New Product from TTR - QuadraMAP Sensor Module

Post by DonTZ125 »

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 here by Bruce Bowling 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 running the Extra code, 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. More information is available here.

Is it possible to view all 4 sensors readings in real time in tuner studio (or other software) to see if one cylinder is running alot different to the others and you could trim that cylinders fueling to compensate?

Not with the current design. It might be possible to modify the design, adding buffers and output wires, but for as often as you'd use something like that it might be more cost effective to use a home-made sync gauge and simply balance your butterflies with the sync screws on your TBs.
