Emissions on KAT

[chandler]

Whats goin on guys, My problem is that I have a 96 240sx, well not a problem..... it needs love and all but... ahh well... My qestion is, I wouldl like to keep it some what legal, high flow cat and all. But I want to keep most of the emissions so I can pass inspection with out greasing some palms. Is there a way to reprogram the ecu to not do a few of the tests? or will I have to rig a few things up. Also I was looking at the AEM EMS, I was told it wont let me pass OBD2 inspection In NC. Thats why Im leaning toward the emanage ultimate. Any and all comments, oppinions and facts will be appreciated, well maybe not all comments but hey im game

I dunno about in terms of the OBII scan, but you can pass the normal hydrocarbon tests and the like, it just involves having a conservative tune. I've heard of RB25's passing and have friends with 10 second DSM's passing emissions lol.

if you have the obd2 port scan like ny does, you wont be able to pass with the aem.im trying to make my car a 95 to get around that.

as far as i remember as long as you keep the ecu from throwing codes on 96 and up cars, you should be fine with emissions testing as they don't put it in the rollers.

as for the EMS yeah you are most likely gonna have to go with something else, unless you befriend somebody in the emissions testing place, then he/she could pass it for ya:)

With 96 and up cars they do put them on the rollers, and you have to pass the OBD2 scan, at least in CA you do. I have a 96 JWT ECU, all my emmissions equipment hooked up including routing the EGR into the downpipe, and I passed.

-Exactly correct. As long as the ecu is not throwing any codes you instantly pass emissions. EMS will not support OBDII diagnostics so you fail...although some states (IL) allow you dyno the car as a secondary test. Emanage is a piggypack so your ecu will still be handling all of the emissions controls. If you are going turbo you there are two areas which will throw codes :1) EGR temperature sensor: You will most likely cap off your egr system (unless you are using the Greddy kit which has fittings for your stock egr) you will have to install a 10k ohm, 1/4 watt resistor in place of the egr temp sensor. 2) Rear oxygen sensor: unless you put in a high flow cat and move the second o2 sensor behind it you will throw a code. All you have to do is pick up an oxygen sensor simulator (http://www.o2simulator.com connect it to power and splice its signal into the signal going from your o2 sensor to the ecu. Before I installed the turbo I ran for year with no cats and passed emissions with no problem. I just took care of the egr code and have had no codes for over a month now.
