Shiv, have you released the final production version of v2.0.2 for 6AT yet?
I thought it was going to be up Friday night?

Thanks.

Shiv posted today he will post the map once he is at home.

the 335 takes 2 k&n filters?

Boostin, it takes one K&N drop in filter, but if you use a cone style filter with no air filter box, it use two cone filters, one to send air to each turbo.
But, to me, unless there is some way to keep the hot air from under the hood going staight into the cone air filters, I really don't think they will help out on the road.
On a dyno they probably show the gains though, since the hood is up and the fan is blowing air directly into them.

is it safe to say, that a drop in panel filter will get some good gains? or best results, while still using the stock box to keept hot air out but allowing more air to flow?

I agree with D72 here... in real world application i Think the best solution is a proper CAI that sits down in the fresh cold air somewhere behind your bumber or wheelarch etc.

however, it may be that our engine bay IS cool enough once on the move ? i dunno, probably need some empirical testing here to show either way ?

We dyno'd loads of cars today - in fairly cool conditions granted. However i did not see ONE example of heat soak or inconsistant dyno run

So maybe the cone filters are as good as they say...

Your stock air intake should be plenty good enough up until about the 360ish whp range. Above that and it is a definite restriction, as stated previously on the board.

With so many people dialing in their user TQ tables, I figured I do the same on the dyno and show exactly what effects these changes are having. Also took the opportunity to do his on both 91oct and 93oct.

For those who don't know, this dyno tends to read conservatively. Some Dynojets will read 5-15whp higher. Regardless, this is the same dyno we have always used for BMW testing so it is basically comparable to other results we have posted. It was raining yesterday and temps were 68F with CF of 1.02. Pretty normal.


The following results were with Shell 91oct in the car:

Run 176 was the baseline v2.0.2 (default TQ settings of 90%) as it came in from the streets. It put down 346-349whp repeatably. I bumped up User TQ to 92% and did another couple of runs. Run 177 (not shown) put down 357whp with little adaptation. Run 178 put down 363whp. More runs could have improved things a bit more through further adaptation but time wasn't on my side. But just +2% made a substantial change. I'd say that us 91oct guys should stop here (at 92%).


The following results were with a 93oct mix:

Like Run 176 from above, Run 184 was with the default TQ settings if 90%. But this time it made 360whp (~10whp more) just through running higher octane gas gas. Run 185 was with User TQ settings raised to 92%. 366whp immediately. Run 186-187 was with User TQ settings raised to 94%. Power easily climbed to 378-379whp. 93oct guys should stop here at 94%.


Next, I added in 4 gallons of 104oct, bringing average octane up to 98oct:

With the increased octane level, I bumped User TQ to 97%. Only got to do one run because the wheelspeed sensor on the Dynojet broke. And even that run was incomplete (sensor died before the run was complete) It made 388whp. For comparison is the 93oct run with User TQ set to 94%. With User TQ set to 100%, it would have made 400whp. All this on the baseline v2.0.2. Through just User TQ adjustments. Pretty neat, huh?

And yes, we did limit low end torque/boost to 360-370lbft level. We did this just to rule out ANY possibility of people through misfire codes when running poor gas and/or lugging their engine around at 2000rpm in a tall gear at full boost. We'll bring it back with v2.0.3 (as well as another neat feature or two ) So there you have it, 350-375whp on pump gas without having to assume the risks and compromises of running catless or the hassle of mixing race fuels.

I'll also post up datalogs that were taken during the above dyno results later tonight when I get some free time.

The 6AT version of the v2.0.2 map will be up later tonight.

Note: These results were all from our shop car. It is not a ringer or a "factory freak". It has 25,000 hard miles on it. It makes no more or less power than any other similarly modified 335. Rear tire pressure was set to 40psi. The only mods to it are our cat-back exhaust and cone air filters replacing the factory airbox. The factory airbox will start to become an significant inlet restriction at 355-365whp. So don't expect to make 400whp at 100% with it We'll have a basic, inexpensive intake kit ready for sale in January.

Also, please note that these results were with the factory downpipes, factory IC, factory bypass valves, etc,. So this set-up is "emissions friendly" in that it passes the tailpipe sniff test. Full cat-less cars will not pass this test. They will also smell and sound horribly. And can even fart flames during high-rpm shifts (which is actually kind of cool). In other words, the test car represents a mildly modified, hassle-free, compromise-free car that wont make you cross your fingers and pray when a police officer is following you

Cheers,
shiv

Haha ... Nice comparisons ... Good job guys !!!

Shiv, since you wont reply to PM's. Where is the V2 harness for Order ID : 10992000? Its been two months now, just wondering what the status is

Have you tried calling them or emailing Dustin?

Are these Vishnu dynos with hood up or down?
