Haltech Elite 1500 is a 53-pin wire-in Haltech ECU on 3 connectors: 34pin (28 pins), 26pin (23 pins) and AUX (2 pins).
It has 4 injector outputs and 4 ignition outputs. The injector drivers are peak-and-hold, so low-impedance injectors run without a resistor pack. The ignition outputs are logic-level. Smart coils plug straight in; dumb coils need an igniter in between.
There are 2 dedicated trigger inputs, each happy with a VR or a Hall sensor. One knock input covers an inline engine. Wideband control needs an external controller, usually over CAN. The MAP sensor is built in.
Drive-by-wire is native: 1 throttle from its own H-bridge outputs. Two CAN buses handle dashes, PDMs and expansion. Two outputs can switch 12V as well as ground. The maker rates the 5V sensor supply at 100 mA in total.

Which builds it suits
Of the 58 swap presets in the planner, 0 fit as they are and 14 fit with add-ons; 44 do not fit at all. The add-on it asks for most often is the Haltech WB1 (single-channel CAN wideband). Where it falls short, it is usually not enough injector output (low-side). The planner fills anything a preset leaves open with its ordinary defaults, so your own build may land differently.
The Nissan SR20DET (S13) needs Haltech WB1 (single-channel CAN wideband) and Haltech HPI8 High Power Igniter (8-channel). The Subaru EJ/FA EJ25 turbo single-AVCS (EJ257 2004-07) needs Haltech WB2 (dual-channel CAN wideband). It can't run the GM LS1 (Gen3 5.7 alum): not enough injector output (low-side). It can't run the Ford Modular 4.6 4V Cobra (NA, cable): not enough injector output (low-side). It can't run the Nissan VQ35DE (base, 2003-04): not enough injector output (low-side).
