Not really. As long as you get the shape of the curve, you can pretty much estimate with enough

accuracy. VAG-COM's sampling rate of about 3/second is fast enough to get the shape down. It may not catch peaks of MAF flow, boost, etc, but it certainly has enough resoultion to capture acceleration runs. Hence I was able to calculate timed runs, even without having the exact RPM in the VAG-COM log.

FATS test, what are you girls getting for numbers, stage 2 and stage 2+ cars - Milpitas2.7T 2004-05-28 00:52:32 (338 views)

Okay I'm running stage2 on 91 octane in 85+ temps 4.8-4.9 consistently. - Milpitas2.7T 2004-05-28 12:16:39 (119 views)

Stage II with or without FMIC, and is this also without any intake mods? - mpwolf 2004-05-28 13:17:45 (72 views)

stock air box, FMIC.. I think the FMIC will yield better results when I swap code - Milpitas2.7T 2004-05-28 15:42:54 (89 views)

You know, I think only APR Explorer recorded times should matter. - Jason @ ND 2004-05-28 11:08:14 (73 views)

rpm vs time is SO nearly linear, even large rpm/timing errors are irrelevant... - nyet 2004-05-28 12:58:31 (87 views)

Not really. As long as you get the shape of the curve, you can pretty much estimate with enough - mpwolf 2004-05-28 11:15:48 (346 views)

Disagree. When comparing tenths to determine performance, using software... - Jason @ ND 2004-05-28 11:23:04 (120 views)

Well, it's not really error. I mean, if a time value and an RPM exist in a VAG-LOG, it IS what the - mpwolf 2004-05-28 12:51:05 (176 views)

I'm fine with your calcs, point is others are probably not doing that to reduce error margins. - Jason @ ND 2004-05-28 14:57:08 (67 views)

That's cool, hopefully I've left enough information in this thread so that others might be able to - mpwolf 2004-05-28 15:09:17 (81 views)

Not an ECU limit, but this is very odd, ECU explorer - Milpitas2.7T 2004-05-28 17:20:30 (98 views)

Wow, that is strange. - Doc@PEB tuning 2004-05-28 22:04:40 (65 views)

Interesting, so ECUx is recording fractions of an RPM? That doesn't seem right. I wonder how APR - mpwolf 2004-05-28 21:58:08 (88 views)

NM, I'm drunk, I'll look at it in the morning. - mpwolf 2004-05-28 22:03:51 (67 views)

40*255=10200 - nyet 2004-05-28 15:14:28 (95 views)

I need this tool too. My log samplings are every few 10ths at best, one block set. - Hal_S4shizzle 2004-05-28 12:26:23 (75 views)

You're not missing anything for FATS acceleration runs, read above. - mpwolf 2004-05-28 12:52:19 (72 views)

Agreed but I would like the finer granularity for tuning/tweaking. - Hal_S4shizzle 2004-05-28 12:54:07 (68 views)

Definitely, I was only referring to Jason's statement that we should only use ECUx for timed runs. - mpwolf 2004-05-28 12:58:54 (64 views)

Jeff or Jason? - Doc@PEB tuning 2004-05-28 13:00:00 (70 views)

Guess. - mpwolf 2004-05-28 13:01:57 (58 views)

Hey, you are the one who wrote it....not me :-/ - Doc@PEB tuning 2004-05-28 13:02:30 (70 views)

2nd that. - Doc@PEB tuning 2004-05-28 12:27:26 (50 views)

Agreed LOVE my Explorer!! Love it love it, but I need knock sensor activity and it's not in here! - Milpitas2.7T 2004-05-28 12:13:21 (55 views)

Correct me if I'm wrong...but the proper test is... - Racked (d18b) 2004-05-28 11:02:41 (108 views)

The test is actually 4200-6500. You should start in the 3,xxx rpm range and end beyond 6,500. - Doc@PEB tuning 2004-05-28 11:04:50 (94 views)

2+, 5.10 sec. w/MBC keeping spikes in check. - sj6spslvrS4sdn 2004-05-28 10:20:30 (77 views)

