yeah, i did the same just to rule out if my dv's were leaking... i would hit ~15psi on the previous maps with default settings. so i reloaded the 4-22 and same thing...pretty low boost. i dont know if its because the weather is 5* cooler if that even is enough to affect it enough. but at 75% it shines and accelerates quicker than when i had the 1/05maps and catless dp's with intake. ran a friend and i actually pulled ahead a little, previously we were dead even. so far im really happy with the new batch

so 75% seems to be working well for you guys? I have stage 1 with a riss racing intake.

You don't always need more boost to have more power... Timing and duration of boost in the curve are also important. The JB3 is a good example in that it gets a lot of power by riding the knock sensor with a little less boost.

I think these maps have less peak boost but a lot more boost down low and throughout the rpm range than the 2-19 maps. I do agree that the CANbus beta is a beast. Maybe when we have ignition control we will be able to see the difference though I don't know that it is wise to keep pushing much further...

[maui86]

for me, yes... but when the temps go back up to the 70's and 80's i'll see how things roll. with normal conditions here, temp and gas seems to limit my car to ~14psi peak before performance starts to come sluggish and very inconsistent. with some maps in the past, i've had to go lower than default settings, so dont hesitate to try dropping to 60% for starters if you're using stage1 and work from there

totally agree with you on that. that is why when i started to play with the user tq i started from the low end then worked my way up. im not attached to any particular boost number, just my car was slower and boost seemed lower than normal so i found the sweet spot is ~13.5-14psi peak. and before i used to see upwards of 16psi(via procede logs) when i first give it full throttle. now i see ~14peak...its lovely to see how controlled the boost is now. im excited to see what we have in store next.

I think if u feel these map's are a little 2 strong for your liking it is best to drop the UT .
I just came back from a couple runs and it is more powerful than 2-19 maps, but I feel it boosts bit more. I was getting 16-16.5 psi consistently, with stg.3. So I may drop the UT a little bit.

Nonetheless a really strong map , with tons of midrange pull.

I tried Stage I can bus map on NON can Bus REV I and for the moment it seems very consistent and way more powerful respect to my previous stage 0 non DD @90% ut.

More tests will follow with BT and Procede reader crossed datalogs.

Bye.

[gian335]

so your trying the new 4-22 canbus maps, with a rev 1? I think your the first to every try that out. good luck

Do you have to run a firmware update or just upload a new map for REV1 ??

Yes I am... and I'm not so scared.

A/F are better than every other map, boost is on the same levels and I
have BT for code cleaning.

Only thing I'm missing is a more refined management of timing curve... but hundred of JB3 users are in a way less favorable condition than me.

P.S. I also updated firmware to version 108beta.

Thanks for the info, I won't be completely catless since I'm not planning to get catless DP anytime soon, but planning to do catless MP, still safe to run Stage 2 correct?

Probably not. Again, Stage 2 is for completely catless.

It's just a guide. You are just running slightly higher boost. You won't really know if you are adding power or decreasing power unless you dyno, have a good butt dyno, or a car you race against that has remained static to do a comparison. Highly recommended for everyone to have a boost gauge.

Once I do catted DP's with magnaflow race cats, and an FMIC with my current catback and Intake, you can bet I will give Stage 3 a try.

From what I have gathered from Shiv's comments you could do the same thing by raising the UT value, so stage 1.5 would be running stage one at 75% instead of 70%. Or you could load the stage 2 map and drop the UT on that from 80 to 75% and be at 1.5.

Shiv can/please correct me if I'm wrong. I have not heard Shiv say that these new map stages actually have any different boost curve/table, or any other table between them.

There is some flexibility with those requirements of course. Just don't use a map that is too aggressive for your mods.

[Slidewayz]

Yeah, I would like to know if I should step down from Stage 2 or step up from Stage 1; both with current mods (DCI, catless DPs) and next mod (FMIC).

The cruddy California gas is a factor too...

Auto-tuning, FTW!

[creaminz]

Oh well, I will stick to Stage 1 then, and bump it up to 75~80% once RR MP & Bastuck is in place. Honestly I have no complaints at all with CANbus Stage 1 map. Fast enough for me

You runing 91 or 93 oct??? I myself run Stage 2 with only DCIs on 93 octane and I have a 10whp gain (dyno tested). Then again, I was also running REV II Beta CANbus without the CANbus wire update without any problems as well...

Find a dyno shop that charges 50 - 75 bucks and try Stage 1, Stage 2 and Stage 1.5 (Stage 1 + 75 UT). I think this is your best bet.

I am going to try Stage 1 and Stage 2 versus the old BETA CANbus sometime this week. I will keep everyone posted.

Are there high-flow cats available for the 335i? Have there been dynos to prove they flow better than stock? It would be very good news indeed if so.

[Gen_E92]

The new map with CANbus is definitely smoother compared to the 2-19 map...might have slightly more power and top end feels abit stronger...my frd and i both noticed the exhaust got louder on both of our cars. Huge props to Shiv for CANbus, I can't wait for the next map already

[Kelvin1000]

To me, the difference in these maps is quite significant versus the 2-19 maps. A new generation with a lot more torque down low and all across the curve. I don't get how some people don't feel an immediate difference...

[Kbueno]

I can't really tell a big difference....maybe some more in the higher RPM. Boost is more conservative...which is fine with me. The changeover at 4k is improved after adaptation, although there is a slight surge under certain conditions (I think my car is just boost sensitive??) Wanna try the race map, but I don't like the limps people are posting about. Definitely need a MAP1=MAP2 so I can fine tune a low and high boost setting. I will say this..these new canbus maps seem to have more control over boost...nice stable boost levels.

[Kelvin1000]

Are you comparing these new maps to the 2-19 maps or the BETA CANbus?

91 oct crappy CA gas Only DCI and you r running Stage II ? hmmm...I will Dyno it once I install everything.
