Engine management wise after tuning so many different ecu/ems's over the years I found Maxxecu about 10 years ago and was blown away by its flexibility, logging, and fuel modeling. And especially its motorsports capabilities like power management.
Since then I have become almost exclusive to Maxxecu but I do still tune Motec, Haltech, Emtron and EMU from time to time.
I have it controlling twin plug coil on plug for the ignition side, a head temp thermocouple attached to cylinder 3, temp sensor on the breather cover, air temp sensor in air filter housing, oil temp and oil pressure sensor on the stock oil pressure switch location, two 4.2 lambda sensors one for each bank, a Bosch idle control valve, a Plex SDM200DLG display that feeds back vehicle ground speed from its on board 25hz GPS and 100Hz 6-axis Inertial data back to the Maxxecu via CAN.
