Ordered 2 from GM Parts for $20 more then the dealer had 1

Part Number for my 09 was 12589380 if anyone else needs one. ($58 from GM Parts)

 

I think mine is going out as well.

 

Are you getting a oscillating AFR during cruise as well?? misfire's on 3/4??

 

Yep.

 

LAME! Go GM....

22K on my odo, how many on yours Term?? Gestapo?

 

13K on my car.

 

Well I think I maybe joining this club.... my car is running like warmed over ****. Keep reflashing idles rough, throws a rich bank 1 on idle code, and MAF codes. Even though it's been tuned to basically perfect MAF.

Sooo... who knows... I did however manage to pop ANOTHER weld on a Synapse intercooler! FML

 

Leaking IC will cause codes like that. Get the IC fixed and send me a copy of the file you are running and a log.

 

Morgan is sending me a new intercooler, so I can put this **** to bed. It's been over a month since my car has run right for any period of time.

Yeah, I'll let ya know Dave whats going on... I'm just soo pissed at it I want to drive it off a cliff.

 

That sucks ass!

 

I have not had any cracks in my Synapse IC..... Knocks on wood. Maybe yours was just a bad one.

 

tell me about it... I have 2 intercoolers on the way. one is going on the car the other will be sold...

I'll let you all know what is going on with it!

And honestly I have not heard it from anyone else either... But it has done it 3 times now.

 

I was running up to 30 psi with the MBC for a while too.

 

I did the pill mod for 2 weeks about 28psi and that is when it happened....

 

I want to see a log of your car doing some 60-100 mph pulls in 3rd. I want to see how quick it is compared to mine.

 

Should be the same since you run the same tune and make the same numbers, no??

 

my tune is different from his now... I have taken his map and made it my own with some slight changes here and there... more low and mid range timing, dal changes, now his MAF table is what I am running 100% spot on... other than that I don't load anyone's map directly and use it on my car.

 

Interesting....

 

don't see whats so interesting....

 

Your not knocking on more lowend timing? 10-11* around 3000-3500 is all my car can stand.

 

nah, no knock... I did get some at WOT so I richened it up (it is getting colder here now) and took out a degree of top end timing...

But all of that is a mood point... right now I am on a stock map, stock maf and a broken intercooler! So its slow as dogs **** with ZERO boost!

 

Always take out spark dont richen it to get rid of knock.

 

Any chance we'll see a dyno plot of these numbers??

 

You forget that the air is less dense here normally. Drive your car down here and see how that warm Florida air slows it down.

 

Im just going by what YOU wrote to me... Same tune, same mods, same exact whp numbers right??
