Everything you need to know about: The GTSFO kit

This is the GTSFO kit- the one kit designed to completely overhaul your GTS into the powerhouse it wants to be.

(This video is rough and unpolished, until we can make a cleaner version, this is what we've got. Thanks for being patient with us)

Here's more written installation instructions which will be moved into this page soon

What's included in this kit?

The Thor400 with a GTS mounting bracket.

The Thor400 is mounted with included M3 allen screws, and the bracket is mounted with M2 allen screws.

Amass LCB30 Male TO XT60 Female Connector

This connector adapts the GTS's battery harness to the Thor's battery connector.

The GTSFO 12v RGB lighting kit

A 12v RGB status bar. LED count 10. Is an adapter for the power button and potential can-bus from the rear (can-bus currently unsupported).

A 12v RGB front status bar. LED count 14.

A 12v RGB rear bar. LED count 15.

The LEDs on Thor's work in a chain; STATUS - FRONT - REAR. In this case most of the inputs are routed through the status bar itself.

The VBMS

The VBMS is our newest smart BMS- a collaboration between Fungineers and VESC. It is mounted on a breakout board designed for stock 27s Future Motion GTS's.

The VBMS breakout board comes with it's own fuse mounted on the breakout board. THIS KIT DOES NOT COME WITH A SEPERATE INLINE FUSE

Documentation and specs for the VBMS can be found here

The Superflux HS / HT (optional, the Superflux will NOT work in an XRC frame as we don't currently have axle blocks for it)
Superflux Mounting Blocks / Hardware kit for GT (optional)
Superflux Female Connector (optional)
A stock GT motor connector (optional)
GTFO Tool Kit

Our kit also comes with a toolkit. It includes;

-A T9 Security Bit

-A 2mm S2 Hex Bit

-A T25 Security Bit

-A PH1 Phillips Bit

-A T20 Security Bit

-A Socket Wrench for these bits

-A Wrench for the Axle Bolts

GTSFO Programming Guide

Ok read this carefully, this is our GTSFO set up guide. THIS KIT DOES NOT COME PRECONFIGURED, PROGRAMMING IS REQUIRED AFTER HARDWARE INSTALLATION.Due to the multiple configurations of motors, we are not able to accommodate for every configuration yet. The kit will need to be programmed, the video below will walk you through step by step with either FloatHub or Vesc Tool. This video is designed with both the GTSFO and GTFO kits in mind. These two boards have slightly different values that are completely incompatible with one another. Please use the correct set up values for your device.

Set up values;

(These values are found in the initial Motor Wizard)

S-Count: 27

P-Count: 1

Capacity: 4.5ah, Full Voltage 113.4v, Empty Voltage 81v

Discharge Current Max: 45a

Charge Current Max: -35a

Motor Set Up Values (The CURRENT values used for a Superflux don't work for a Hypercore, vice versa)

(These are found under MOTOR CFG - GENERAL - CURRENT)

**Superflux Current Values: **

Motor Current Max: 160a

Motor Current Max Break: -160a

Absolute Maximum Current: 240a

Hypercore Current Values:

Motor Current Max: 120a

Motor Current Max Break: -120a

Absolute Maximum Current: 180a

(These values are found in MOTOR CFG - VOLTAGE)

Low Voltage Motor Cut offs; 67v Start (2.5 x S-Count), 62.1v End (2.3 x S-Count)

(These values are found in REFLOAT - SPECS)

High and Low Voltage Pushbacks: HVT - 116.1v (4.3 x S-Count), LVT - 81v (3 x S-Count)

(This value is found in MOTOR CFG - FOC - FIELD WEAKENING)

FIELD WEAKENING: 0a (You do not need field weaking for this HV board, although you can add some at your own risk. Ask Fungineers for advice if you wish to add more)
