Talking Hitting the Strip Next Weekend- new to logging so review/input is appreciated! - 09-30-2017, 01:39 PM

Hey guys,

Finally done with my first round of modifications, but am still trying to learn about what to look for on the logging end. I have some buddies that want to hit a test and tune next weekend so I thought it may be good to have my logs reviewed prior to going.

Car is auto with 85K, and some pretty beat stock turbos (riding out the smoke/WG rattle until a single turbo swap over the winter months). All the usual mods- inlets, outlets, *********, FMIC, charge pipe, intake, relatively new vacuum lines with aftermarket canisters, JB4 G5 running map 5 with 4 gallons of e85 tossed in. Car runs smoothly and hasn't been throwing any codes and there are no misses or hesitations. The only thing I notice is that I feel like months back my boost was peaking closer to 18-19 PSI. Just wanted to see if anyone notices any glaring issues with these logs.

Thanks for the help!

Some setting issues here... Set dutybias all to 50!

Well that made a hell of a difference...

I see my boost tapering off a little bit in the new logs. Does this decrease look sufficient enough to be a potential boost leak or is this much of a drop off to be expected?

Third gear boost limit is set to 2psi...set it to zero.

TMAP is set to 15, set it to 5.

FF is maxed out due to the previous settings. Set it back to 80 and if it maxes out again, you probably have a boost leak. Maybe the line disconnected from the exhaust flapper? Could also be a legit boost vacuum leak, will have to see.

Third gear boost limit set to 0. TMAP set to 5.

Set FF back down to 80 but it crept back up after the two pulls I did. Updated logs below and attached. Please let me know your thoughts, and can someone confirm THE BEAST's point about setting TMAP to 0 and logging to 5?

Yes, meant to say TMAP to 0 and 6-cyl timing to 5.

See above, trims are pretty high and for running that aggressive, I'd recommend doing the E85 BEF and run an E50 mix.

Alright so here we go...

Added the standard E85 BEF. Also topped off with a couple extra gallons of E85 to bring me closer to E50 (next time I fill up I will be sure to measure exactly what I'm putting in).

Switched TMAP to 0, and then logging to 4 as I have a I8A0S DME (early 2008 build).

Accidentally took a pro log instead of a basic, but I'm assuming that will just help further. Turbo lag seems like it is almost non-existent which is amazing, but I see I am not hitting quite as high of a boost level. Let me know your thoughts!

Log looks okay...best to do them in 3rd gear as adaptions don't take place in 2nd gear.

Just wanted to thank you guys for your help these last couple weeks. Car ran on a damn rail and the runs couldn't have been any more consistent;

12.51 @ 114.4 MPH
12.67 @ 112.9 MPH
12.68 @ 112.0 MPH
12.68 @ 111.3 MPH
12.78 @ 113.5 MPH

https://www.dropbox.com/s/3poa6l6k7f...13533.mp4?dl=0

So I'm thinking about snagging some Mickey Thompson ET Streets for the rear and pulling the back seats out... but any other suggestions to get me improve on this and break me into the 11's? Turbos will also be coming shortly...

You could always try to up boost a bit & add a bit more ethanol.

Weight reduction never hurts & is reversible

What were your 60ft times? That's the place where you have the largest room for improvement.

Best 60' was a 2.02 sec.

These are the next steps I'm thinking (in order) to continuously improve times with the car.

-Remove rear seats + any other relatively simple weight reduction
-addition of 3.5 bar MAF so that I can keep increasing boost levels
-add BMS anti-lag to launch slightly more aggressively (I know this won't help too much with an AT car on stock turbos)
-Mickey Thompson Street ETs on the rear with slightly larger sidewall- currently running Continental Extreme Contact DW 285-35-R19 (open to other suggestions)
-increase amount of e85 and upgrade to stage 3 FuelIt LPFP
-Turbo upgrade (still deciding on stage 3 twins or a top-mount 6466)

Anyone have any other thoughts on the progression of this build and if there are any suspension mods that could be beneficial?

Brake boosting to around 2k to 2500 RPM and then flooring in sport mode. Track was pretty poorly prepped so grip was an issue for everyone, even the all wheel drive cars. Could manually shifting a particular way decrease my 60’?

Before you do any of that stuff get some sticky tires and go back. You should be able to get the 60ft times in the low 1.7x or high 1.6x and that will drop .5-.6 from your ETs.

Do you have any suggestions for the rear tires? I was thinking the MT Street ET’s as I can get a couple that will fit my existing 19” rims and I want the car to keep a more mild street car look which kind of goes away with 15” rims and slicks in the rear.

Actually just ran it in auto/DS. Will a method of manual shifting yield a better time?
