One of the most annoying parts of tuning ITBs is getting a good MAP reading - tee'ing the various ports together, especially with a plenum, will give a fairly smooth average signal, but it isn't the actual value. Test runs discussed on a different MotorSite by Bruce Bowling (yes, yes ...) showed a typical difference of over 30 kPa at idle between 'average' and actual MAP. We are now offering a 4-input sensor module that returns the lowest MAP reading. For those planning sequential spark or injection, it also monitors a designated 'index' cylinder and returns a 'cam' signal when that cylinder drops below 80 kPa (this value is easily adjusted by the user).

Different engines need different sensor ranges; we offer a variety of sensors. The QuadraMAP sensor module sells for US$125 plus shipping. More information is available here.
