hopefully a instruction manual came with your diablo....

there are a couple things you have to do and the manual will tell you.

On the diablo sport you should be able to plug it in scroll down the menu and it should be pretty straight foward

Question for you, when you do shut off the 02s, well I had the "check engine" coused by x-pipe shut off, which means shutting off your 02s, will the "check engine" light come back on when your o2s fouklf out? I hope you understand what I'm asking here. Recently my car started running funny and I believe it's the 02 sensor but they were shut off when I had the car dyno tuned.

You have two sets of 02's....The first set closest to your headers play an important role in monitoring A/F ect.....you need those to be connected or you'll have issues.

The second set, towards the rear of the car are strictly for emissions only. They will not have any affect on performance if they are not connected. This is the set people turn off when adding an aftermarket x or h pipe

If your having driveability issues you might want to check to see if both sets of 02 sensors are shut off rather than just the rear set. I'm not sure that this answered your question cause I'm not clear on exactly what your were asking.

well it answers my question, I had this chip done about 3 years ago and about 2 weeks ago started having problems. The car would idle funny and anything below 2500 rpms would miss and statter, I cleaned the MAF and it seemed like it went away, than 3 days ago samething happned, it seems like it's doing more when the car is at normal temp. I order a new set of 02s and will replace them next time it happens.
