GYS battery stabiliser from £814.98
Do not tune a car without one. Writing a file takes minutes with the ignition on and the engine off, and if the voltage drops mid-write the ECU can be left with half a file in it. A battery support unit holds the voltage steady for as long as the write takes.

Why GYS 100A
Do not tune a car without one
Every dealer, every write. It is the cheapest insurance in the workshop.
The unit
GYSFLASH 100.12 battery support unit
100 A stabilised supply
The GYSFLASH 100.12 supplies up to 100 A at 12 V, enough for modern vehicles with everything switched on, during diagnostics, programming and showroom demonstrations.
Every 12 V battery type
Dedicated to 12 V lead-acid batteries of every type: liquid, AGM, EFB and gel. The 30.24 HF and 50.24 HF versions in the range cover 6 V and 24 V.
Protection
Automatic safety trip, reverse polarity and short-circuit protection, and an optional workshop trolley so it moves with the tool case.
In use
Set the voltage, clip on, forget about it. It also charges and conditions, so it earns its keep on service work too.
