E30 Alpina B3 Chip


Sold By SSSQUID Categories: , Tags: , , , , , , , , ,


This chip is a bit-for-bit reproduction of the original Alpina B3 M20 tune. This is not customizable (e.g. injector size, “stage”, or octane), and is intended only for use with the stock B3 injectors (apprx. 18.25 Lb/hr; same injectors used on M42B18 and M30B35). The tune was designed for 87 AKI fuel.

This chip is NOT A GOOD SOLUTION FOR THE STANDARD “2.7I” OR “327I” BUILD! If you are looking for a proper tune for the ETA block + 325i head, look HERE.
