if i get a tune like the jb3 or vishnu, can i set a maximum psi that the car wont go past?

Yes really, do you have a loss of memory from before? I personally have access too/have seen the tables - if you can't go past 14psi number you are using inferior software and tuning methods or you are using the stolen N54 flash that was floating around AKA, it's not going to happen with a Dimisport.

Real flash tuners started with the correct editing software from the get go, JM2C.

Yes for both.

On the JB3, you can choose a map with a certain boost target noted in the documentation.

On the PROcede, you can set a user programmable maximum boost target for the autotuning not to exceed.

Theoretically, yes. But the control methodology allows for some deviation some setpoint.

Only GIAC and Evolve i think managed to do this.

This is true. After months of research, talking with tuners and BMW technicians I decided to go with GIAC.

Of the common tunes I think the safest ones in order are GIAC>Dinan>JB3>Procede>JB+ = SSTT. What do you all think?

Sorry to say, this isn't close.

Safe is measured multiple ways, but primarily the boost run dictates the safety net, and the ability to decide what boost to run can be a double edged sword. For instance, with both the PROcede and JB3, you could dial in less boost than either Dinan or GIAC. That would make the PROcede and JB3 safer but add in the ignition offsetting of the PROcede and it would be the safest.

However, most people, when they have the ability, like to push the envelope. So the ability to run more boost is often used thus making the piggyback tunes less safe.

The key point is that the tune is not the issue. It is the individual using it. A single grading system does not work when the human aspect is included.

You are abosolutely correct. My comments relate to the driver pushing the tune to its maximum. Do you agree that GIAC and Dinan are safest at the limit?

Please explain how you think JB3 is safer than Procede? And I think it's a super hard thing to define and test safety.

My methodology is not very scientific but if you look at the number of posts (on several BMW forums) it seems that the number of problems per units in use is higher for Procede. I may be wrong. Please explain why Procede is safer? I am glad that you agree with the GIAC and Dinan flash being the safest.

Please post a screenshot of the original DME software showing boost tables of 16 psi.
