Can be used instead of G2 adapter.ĬABL1– Used to connect an ALDU1 or APU1 and a pre-1995ĬABL2 – Used to connect an ALDU1 or APU1 and a 1995 carĪPU1 – Combines the functions of the BURN2 (programming chips), Ostrich 2.0 (real time chip emulation) and the ALDU1 in one unit Applications Socket Booster – required for use of Ostrich 2.0 in TBI applications. Ostrich – USB Chip emulator, allows realtime changes while engine running Used to read stock program on memcal ECMs. HDR1 – Header that allows reading memcals in a BURN1/2. G4 – Blue Memcal style chip adapter for some 94-95 vehicles G3 – Multiple program switching version of G1 G2X – Multiple program switching version of G2 G1 – “Memcal” style chip adapter (TPI, Syclone/Typhoon, 94-95 TBI, 92-93 LT1, etc.) Instead of buying the BURN2, Ostrich2 and ALDU1 separately, you can buy the APU1 unit that does the functions of all three pieces in one unit. For the 1995 model year, CABL2 is required due to the physically different connector.
For 86-94 vehicles, CABL1 is required to connect the logger and the vehicle. Logging from the computer is accomplished using either an ALDU1 or the logging facilities of an APU1. Alternatively, you can either use the Ostrich 2.0 emulator or the emulation facilities of the APU1 to make changes while the vehicle is running.
You can burn chips using a ROM burner such as the BURN1/2.
The same EPROMs can be used for all of our OBD1 GM products (except the switching adapters…) which is usually the 27SF512 – C2.Īfter a chip adapter has been installed in an ECM, tuning can begin. Some chip adapters require soldering for installation (G2, G2X) but most do not (G1, G3, G4, G5). First, a “chip adapter” is used to convert whatever the ECM in question needs into a form that accepts a 28 pin EPROM. The process for tuning OBD1 GM products is pretty much the same for all 86-93 model years. Many Grand Prix from these years use the G4 adapter. Some (like the 94-95 TBIs) use a G1 adapter. Many of these ECMs support being reflashed over the ALDL interface (e.g. Hardware for OBD1 GM Overviewĩ4-95 model years are oddballs. All the vehicles of this generation speak the ALDL protocol for logging/vehicle communication.įor purposes of this guide, “ECM” means Engine Control Module, Powertrain Control Module (PCM), Engine Computer Module (ECM) – terms will be used interchangeably to mean the same thing. These cars used several different types of engine controller – some have one injector for each cylinder (Tuned Port Injection, or TPI along with the LTx motors) while some have fewer injectors that are placed near the throttle body (Throttle Body Injection, or TBI) instead. When we talk about “OBD1” GM vehicles, we mean vehicles made from (approximately) 1986 to 1995. Our CRTD4® range of products can also be reprogrammed for use in over 90% of other turbo Diesel and Petrol vehicles, meaning you can change your vehicle often as you want safe in the knowledge your CRTD4® can be used again.(eventually this page will have more information) Basics
In addition our Multi Channel model also remaps Turbo delivery by having it activate earlier in the rpm range making acceleration smoother, and greatly improved.įor domestic vehicle owners, the CRTD4® Multi-Channel represents great value with its seven operation mode settings which allows owners to adjust power and torque output between maximum economy and maximum power, perfect for switching between everyday driving and long-haul trips. The engine fuelling profile of the vehicle is then altered to improve power and torque delivery whilst eliminating flat spots in individual gear acceleration arcs, creating a smoother and more responsive drive experience. With custom designed and engineered micro-processor architecture the CRTD4® remaps vehicle performance moment to moment based on data received via the engine sensor interface harness. The CRTD4® Multi-Channel Petrol Tuning Box for the Alfa Romeo Giulietta 1.4 TBi Multiair 168 BHP / 170 PS / 125 KW / 250 NM / 184 LBFT from TDI-Tuning is at the cutting edge of digital tuning box technology and represents a revolution in vehicle remapping.
