^Thanks.

Getting my car tune soon and I would like to use the secondary tables for some high octane high boost tuning. My question is how do I wire it to a switch to switch the two map? I see there is an AC switch too. Can I just use that? Is there anything I need to do to make the AC switch work? My AC is ...

OBD1 doesn't have a "C" connector.

I doesn't matter where the ELD pin is on your harness. Once once you use the jumper harness it's coverting to an obd1 plug where it should still be at D10. The ELD pin on my obd2a harness was a D16. Once I use the jumper harness to run my p28 it'll still come back to D10.

A30, the green/red wire is where you need to tap into on an obd2b. I just did the aem wideband install into my 96 coupe using the ELD pin 2 weeks ago. Of couse, I also cut out r136 and r138. Works great.

Got it. Thanks a bunch.

I am having problems with the display. If I click on the Display window I'm just getting is a message saying "Floating point division by zero." The display window where you upload other display disappear also. What can I do to get the display back and working?

I think I got it. Thanks.

I just install my AEM uego into my s300. Wire the white wire from the wideband into ELD pin. Disable ELD it in misc. Romover R136 and R138 from the ecu. Now, my ELD display is reading it volt. How do I covert it so that it'll read air fuel ratio over volt. Thanks.
