Trond Retterholt Posted July 19, 2011 Report Share Posted July 19, 2011 Hi, Just dyno'd the engine and found that I was boosting on 1.2 bar. I would like to install a 0,7 bar wastegate spring and adjust boost electronic by ecu and the installed mac solenoid. How do I build the boost table to make this work? I'm thinking that I will activate boost mode to "open loop" and Load index at "Boost adjust" Then I'm not sure how to set table to reach 1 bar. Is is possible to have a switch inside the car that activated this table/solenoid to be in use and deactivate when want to run 0,7 bar all over?

Simon Posted July 25, 2011 Report Share Posted July 25, 2011 I would suggest starting with 5% in the table and then work up from there. The Boost adjust option is if you are running a trim pot to allow cabin adjustable boost. As a starting point have a look at some of our base maps. The V7 Subaru one would be a good example. It has boost scaled off TPS. The Help file is a very good point of reference also. Simplest way to get 0.7bar would be to switch the solenoid off.

Trond Retterholt Posted July 25, 2011 Author Report Share Posted July 25, 2011 Simon, I ended up with value 37 in boost table. I would like to switch between 1 bar and 0.7 by switching the solenoid off. I assume I just cut 12 v power to solenoid by a dip switch. I have the solenoid connectet to aux output 4, which is port 19 on G2 unit (orange/yellow cable). Is this the cable that controls the boost solenod and the cable I connect the dip switch too ? Quote Link to comment Share on other sites More sharing options...
Simon Posted July 26, 2011 Report Share Posted July 26, 2011 Breaking the circuit on either wire to the BCS will do the trick. Quote Link to comment Share on other sites More sharing options...
