I've got it on my vehicle. Pretty hard to contact during awake hours due to the time change but super helpful. No issues here thus far. Are there more sophisticated standalones out there? Sure, but I didn't want to chop up my harness and modify the car too heavily so this was my avenue. I'll add that you should be WELL versed in fuel injection theory and tuning. If you're expecting him to tune your car for you, that's not the case. The base map for ignition, fuel, and settings will get you going but you'll need to come up with the rest of the knowledge on your own. Won't be like dropping the ECU in and away you go...
