I think I read in a magazine that said it did but how do we know for sure? Also if you have the obd2-1 jumper and use an obd1 ecu on an obd2 engine.. will the engine act just like an obd1 engine becuase of the ecu? Stupid questions probably but any help would be appreciated.

 

The motors respond about the same, but the obd1 allows more work to be done without the ecu freaking out and throwing codes. As far as I know, basics like I/H/E work the same and are well below the obd-2 freakout point. What bolt-ons do you have/want?

Fact.

Sort of

OBD2 has some capacity to "learn" It will actually detune your engine as much as it can to help improve emissions. the initial gain is relatively close. but in a few hundred miles, OBD2 systems have tuned out some of your hp gain to improve your emissions. if you clip the battery backup power to the ECU it still does some detuning, but it "forgets" everything when you shut the car off.

I did this mod a while back. I have no dyno to show a power gain from it, but my gas mileage went up about 2-3 mpg on average. thats enough to convince me.
