Performance Vauxhall - - TECH -

This is the kit most of you will be fa­mil­iar with. The suc­ces­sor to the Tech 1A, Tech 2 is a dealer-level di­ag­nos­tic tool de­signed for OBDII Vaux­halls built prior to the ar­rival of the Astra J. The unit is an im­prove­ment over its pre­de­ces­sor in al­most ev­ery way, from its large user in­ter­face to its com­pat­i­bil­ity with Con­troller Area Net­work (CAN) pro­to­cols via a ded­i­cated in­ter­face mod­ule.

Like Tech 1 and Tech 1A, Tech 2 is the most com­pre­hen­sive di­ag­nos­tic tool avail­able for the ve­hi­cles it cov­ers. In­stead of car­tridges, the unit makes use of 32MB PCMCIA flash mem­ory cards pre­loaded with the ap­pro­pri­ate soft­ware. “Tech 2 is the flag­ship di­ag­nos­tic tool and pro­gram­ming de­vice for Vaux­halls built be­tween the mid-1990s all the way through to the ar­rival of the Astra J,” says Marc. “It cov­ers pow­er­train, chas­sis and all body sys­tems, pro­vid­ing bi-di­rec­tional con­trol when per­form­ing di­ag­nos­tic or cal­i­bra­tion ex­er­cises, al­though op­tional Global TIS soft­ware is re­quired for ECU re­pro­gram­ming. Ad­di­tion­ally, Tech 2 can be used on HSV-de­rived Vaux­halls, in­clud­ing the Monaro and VXR8,” he tells us.

When pair­ing re­place­ment gen­uine au­dio equip­ment (e.g. up­grad­ing to a full-colour in­for­ma­tion dis­play and a CD70 head unit with satel­lite nav­i­ga­tion) or re­plac­ing the Col­umn In­te­grated Mod­ule (CIM), Tech 2 will be re­quired to ‘pair’ these items to your car. Keep in mind the fact Tech 2 is also re­quired to ‘di­vorce’ the parts from the orig­i­nal host ve­hi­cle. You’ll need car passes and their ac­com­pa­ny­ing se­cu­rity codes to per­form these tasks.

Be­ware of buy­ing a knock-off Tech 2 from China. These units might look ap­peal­ing when com­pared to the cost of a well-used Tech 2, but there have been many re­ports of repli­cas not be­hav­ing like the real deal, with some own­ers high­light­ing se­ri­ous elec­tri­cal sys­tem op­er­at­ing prob­lems af­ter plug­ging the Chi­nese kit into their cars.

Independent garages are likely to use non-GM di­ag­nos­tic tools (such as those sold by Snap-on) cater­ing for a wide va­ri­ety of ve­hi­cles from a high num­ber of man­u­fac­tur­ers. While these de­vices of­fer great func­tion­al­ity, they’re not as in-depth as gen­uine GM kit when it comes to de­tailed pro­gram­ming of a Vauxhall. Stick with the gear we’ve out­lined on these pages for the in-depth con­fig­ur­ing

of your car.
