Here we have ALPINA B10 3.5 performance chip for BMW M30B35 (3.5 liter, 6cylinder, 12valve) engine - e34 / e32 and e30 335i conversion.
The chip came of 1992 e34 Alpina B10 3.5 Kat (254HP, 325Nm). This is very rare item.
Performance gains on not modified 3.5 engine depends from the engine condition and other mods (like sport exhaust system, cold air intake system, etc.).
15-25 HP increase is expected. Responsive and smooth acceleration. Rev limiter moved to safe 6850 rpm zone.
Alpina B10 3.5 chip is also recommended for modified M30B35 engines. Especialy if you have setup similar to original Alpina engine:
- Ported cylinderhead.
- Performance camshaft.
- Oversized exhaust valves (+1.00 mm).
- High compression ratio pistons (~10.0:1).
- 6 branch exhaust manifold.
This setup will give 254HP, 325Nm power output.
The chip was tested with 179 ECU and is in 100% working condition.
I can also provide instructions how to install the chip, if needed.
Rev limit: ~6850rpm
