APR Stage 3+ logs; have at it...

[rxrep]

All logs are WOT 3rd-gear; I couldn't get 4th gear because I couldn't get a stretch where I could pull and log at the same time without killing myself.
I did try for one log from dead stop through redline 4th gear. But I managed to be an idiot and never actually hit "start" on the logs. And it was scary because I ate up road way fast and according to my GPS actual speed, I was at 127mph at 6600RPm in 4th gear. With a bend in the road coming up, that was nuts. Brakes work good, nonetheless.

First, here are the unitronics settings... the fuel trims are nothing but what Unitronics suggested on Vortex. The timing is +5.25 as you can see.




Here is BTDC, CF, and block 032 Lambda. What is up with negative Lambda, and what does that mean?



Here is BTDC, CF, and block 31 Lambda:




Here is Req vs. Actual boost, IAT, and EGT. Note on this a few things. First, I still have a small boost leak. I reached requested boost at 3760RPM but it didn't hold well due to leak. On the IAT the FMIC seems to be doing what it was supposed to as IAT dropped after shift out of second. Ambient was 67 degrees farenheit I think; EDIT: that's 19.4 celsius.. And finally, on both the IAT and EGT, this log was running HOT because I was running the piss out of the car.



On all, I didn't wind out second prior. I had to try to shift, see the road, and hit start on the log. All where almost boggy on 3rd gear WOT and not coming out of a high moving speed from second.

Being that I'm not sure what all I'm looking for but have a general idea, lay it on me. I'm not too worried about destroying anything at this point because I'm just a week or two shy of storage on the car, and this winter will be 2.0 stroker and built bottom. So right now I'm just playing and not worried of the consequences.

BTDC - IS OK........

but you have a lot of timing CF, so I wouldn't try to advance the timing anymore, maybe even take some out.

The negatives numbers from block 32 means the ecu is trying to remove some fuel. Those adjustments are low so nothing to really worry about there.

[rxrep]

Yeah, I'm going to take it back to +4.5 and see. Vortex 1.8t VW guys are telling me that CF's aren't high or excessive until you're at 8's and 9's, lol.

[Silence]

Actually, that looks pretty damn good. Timing is real nice, and lambda is spot on.

In your first log, 032 is long term fuel trims, and shouldn't be logged. Just a block to show you how much fuel the ecu is pulling or adding over time. Only negative thing I can say is you FMIC doesn't seem as efficient as others. Which is it?

Thanks. The FMIC I'd say is as efficient as it could be. At the point of these logs, I'd been running it like I stole it for about 2 hours. I pulled over at one point to turn off laptop and d/c VAG COM cable and opened my hood a little and let it idle some, and the heat out of the bay was off the hook. Anyone can log IAT as first pull. To be able to get pretty much ambient soon after shifting out of 2nd, after a few hours of balls to the wall, is pretty good. Yes, it maxed a little high, but still maybe within 10 celsius of ambient. Which for the running I was doing, I'm happy with. It's way better than it used to be, for sure. I'd be way up over 40 celsius on every gear. Now I barely, if ever, go more than 10 celsius over ambient.

Oh, and you asked which is it... meaning brand? If so, Racetec.

[Killerteve]

I like seeing that full boost around 37-3800.

[infernocl]

because we have high compression, the car runs hot with 12.5:1, dial it closer to 12:1. that should remove any cfs on there

also add to ch3 as well since there could be decreasing load up top (smaller maf/rpm) ratio

8 and 9s are pretty scary. Esp with ambient temps right now in the 50s and 60s. Those 8s and 9s will get up to 12s in summertime. I believe 12 is the max the ECm can pull unless that is adjusted within the tune itself (I doubt it with APR).

4s and 5s are acceptable. I pull 4s and 5s all the time.

I'm gunning for winter temps. Today we hit almost 70 and ambient at time of that pull was 68 farenheit according to weather.com, so as it cools off over the next few weeks the CF's should read a little lower. This isn't a timing setting to stay; I actually found out when I did a "read SCU" function on Unitronics to get my baseline from my last tweak, that I was at +3.75 over the summer. I know I was at +6 last winter when ambient was always around 0 celsius.
With APR 93 file and no Uni tweaks I pull 0's all day long in every weather. Was getting sick of the generic tune so that's when I started messing.
I'm happy keeping 2-4's with peaky 6's here and there. Right now I'm just trying to learn more about how the settings effect the logs, figuring if I blow something now it doesn't matter because I'm pulling the block over the winter anyhow. So if I learn the in's and out's now, I'll be golden next summer.

2-4s with peaks of 6s for a given set of ambient temps (aka: winter) is good stuff. I know you know what you are doing. I was merely commenting on your vortex quote.... Don't believe the hype.

Why are you pulling your block next year? Out of curiosity, what are your intentions?

[rxrep]

I know you know what you are doing.

You have more faith in me than I do then, lol. I knew where to shoot for as far as CF's, but I'm still learning on BTDC and Lambda.

Just to clean.... lol.
No, actually, I'm joining you in the 2.0 stroker land and building up the bottom end. If you can't beat 'em, join 'em, I guess.
As for hair dryers, I'm holding off to see how all you BAT people are doing over a little longer of a period.
I like where my full spool is now. I don't live where there are very long straight sections of road, and it certainly isn't flat. I want low torque and quick spool that holds to redline. I rarely make it to 5th and 6th unless I'm out on some highway.

[dirtybrd]

He said built 2.0.

Lee, you have my cell # still? Hit me up, got some 2.0 info for you

Logs look good, actually makes me feel better than even the 3+ doesnt and cant run a bunch of timing.

[actlsub9]

Your making it way harder on yourself then you need to. Get into third, coast at 2k, hit the start button while your coasting and then floor it when your ready. You can always delete data later on. I start logging way before I do the pull.

BTDC is your timing advance recorded in degrees before top dead center. This is when the spark plug fires in regards to where the piston is in the travel coming up to top dead center. Measured in rotational degrees of the crankshaft.

My 2.0 with a 2871R has the same exact spool as my 1.8 with a GT28RS did (where you are at right now). Avant is getting tuned. Give me a few weeks and I'll have some logs, videos and dyno graphs.