I'll have to verify with Piggie... - QuaD@PEB tuning 2004-05-28 07:56:13 (127 views)

Stage II (updated with three consecutive runs, per J. Moss's question of repeatability) - mpwolf 2004-05-28 07:28:47 (276 views)

Nice presentation. :) - VonK :: Indukted 2004-05-28 07:36:29 (80 views)

Do you consider anyone with k03s, DPs, and exhaust stg 2+ no matter what else they have? - Doc@PEB tuning 2004-05-28 00:54:50 (426 views)

Awesome MAN!!! I wish we had 94 here... - QuaD@PEB tuning 2004-05-28 06:44:23 (100 views)

Good numbers. As with Jeff would like to see it run at 65-70deg ambient. - Hal_S4shizzle 2004-05-28 05:07:32 (126 views)

For discussion's sake, here are my runs above, using 4200-6500. - mpwolf 2004-05-28 07:50:01 (169 views)

Thx. I lost my AMS pulls that Jake did. Don't remember doing FATS times on them but the - Hal_S4shizzle 2004-05-28 10:35:26 (76 views)

That is very fast for 2+ - - J.Moss@TorqueFactory 2004-05-28 00:58:51 (196 views)

jeff, TJ (and an update) - nyet 2004-05-28 12:27:26 (127 views)

Sounds good Nye. Will be pretty slammed until Thursday. - J.Moss@TorqueFactory 2004-05-29 09:55:16 (74 views)

It should be with RS4 ICs, EFK, manifold spacers, MBC, TCD, and whatever else Mike is testing. - mpwolf 2004-05-28 07:58:05 (71 views)

That's all of it. Nothing else. Lots of other cars have all this stuff too...... - Doc@PEB tuning 2004-05-28 08:55:58 (111 views)

Ported/polished manifold? - mpwolf 2004-05-28 09:05:55 (69 views)

Sorry, I just assumed that was implied with the spacer since most do that together. - Doc@PEB tuning 2004-05-28 09:15:32 (63 views)

A midget behind the wheel counts as a weight reduction. - Verr�ckt 2004-05-28 09:01:48 (74 views)

Agreed. Now get in the car <ctrl 7> - Doc@PEB tuning 2004-05-28 09:03:28 (67 views)

Leaving in 15 minutes sir. - Verr�ckt 2004-05-28 09:04:41 (78 views)

Sweeeeeeeeeeeeeeeeeeeeet! - Doc@PEB tuning 2004-05-28 09:05:11 (72 views)

He is more like Stage II+++. - Verr�ckt 2004-05-28 05:38:26 (172 views)

It was in the 30s when I pulled that. I pulled another sub 4.5 the same day. This was 03/18/04. - Doc@PEB tuning 2004-05-28 01:03:20 (133 views)

That is smoking. Would love to see how it runs at around 70f. That is much more comparable to what - J.Moss@TorqueFactory 2004-05-28 01:06:40 (154 views)

Sorry, I guess it was actually 03/19/04. Here is a graph of 003 on the other sub 4.5 run... - Doc@PEB tuning 2004-05-28 01:15:39 (180 views)

I know we talked about this before...(edit) - s4IRIsH 2004-05-28 11:13:00 (71 views)

I have no logs of timing correction/knock voltage, but it is not an issue on my car.... - Doc@PEB tuning 2004-05-28 11:33:08 (96 views)

Thanks, what plugs are you running? - s4IRIsH 2004-05-28 11:48:00 (73 views)

I have the Bosch Platins. I've had them since ~12k miles. Got too good of a deal to pass up. - Doc@PEB tuning 2004-05-28 12:05:21 (79 views)

Free ; - p - s4IRIsH 2004-05-28 12:21:06 (74 views)

:x - Doc@PEB tuning 2004-05-28 12:21:42 (68 views)

Yep, I'll get some test done in warmer weather. 30 degrees is like cheating IMO, but he asked ;-) - Doc@PEB tuning 2004-05-28 01:08:34 (103 views)
