My secs monitor has the ability to read peak boost up to 33psi, which is exactly what i run, but it will only read up to about 29, i take it thats because of the range of the map sensor? but o only have the choice of 2, 2.5 0r 3 bar map sensors

Any ideas if/how i can get it to read full pressure?

More worryingly than the SECS monitor seeing it, how are you fuelling for 33psi on a 2 bar? Or are you just chucking in 33psi worth of fuel at anything over 29 and excepting it running a little rich at 30/31/32 psi?

You are right, it is the limit of the MAP sensor.

You could put a bigger sensor on JUST for the monitor as there is
an upgrade to fit a 5 bar sensor (45 psi)


Sensor is about Ł100 ish (from others)

Upgrade is Ł10

chip-3door,

That is exactly how all chips over 2.0 bar work on Weber ,

I.E they fuel for your maximum boost at >2.0 bar


So if you have 2.5 bar then you get teh same fuel at 2.0 bar

SECS, yeah i know mate, and other ECUs too for that matter, just wasnt sure if he was doing that or if in this instance he had a seperate MAP sensor for the ECU and for the Monitor and the ECU one was 5 bar, if it was then i was going to suggest the upgrade to allow him to select 5 bar

its got a three bar sensor on it, 1 bar vaccum and two bar boost isnt it?

Stu specced the chip on 55lb injectors for 33psi peak, i have a shonky gauge to set the boost but i cant use the peak or warning function on the secs monitor now
