im getting ready to wire my two steps in the car. O know of all the limiters in the 7531, but the 2 step wont have fuel control (obviously). I know I can alter the ve cells that the ecu sees on the TB but what are you guys using? bs3 or 7531 and why?

thanks guys!

 

I do just what u said, msd for rpm limited and Bs3 for fuel and timing. Just easier to do on the laptop. I have the external msd controller box too for quick 2 step adj at the line

 

do you ever regret not having the burn down limiter function since youre wired this way?

 

you can still use the spool rev limit feature-- using the bs3 to set the timing at that rpm is still just fine.
