Repeat the save process and go to the next profile. For low range you may need to start over as
with Profile 1. This is due to the speed settings that will be different.
Once you are familiar with tuning you may tune the middle and top dots also in the up and down
dimension. This is mostly a feeling by you if the transmission do what you want it to do. Try to see
what the marker does while driving and try to get the shift lines where the transmission feel
smooth. Be careful while driving as you may get distracted and cause an accident.
10. Fault Finding
10.1 Faults and Remedies
10.1.1 The TCU yellow LED does not come on
1. The ignition wire does not have 12Volt
2. There is a short on the 5 Volt output from the TCU. The magnetic crank or distributor
sensor and the TPS sensor as well as the profile switch, if any, use 5 volt. Check the
wiring.
10.1.2 The Software does not Connect to the TCU with the USB to RS232
Converter
1. Pin 1,4,6,7,8 & 9 must be broken out to operate. See RS232 Computer to TCU interface
2. The Baud rate must be set to 19200 in the Device Manager.
3. No Driver for this Device installed – The USB converter must have a driver CD which has to
be installed first.
4. Too high Comp Port allocation for the driver. See Changing the USB Comport in Windows
Device Manager
5. Faulty USB converter.
11. Specifications
These specifications are for the advance TCU combinations. This means that not all may be
