RS6 on Dyno Dynamics Dyno

[makaveli42]

Looks about right. Mine stock, ran a best of 13.27 at 105..with a bad TC.Attachment 14241

i can't get a 1.9 60' with a good TC!!!!

The dyno reads low but that's not the problem. His 1/4 mile time and trap speed are as slow or slower than a stock RS6. It's hard to say if the Revo tune is really that weak or if his car has an issue. That's why you need to get to the dragstrip with yours.

Well the tune is there at least, glad to see that. 6 setting is a bit much boost (~17psi) which can run lean. If the car feels fast maybe the Dyno was off. Did you do pulls in third gear? Interested to see your logs once you get them.

How are you launching it? ESP off or on? What RPM are you leaving at? Are you brake torquing it off the line?

The tune for him cannot be that weak, assuming it actually is affecting the car, he's barely at stock on dyno or the strip. There's no point dogging the Revo tune because something is off. Imagine if your tune was on a car with a boost leak or clogged fuel filter/bad plugs and the user complained it was slow, just saying...

I know the strip gives a real deal result, but the RS6 is massively faster as I have it tuned. And the car is very well sorted.

I can tell you that it was making my brothers 500hp V10 M5 feel a bit slow...that was until the ECS supercharger kit with WM put it into the low to mid 600's, now that is a mean car from the 60-150 range!

I'll go to the strip, you post a data log, I've never seen one from your tune and it would be interesting to see the EGT's and timing. I'm assuming the IDC's will be very high, but wonder if you're maxing them at 100%. More technical interest more than anything...

Any tips for when I do logging tonight? Never used vag com before for logging. I have looked on online manual a bit yesterday but wasn't clear how to get to logging module. Anyone have or seen a step by step for this?

thanks,
kevin

Always start by going to Options, Test, Save.

Select Control Module, then Engine, then Measuring Blocks. A few other details with saving to a log file, location.

Use 3-timing, 112-egt, 115-boost, for starters. 31-lambda can be added in another time, reads the front O2 for fueling. Not the most accurate sensor though, really need a wideband to fine tune. EGT reading is a more direct gauge for the fuel/air mixture.

To upload a log here, trim out all the extra tables. Save as webpage from excel. Open in a browser and select with cursor, then paste into a post here.

btw, think there is def something wrong with car

Save to a file then upload the file maybe?

^ not sure if that helps/works...

[makaveli42]

How are you launching it? ESP off or on? What RPM are you leaving at? Are you brake torquing it off the line?

Esp off and in S mode, tried the duck foot thing but nothing? I'd gas and it's stall around 2200-2300 and it's start creeping me foward (so I know the boost was building) but never felt a hard launch and never get a 1.9 60'. Freshly revealed ICs too and logs look great as far as I was told

[lswing]

Having trouble at last step, i have in webpage but when i copy and post in a reply is just a bunch of numbers jumbled up.. please advise on what doing wrong. Or if anyone can help PM me your email and will just email it.

btw, think there is def something wrong with car

Super tough to read, but maybe boost leak, your egt's are nice and chilly, need to warm them up...seems like a hot good tune will be into the 800's, and hot is a bad thing, it just seems like there could be more power there for sure.

Also, log in turbo mode, way more frequent and required basically, there's a box to check up top in the screen where you select what areas to log.

Ok, so you export from Excel and have a web page right. Open that with a browser, you should see a nice table? Select the table and everything right there on the screen, then post that into your post here. I think it looks kinda screwed up at first, but post it anyhow to see. If it's bad you can just edit or delete the post.

[ttboost]

Looks like .5 to .6bar max boost? MASSIVE boost leak or it's in limp mode. Does it take off OK, then lay over? Does it buck and fart? Try disconnecting your battery for 15 seconds.

does above picture help? Car feels normal from what i can tell, just slowish

So if boost leak.... where to start looking and testing? I have a warranty, wish i could just drop it off and tell them i have a boost leak...

[hahnmgh63]

I forgot but how long have you had the car? Wonder if you have ever felt normal Boost? Way low on Boost but the requested is also low. Revo with setting 6 should be requesting over 2000MB. The Boost is in Absolute pressure, so 1013.2MB is normal sea level pressure. So roughly 2026MB is a 14.7psi of boost above atmospheric pressure.

Have had the car since early June. Car feels same power since day I got it, but I rarely really get on it so maybe I just cant tell. Any suggestions on quick places to check for boost leak? besides DV's (which are stratmosphere so doubt that is issue, but will check)

So if boost leak.... where to start looking and testing? I have a warranty, wish i could just drop it off and tell them i have a boost leak...

Pretty easy to see and hear a boost leak. Do you have somewhere you can drive, next to a wall or jersey barrier..or a fence? You will hear the loudest hiss you ever heard under boost. Check your upper IC hoses..pretty easy to see...maybe use a small mirror to see underneath the clamps. Jack the car up, remove the diaper and check the hoses underneath...very easy to see those from underneath.
