dyno graphs (yes, my Avant is tuned and making good, streetable power)

We are back in business!

Gasketless T25 flange FTW! So far no leaks. My 'machine work' of the flange appears to be holding. Gonna go take her for a spin and shake things down. Then bedtime.

[sean1.8t]

yep, gaskets FTL.

only gaskets you need should be touching the head directly.

[Don Supreme]

tempting.

[dougyfresh]

Oh, I also got rid of the gasket on the turbo outlet to HFC.

Did a few 2nd gear pulls last night.

IDC is around 82% at 6700rpm (if my calcs are right). <-- Why I don't see anyone with a 30series running 630s.

Timing curve looks good... for now. CFs are 0 right now thanks to the super cold ambient air.

than timing isnt good enough!

'for now'

I/we are still tweaking things.

Also keep in mind its cold out right now so if I'm pulling 4s or 5s now then I'll be upwards of 8s and 9s in July when its 100+F out. That is what Lemmi is for and why I added timing this morning...

IMHO, the injectors aren't the problem.

Doug, when does the ms109 go in?

I know your thoughts about the fueling. Someone's gotta run some tests with changing the hardware for us to all really 'figure it out'.


I'm picking up 10gallons of Sunoco 112 at lunch today. Draining the 93 out of my tank tonight after work and then I'll add a bunch of Lemmi tweaks and do some logs with 112 in the tank. Dyno on 112 tomorrow.



EDIT: Got Sunoco 110. Fcvkers ordered me the wrong fuel. Shouldn't matter anyway.. It is so hard to get decent help now-a-days. I swear.

[dougyfresh]

Friday night Greg (actlsub9) and I logged the Avant extensively with some 110 in the tank and my 93file on the ECu. We did a baseline pull with no timing adjustments and the gas in the tank (after driving it a bit). Then slowly increased timing advance via Lemmiwinks. Did 3 to 4 WOT pulls in 3rd gear of each setting after driving it a bit in each setting. Over 20 pulls in total and we used up all 5gallons of 110 I put in the tank (guess I like data )!

I was looking at the absolute timing curve and the correction factors associated. Figured CFs in the 4-5 range were acceptable as long as the timing curve looked good. The goal was to get the curve as high as possible from 5rpm up to redline. My thoughts here was that this would ensure the most amount of power possible given what I had to work with (file on ECu and gas in tank).

Here is an overlay of all the settings we tested including baseline. We chose what seemed to be the best curve from each setting. Each pull within each setting was very close to each other. The pulls were done with a minute or two inbetween. Factors such as road, traffic, how long it took me to copy and paste, look-out for police, etc... played a role as to the time between pulls.



We settled on the +8.25deg curve. Why? That seemed to net the best amount of timing advance with what I had to work with. CFs were in the 4-5 range. It also holds more timing from 4.5krpm on up when compared to the +10.5deg curve. The +10.5deg curve also netted CFs in the 9-10 range which was a little too risky for me. Esp knowing the ambient temps during our pulls was around 27F and the dyno room on Saturday would be in the mid-30s (estimated).

Asleep sometime after 2am. Wake up around 6:30-7 to take care of the dog and put another 5gallons of 110 into the Avant. Off to caravan down to EPL in Stratford.

The best part of the trip was the short tunnel on the Merritt parkway. All four of us got on it in that tunnel. Sounded like a racetrack. It was music to my ears.






I was the 3rd car since a few people weren't there yet. All three pulls were within a 5min span and they overlay right on top of each other (repeatable!). I didn't log the car while on the dyno and am kicking myself for it. Would have loved to overlay the timing curve from the dyno with my logs from the previous night.


Right about where I expected to be. The power curve is the same as my 93file but offset given the fuel and timing tweaks. Holds pretty steady out to redline . We did not continue up to 7400rpm since it was somewhat steady and tapering off. Torque curve is huge but dies rather quickly and at a faster rate than my 93file with 93oct.

Now this isn't a direct comparison with the ASP dyno since I tweaked my file a bit but you can definitely tell both dynos read about the same. Makes sense since they are the same brand and are running the same software.

late day R32 tweaking...


I got to meet both Tony@EPL and Jeff@C2Motorsports. Both guys are extremely knowledgeable with Motronic. I recall having a great conversation with Jeff about his latest gen (turboed) R32 that he's tweaking and writing software for. Pretty impressive the stuff he's doing.

d-d-d-d-dayum!!

+10.5?? is that degrees, or "points" on lemi that you bumped it?

car is looking good doug, awesome work!

That was the 'adjustment' via lemmi. The lemmi screen labels it as 'degrees' but it really winds up being a voltage offset within the ECu to net the resultant timing curve. Right, Greg?


I'll plot the actual VAG-Com logs if you want later tonight. I gotta go to work now.

Thanks.




Last night, while leaving work, was the first time since getting the Avant back where I've started it up in extreme cold after it sat outside all day (it sits in my garage at night and probably only gets to 30F in the garage). 15F out around 7pm and I turned the key. Car fired right up on the first crank and idled perfectly! It was so effortless and smooth I forgot the car isn't stock anymore. Last winter I used to get misfires on start-up and extreme cold starts it would stall out. Not anymore. It was so comforting to know that I don't have to worry about anything and/or really carry my laptop around with me.

[sean1.8t]

that's cool and all. but FWIW, i just started my car ~30 minutes ago. started right up first try and idled perfect for normal cold start up @1200rpm. about 20* outside

That other black s4 was me! I was supposed to join the rest of you in the a.m. but I couldn't seem to wake myself up. I'm sorry I never introduced myself to you.
That tunnel is my favorite part of my daily commute; it makes the drive much more tollerable.

thats some power there MR.

ASP Dyno Day round 2!

ASP Dyno Day round 2!

I need some software tweaks but I doubt it'll happen before Saturday so I think the WG is going back to 11psi.

[a4wd]

Nice numbers !!! I soo wish i had the dough for a BT let alone a stroked B6. One thing though, you dont mind having your full name on that dyno sheet? With such a nice B6 you never know...
