Bring your M40B18 to life with this fully tuned, daily driven, and track tested performance chip. The SSSquid Tuning performance chip is the most complete tune on the market, with every aspect of the mapping being optimized from idle to wide-open-throttle.
This chip is compatible with:
- 1987-1994 E30 318i
- 1988-1994 E34 518i
- 1992-1993 E36 318i
**PLEASE NOTE** If you are using 19lb/hr Ford injectors, they are rated for 3.5bar fuel pressure, and will therefore actually flow less than the stock injectors on a stock fuel system. We recommend either purchasing injectors rated for 19lb/hr+ on a 3bar system, or upgrading the FPR to a 3.5bar unit.
