Tuned by MAR

Custom tunes, built from your own datalogs.

Remote tuning for S58, B58, S55, S63 and S68 engines on MHD or bootmod3. Stock or upgraded turbos, with flex fuel as an add-on.

Build your tune How it works
What every revision works toward: boost actual (solid) tracking boost target (dashed) across the rev range.

How it works

  1. Order

    Pick your engine, turbo setup and flex fuel, then tell me about your car and mods.

  2. Flash and log

    I build a first map for your exact setup. You flash it with MHD or bootmod3 and send me a datalog.

  3. Dial it in

    I go through every log and send revisions until boost, timing and fueling are right for your car.

Prices are per car and include revisions from your datalogs. Your MHD or bootmod3 license and flashing hardware are bought separately.

Questions

What do I need before ordering?

A flashing license for your car (MHD or bootmod3), the cable or WiFi adapter that platform uses, and a phone or laptop to flash and log. For flex fuel you also need an ethanol content sensor installed.

MHD or bootmod3?

Both work. If you already own a license, use that one. If you're not sure, choose "Not sure yet" and I'll recommend one for your car before you buy a license.

What counts as an upgraded turbo?

Anything other than the factory turbo: hybrid and upgraded turbos, and single turbo kits. Enter the make and model when you order so I know what I'm calibrating for.

What happens after I pay?

You get an order confirmation by email, then I follow up with logging instructions for your platform. From there it's flash, log, send, revise.

Can I get a refund?

Yes, in full, until I send your first map. After that the tune is custom work for your car and isn't refundable.

Terms

Your setup. Each tune is written for the car, parts and fuel you describe. Tell me before you change hardware or fuel, because a tune built for one setup can damage an engine running another.

Licenses and parts. Flashing licenses, cables, adapters and ethanol content sensors are sold separately by their makers.

Refunds. You can cancel for a full refund until I deliver your first map. After that, tunes are non-refundable.

Risk. More power adds stress to the engine and drivetrain, can void your warranty, and is at your own risk.

Off-road use. Tunes are for off-road and competition use only. Changing an engine's calibration may not be legal for street use where you live. You're responsible for following the laws where you drive.
