123ignition?

[Barry]

There is a setting in the 123-R-V 
I think it is the 1.7 Type 4 - curve 9 or 5

I have heard some people/mechanics do a modification to them one one of the other curves

The 123 Tune + is the one more suited for the 2L Type 4
But you need to tune the curve. 
They don’t come preset

This is the one I have. 
I got it through Andrew and he set it up for me. 

The Bluetooth gauges are very handy
