With the DataMaxx Engine Saver Kit you get everything you need to help tune and protect your engine. You can monitor Engine RPM, Driveshaft RPM, Transbrake, Oil psi, Water temp and 8 Exhaust Gas Temperatures. This allows you to know exactly what is happening inside that engine and if you are pushing it too hard. When we are looking at our data after our pass, the majority of it is spent looking at the Engine & Driveshaft lines and then the 8 EGT’s, so with the Engine Saver Kit, you get everything you need to take your tuning to the next level with room to expand.
