SKU: chp-m42b18 Categories: , , Tags: , , , , , ,


Bring your M42B18 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. Not only are SSSquid tunes the most complete software solutions on the market, but they go beyond ignition and fueling, often including ECU firmware upgrades utilizing modern techniques and instrumentation not previously available.

This chip is compatible with:

  • 1988-1992 E30 318i/iS

**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.

If you are using a Bimmerheads Cam and/or Performance Head then I highly recommend you go support them by buying the specific tune directly from them! These tunes can be purchased on their website at
