With all the talk about the "unsual" boost spikes with v2 AND Eugen getting angry at Vishnu (If you've been on this forum since the release of the 335 like I have you know what that means!!!) I think it's time to compile some numbers. Please vote only if you have V2 installed.

[e90AW335i]

Kind of a Repost.....I bumped poll that dealt with this as well......

[scalbert]

Obviously, it is obvious where I fall.

[Barat]

4 out of 5 with gauges have issues so far please keep the results coming

[Tuned335i]

I'm gonna vote after I get my gauge installed this week. And FWIW, there's no real reason to include people without gauges in this poll since they have no idea what is going on (me included). My PROcede V2 datalogs show a maximum of 15.0psi on one occasion with the stock map. I have since lowered the stock 100% settings to 95% but haven't had a chance to datalog again yet.

I agree with your Eugen comment. I was pretty surprised to see the about-face from him late last week. Anyone who follows this sub-forum knows that he's been one of, if not the most outspoken proponents of Vishnu. I don't want anyone to take this the wrong way, but if you read the tone of his posts, it's almost like someone else is using his account, or he was intoxicated when he wrote those posts. The tone and attitude you take from his recent posts a couple of days ago are just 180degrees from what he's posted in the past, and his car has no problems whatsoever...

I think the fact that the Vishnu guys took the long holiday weekend off is really frustrating some people here, like they expect 24/7 support from them. Yeah they need to address the issues raised by users, but everybody deserves a holiday. The bummer is that I don't know how they could catch up with all the crap that has been posted since Wednesday night when they logged off...

Just my observations...worth exactly what you paid for them...

LOL...Yeah!!!! And you've got the most experience trying to troubleshoot this too. Should have a hotline to Shiv...

Exactly how I felt...and that's what got me worrying. I put the no gauge choice in there just to have a feel of how many people out ot the total V2 pop are replying to the post (roughly 100 V2s shipped thus far if I'm not mistaken). Let's hope more people will chime in. I think it's an important topic, and even tough Shiv replied in another thread that 18+ psi spikes are normal (and shouldn't impact longetivity of the turbos) I still think it's a long stretch from the stock 6-7 psi boost.

how do we check boost with v2?

you need to install a boost gauge (check the DIY section)

can we check it procede data logging?

Yes you can, but it has been proven that the boost gauge and the procede software are sometimes seeing different values.

By how much?

to check for boost using procede software, do we run to redline when data logging? and in what gear?

[OpenFlash]

Any gear. But ignore the spike that gets recorded when you lift off the throttle. The only valid measurement of boost occurs when you are at full throttle when the pressure in the intercooler pipe (where you are measuring from) is roughly the same as it is in the manifold.

Wait, what happened that made eugen angry at shiv? I have been away on holiday. BTW 20+

Wow this is better than a Soap Opera!!!

[M3to335]

Jeeze.

So far so good with mine, or so I think. Its pushing 16 max right now. I havent seen any funny spikes either.

Anything is better than a soap opera, i would rather watch Richard Simmons work out.

Searched...read that gauges out of the box can be much as 10% off??? WTF?
Digital vs. analog, cheap vs. expensive. Someone enlighten me...seems you can't fully trust any gauge?

Hi,

If my tone has been that inappropriate, I am sorry for this. I am more than happy to support map development by proper testing but I can only contribute when there is somebody listening.

I take the testing very serious, even ( not only ) with different torque settings. What happened in advance of the Thanksgiving holidays is that some reported engine stutter, some engine hiccups, some about unusual boost spikes and all combinations of that. I tried to find an intermediate solution for all who experienced those issues.

I came up with the battery disconnect to force the ECU to learn from scratch. This helped in some cases. I came up with a method that the ECU learns the new tune / settings solid and quickly. I did not only write about it, I also do it everytime I change settings to get a clean baseline for my testing. Whenever I get a limp mode I connect the car to the BMW diagnostic system at the dealership, analyze the issue and let clear the error entr(y/ies). You can imagine that this is time consuming, but this is fine with me.

It was not possible for me to create torque settings providing a 11-13 psi tune without seeing spikes when I floor the pedal, getting 2 psi more boost after shifting, getting 15 psi even the torque settings limit boost to 13 psi, etc. All this happened randomly, I could not detect any reason for this. I don't talk from boost spikes lifting the pedal, these are normal and will not harm anything. Friday last week I got a quite deep and loud hoovering sound from the engine bay, lasting 3-4 seconds, disappearing when I lifted the pedal.

In addition the datalogging part of the PROcede Reader software showed different boost values compared to my electronic boost gauge. At this time V2 got out of control from my point of view. What was really needed to make progress were map changes, not additional testing. Quality, not performance.

Shiv reacted very fast. Even he did not comment on anything, he invested time on Saturday and Sunday to release newer maps for testing purposes to ensure v2.0.2 progress. Overboost is switched off at the moment. This will help to isolate remaining issues, if there would be some.

I will be on the road to test the newest map version soon and will give feedback in a couple of hours.

Cheers,
Eugen

Forgot to mention:

Not one single error entry in the steptronic control unit since I got the PROcede and the car ( 8500 miles now ).
