People were calling the GIAC tune "the most agressive tune out there."
Now, people are happy because they made so much power because their tune was boosting 19 psi to redline.
This tune is under powered. lol

It just proves that no matter what, most people will find the need to defend whatever they have and they will do it...just because.

Back 3 years ago 15-16 psi was considered really dangerous, and now 15-16 is the norm...Alot have changed in 3 years thats for sure...

I only had my car since 02/09, if I didn't see 15psi i was disappointed

This would be great. If you could just release an electronic board similar to the map switcher but with the switches being able to be toggled by electric signals, it would be all that's needed. I even thought that someone could just disassemble the switcher and hook up some electronic switcher...

Alternatively I think that everyone could install a "manual" failsafe like a LED glowing when there is no methanol flow. I wonder what would happen if running the Stage 2 Race map for let's say 5-10 seconds on 91 octane ? Would it be dangerous or would the ECU try to compensate somewhat based on the knock activity ?

Ask Enrita

If Boost is not lowered, you're into serious trouble...

The n54 platform and upgraded turbos and a need for more boost is coming, I'd hate for you to miss the boat on potential clients.

As others have previously stated, I would not put a tune that can produce the power levels that GIAC stage 2+ is operating at as a slow tune. Sure, you can produce more power out of a JB3 or a PROcede, and if that's what some of us want, they go with that option. But I think you will agree that, in the end, that is not all of the forum users, let alone all of the 335i owners.

Also, I am fairly certain GIAC will also release a flash for upgraded turbos at some point in the near future. Now that the stage 2 and mapswitching device are finished, they can look at this option as upgraded turbos will become more widespread. I'm looking forward to that myself.

I would not assume that they haven't. Speaking for myself, I have tried two other options before switching to GIAC, and I know I'm not the only one.

Not sure how that is going to work out, look forward to seeing results.

I agree.

I can confirm that I have run the stage 2+ flash (without meth, just 98 RON fuel) during two week-ends and around 25 laps (500 km) on the Nürburgring. So, not only a bit of time, but actually quite a lot, relatively speaking. No problems whatsoever, no limp mode, just consistent and amazing power.

I will spend the next week-end at that circuit again, FWIW. This time even without an additional oil cooler, as the replacement from AR design still hasn't got round to my garage - BUT instead I'll be running their upgraded radiator.

That would be of interest to me as well.

Did you do any timing logs ? If Stage 2+ works ok on 98RON, I suppose there is no problem if the methanol flow fails while on 100RON pump gas, which is what I am thinking of running at some point...

[enrita]

the Stage 2 plus has different timing tables incorporated. As soon as the knock sensor threshold gets higher more aggressive timing is used.
i remember seeing 1 degree more timing advance on meth than on pump gas at redline. Max timing i have seen was about 15.25 .

[shockin330i]

Hi guys, Just a random n00b question on flashes. I read somewhere that flash's couldn't run meth due to a fail safe issue.

Yet i see that OP runs or has run meth with this flash. Was this other source totally bogus?

[enrita]

again i repeat this... meth failsafe is needed if you run HIGH boost like 17 plus psi on stock turbos. The GIAC stage 2 race run the exakt same psi as stage 2 but uses a much more aggressive timing table.
Since the ECU is fully aware of the boost levels it can also react and pull the necessary timings if the octane level drops.

If you want your car to be a "sledge hammer" then go purchase a small block chevy and run alcohol in it. Then take that to the drag strip.

If you want a luxury "sledge hammer" then go buy a Cadilac CTS in a flavor of your choice.

All of you people who are nagging about GIAC being conservative and not delivering the highest HP/TQ number, you should be ashamed of yourselves as you apparently do not get the point of tuning european cars... Its about driveablity and consistency of performance in various conditions and road courses, not a 1/4 mile run down a flat, leveled surface...

+1..could not have said it better myself...personally I will be running GIAC Stage 1 with FMIC, catless DPs, catless exhaust and intake...my theory in doing this is to get good consistent performance and keep the turbos running low duty cycles and engine running safely ..since GIAC is torque targeting i will make good power ~370hp and probably not break 14psi..I think anything over 16psi cannot be safe for extended time and i plan to keep the car for the long haul.

thats my opinion... focusing on the suspension would yield better performance returns which i def am doing as well..but I suppose if u want u can run any amount of boost through these engines..but I would challenge u guys to run compression tests on ur engines and/or inspect the turbos after say 50K miles..u may be surprised at the results..i may be an alarmist but i choose to err on the side of caution 30-40 hp isnt worth the potential for mechanical consquences down the line..like vasillalov said..if u want a balls out drag car get a true american muscle car. These r Bimmers..they should be modded accordingly.

There are so many miles on this forum at 16psi of boost and 360-370whp that if there would be a danger, it would have shown up until now. There are only 2 documented engine failures and those people were really really pushing their cars.

If the correct supporting mods are employed like a low-pressure-drop intercooler and a free flowing exhaust, I think that the turbos are ok. I really wish the turbines would be the only risky thing...it's not very exopensive to spend $1200 + labor on installing new turbos every 60-70000 miles.

What do you consider so many miles? I have spoken to GIAC and they told me personally they know of no one who has done more than 20K miles on stage 2 w/ boost over 16psi...I am talking about 50K miles and more..I would love for someone to step up and say they have run this engine at > 16psi for 50K miles or more..i don't know of anyone..i suppose time will tell...but i can tell u there have to be some effects of that level of boost as the miles get packed on.

thats just me view point.. I have no objection to people running their cars hard..as I said for me... stage 1 w all stage 2 bolt on mods is both powerful enuff and safe for the engine/turbos..370 hp at < 14psi is perfect..if everyone else wants to roll the dice..np..maybe people are not planning to keep their cars for too long and sell it to some unsuspecting person after they put it back to stock form..

One thing to consider is that even if you have Stage 2 installed, you are not pushing 16psi all the time, if you run your car as daily driver 95% of the time your car will run at stock boost. There is also a stock mode which you can activate and prevent the high boost.

As for running the turbos at >16psi at some racing events, I don't think there is a big problem. I am not skilled at reading a compressor map but I did look at our turbo's maps (there is a sticky on this forum) and they are tested beyond 16psi. Also the stock cars with overboost (Z4 35is, 335is) run about 14.5psi for up to 7 seconds at a time, with all the cats in place and the stock intake. I don't think running 16psi for 12 seconds at a drag race would be that detrimental, especially considering that you have no primary cats, a free flowing intake and a low-pressure-drop intercooler.

At least this is my reasoning for deciding to go with Stage 2...

Well thats a good point..the fact your not making >16psi all the time is very valid..I will go stage 1 for sure and then maybe upgrade to stage 2...and try it out.. see what my boost gauge says..if I dont like what I see I can go back to stage 1..since there is 30 day money back guarantee for GIAC..lets c what happens..
