Mine was just more habit. Every DSM that comes thru gets the same treatment. But typically involve DSMlink and I can simply disable the lights for all the emissions components with a click. Then I physically remove everything as well.

With the Evo leaving them in place was just a simple work around in removing all the needless feet of vacuum line, hard line junctions, brackets... IM stay... etc. I'm not saying MY WAY is always the right way. More like, this is what I did, and this was the result. But from past experience with DSM's I knew that leaving them plugged in, would avoid the light. Which is what I do on cars without link.

In other circles the FPS is regarded as unnecessary and is commonly removed, or wired up for other purposes. Again, do as you wish, I am not being a proponent of removing it - only stating that I deactivated its operation. Without a light, by leaving it in place. I might not have touched it but the previous owner had this ghetto double tap (for two gauges) jammed into the confined area around it. Add the lines from that solenoid and = rats nest. In part due to frustration, I decided all that sh*t had to go.

My primary purpose in removing such items is simplicity. Coupled with an overwhelming personal distaste for anything that complicates stupidly, blows gas vapor, exhaust, or anything other than cool air into an engine. If i was worried about weight I would remove the 40lb bag of tools in my trunk. Or the spare, or the jack...

 

just so you guys no i went to inspection today. but there is good news and bad.

the good news is

the egr comes up as not supported and the rear o2 sensor came up as ready..... in NJ your aloud 2 not readiness codes. my car had 0. so the egr fix will pass. the rear o2 will pass. and nothing was questionable.

the bad news
the machine to hook the car up for the sticker was down as it is connected to the state when they make the sticker or some junk. sigh. so i got to go back. but at least we now know the car/cars with these mods will pass emissions.

now that i know all this i am wondering if all the evap stuff and the other things you guys are doing will also slip by..... i do not know but i do want to find out. i just dont want to do all the work and then either get a cel or 3 or more not readiness checks. and then have to re install it all. so here is what im going to do. im going to get the sticker 1st. then ill do the evap mods and whatever else there is. ill then go back and put the car on that scanner and see what it says.

 

thats great information.

What did you wind up doing for the EGR, did you disable Periphery 2 or did you leave everything plugged in?

What did it show for EVAP test?

 

The egr is all plugged in still. I did the preiphery2 only.

The evap stuff I dident do yet. I sad ill i would after I get the sticker.

 

yea I know you didn't do the EVAP stuff yet but im wondering what the scan showed.

I think disabling the Periphery 2 also disable EVAP test.
Also, even if you have the EGR still in, I think having the Per #2 disabled would act the same wether EGR was there or not.

 

well since i have unlimited access to the scanner i can do a few tests.

so your saying if i remove the egr and unplug everything ''egr related'' i should still see no cel?? and if i remove all the evap stuff and unplug it i should see no cel stuff?? also the readiness tests. plugged in to unplugged might show a fail/pass....

 

From what I understand if you disable the periphery #2 it disables all EGR related stuff and maybe EVAP stuff also.

If this is true, then it wont matter what EGR or EVAP stuff is either there or not there, it should show the same thing.

Also your saying that it came up as not supported when they tested it - which is different from not ready??

If you can have 2 not ready, how many not supported can you have, lol?

 

not supported is different then not ready in the readiness tests. . you can have the hole car as not supported and still pass. its not based off of 1 car or what 1 type of car and what it has... some cars have egr some dont. and so on. so if i am right there is just a obd2 list that applys to all cars. when they hook it up to the scanner you either have it or you dont. if you do it is ran through a readiness test. if you dont have it its not supported.

 

very cool, so turning off perhiphery 2, makes the scanner think the car does not even have EGR. Nice.

 

I have my MA inspection next month. I might turn off periphery 2 and see if it passes. worst case i turn it back on and get it reinspected for free. the print out will tell me the state of all the checks too.

 

ok guys. i got to inspection and she passed no problems. i got a 2010 m7 sticker so im good for 2 years.

fyi
i asked about the not readiness codes. my car had 0 but he said 2003 is only aloud 1 not readniss code. i did not ask the cut off year from 2 to 1 but hey. we are all 03 and up anyway. good luck to the rest of you.

 

I removed the EVAP canister and equipment today. Capped the small vapor line, and fed the large one into the solenoid, with the other end open. Left the solenoid pugged in. No CEL.

I used a longer 12mm bolt, and a dsm fuel rail spacer to get clearance, and bolted it to the frame rail. The end of the solenoid that plugs into the canister/filter, is still wide open and facing up.

Felt great to remove a bunch of hideous garbage from the back of my car.

 

interesting stuff

 

I turned the EGR off and got inspected. Unfortunately this wasn't an emissions year (every other year in MA) so i didn't get checked but i was told as long as i have no CEL i am fine. Either way the EGR is coming out when the intake mani gets pulled.

 

so my understanding after hours of reading everything
You can remove EVAP and EGR CEL Lights IF
- you remove EGR valve system completely
-and the EVAP system completely
-AND get a TUNE to make inspection ODB think your car doesn't have EGR or EVAP systems

AM i right?

Im in NY trying to get inspection, and i get Not ready for EGR valve and EVAP

I know my EGR valve is bad anyway, since im pinging at high RPMs, so ill just take it off.
Then ill see if turbo trix can do it
