Absolutely, in fact - it embraces them.

On MT cars. My AT shifts normally at ~6900RPM. Speed limiter removed.

Very interested in getting the flash, just wondering if it is possible to erase tuning codes for warranty purposes.

Any information would be appreciated!

As written previously, the GIAC flash doesn't trigger any tuning codes (which does not necessarily mean it's invisible), therefore you don't need to erase any. But there are tons of posts on this subject, just do a little searching.

And even if you do just get a BT tool...

The more I test the GIAC Stage 1, the more impressed I am.

I did a little "track testing" in a corporate parking lot at 5:00am and it is a world of difference. In a straight line, the differences between the Piggybacks and the Flash are less evident after both have reached wide open throttle.

However, during normal driving and especially during spirited track driving with turns where you have to be constantly applying various degrees of throttle and you have to come on and off power, the differences are huge. The piggybacks tend to have less control which can cause either too much or too little power in the turns (frustrating or scarry). With the flash, I have complete and total control. This thing makes me not envy the naturally aspirated M3s which have instant and controllable power.

The other big difference that I already spoke about is the lack of bog when shifting. The solutions offered by the JB3 and the Procede are decent when they work, but I find that they are hit or miss (at least for me)... I have yet to miss the perfect shift with the GIAC.

As I said before, I have no affiliations and paid full price, so I say this just to give back to the forum community and to do you guys a favor:

Piggybacks are great alternatives and have served many of us well. You can't beat the JB3's price for the power, features and support. But if you are willing to live with the lack of flexibility inherent to the flashes and can spend a little more money, then I highly recommend that you skip all the tunes that I have been through and go straight to the GIAC.

The flash is in another league. It is just that remarkable and I can wait for Stage 2!!!

More logs to follow...

hey Kevlin, definitely do some 2nd/3rd/4th gear boost/throttle/timing logs if possible. I think everyone is verrrry curious what these look like!

GIAC does reminds of NA motor while piggys of FI. By skipping the "other" tunes they wouldn't able to compare and feel the difference. (jk applied)

Don't worry, the V-tech still kicks in yo!!!

Well said...I totally agree. My custom tune is so smooth, powerful and predictable.

You need to team up with someone that has the ProC v4 for comparison.

once it's final, that is. I've felt both and i think you flash guys will be very surprised. Definitely something you need to feel first hand.

Either way, it's nice there are a few good options now adays.

[Kelvin1000]

Boost targeting sounds interesting in Procede V4 but the timing tables in the Flash are there by design. There is not a system trying to actively trick them one way or another.

I can't explain it but the car just feels like its not struggling at all to put out all the power. It all seems so smooth, efficient and effortless...

LOVE IT! Cant wait to get my flash.

[I335]

I agree with everything Kelvin is reporting. I've had my GIAC stage 1 tune for about a month now and it's just fantastic. I really don't think I'll be going for a stage 2 because I'm so satisfied with stage 1 and I really don't see being able to use the extra power often enough and stage 1 is plenty powerful enough for me. The tune is so smooth it feels totally like an OEM BMW - just with a lot more power. I think my car actually runs smoother than it did with the factory software in all situations.

Kelvin what peak/sustained/redline boost you're seeing in what temps? (With BT if possible) Curious since you have the S1 and bolt-ons. Thanks!

[Kelvin1000]

The wife and kids have kept me away from testing the past couple of days but there is a midnight test session coming soon...

I believe that the GIAC has Torque targets and once it hits them it stays there. Remember, it has full control of all parameters.

I feel like there is a point where the power could keep going but it holds steady instead. I guess that's what stage 2 is for...

I know that! Just wondering what your BT logs showing with mods compared to mine without.

[Dan335i]

If for any reason you have to go back to a stock flash,will the GIAC dealer flash you back to stock,then flash back the GIAC 1 for free?

[Kelvin1000]

Might have to pay labor but not for the actual Flash.

Also, if you want to upgrade to Stage 2, you only pay the difference.
