"translate" this please

Per example, the map of the edc15c2, a little translation and perhaps the units would be nice... ;)

SVRPL=?
N75
N75 2
N75 3
SVBL

SVRPL - Single Value Rail Pressure Limiter = Max aloved pressure in the rail. The rail pressure will never be higher then that value.

N75 - It is generic name of a map for elctronic valve duty cycle that controls the vanes of the turbo
N75 2 - the second one
N75 3 - the third one
There are more then one N75 maps. They are chosen by the ECU in diferent conditions.

SVBL - Single Value Boost Limiter = Max boost that is aloved in the system. The boost will never be higher then that value.

Is this Single Value the one that makes the car enter on so called safe-mode our in some cases, cut-off the engine even if driving? (my did that with box on the rail pressure)

Correct.
Tuning boxes interupt the signal between the ECU and the sensors. They alter the signal (lower or rise) and send it to the ECU. The ecu thinks that there is not enough pressure in the rail and closes the rail pressure valve to compensate. When you have higher pressure and same injetion time you can inject more fuel = more power. Fooling the ecu this way is not a good thing to do.

Thats why i want to learn how to remap ;)

In English the "safe mode" is also called "limp mode", it may help you in the future if you are looking for how to solve a limp mode problem. ;) ;)

Limp is not the same that safe-mode, many PSA's cut-off the engine when some value are achevied... (been there, done that ;) )

I have a few obd scanner, amoung then the Diagbox.

Oh sorry then! :roll:
what is the exact difference? Limping is when the engine power and revs are cut drastically, safe mode is when the engine is shut down because of some problems?

is it possible to make safe mod in fact tuned mod?this way it would be possible to switch to tuned mode(safe mode) during driving with just one switch(power for maf example) :D

According to my experience, yes, its quite that.

Never happened with your engine? I only eard this engine off situation on PSA's, but i talk more with persons who drive PSA's ;)
