the haltech e8 is packed with more features than any ecu in its class by more than just a quarter mile. the all new e8 performance ecu is for those who are on a budget and need full sequential control for their engine. the haltech e8 ecu is an ecu capable of controlling sequential injection on 2 and 4 cylinder with semi sequential 6 and 8 cylinder applications. with 8 channels capable of controlling injection and ignition duties, the e8 can support most modern engines with multi-coil ignition systems, as well as conventional distributor ignition systems.in addition to controlling fuel and spark, the e8 can control various auxiliary engine functions. stepper motor and bac/iac closed loop idle control closed loop boost control soft cut rev limiter tuning via tps with manifold pressure correction - ideal for those multi-throttle body turbo cars such as, gtir pulsars and gtr skylines. o2 sensor closed loop mixture control 32x32 mapping structure on board data logging (up to 200 samples per second) user definable mapping points numerous correction maps to ensure smooth drivability under varying operating conditions windows software the ability to calibrate just about any sensor for oem applications and of course all the usual outputs you would expect to find in a haltech engine management system.
