Been upgraded today from P 25.X to the latest ISTA/P 35.4 per my request, nothing wrong with the car btw. Was very nervous to be disappointed with the new upgrade, as I was avoiding all possible dealer visits during last 2.5 years of my car's ownership.

As I picked her up, I was pleasantly surprised. The latest software is much improved over 25.x that I had. Things that I've noticed on my way back home, on a otherwise stock car.

1) Louder exhaust, during drive and idle.
2) Smother boost to vacuum transitions.
3) No more lurching forward from the dead stop, after light throttle application.
4) Smoother and faster throttle response in the low rpm (before and after 2k).
5) Smoothed out shifts on AT in DS.

FYI, I've never had any westgate rattling or other issues with the car and my DME version is MSD80.

Bottom line, feels much better then 25.x. So for all the dinosaurs out there, don't be nervous and go upgrade.

Now on to GIAC dealer tomorrow.

any idea how to check what the current version of the car is through idrive or something?

Nope, all stock but the tune. Not present during the update.

Im a very early production dinosaur and there are lots of post on this but Im not sure what in a nut shell are the pros and cons.

If I stay stock is there a benefit

If I do a simple JB+ or JB3, intake maybe exhaust is there a benefit.

I Remember guys not liking the update

Is this something a dino like myself should consider.

I did have a HPFP recently installed.

I have been updated too this week to the latest version. My car never been updated before since 2006.

Like OP i notice alot of difference , all in a positive way.

Car is much louder around idle due to different wastegate operation.

Much more responsive in the lower rpm's.

For now i only noticed the silver background in the I drive screen , so far no other differences.

The main reason I did it, is to allow my car run GIAC. Simply because they don't flash cars with very old progman versions. Their new REV2 Stage 1 designed on newer ISTA/P's. Since I did it I don't regret one bit, it's all good.

Just curious... I'd like to have this done to my car just to be on the "latest greatest". According to Shiv, it's fine to do with the v3's.

Thanks!

Nick

Sorry, no iDrive. After being with piggybacks for 2 years, I think it should be mandatory for piggy users to upgrade their cars in order to run on the tuner level. Both Terry and Shiv is always up to date and usually designing their newer maps based on the latest software releases. I was in denial all this time to upgrade cause of the 29.2 crap, but now I'm glad that I've waited a little longer for 35.x.

yeah apparently 25.x was full of bugs and missing tables . I probably have 27.x version and GIAC could flash me without issues with my file.

[e.n335]

I got my ECU flashed ( Daehler / Evotech / Noelle ) on top of Progman 34.x. No issues at all, car runs great.

Was wondering about this.

Still rocking pre29.2 and have chosen NOT to be upgraded for most of the 2+ yrs I've owned the car because everything has run great... until the PROcede's recent CANbus features. I now get some boost oscillation and just some weird cold start behavior from the car. No codes except from the new O2 sim issues (cat inefficiency codes).

I read in another thread about some possible incompatibility with older versions and the PROcede's CANbus based features and was wondering if getting upgraded would smooth things out.

I was upgraded to 2.35.4 this week and lost approx 2 psi of boost and no idea why.

Agree exhaust has a bit deeper tone on other posts. Re-calibrated my rixtstr boost gauge and car was fully warmed up. Peak is 6.6 on WOT runs, should be 8, or 8.8 on stock car. It's been cold in Chicago, but I can't ever recall why boost would run lower than max even when it is cold out.

[shifterboy45]

remember the car will do its best to give to the best performance possible, based on the existing conditions..

did you disengage DTC/DSC?

i know the current version of the software is spunkier than the 32.1 that my car was delivered with. Im currently at 2.34.0, Which was a welcome change..

[cali_guy]

I got updated to 35.4 for some idrive updates and love it.

[Sevak - Deleted User]

Hi my car is build 2006/09 I dont think they have update the car since it was new.
My car is tuned with a flash I also run catless DP with 02 sims.
If I upgrade to the latest version 35.4 will I get any problems with my catless DP or 02 sims?

i have a late 06 build...

I have answered this many times already. Go see your dealer, hand him your car key to scan, he'll tell you witch version you have and if there is an update available.

If you have BMS sims, I would ask Terry.

The car boosts much lower in cold weather... this is because the cold air is more dense, therefore the ecu knows this and lowers boost to maintain the same engine output... it also runs up to 11psi in super hot weather when the air charge becomes much LESS dense.

8psi is only the magic number in 70 degree ideal weather.

For example, if it is 40F outside, stock cars boost under 7psi...

I have the 2009 i-drive. The new update fixed alot of bugs. I had a 11/08 build 2009 E92.

I know people who lost 0.5 MPH of trap speeds systematically when "upgrading" from early versions into 33 and 34 family. Is 35.4 faster than 33? I don't have any info about it.

I dunno, didn't measure anything. What I do know is the latest "feels" much better then my famous pre 29.2 (25.0), that's all I care. Drove with it for 1 day before flashing with GIAC.
