There are a few things I'll comment on later . . .

Dude, your graph says retard.

+1

I like the pretty one with all the colors

/me crawls back in the corner and waits for the turbo trolls to come out.

P.S. thats a Bleep load of timing retard. A safe tune for almost every other manufacturer in the world would be around 0 -2 degrees of timing retard. 6-7 is stupid. Sounds like the timing is too agressive, and I for one don't think its the best idea to let a couple of knock sensors TUNE my car on the fly so it doesn't frag a ring landing on my piston.

agreed. Run better fuel, change plugs, or use the SPS to back off the timing a little.

Nope, I think it's so painfully obvious, that Keith will kick himself if he doesn't jump in and say it!

/me sits back down in the corner.

I should do some timing logs on my APR 91..

Ok, come and get some popcorn and guiness over here in the corner You too Anand!

Why? This is perfect...

You passed him a girly "appletini" instead..

Quick reference to my data logs with APR 91 oct file, where I had less then 2.5 degrees of timing pulled, and nearly nothing until above 6,000 rpm. Oh... and that tune dynoed at 214whp and 247wtrq.

Toasty!

I dont feel as worried about my lower boost numbers anymore..

That's with a quick spike to 19psi. Boost graphs can be seen in that link too.

Anyways, back on topic.....

Don you didn't pull that much timing pull even when you ran 91 octane on the APR 93 octane file

I remember distinctly that you claim egt's calculated from the o2 sensor are bunk and now you try to use it to discount a competitor..

What exactly is your job again? Minister of Disinformation?

I do agree that the timing pulls are a bit much. However, I would appreciate the OP giving his 3 Revo settings. I get the feeling they may be a little aggressive for the fuel he's running.

I'm sure that the EGTs through Vagcom aren't an accurate way to tune, but that doesn't mean it doesn't give us an idea of approx. where things are.

And I do believe he said he's running 93 octane. Other then race gas, it doesn't get much better then that in most places.

Running full REVO stock 93 settings. Verified by SPS & etc . . .

Timing 5, Boost 6 Fueling 9

These are actually the settings that the SPS uses when you select 93, not the advertised 5/7/9 that REVO was mentioning.

Dave

good to know. So are you going to change any of these setting to address the timing pull? I am running 93 octane with timing 3, boost 6, and fueling 9 I do believe and when logged I didn't see that kind of timing pull...

One thing that may be good information is that generic SPS settings like 5,7,9 do not mean this is the perfect setting for your car just because you run a certain octane. Logging like Dave did is key to getting it how you want it. Anyways, nice information Dave.

Well If we are in fact going to start using the O2 sensor approximation then I say fine. As pointed out by Kieth@apr in another thread the max egt for the K03 is 920 C, so according the Kieth Revo is doing just fine.

Of course how we'll have to argue what kind of buffer to have from that max temp, but all in all it would just be a bunch of gum bumping.

Only issue I see here is the timing pull, and with a little tweaking i think it can be fixed.

Exactly. Would be nice to see timing at 3 and boost at 7 for that car, but it sucks that fuel is already topped out at 9. Could help with egt to get even more power. Dave, would you consider doing logs on the same ambient conditions with the same fuel on different settings to see how your car adjusts with each setting?

The shop that tuned my car claimed that the 2.0T FSI can't run at anything other than the 9 setting. He told me only the MkV R32 would have adjustability in that fuel setting with Revo. So in a MkV GTI the end user can niether increase nor decrease this setting.

Just what I heard.

Well, in the tuning world it only takes a few good posts to see changes made so maybe there will be more adjustability on this in the future. I DO NOT want people using the followig log to bash a company but here is a comparison EGT on my car with exhaust and chip.

It is possible to get EGT up even higher on the track due to mulitple on and off throttle transitions so this is just a referance doing a single 3rd gear pull.

If I'm not, I wonder what the impact would be on power/torque vs the standard Revo settings by running the Revo-reoommended boost and ignition settings but stock (richer) fuel trim? Wouldn't it also stand to reason that one could potentially make up some of the lost power from the richer fuel setting with more aggressive timing since the richer fuel mixture should allow for more timing also?
