My mechanic was telling me today that if I remove my egr, my engine will start nocking? What have you guys experienced from this? Is this true or not?
I also had a problem with my car nocking/misfiring around 3k rpms in most of the lower gears when accelerating about 35-40% or more. I switched to 89 octane (not the greatest with turbo) instead of 92 octane and it went away. I've been going back and fourth from 89 to 92 and haven't noticed the nock anymore.
Input??

Well, I removed my EGR system completely and my engine will knock down low (<2000rpm) under load, but I think it's because I'm running 10.5:1 compression with that damn AFX ECU and the 91 octane knock juice.

your megasquirt, my megasquirt, ehh, whats the difference anyways.
LMAO.......i couldnt help it, that makes me laugh. Right now Brian should rename the Megasquirt, "Coaster" since all it does is hold up his beer on the coffee table. lol
Who's turn is it to use the 2gnt squirt this month.....

I just wanted to clarify that this (this time) isnt a dig on driggs, but a general comment on what mrslick most likely did. Its not driggs fault (i hope) that after mrslick spent all the money sent to him for squirts that I happened to send him mine for updating, then driggs magically gets the squirt he paid for. Clarification.

Great. This topic is about EGR systems. I'm getting sick of seeing MrSlick MS drama trickle into threads all over the board. Please stay on topic.

The removal of the EGR system has such minimal affects on performance or engine operation (BANME!) that I dont think it could cause knock at idle or at WOT.

Can't even cause any problems at WOT cuz it's only open at idle.

right...I'm just saying...it seems like it would have more of potential to cause knock in place, rather than removed. In other words I don't see how removing an EGR system would cause knock...like what was claimed by the mechanic in the orginal post.

Then you need to read up on what the EGR system does!
The EGR sends uncombustable air back into the combustion chambers to decrease the combustion chamber temperatures. By doing so, it reduces NOx emissions. As far as I am concerned, though, fuck NOx

OIC...I was just thinking in terms of hot exhaust gas entering the chamber...thus rising the temps. I was under the assumption that the EGR system was strickly an emisions system. Obviously I didn't think that the gases were uncombustable and such...that makes sence though..thanx for setting me straight.

yeah I know it's not from the EGR. Do you have suggestions as to where a good place to get a catch can is. PM me or send a link so I can check it out. It's on my list of things to take care of. It's amazing how long that list is getting now!

there's several posts about catch cans, the subject flared up and got real popular for a week or so, now it's smoldering again. Basically you just want to put it in-line to the PCV valve.
