Define fast, I wouldn't agree with that statement at all. There's plenty of fast motoronic cars.

OK I'll bite Smiley

Up until recently (maybe even still/currently) IMO the way ME was being tuned was not allowing the full potential of the cars....

Still to this day, there hasn't been faster B5 S4's than the ones running on standalone.

Most standalone cars seem to go faster with less/equal parts (ie. Sherrif's car)

My friends 2.7T w/ VEMS on both K03 and China K04's was stronger then almost any other B5 S4 stg3 or otherwise I've ever been in.

Don't get me wrong... ME cars show "power" on a dyno... they just don't seem to perform up to the numbers most of the time.

Going to need more than that. What, EXACTLY makes this magical standalone so fast?

If you can't answer, no amount of dyno handwaving bullshit means anything.

I don't know what it is... I'm going to guess TQ management maybe....

FYI, there seems to be a similar trend of this happening with BMW 335's on stock ECU's... single turbos, etc... all making 600-700whp... all translate to crappy real world performance vs their measured power output.  Is it the same thing?  Not sure.  But it's another example I can come up with.

You can see based on my examples what I think it is... would be other factors, who knows.

Fact is, GURU's trap speeds (and 1320 times for that matter) on 93 octane pump fuel (no meth) haven't been matched as of yet with a car running Motronic.  Sherif's car was also trapping higher than most other cars with similar hardware.  Both cars are/were on full standalone ECU's, both cars running just pump gas.

I know SnowTroopers car is fast, it also has awesome stuff in it and an awesome turbo.  Not everyone can build a fast car, nor can everyone drive a fast car fast.

There are however plenty of high HP B5 S4 littered over the internet, could it be that every single one of them is an absolutely horrible driver to be missing so much off the fastest cars?  Possible maybe... but doubtful IMO.

So uh, timing? Really? That's it? Just timing?

You want timing, turn off KR.

Sorry, this is all bullshit until somebody posts something real, not internet dick waving.

Unfortunately, nobody seems to want to post logs, just non-stop bullshit.

If you can't quantify the gains with actual data and objective facts, stop claiming.

Bottom line, this is a bullshit question to start with.

If all you want is a car that can only go really "fast" on race gas (or e85) rowing through 3 or 4 gears WOT, then all you need is a basic standalone ECU with what, a dozen maps?

Any dipshit can tune that; you just need solid supporting hardware, which is why it is a popular route.

Tired of it; it is a waste of time debating this shit, because it invariably centers around arguments made by complete idiots.
