Is there a way to run 2 pcm's with a 2 way switch so u can run a 3.4 set up for better gas mileage and like a 2.8 set up so you can race?:th_confused:
 


well im ic mine by next month and i now u can run a 3.4 on it and go to a 2.8, but i wish u could run two pcms so one will have a 3.4 set up and the other has the 2.8 set up and could switch with out tuning
 
the pullies thats fine and easy, but im talkin so you dont have to retune it you would just have to flip the switch
 




just get your pcm tuned and get another tuned for the 2.8 and swap them out it takes less time to swap the pcm than it does the pulley.
 
no one power but everything goes back to the pcm that has to do with the engine and you would need to duplicate it and have a way to turn each pcm off so you can use the other pcm
 
dude seriously? wtf would you do this for?

the car drives the exactly same on a 3.8 versus a 2.8 except when you get into the throttle. this is dumb.
 


yea connect one power to a switch then run the power trom the switch to the pcm and repeat for the other pcm, that how u could turn one or the other on then go to the junk yard and get a pcm and the connector and splice into the harness, if im thinking right
 
You could maybe utilize a performance shift button, and adjust the performance shift tables for the 2.8 pulley. And only use it when you have that pulley installed. I'm not sure if you can change the fueling and all though with performance shift... I'm just starting with hptuners.
