Hi,

I've been quite busy and haven't been here for more than a year. My car was in a garage all this time...

I was trying to cath up with the news but it is absolutely impossible.... Everything changes so quickly, not to talk about more than a year of absence here...

My car is '07 335i MT (details in the signature), Vishnu Rev2, V4 (don't remember which maps, but they are more than 1 year old).
I also have RB turbos, but they are not installed yet.

Can you please tell me what should I do to run RB turbos? I saw that there was a new version of Vishnu (Rev3). Can I still run Rev2? Maybe there is some kind of upgrade option?
Which maps should I use before and after I install the RB turbos?

If there was a thread with all the news. But there isn't.
Can someone please sum up what has changed during this year? Autotuning, etc.

Thank you in advance.

Can't respond to all the specific questions regarding the PROcede (updates/firmware version/compatability with RB turbos), but the big recent development was E85 Maps

Check it out, it might satisfy your power needs & let you avoid having the RBs installed

1. You can send in your rev 2 to be upgraded to rev "2.5" for around $50. And with that you can run the latest and greatest maps. Or a bit more for the full rev 3 upgrade (no-lift-shift, 2-step launch control, etc).

2. There are dedicated "upgraded turbo" maps. You'd just load that up and be good to go

Use COBB ATR.

Welcome back!

If you want to keep using the Procede, I would recommend you get it upgraded to Rev 2.5 or Rev3.

Otherwise Cobb has seen some good development lately, especially for 6MT RB cars!

[Wedge1967]

For the guys trying to give you the COBB, it's a $$$ option if you swing that way. JP is right, give Robert a call and get your Rev. 2 upgraded to a Rev. 2.5 so you can run the latest maps. At this point in the game, I don't think anyone is putting down as much RWHP as the Procede with e85 50/50. Although everyone is in the game, Shiv has been a mad man for the past year with development. I think you'll find that going from a Rev. 2 to a Rev. 2.5 with the new maps will make you feel like a kid in a candy store again. A lot more torque and a lot more RWHP.

e85 is the name of the game now a days... everyone has it now though... if you feel comfortable tuning your own car COBB may be the way to go but if you rather just plug and play, PROcede has shown the best numbers for OTS maps so far.

[themyst]

Piggybacks cant extract maximum performance out of RBs due to fueling limitations. You will see yourself lean out pretty quickly at boost levels higher than around 18 psi unless you're content running a ton of meth as a band-aid. I run a JB4 which uses the same approach to fuel (o2 bias / fuel pressure) as the Procede does. Definitely upgrade to rev 2.5 or 3 if you are installing RBs.

Cobb ATR is the best solution though, bar none.

[edo]

Thanks for your replies, guys!
Wow, when I was last time here, Cobb was making much less power than Procede and JB.

Isn't E85 harmful for our fuel system? At least it was stated so ~1 year ago.

How much is upgrading for Rev3?

There is still debate circulating whether e85 is bad for the fuel system or not. Some have said they spoke to knowledgable people who say the filters on the injectors when heated to 100 centigrade will begin to fail with e85. A lot of people choose to ignore the cons, if there are any.

Simple answer, e85 is still being explored, it's not necessarily a sure thing at this point.

is this true for dinan flash/jb4 stack

[Tranic335i]

Cobb ATR/protune is hands down best option right now. You can buy a used Cobb AP for $650 around here

I don't really know what Dinan targets for timing/AFR so I can't say if it's beneficial. The beauty of stacking Cobb is there are numerous OTS maps available to cater to various needs, and ATR/ATP gets it all over the top.

[enrita]

Cobb is the best tune out right now.

[edo]

Hmmm... I'll do some reading about the Cobb.
But switching to Cobb will be pricey... Upgrading to Rev2.5 or Rev3 would be cheaper, right?
What I liked about Vishnu was it's simplicity. Plug in, upload autotune maps and forget about it. Is Cobb similar?

[JamesM3M5]

Procede upgrade will be much cheaper. Both offer easy map changes, but the Procede has on-the-fly map switching and direct meth support. The Procede PWM is the most complete failsafe for meth as well. Piggybacks also offer gauge hijacking.

There are people from all sides say one tune is "the best", but the only way to verify is to test for yourself. Others who have tested multiple tunes with varying levels of modification are here offering good insight as well.

[boostaholic786]

I'm running the JB4 15ohm mode with RB's and custom maps from terry but fueling is still an issue as the JB4 can not change what the DME thinks. I think DINAN will help you out but for stacking tunes, Cobb and JB4 (You get all the cool featurs with the JB4

[boostaholic786]

Look into Proceed's new single turbo set up also FREAKING SICK

[SIKH335]

I really dont get all this Cobb is the best tune out right now talk. Can some one help me out here what has Cobb achieved?????? From what I recall nothing. My car running stock turbos and Procede is the world record holder for the 335 N54(11.35 at 122.8. 444whp 508ftlbs). Not to mention that my car runs awesome at 580+WHP with the single turbo and Procede on my 6at (650whp MT). Not to hurt anyone's feelings but show me some numbers.

PS Myst I thought your car didn't like Cobb.

[edo]

Does anyone know how much is upgrading form Rev2 to Rev3? To Rev2.5 it's 50 USD someone wrote here.

New single turbo kits were released while I was away (Vishnu, HPF) and I have those new RB turbos in my trunk waiting to be installed.
Is there a valid reason to consider selling RBs and getting single turbo kit? Single turbo kit makes more power (how much more?), but is more expensive (+shipping to Europe). And I would have to wait another year till I can joy of the new power (I don't drive 335i during winter and it would take a lot of time till the new single turbo kit arrives and gets installed...).

+1
I checked the 60-130 mph list, dyno chart thread and cars with Cobb are nowhere near the top of the lists... Except Cobb/Jb4 combo which is weird (imo) and pricey for me to switch to.

[Laguna Seca Blue]

You can upgrade to Rev 2.5 for US$50, but I'm fairly certain you need to replace your current unit if you want Rev 3. From what I understand, the only real-life feature that you'll be missing out on with the older unit is native USB connectively for upgrading maps/data-logging.

I'm surprised that one of the more experienced members on this forum is saying "tune X is the best," without giving a reason. Sounds like a recipe for war

As far as I'm aware, the Procede's Boost Control feature is unmatched and AFR targeting is spot on. Given that the Procede is able to support fueling for the single turbo, I doubt a set of upgraded twins is going to cause much of a problem. However, I'm new here, and if anyone can provide an explanation of why a Procede/RB turbos car would struggle at higher boost levels, i'd be interested.

Cobb obviously makes a great product, but for people to try and convince you to ditch your PROcede that has been proven to be just as good (if not superior) to the competition, seems a little odd.

Edo, do you have an automatic or a manual? The Vishnu single-turbo AT is putting out around 570whp and the Manual 650whp. Search Shiv's recent threads, there's a lot of good info there.
