+1.

Everyone talks about how 'smooth' the flashes are, but looking at these graphs, you really can see how smooth(er) the Procede is. It continues to amaze me how smooth, consistent and powerful the Procede Autotuning is.

[e90_guy]

I remember someone mentioned GIAC S1+ couple months ago. What's the different between S1 and S1+? Is it available now?

Nice review. Diff considering getting this as well, expecially with a Flashloader coming out.

ehh not necessarily, I had more traction issues with the procede bc the tq was so strong down low. I mean that isn't a bad thing necessarily Both tunes are nice, i just prefer the flash for the reasons I already said and wanted to share some dyno's with you folks.

AWE told me its a half hour labor to flash the car again if bmw flashes over it. Like $57?

Those are very solid horsepower gains for stage 1. I REALLY wish we could get that 93 octane out west!

Thanks, now I want stg 2!!

Looks like you needed to retune your right foot, not your engine That kind of brings it back to what I said about how engine torque follows your foot with Procede. As it should, ideally, in any car. If one finds the power hard to control or un-smooth, it's is his right foot that is the source of the problem, not the tune. But if you prefer a flash over a physical install, that's a perfectly valid point.

Thanks for the review. After getting my JB+ I researched on what tune would be next. I ended up getting an excellent discount on the Procede so I ordered it.

I'll post a review once has been installed.

I've got to disagree. Smoothness is something inherent in the cars design. When driving the 335i, tuned or not, acceleration feels very smooth. When you slam the pedal to the floor, yes, you accelerate quicker, but the feeling of that acceleration is smooth. When you slam the pedal to the floor on a 911, even if it's slower than a 335i, the acceleration just "feels" so much more aggressive. I can't really explain it other than that, it's something you have to feel yourself in both cars. But I know that the way the 335i accelerates certainly feels much softer (even if it accelerates with the same times) than does a porsche 911.. and I'm not talking about the feeling in the steering wheel. I'm talking about a feeling of raw bone crushing bat out of hell power.

So if the dealer updates your DME, does it get over written?

Ah, just the topic I like talking about. I think it's important to define what "smoothness" is since everyone has a different idea. In this case, I don't think we are talking about mechanical smoothness/roughness which is dependent on reciprocating weight, engine internals, rod/stroke ratio, etc,. Those are the reasons that a n54 feels different than a flat-6 Porsche engine. If we are talking about those differences, we are actually talking about NVH (noise, virbration and harmonics). And that is a whole different subject that has little to do with EFI tuning and more to do with internal engine design.

Smoothness, in this specific case relevant to n54 tunes, is a product of throttle closure, knock retard and boost error. This is the only thing it can be since we are holding engine mechanics/internals constant and just changing boost, timing and air/fuel targets. The neat stuff about this bit is that it is VERY easy to quantify what tune does what by simply logging throttle blade angle (with respect to applied throttle), ignition advance (with respect to ignition setpoint) and actual boost (with respect to boost target). The last bit (actual boost) is especially interesting because there is a time-based error as well (turbo lag) that needs to get analyzed as well. Sadly, this is exactly the kind of stuff i do for fun.

Why do you have to continuously intervene into every post that mentions a Tune to justify your Tune , even when no one is bushing it vs. providing their view and reasons for making a switch, which OP made it very clear based on his thought process behind it.

BobS sorry if I'm out of line since it's your thread. It's just becoming irritating, that you can't read a thread started by a forum member about their experience with tunes with out Vishnu organization jumping on it like flies on the sh!t.

Politicians do it all the time. It's called spin or damage control. They want everyone to know that the reviewer wasn't really unhappy with the PROcede he just doesn't know how to drive his own car. You take the good with the bad on public forums and when the forum ownership allows vendor to post rather than just display banner ads this is the type of stuff you get.

[Brey335i]

I do believe that you should have had the newest update of the V4 and made sure the autotuning had reached its normal operation range before going on the dyno. Would have given us the most up to date and fair numbers.

Great power on that GIAC though... but what's with the fall in torque at 4000 rpm?

Tell us more. Why? Are you still covered by BMW warranty? Do you take your car in for service with the tune? The one - big - advantage of piggy is it takes less than 30 mins to remove it, while GIAC and any other flashes take a trip to have it flashed back to stock.

[kjrulz]

I would have gotten GIAC for simplicity and smooth reputable power gains. However I think it's ridiculous that they haven't gotten a flashloader completed yet. As perfect as they want it to be, it's completely unreasonable that it has taken this long.

Also, the JB3 and Procede have more flexibility as far as tunes go. You can set either one and forget it or you can have more fun and customize. The install is a pain, but typically you shouldn't need to be installing and uninstalling too many times so it's completely bearable.

Check out Prius, no problems with traction down low wtf? Why do you tune if you can handle the power? Ever heard of driver ed classes?

There's no need to attack his driving skills. You shouldn't assume his skill set.

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

Great gains OP!

Uh...JB3 puts down serious power but its not smoother than a PROcede... Not yet at least.

You can spin tires in almost any car, you just need to learn how to control it. Complaining about a tune being too powerful means two thing: 1) you don't know how to use it 2) you don't need it

shiv you know I'm not a big fan of your marketing tactics, but if you can find a way to make the 400hp you get from an N54, feel like 400hp from a ferrari, I'll be your best friend. I love that "slam you into the back of your seat" feeling of acceleration like I had with the F40, or McLaren, or even 911, and I just don't feel that from the 335i even though hp numbers are high enough.

You can turn off auto clearing right? Besides I think the only codes deleted are tuner codes and some other ones that have no real bearing on issues your car might be having.


Also, do you have to buy a BT w/GIAC to clear tunes/codes?

In your example you said that if your car breaks down you wont have access to youtube to remove the Piggyback. Would you say its even more difficult to tow the car to a GIAC dealer so that they could take the flash off before going to the dealer?

It looks like you are happy with your selection, which is what its all about .
