Thread: zzp

when zzp says they can tune out you 0420,egr, and evap codes what does this mean and what will the advantages be?

IF you delete the EGR and EVAP when they delete the codes your SES light wont come on....

whats the 0420 code for?

no cat

hm,guess Ill be getting that tune instead of fixing my 02 sensor then lol

All it does is remove the code it still doesnt fix the fueling issue that blue was telling you about.

then screw that idea, but still getting that tune anyway, might as well, is there a difference between the 3800 tune and the zzp?

I have heard that the 3800 performance tune is better do to them using DHP instead of HPTuners. I guess DHP is better.

If you would bother to have read that thread like you were told, you would know that you keep the rear o2 in place and in the pcm have the CEL set to not illuminate and you will not get the issue with the car dumping fuel and you will not have a CEL do to not having a cat.

all i was asking about was if the tunes were different, i have a 3800 tune already, just asked, and I am fixing the 02 sensor so itll be fine. and what is CEL? sorry if you think thats a stupid question i just never had a car that i modified that had all these codes and computer crap.

Google

If you type in CEL you'll get your answer.

It's a tough world I know.

If you've never modded anything before why don't you research like I've told you a million times to?

because thats what this forums for isnt it? post a topic and get answeres from real people? or am i wrong?

Incorrect. Do a search first then if you can't do find anything ask. Being lazy isn't a excuse. When you have a car that's been out for as long as Grand Prixs the info must be present somewhere and a simple search will yield you the answer rather quickly. Now if it was a 2015 Concept car..then yes maybe the answers/questions won't be present for some time.

thanks for the "Help", and whos to say i did not try looking it up, but again , thanks for all your help...

guns, you need a cat in NJ, they do a visually look for it at inspection, last time i went they now have a camera in the floor they drive over, and can see the whole bottom of the car on a monitor.

if you get a hi flow cat, get the code deleted as its likely going to set the code anyway, but at least you have the cat to pass inspection.
