The AltezzaLink (TALTX) is Link Engine Management’s G4X plug-in ECU for the Toyota Altezza RS200 (SXE10) with the 3S-GE Beams naturally aspirated engine. An onboard MAP sensor is fitted. The PCB installs inside the factory ECU enclosure with no loom modifications, and includes a CAN-to-BEAN (Body Electronics Area Network) converter that maintains factory instrument cluster functions.
Lexus IS200 note: The AltezzaLink fits the Lexus IS200 (GXE10) only when a 3S-GE Beams engine swap has been performed. The stock IS200 uses the 1G-FE inline-6 and is not supported by this ECU.
The ECU transmits engine speed, coolant temperature, IAT, fuelling data, and AC requests over the BEAN bus to maintain factory gauge and comfort system operation. A second independent CAN bus is available for aftermarket devices.

Frequently Asked Questions
Does the AltezzaLink fit the Lexus IS200?
Only if the IS200 has been fitted with a 3S-GE Beams engine swap. The stock Lexus IS200 uses the 1G-FE inline-6 and is not compatible with this ECU.
Do factory gauges and AC still work?
Yes. The AltezzaLink includes a CAN-to-BEAN converter that maintains factory instrument cluster functions (coolant temp, RPM, etc.) and air conditioning operation.
Is a base map included?
Yes. A startup base map for the 3S-GE Beams is pre-loaded. Professional dyno tuning is required before use.
