ignition timing and performance

11-12 degrees @4500 on pump
19-20 degrees @4500 on race gas files

Sounds about right.

Now I personally will hit close to 19 degrees on APR 93 with enough E85, otherwise it corrects hard to say 12-13 at best. But this is Stage 1 so i’d expect to be 1-2 degrees above Stage 2 at least.

Lets look at an APR 93 Stage 2.

In Moogas’s July log (after adding race fuel) he appears to hit ~18 degrees @4500rpm and no correction. On APR 93 (correct me if I’m wrong Moogas).

This is in contrast to his original log on pump gas (that Mike borrowed) where timing was WAY down near the range you posted above but with up to 8 degrees of knock correction going on. Obviously there are variances here but that’s a swing you can’t ignore IMO.

You tell me what you think

How about you post your 93 logs finally and we can talk about that. Isn’t that what you want

Include a log with RPM, MAF, IAT, ignition timing angle and IM pressure. Show as many tune files as you have (stock, 91, 93, 100)

Do you have EMCS file switching or are you a 13+?

It is entirely possible that moogas has the 100 file - it tracked perfectly to any of the APR Stage II v2 100 octane file logs I’ve seen. I’ve seen his log, but it didn’t have any MAF or IM pressure.

Edit:
Here’s a deal: I’ll karma you for every day you post one of your log files. I’ll smite you for every day you don’t, thus 20 days and you’re gone. Others may make this go faster.

Maybe some of y’all were getting tuned when all that APR shit was hitting the fan, and someone wanted to leave their mark, so to speak, on their soon-to-be former employer.

It’s very weird how you’ve asked him for some data nearly 10 times and all he has done since is deflect like crazy.

When he asked drob for some data, drob posted it next day, and when it conflicted with azt’s theory, instead of accepting that he was wrong, he chose to call drob a liar and insinuate he doctored up the log.

I don’t know why anyone is bothering with the guy after that. He’s already on the smite train.

Now that I have the interior of the car set up how I want with everything clamped down, I’m going to run some logs at a future track day on REVO 1+. January at the latest. The Surface Pro 4 looks like it is not total garbage and will suffice - I believe this will fit in the glove box. Is the wifi OBD2 RossTech setup the one to get? It’s like $399 or whatever.

This is the first time he asked for a log from my Stage 1 car. The other guy he asked 4 times about had posted the relevant data in an AZ thread and I thought he could find. He couldn’t so then I linked to it. It’s really not that weird.

Drob actually hasn’t posted a log yet of both actual timing+correction (both of which relate here). And I never called Drob a liar. Drob, sorry if I insinuated it. It isn’t easy to trust someone you are being flamed by but I have concluded you are an honest guy.

It is pretty clear that people are still just bent on picking me apart than move forward with any constructive discussion on real data. So what’s the point of me sticking around and entertaining you? Right.

I have the surface 3 for logging, it’s actually pretty decent. But I think it sucks without a keyboard, which is another $130. The surface pro 4 just came out a day or so ago and is much more expensive. See if you can find a surface pro 3 on discount, that’s the best bang for your buck. I will probably get a surface book because I’ve decided using a tablet for a laptop kind of sucks.

I’m just asking you to post a log. I finally saw moogas’ log but not thanks to you. And it didnt have any load data.

Now that I know you have the same thing, why can’t you post one? You just talk about it.

You can just leave like you say, and then at least we know you weren’t being truthful about having those logs in your car.

Post them, hey, maybe we can help you. It’s easy. If your log looks like moogas’, then having everyone have a look will definitely help you.

It didn’t?

And sure I’ll be happy to get you a Stage 1 log from my car when i get home. I got the impression people here were more interested in Stage 2 logs for any further investigation (since that is what they run).

You guys are talking about separate logs.

OK. I’ve been looking at the log where his timing approaches race tune levels like we’ve been discussing.

post that one…isn’t that what I asked you in the third or fourth post? the one you made the graphs from and referenced a data point?

That’s the logs that looks like 100 tune.

And yes, post one of your stage I logs - I thought you already had one. Why do you need to make one tonight?

My VCDS laptop w/log files is at home. It’s a weekday and I’m working. In the meantime you have no comment on other data right in front of us?

tsivas27 provides typical timing values of Stage 2 (4500rpm and peak):

Moogas APR 93 log from July:

http://i64.tinypic.com/2iicrja.jpg

Would you say that is closer to pump or race fuel timing? This is after he added race fuel to address the heavy knock correction he saw on 93 gas that was lowering his timing back to more typical 93 values tsivas27 mentioned above.

Not sure if anyone cares, but I grabbed a couple logs today. This is APR stage 2 with the newer v3.1 tune. Good 93 octane. ECS intake, AWE exhaust. Alpha coolant system. No TCU tune (car was shifting at 6500-6600 for whatever reason today). Ambient pressure was 98kPa. Ambient temp was around 80F. Timing topped out at around 18 degrees with no knock correction.

Here are two from several months ago with the older version of APR tune (v2.x ?). Same mods. It was a little cooler out at around 65-70F, and I think I was using the same gas. Timing topped out in the 14 degree range that day.

I wish I could get more of this timing you guys are talking about… :frowning:

Edit: I should add, and I said this the other day, I am pretty happy with the way my car is running. Much better than say a year ago, but a little extra timing would be nice. The logs and 1/8 mile times back this up. Hopefully I’ll make it to the 1/4 mile track next week. My only issue is with the TCU short shifting on a pretty regular basis now. It wasn’t doing it very often before, so I am guessing it isn’t completely jiving with the new APR tune. I am leaning towards the TCU tune now that it sounds like the hangups were more on the ECU side.

GIAC stage 2 v2 on B8.5 with TCU tune. Car had a Roc-Euro intake, and an exhaust (AWE?). No coolant system. 93 octane. 65 degree day or so, but this was on a dyno. Timing topped out around 16 degrees.

Newer Revo stage 2 (1+ for them) tune on B8.5 with TCU tune. Car had a Eurocode intake, no exhaust or coolant system. 93 octane. Same 65 degree day or so, and on a dyno. Timing topped out at 23 degrees.
