Bring your E30 M3 or other S14 equipped vehicle to life with a 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, including many ECU firmware upgrades utilizing modern techniques and instrumentation not previously available.

These firmware-level changes increase the ignition and fueling calculation speeds of the ECU, bringing this ECU’s performance far beyond the factory level.

This chip is compatible with:

  • 1986-1990 E30 M3


0.5 18 25 400
1.0 25 35 500
1.5 40 55 700
2.0 55 70 900
2.5 75 90 900
3.0 85 100 1200
*over a stock vehicle on a stock tune. HP/TQ numbers are general estimates and will vary.

Don’t know what stage you need? Looking a little advice? Please see the GETTING STARTED page or CONTACT US for more information!


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
