP's.

[AngryInch]

Wish I could hit 135+ I’m capped at 133..

Still a good time, your 60 is not ideal for 1/4 times as you know. You’re over the 100 LC limit? I am not using LC much anymore just to reserve for when necessary lol.

Man that DA is unreal, I’d love to give it a try and see what difference it makes!

[brad65ford]

bro give yourself some credit, what DA are you running in? Your talking 2 mph difference. I'd dream of -400 da lol

[DrivenAgain]

My car is running soft on that run, had some timing drops. Negative DA has a tighter delta as it drops, and then will have diminished returns if you go too low. Here's the same trap but at DA182ft. I'm trying to do less 1/4 runs as it's hard on the car launching. I focus on that 60-130 😀

Looking at my draggy runs, with the same 60ft, every mph at the 1/4 is almost a .10 less et for me… I need the extra mph to hit a low 10 or maybe scratch a 9… but I don’t think it’s possible with JB4, timing is all over the place.

Driven ya 1/4 launches are tough on them. I find 130mph flying on the highway here.. I might switch to 100-200kmh runs as it seems a bit easier to achieve.

[AngryInch]

Driven, I signed up for datazap, very cool for looking at logs. Ive been going back and fourth from log to log, 60-130, 1/4, map 1 and 2.. The ECU is all over the place. Even runs done in the same log, boost, throttle and timing all move around so much, its a crapshoot in terms of results.

Does anyone know where the intake temp sensor is located on these engines??

One thing Ive noticed and in other logs, plus Brad has mentioned, the timing from cylinder to cylinder can be off +/- 5 degrees or more... What is with that, how does it or why vary timing from cylinder to cylinder??

EDIT: @driven Im comparing your datazap log to mine, at the top of 4th gear, ~6800rpm, our boost and timing is pretty similar, however I am traveling at 88mph and yours says 108mph?? How can there be such a difference???

Would be cool to get a tuner to look at our logs to see what is going on regarding the cylinder difference being so large in timing different.

[AngryInch]

Ya would be nice to know what is going on. Can't be spark plugs because yours are new... I would assume there is one knock sensor or maybe 1 for each bank on these engines? I never see knock on the logs..
