im so confused
thanks

There is no low impedence or high impedence Rtek. There are no low impedence or high impedence ECU's. The difference in the low impedence and high impedence s4's is simply the engine harness (your 87 has a factory resistor pack for its low impedence injectors). The 87 ECU (N332) and 88 ECU (N333) are essentially interchangeable.

If you have an 87 T2 with low impedence injectors and your stock resistor pack is working fine, it doesn't matter if you have an Rtek 1.7, an N332 ECU, or an N333 ecu.
