OBD1 E36 Tunes

BMW E36 OBD-I OTS tunes for supported M50 and M50TU six-cylinder engines. This collection does not cover four-cylinder 318i or 318is applications. Confirm the engine, ECU, intake manifold, injectors, camshafts, headers, exhaust, fuel, and transmission before selecting the calibration stage.

For help choosing compatible hardware, read the naturally aspirated E36 build guide. If the project also needs a valve cover, the M50/M52 aluminum valve-cover guide explains the required one-bolt or OBD-II-style coil arrangement, gasket design, and crankcase-ventilation considerations.

Poverty Built covers the supported combinations listed on the product page. For a one-off build requiring revision-based calibration and datalog development, use UNDSPTD. bespoke tuning.
