Audi A4 1.8T Quattro, AEB, MS3X

Post by eMTea »

Hi!

After a weekend on the ice, on an arrangement called "Autopower on Ice 2013" with no problems with my car, I want to add it to the Success Stories of this forum.
The build thread of this setup you can find here: http://msextra.com/forums/viewtopic.php?f=131&t=47244

The fuel map is not 100% fine tuned to match my AFR table, but the tune is very driveable.
Ignition map was tuned on the road in 3rd gear, and with knock listening headphones. The torque flatted out before knock was induced above 3000rpm in boost, the most sensitive area was about 2500rpms,

Setup:
MS3X fully sequential. (COP's driven by Quadspark module, GM 3bar map sensor, Innovate LC1 WBO2)
Stock 1.8T AEB engine.
Siemens Deka 630cc injectors (728cc @ 4 bar, as in AEB)
KKK K03 turbo. (1.2 bar of boost, @ Open Loop 65% setting)
3" downpipe, no cat.

Good, good :) Any videos of the fun?
I'll check you MSQ when I get home.

How much boost do you run?
That amount of ignition at the top is safe for you?
Still on stock everything, right?
Why is that line @120 that low compared to before and after?

Cheers!

I run 1.2bar (17psi) of boost at the moment.
If the msq contains a drop in the ignition advance table, I may have uploaded the wrong one, I'll correct it.

I actually had 2 more deg of advance from 3k and 140kpa, but it did not increase power, so I backed down to where it is now. I just interpolated the 120 line between 100-140.
No problems, no knock :)

I have some inboard video, but I'm not satisfied with the quality, I'll see if I can polish it an post in online.

EDIT: Uploaded the latest MSQ now :) And trying to make some useful video.

This was all I managed to fix, but at least possible to see some of the fun :)

Nice!!
That has to be cool :D
When the car spun, and you "hit" the snow. Does that harm the car in any way?
Is that a frozen lake, or a road with a bunch of snow on it's side?
Nice job :P Pics of the car?

It's very fun :)
It's on a frozen inland water yes!
When I drift out, outside the ideal track, my 200ish HP can not keep up the speed, but no damage, only 5cm loose snow. But if you go out in the edges, or in the inside of the corners, you'll likely break something, those edges are only 30-50cm, but they are frozen ;)

No pics of the car, but it only looks like a stock Audi A4 anyway :P

Anyway I could see your MSQ? Currently having some troubles with mine and taking a look at yours might provide some insight. I posted in the MS3 section for some help but my post has to be reviewed by a mod before it will show up.
