Theres a superchip on ebay at the mo for a 75 ts, will it fit an early `93 155 2.0 ts by any chance. The engine setup must be very similar. AFM etc very alike, although engine turned round and fitted transverse.
Find out what ECU number (and version) it's for. The 75TS engine used dizzys instead of coil packs and they also didn't have a cat. These factors I think would affect how the chip is tuned for the engine.
The short answer is I don't know, but I don't think it would work.
