[e.n335]

Hi guys,

I did a lot of data logging during the last 3 days. What I found out surprised me in a positive way ( however, may not be new for some of you ):

I am driving 85 - 90% not under boost. When I drive under boost, I don't exceed the factory 11.5 psi by 75% of the time.

This means that I am driving with 13.5 psi around 3.5% of my overall driving time, only about 2 psi more than the factory specifications which we all know that they are very conservative.

This is with the v1.47 map, I never had any problems, CEL's, limp conditions, etc.

Hey, this car with the PROcede will last forever when you service and treat the engine well. I am quite happy about the results and just wanted to share with you what I saw in the datalogs.

Cheers
Eugen

Eugen does the BMW have an average speed Counter somewhere in the dash, if so would be interesting to see your average speed and mileage..

(not vastly accurate I know, but fun all the same)

I thought that stock boost was 8psi though, not 11.5? I am willing to bet that I probably drive my car 90% of the time out of boost also.

[BzzzBom]

I thought that stock max boost was about 9 psi and could increase 2-2.5 psi to adjust for altitude whcih would bring the upper limit to 11-11.5.

you give ppl like me hope...As in problems and all these stuff makes u quesy but the performance cannot be discounted. Gonna get it installed soon...

[e.n335]

The turbo's are specified from BMW to do their job up to 0.8 bar ( 11.5 psi ). PROcede v1.47 makes boost up to 13.5 psi ( in my car ). So we have a difference of 2 psi. Even when the stock turbos will provide the 11.5 psi only @ altitude ( which I don't know ), they have to be reliable for this pressure in the case customers live on high altitudes.

Shiv said already we will not see higher boost with v2 and those little boost spikes happening when you stomp on the pedal will disappear completely. So v2 will be better related to boost than v1 already is, and v1 is already very good.

In addition I will do something good for my turbos and install the Spearco FMIC which reduces pressure drop about 0.5 psi in worst case, most likely 0.7 - 0.8 psi. This means that the turbos in fact have to provide 1.2 - 1.5 psi over stock specification. In this case I feel this is really nothing when it comes to reliability.

I posted this thread that you see the impacts of the PROcede. Of course, there are other impacts as well, e.g. the amount of fuel injected into the cylinders or EGT's. But when I look at the overall big picture it seems to me that the PROcede is a very reliable tune, when you use the car as your daily driver.

Raced cars will have more impacts but that is true for tuned and stock engines as well.

Cheers

this is a tad refreshing considering all the other "I get limp mode only 2-3 times a week" posts.

Even jon@themshop got rid of his procede because of persistent limp mode problems, even on the LBT maps.(so i heard)

Every 335i has this counter but in fact it does not say that much. The numbers I posted here are for spirited driving out of town, but not beating the car. I drive a lot in town as well so my average speed counter will be pretty low. Thats why I logged 3 days of spirited driving, having fun with the car. When you are cruising for hundrets of miles or drive downtown the car will not be on boost at all.

Which I don't understand. I use the standard v1.47 map, high quality gas, broke in the engine fairly good, did an oil change after breaking-in and have no issues at all.

The only additional things I did are that I soldered the harness contacts at the PROcede side and tested them before the installation. The contacts in the ECU box are covered by a shrink tube, not a tape. Nothing more.

maybe we need a procede limp mode poll

[Panoz]

I think that procede itsself is not responsible for getting the car into limp-mode. You can also get the car (in stock form) to this state under certain driving behaviour.

sorry, but if you install a procede, and get limp mode, you can be 99% sure that it was the PROcede... ok, maybe 98% sure

unless ofcourse you f#$#%# up the wiring, then its your own fault

The limp mode issue is NOT the main reason why I removed and sold PROcede. I had the Turbo Tuner first, then the PROcede with v1.45. The PROcede was about half a second faster than the TT on the 1/4 mile and I really loved the torque output . When I removed the PROcede thats then Shiv came out with the v1.47 but couldn't really turn back because I sold it to a board member in Canada. He uploaded v1.47 and he told me he's really happy with it.

