Nice review.

In GIAC I trust.

This thread should just be taken as is. The guy likes GIAC more than his Procede. Good for him.

Great gains OP!

+1, specially when he explained the reasoning for his decision that do make sense based on his daily drive requirements and expectations.

Amazes me how some members on this forum get nasty towards some one who took time to provide his feedback and experience. Really helps to "promote" for others to post in Turbo / FI Engine and 335i -335d Tuning / Drivetrain / Exhaust Modifications their experience and point of view if they decide on GIAC, CP-e, DINAN, JB or some other tunes vs Procede....

If you ask me, by looking at the Dynos the PROcede power curves are indeed smoother than the GIAC.

You expect anything different on e90post? I sure don't and never will.

I also thought the OP did a great job posting his results and opinions on his decision. Great data/info for the forum.

I highly doubt he is getting a kickback from GIAC or that he is trying to rip on the procede or any other tunes... you in the other hand are terrorizing this thread with 6 posts already... so please please get off shiv's D, be glad that he posted dyno charts and let him express his opinion

Haha what? A little defensive for nobody attacking anyone let alone attacking you..this is a forum what do you mean 'nobody asked you'??

Anyways..I would love if the OP tried the new autotune out and then let us know what he thinks..that'd be great for the consumer

I would say this is an example of how some companies tell customers to adapt to their products instead of making their products in accordance to customer's needs.

The N54 was all about a flat torque curve from low to high RPM. A good tuner should keep that same flat curve just at a higher level on the chart.

Just my opinion...

Thanks for the dyno chart, OP.
Any reason why the Procede comes down after 4500 rpm? It holds strong until that point, and then the lbs tq goes lower than the GIAC. Same thing from when the sniffer starts reading at 2k rpm, it's lower until 2500 rpm.
Shiv, was this what you fixed in the last few maps?

If I remember correctly it's due to the older map not having the power adjusted for the whole band which is not the case in the newer maps.

If I need to go to the dealer in an emergency....Flash will CYA ..Bottom line.

If someone looks in the E box, they will find your tune! Unless its a flash.

I would sacrifice say 2-3lbs of boost for that piece of mind. ( I dont track my car)

say if I could only push 14-15psi with GIAC instead of the 17,18,19 with JB3 or procede and a clean E box than sign me up. JB3 has been performing outstandingly with 2.0 7/4 update. Smoothness is adjustable now with pedal mapping, throttle adjustments, and lag fix adjustments as well.

Plugging and unplugging your DME risks bending or breaking pins, loosening wires, wearing away the connectors... flashes definitely have a value set not offered by piggybacks but also add an inconvenience of having to reflash after updates... Also, harnesses are a link in the chain of data transmission that can fail. The best software, installer, and driver can all get together and if your harness has a short then your car will stumble, code, and in some cases not start at all. I notice that when I take my JB3 out and start my car it seems to crank a bit faster and idle very smoothly. I took some time to make sure that all my connectors were clean and shiny before my reinstall and now I cant tell the difference anymore.

I say, if you are clumsy or heavy handed or just have bad luck with electronics than a flash tune is appealing for you.

If you like to work on your car a little, the install and removal is very manageable for a piggyback like procede...

[BobS]

Wow some good and bad feedback....

I can drive, drivability is something i value, the GIAC gives me the same feeling as the stock powerband but just much stronger. Go for a ride in a GIAC car and you will see what i mean.

I realize if you don't hit the gas real hard the wheels won't spin (Duh).

I've driven a car with both tunes, how many people on here that are responding to this thread have?

I'm just trying to give a opinion of my experience....people need to relax.

Like i said, the procede is a great product that produces awesome power, the other factors like install and the risk of messing with the DME turned me away. Simple as that.

GIAC does not throw codes, none, never - no need for BT scanner.

Can you take GIAC into dealer and them not find out???? or does it have to be removed for warranty purposes??

You always run a risk with every tune, if its just routine maintenance you should be fine. If its a big warranty failure like turbo's, wastegate, fuel pump, etc. you should flash the car back to stock. BMW can find it if they look for it.

Once the flash loader comes out you can flash it to a "stock like" map and this will help while taking the car in for maintenance. I'm getting the flashloader as soon as I get a chance to schedule another visit to AWE. From what they told me, it is available.

The stock like map is just that - not stock, so if they can find the regular flash, the stock like flash will be just as apparent except when they drive it, it will feel like stock. As for finding it - none of the normal dealer stuff can tell the difference - I am sure if BMW is suspicious they will find it by analyzing the DME, but they are not going to do that unless they are suspicious and you are claiming an engine or trans or something. I just had mine over written when they redid the software with the fuel pump replacement and my tech said he couldn't tell it was flashed, of course it had no power as it was in limp, so a test drive wouldn't tip anyone off either. Always best to remove it if your worried, but after putting a piggyback in and out a few times, it is really easy to tell you have been in the ECU box no matter how careful you are, so that to me is much more risky if your worried about signs of tampering!

How long has the flashloader been available?

I'm not sure, I just inquired about it and they said it was available.

[SennaZ]

According to GIAC, it's available now:

It's been available for years for other vehicles, just not for E9x's. I was at my dealer 3 days ago to get reflashed and hoping I could get the switcher at the same time, but GIAC is still hedging on it, so don't get your hopes up yet!

My mistake, thanks for the clarification.
