Stage Tuning

Tuning is often offered in "stages", it's a useful rule of thumbs. Here's how Sal defines his stages.

Numbers are based on stock S85 dynojet figures of 430whp.

Stage #	Required Modifications	Expected Peak Power
1	None. I highly recommend the sealed air intakes.	450whp
2	Primary cat deletes & aftermarket long tube headers.	470 to 475whp
3	Optimized for V3 long-tube, equal length headers. Further mid-range gains of 10whp 4000 to 6000rpm.	490 to 500whp
3+	Custom tuning for S85s with cams, strokers and/or superchargers.	Case by case.

Tuning Process

Once your order is paid, I will communicate with you to validate your tune specifications. The tuning cable will be shipped to you.

1. Install tuning software to your PC (not Mac compatible).
2. Extract the OEM DME file using the OBD2 Cable & Tuning device.
3. Upload your OEM DME file to your PC using the software.
4. Email the file.

[..waiting period]..

5. Download the new tuned DME file to your computer.
6. Upload to your tuning device.
7. Plug into OBD2, turn on the ignition, flash your vehicle. *during the flashing process, it is normal to see lights, warnings and other electronic signals. It last a minute or two.
8. Turn off ignition, unplug the tuning devine.

Start your S85, and enjoy.

Always have your car on a battery tender during the tuning process.

Build Journal Entry

Like caffeine for your V10.

The BMW S85 V10 responds incredibly well to tuning.

More power, faster throttle and smoother power delivery [...] with a bonus reduction in fuel comsumption

I opted for a few options like cold start and VMax limiter delete along with increased rev limiter to 8,500.

It's nice :D

Enjoy,
