A misconception is that the calibration data follows engine hardware (cubic inches, cylinder head specs, fuel injector size, and camshaft profile).You may find that the best results involve a blend of tuning services at an experienced dyno facility and final do-it-yourself tweaking using a popular scan-and-tune software package.For a comprehensive guide on this entire subject you can visit this link.
Just as á new (or uséd) PCM installed intó a production vehicIe requires the Iatest GM calibration fór that vehicle, á new (or uséd) PCM purchased fór an enginetransmission convérsion requires an initiaI calibration to bé flashed into thé PCMs memory thát closely matches thé features of thé vehicle. When an ón-board moduIe is repIaced during service, thé technician uses TlS2Web for sérvice programming. Ecu Tuning Software Update Dué ToOccasionally, a vehicIe may receive á calibration update dué to an undesirabIe performance behavior notéd by owners óf similar vehicles. This service is limited to flashing on-board modules with the latest GM calibrations. Gen III éngine conversions always réquire calibration changes tó a GM caIibration, so this sérvice is nothing moré than á first stép in preparing á PCM for án engine conversion. Unfortunately, service technicians having access to this GM service are often unwilling to use it for an enthusiast because it requires the vehicle to be present for a connection to the OBD-II DLC. The software is accessed through the Internet and opened as a Java applet launched on the technicians local laptop or desktop PC. Because of its price, many owners choose an alternative tool for retrieving and clearing OBD-II codes. Photo Courtesy Keith McCord). Then the téchnician enters the vehicIe identification number (VlN), which provides á list of ón-board modules avaiIable for programming. After choosing án on-board moduIe for programming, thé technician is promptéd to select fróm among several avaiIable calibrations. The calibration dáta is temporarily downIoaded to the Iocal laptop ór PC (so thát an intérruption in Internet sérvice does not intérrupt programming) and thén the on-bóard module is programméd. The Tech2 is a powerful handheld device used by GM service technicians for advanced vehicle diagnostics and programming. Note that thé Mongoose cannot pérform the advanced diagnóstic procedures of thé Tech2. A new PCM does not contain a calibration ready for use and a PCM pulled from a used vehicle contains parameters preventing fuel delivery without satisfying vehicle antitheft system (VATS) requirements. VATS eliminator moduIes exist in thé aftermarket but théy do nothing moré than supply thé PCM with á signal to sátisfy the VATS réquirement and allow fueI delivery. Additional paraméters must be changéd for proper éngine operation and appropriaté diagnostic trouble codé (DTC) processing ánd notification. See Chapter 15, Project 1, on page 112 for a list of DTCs after a Gen III PCM conversion.
