HELP!! OBD2 Question

[Blackhorse6]

I have read several articles and still do not have a clear picture of the effects of OBD2. Will it really de-tune any bolt on performance mods that I/We may put on our cars? Any help is GREATLY appreciated

I don't have much data on individual mods, but my 96 with I/H/E and IEM from comptech does give it 289 hp to the wheels,so HAL is allowing something.

OBD2 is what they came up with to standardize the way ecm codes are read and they also have a generic set of codes that all the manufactures use for the same faults. Some '95 model cars and all '96 and up cars are equipped with OBD2. The newer a car gets more systems are monitored. As far as OBD2 de-tuning your car, the manufacturer of the mod you are installing has to come up with a way to make it compliant with OBD2. That is why in California it is such a hassle to get some things CARB certified (California Air Resources Board). So OBD2 or non OBD2 your mods should work if designed properly. Hope this helps.

I do not think that OBD-II will hurt the performance on the car. I supercharged a 98 GS-R and was putting out some good power with OBD-II.
