To VAG-Com users, FATS times database for the Euro S4s

[JonnyX]

I think so, and MRC have had a fiddle, but there is definately more to come, as I'm running a mere 1.29bar peak and still have all my cats and dogs

Oops, that should've been 1.39bar peak

Are you sure it wasn't 1.4?

[MarkB]

Did another run in my S4 and got...

The last 2 columes are boost requested and actual. They look ok but the maf reading still looks high to me.

FATS time was 6.5 seconds again though obviously not so acurate with the extra channels logged. Is 6.5 seconds OK for AMD mapped with a Miltek Cat back exhaust?

[Nige_RS4]

Mark, 6.5 is about right for a std S4 - you should be in the region of 5.5 or less! I take it the 3rd column is the MAF reading - it does look a bit high - I've never seen one read high before, speak to Minhea at MRC and get his opinion.

[S2tuner]

Mark, your high MAF numbers come from excessive boost levels for K03 turbos, look at your timing and compare it with other cars that have posted logs, you're running 5.3 degrees advance at 4700 and 5000 RPM, this is way too low.

Basically you're running very high boost which flows lots of air, but the air is so hot and the backpressure before your turbines is so high that the engine chokes and can't produce power because it can't run decent timing advance.

HTH,

Mihnea

[MarkB]

Thanks Mihnea, I think that does help. So hopefully I have no boost leaks but the map is crap.

I wonder how long things will last like this... are AMD maps normally like this?

Thanks

[saf]

They shouldnt be like this on an AMD chip. Although AMD run higher boost on their remaps than most other companies from what ive read on this site.

Did you just get your AMD map mate?

[MarkB]

Car came mapped when I bought it. I'm thinking I'll do some other mods and get a remap...

[saf]

Im going to get a Custom stage2+ done next week from MRC. Im sure Ill be recomending it to you. Willl be much better than a generic AMD map me thinks.

[MarkB]

This was a 'custom' AMD map that showed 320BHP.

[CliveH]

This was a 'custom' AMD map that showed 320BHP.

I didnt know AMD did custom remaps.

[MarkB]

Maybe they don't, maybe they just doing the standard map and tell you what the car is showing...

[CliveH]

Right guys, I've just got round to doing this as I'd like some comparative data before the next set of mods.

I achieved 5.74 and 5.76. MRC tuned stage1, ambient temp 18.5C, 3/4 tank petrol, and just me.

Thought I'd get a bit better than that, but we'll see what the trip to MRC brings tomorrow...RS4 exhaust and gutted precats going on, and maybe another little tweak of the ECU...

[Paulm]

that sounds about right. I got 5.7 before my pre-cats were done. After they were done I can run more boost and advance now my best is 4.53 4.6 was the average of 2 runs

[MarkB]

My first FATS run was 5.94 with an AMD map and Miltek cat back. I must get out and find some flat road that I can go both ways on... Can the pre-make so much difference??

[CliveH]

I achieved 5.74 and 5.76. MRC tuned stage1, ambient temp 18.5C, 3/4 tank petrol, and just me.

Right, did a little run this morning and got 5.63 - this is after my trip to MRC yesterday for fitting of RS4 exhaust and gutted precats and another little tweak of the ECU. (ambient air 18C, just me plus half a tank of fuel)

I expected a little more than that but I'm running Tesco 97 at the moment (there's no 99 in Banbury) and the runs prior to these mods were with Tesco 99.

I'll do another run after I fill up with 99 again later in the week.