[e.n335]

Shiv mentioned, he sold 500+ PROcedes. It is normal that ppl are posting problems, not when everything is fine. I think here are not more than 20 ppl posting problems with the PROcede and we don't know if they have additional mod's like taped diverter valves, BOV's, leaking Boost gauge hoses, etc.

It is also known that maps up to v1.47 can cause a limp mode even while cruising. If I had a problem I would first update to v1.47 and then check the other mod's when the problem persists. It will not be wrong to reset the PROcede after loading a new map. Shiv says it's not needed but I am curious when this new loaded map will get active. Instead of asking how this works in detail I just reset the PROcede.

sorry, a local member told me he had a phone conversation where you mentioned your PROcede was giving you limp mode issues several times a week... didnt mean to spread false info, let me know if that isnt true

No problem. It was probably a misunderstanding. PM sent.

[e.n335]

Just one more additional information. I installed the PROcede with the ignition on by my fault, having the driver side door open. This caused a lot of problems and the car was no more drivable.

To be sure that the PROcede can work you should have:

- A 335i
- An ECU with no errors stored in it
- A correct installed and working harness
- A PROcede with v1.47 loaded ( and resetted - Shiv pls. don't beat me for this )
- Correct installed or no other mod's
- Good gas

If this is given the PROcede works perfect.

Cheers
Eugen

On top of that there are altitude adjustments that also pass through on the procede. So, if you're running 13.5psi in the midrange and 12.5psi up top at close to sea level, you are making 6.5-7.5psi more than stock. That is a good thing!

I can't believe this posting. I don't want to be rude as well but please do your homework and search the internet to find that BMW states that the turbo's are working and specified for up to 0.8 bar ( 11.5 psi ). I did not talk about any rev ranges, did I ? I trust BMW publications more than I trust you even if you tell me different things several times.

I am disgusted about those Terry clones popping up since he is banned.

Don't you think that Shiv is probably one of the most experienced and most knowledgeable about the 335i, especially in regards to the turbo boost, maps, F/A ratio, the ECU, etc.??? Well, the answer is yes, and he's mentioned over-and-over the exact stock and PROcede boost values.

Nothing against what you've been doing, but exactly how long have you been playing around with your 335i? What kind of technical knowledge do you have in regards to the inner-workings of the 335i, its ECU, turbo boost, maps, F/A ratio, etc.? Shiv's been doing this since day 1...Sept. 1, 2006 (the 1st day the 335i was available on dealer lots) when he took delivery of his own 335i and began his R&D on the XEDE (and then PROcede) specifically adapting it for the 335i. I believe Shiv has said that a stock 335i's turbo boost goes up to 11.5psi, and a PROcede 335i's turbo boost goes 2-3 psi higher.

In reading your posts re: the intercooler, and now this, I've noticed a trend. You tend to put forth your opinions or guesses as fact when it's clear to others that you are mistaken. To avoid further confusion might I suggest using the phrases IMHO or AFAIK proceeding these statements?

AFAIK you should be able to google for "bmw 335i 0.8 bar" IMHO

Ok...maybe we're all wrong. I found this (although this info was for PROcede v1.2, and I believe v1.47 is running just a bit higher boost???)...

http://www.e90post.com/forums/showth...cede+boost+psi

Apparently, a stock 335i runs ~ 8psi (like you said) but it may spike up to ~ 10psi; a PROcede 335i runs ~ 10-12psi and may spike up to ~ 14psi. This is one of the changes for v2.0...to eliminate the spikes for a more consistent boost range of 12-14psi. Sorry for the confusion.

[e.n335]

Did a quick search. You will find many other publications, also from BMW. This is one example for a qualified statement.

Eurotuner magazine article extract:
...

The Man From MunichWe had a chance to speak to the Coupe's Powertrain Project Manager, Udo Lindner, with a view to understanding the car's tuning potential.
...
So what's under the 335i's hood? "We have two Mitsubishi turbos running at 0.6bar (8.8psi). These can boost to 0.8bar to compensate for altitude using the two electronically-controlled wastegates," Udo explained.

...

0.8 bar are 11.6 psi.

13.5 psi PROcede - 11.6 psi = 1.9 psi over specification. Hope that helps.
