In simplest terms, HP is good for those that want it simple and quick, EFI is for those with a little more depth. systems, Purge canisters, etc, etc as is often prescribed by GM diagnostics that I have.

These vehicles are always throwing codes (which up until now, I’ve used an ancient version of AutoTap to get the codes and freeze frame data), but I’ve had no ability to run commands to turn on EGR’s, Secondary A.I.R. I’m constantly maintaining a fleet of GM vehicles. What I need, and why I wanted a GM Tech2 was because I’m a diagnostic person. My DD, if I did anything on, would be purely settings here and there. Thing is, I’m not a tuner! I’ll leave the tuning of my car to Jim and company at Speed Inc. I REALLY wanted a Tech 2 (I’ll explain why I a bit), but she reasonably couldn’t afford it, as such, with Fraser (at Speed Inc), she was thinking that this would answer my needs. My Wife got me an HP Tuners (standard package I believe) for Christmas. There are other things I’ve had to command on/off that I can’t remember, but they’re not just commanding the fans on/off as their quote above states… This is not enough information on knowing whether or not this is as capable as a Tech 2 for diagnostic usage. Command fans, closed loop, gear select, timing, air fuel ratio and more real time! No editor package can be considered complete without comprehensive scan tool capabilities. It also allows viewing of vehicle Diagnostic Trouble Codes (DTC’s) and other vehicle information.

It allows viewing, charting and logging of diagnostic data in real time via the vehicle OBDII diagnostic data port. I read HP Tuners site, and there was only a paragraph blurb on HP Tuners diagnostic capability. No comment on China knockoff quality, I mean a working tech2 scanner, Chinese made or not. If you’re doing a lot of work on GMs or want to get a lot more in depth with your car, it’s worth the money. Is it worth if you just want to read/clear codes on your own car once in a while, heck no. So both have pluses/minuses depending on what you want to do. Only way to disable TPMS is the LG box, or rig up sealed tube at set pressure and put the TPMS sensors in it. HP Tuner also graphs out the data for you, a tech-2 you simply have a small screen with some #’s on the right in a list format.īut, Tech 2 can only change/do stuff GM intended where HPT can change all kinds of tables GM wouldn’t want us messing with. HP Tuners can do both, for a heck of a lot less. What works better and has more control over all the computers settings? Can HP tuners & EFI live do the same things as the TECH 2?
