Helix Chip tuner

Hello room

I just bought a 335i e92 and I cant wait to pick it up. I need some advice. I bought a used Helix performance chip ($250). How good is it? How do I install it? How do I change settings on it. I don't know if I did the right thing by buying it.



Thank you every one. I found this at their website







Legendary chip tuner GIAC now bring their technology to BMW with flash-to-DME software.

Newly Released GIAC Software for BMW 135, 335, and 535 Applications

Stage 1 GIAC performance software is now available for BMW 135, 335, 535 applications. For optimum performance the software must be coupled with exhaust.

* 55 wheel HP and 55 ft lbs of wheel torque gain over stock (dyno plot
link). Gains are estimated at 60 HP and 60 ft lbs of torque at the crank.
* OBD2 port flash installation
* Enhanced throttle reaction
* Smooth power transitions
* Removed speed limiter
* Higher rev limiter, 7200 RPMs
Switching options may be available in the coming months.

Dynamometer test results are included here using a test vehicle courtesy of
AE Performance. The graph plots three runs for a 2008 E92 335i 6MT with an
AE Performance cat-back exhaust and dual cone intake on 91-octane fuel. The
second run is the baseline run with stock DME programming. The first and
third runs are performance runs with GIAC Stage 1 programming.


Baseline testing for stage 2+ has also begun with the use of a 2008 135i
from European Auto Source. Each run was conducted using an EAS dual cone
intake, EAS upgraded downpipes and an Evolution Racewerks front mounted
intercooler. The first run is our stage 1 baseline and was performed with a
GIAC stage 1 flash. The second run was performed with stock DME
programming. Dyno tests have shown impressive gains for the added hardware
setup with just the stage 1 flash and we look forward to even more.
Additional information regarding stage 2/2+ will be released as it becomes
available.

Helix is NOT GIAC.

That would be your first step in the equation. I wasn't even aware that helix made a tune. Good luck with that.

helix made a tune a while back around procede v2/v1 times

I believe they wound down the project after bmw started to move against tuning

Helix has their own piggy-back tune called Attache which is still being sold.

But, Helix is also a GIAC distributor. (reflash so no hardware)

To OP: Sounds like you are confusing the two... search and you will find info on both. GIAC is more popular and widely accepted currently, though that does not necessarily mean that Attache is not a great product and will work for you, if that is what you purchased.

We do still sell the Attache, although we have not developed it as far as Shiv and others have developed theirs. We do sell GIAC's direct-flash-to-DME software which is excellent.
