Hi guys was wondering if any1 has had this happen. On saturday i got my Black Bear tune, and on monday on my way back to work the CEL came on. It was on prior to tune, because I installed longtube headers a couple weeks before tune. I taught the tune was suppose to take care of the CEL. The light was off after tune but came back on. Let me know what you guys think.

 

2008 silverado 4.8 RCSB mods: GMPP CAI, Long tubes, Magnaflow exhaust, and BB tune.

 

That light concerns me, and also is an eye sore

I bet you have 2 Codes, and I bet they are P0134, and P0154. I'm probably right because those Longtube headers probably didn't have any places for the Upstream O2 sensors.

There are many things that can set off the CEL, without knowing what code has been stored in the computer, no one can even suggest what is wrong.

 

If you get a new ECM you need to do a crank position relearn which Justin takes care of for live tunes. I would find someone with a code scanner or go to AutoZone and find out what code is stored, then we can start helping you.

Just back from AutoZone and their reader wouldnt work......just kept saying reading on screen. Another guy was waiting for the reader after me, and they plugged it on his car and the reader worked pretty fast.

Sorry for the delayed response, Justin was delayed getting out of Dallas due to weather and didn't get home until last night. He checked your tune, and there was no reason to expect this code, however, looking up GMs calibration service, the P1133 and P1153 is common in the 08s. We have the calibration update here, and all you have to do is send your computer in, and Justin will get it sorted out for you.

 

You should have an email in your Inbox from Justin, he replied earlier today.

Thanks for the reply Jennabear, you guys are the best.

For the record guys. It wasn't the tune that made the CEL come on. Its a GM callibration update that needs to be installed. The headers didn't help, but CEL would have came on eventually even if the truck was stock. I recommend everyone get a black bear tune, its the best mod you can do to your vehicle. Thanks again Justin and all at Black Bear. Very happy customer

Best take-away from this experience - for anyone else reading this - is to ask your dealer *before your PCM is tuned* if your truck is due for any system updates. At least start with a clean slate.

Or get a spare set of computers with the latest updates.

      I thought I was building a HD 3500 srw, maybe I was lost.

      Which 2027 engine will you choose?

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.
