I installed my Blackwing and performed an Idle Relearn today. When I went to drive it afterwards it pinged at WOT. I since I driven it over 90 miles and the pinging is almost all gone now but I have a different sound now. It sounds like it is coming from the right rear wheel area. It happens right at the 1-2 shift and it is hard to describe the sound. It a loud rubbing like sound, almost like something is slipping. It does not sound like the tire is breaking loose to me, it only last for about a half a second and it does not happen all the time. Do the run flats make a funny sound when they break loose?

I have not heard of any issues like that. I have the blackwing and no issues. And I have burned the Runflats a few times with none of the noise you are describing. Sorry! I would take it in and have it checked.

 

Does the problem go away if you switch back to the stock intake?

 

I guess that I need to take it to the dealer, it makes the the with or without. Sounds kinda of like a quick fan noise.

 

How do you guys like the Blackwing?
I'm thinking of doing an intake mod before I take ol' Blue Thunder out of winter storage.

 

it's a great mod! Installs like stock, and looks almost like it belongs there. you won't be sorry!:cheers:

 

Hey Guys - Was the idle relearn necessary w/ Blackwing install ?

 

Waltzc5, I just reconnected the battery when I finished my install. Seems like it works fine for me. I think most people have said just driving it will allow the PCM to relearn on its own. :seeya

 

Planning on getting the blackwing in two weeks...how do you like it so far? Was it very hard to install? How long did it take you from start to finish? I just paited my radiator shroud and would like to keep from putting any scratches in it.... :smash: :smash: :smash:

 

los7783, I really like the Blackwing. I wasn't interested in cutting the shroud - i.e. Vortex, and I'd guess you aren't either with the new paint. I also didn't really like the looks of the Vortex.
The install was very simple, it should take about 1/2 hour. The Tech Tips section has a very good step by step. Two things which would have made it much easier 1) The stock airbox needs to be forced off the mounting studs with a fair amount of pressure, more than it would seem was safe. 2) If you have an '01/'02 the rubber coupler that comes attached to the Blackwing needs to be removed first, and the other one that comes tightly wrapped put in its place.
The car feels stronger all across the throttle range. I'm not a race car driver by any means, but I feel it was a worthwhile mod. It also sounds cool when it is sucking air.
Good luck. :seeya

 

I picked up 15rwhp with my Blackwing and that was only driving 50 miles for the re-learn, usually best to get 150-200 miles. We had a dyno day, I did one pull took the car off the dyno installed the BW and then drove around 50 miles and did another pull. I like mine.

I did the relearn just because that is what I thought I should do. It pinged badly at WOT near the 1-2 shift point. I have put over 120 miles on the car since then and the ping have gone away. I still get that noise out of the right rear, my friend says the tire is breaking loose. It is not a loud bark but more of a muffled hum noise. I know that sounds stupid but it is hard to describe. The car is fast and sounds great from the front and rear, I also have the A&A exhaust mod.

 

Rocketrider2,

When you say you drove 50 miles for the re-learn, do you mean that you didn't do the battery disconnect and then drive around?

 

Yea...what exactly is this relearn thing everyone is talking about...as I stated earlier...I plan on installing one soon and want to find out as much as possible before I get it...

 

[QUOTE] I still get that noise out of the right rear, my friend says the tire is breaking loose. [QUOTE]

I would also be concerned that only one tire is breaking loose. What are you running in the rear for oil? Have you added any more additive then specified in the manual?

 

Hey vettenuts - how do I get in touch with the RI vette club?
Do ya's have a web site?

Thanks...from just over the border (Seekonk).:)

 

Here it is:

BTW, the Blackwing rules!

============================
(You can substitute pulling fuses instead of disconnecting the battery. Sorry, but I'm not sure which specific fuses, but I think there are two you'll need to pull.)

LS1 Idle Learn Prcedure (from How to Understand, Service and Modify Corvette Fuel Injection and Electronic Engine Management by the late Charles O. Probst)

Here's how you help the computer relearn the minum throttle angle:

(First, disconnect the battery)

Automatic Transmission LS1

1. Turn the key off, reconnect the battery, turn the AC control off, set the parking brake, and block the drive wheels.

2. Start the engine, shift to drive, let the engine idle for five minutes.

3. Turn the AC control on (make sure the AC button light is on). Idle for another five minutes.

4. Leave AC on, shift into park, and idle for yet another five minutes.

5. Turn the AC off, and idle for a final five minutes.

6. Finally, turn the engine off for at least 30 seconds.

Manual Transmission LS1

1. Turn the key off, reconnect the battery, turn the AC control off, set the parking brake, and block the drive wheels.

2. With the transmission in neutral, start the engine.

3. Turn the AC control on (make sure the AC button light is on), and idle for five minutes.

4. Turn the AC off, and idle for another five minutes.

5. Turn the engine off for at least 30 seconds.

 

I disconnected the battery during the install of the Blackwing and then reconnected it. Then I performed the relearn by turning the key on and pulled the two fuses, put them back in, started the engine and let it idle up to 175 degrees and then 5 minutes more. The I drove it about 50 miles.

As far as the rear end, it is just as it came from the dealer, bought new with less than 10 miles on it.

 

Thanks for the info!!!

 

Allen,

Shot you an e-mail with club link as well as one for the caravan.
