Wideband and Dsp

[matman2492]

I recently found a dsp in my area for sale but i read that you "should" have a wideband to monitor a/f ratios. What do i need to do to my car to run a wideband as im pretty much stock. Im buying this dsp regardless as its a great deal just not hooking it up until i figure out how to support it

Uhh u just install it. Go look in the how to section and find Wideband install. That will show u everything.

thanks 617srt, im such a noob at the forums, never can find anything! great write up tho!

Yep its pretty easy, everything you need comes in the kit except for the gauge pod. I welded the bung in myself with a mig welder, thats the only part that might hang you up if you don't have access to one. Any exhaust shop should be able to do it cheap though.

[matman2492]

quick question, is the little ring u weld on threaded so the sensor stays in? or hwo does it stay in?

[Ratman]

Yes the ring (o2 bung) is threaded. It will come with the wideband. I would take it to a shop if ur not handy with welding. Or you can just buy a better downpipe that has one already welded in it.

What ever down pipe you install it on, make sure it install it BEFORE the cat if its catted.

ok so i bought the dsp and ordered a aem wideband, now im thinking exhaust...i have a stock exhaust so i was wondering if i should upgrade it to a 3" dp with the 02 bung already in it with a cut out the will connect to my stock exhaust, good or bad idea? or should i get a 3" o2 housing AND a 3inch exhaust? what are your guy's recommendations?

[Ratman]

I have a 3" in downpipe without a cat and LOVE it. It's loud as hell when u want it to be and when it's closed it sounds just a little bit better then stock. 3" o2 housing is up to you. A lot of people say the gains aren't worth the money. I put one on just because I figured I already got the downpipe off and its right there.

If you want to keep the stock exhaust then just get a 3 inch downpipe catless with a cutout. Will perform near to a full 3 inch exhaust.

O2 housing on the stock turbo isnt really needed. It will help slightly but its not worth the PITA it is to install.

[matman2492]

so mainly get the 3in dp with cut out that reverts back to 2.25in the stock exhaust is right? if i get a 3in dp tho how does it attach to the stock o2 housing? isnt it a different size clamp/bolt connector?

newbie at modding cars here, thanks for sticking in there!!

[tunerlover3]

Nope....Same 4 bolt setup.

okay so i got the wideband in my stock dp for now and got the dsp 93 tune loaded. im slightly overboosting, i turned the boost down by 5%1-2k rpm and 10% for the rest of the rpms ranges. im supposed to disconnect the battery everytime i even slightly modify the tune right? not just the main ones correct?
