HP Tuners - Can you do this!!

Cleaned my TB, well needs to be relearn... so what's the process.. i have dig and dig and dig.. and I cant find it.. unless i'm blind..

Although I know for a fact that the dealership scanner can do it.. so why not this software...???????????

[IDRIVEAG8GT]

Huh? Whaddya mean your TB needs to be relearned? Does it set a code or what?

[cmt_cibarra]

Well... it's not the TB it's the TPS... that needs to be relearned.. since I took it off and cleaned and it's not idling... no cam, no thing special.. just a stock TB...lt headers, maf tuning.. worked fine until i did the cleaning on the TB..

[IDRIVEAG8GT]

That's very strange. Are you sure you plugged it back in? It shouldn't need to be relearned, I can almost guarantee. Look for vacuum leaks, make sure the TB bolts are tight, and make sure your plumbing is all tight.

[IDRIVEAG8GT]

Is this the same car in the other thread?

[edcmat-l1]

Something else is wrong. No need to relearn anything after taking the T-body off and then back on.

[cmt_cibarra]

Yeah it's the same car.. although I wanted to put this thread as is title to see if HP tuners will actually respond to it.. so that then actually use it as feedback to provide other items in their software...

Sounds like it doesnt need to be done. So why add something thats useless? sounds like YOU messed something up.

Easy chief. We're working on it.

[PSYKOSTEVO]

possible that you saturated a sensor in the TB or something?

remember, TB cleaner has lubricants that are not good for sensors, and likewise carb cleaner has solvents that are bad for them. I usually try to take the easy sensors out and mask off any that are a pain with blue painters tape as cleanly as possible.

There is a procedure for this and Snap On has it available on their scanner to do it in about a minute. I had a 2009 1500 5.3L that I cleaned a throttle body on and it idle fine right after backed it out of the shop fine. Road tested and pulled back into the lot put it in park and the idle was 2000 rpm didn't matter what I did with the pedal. Eventually it threw a code for idle speed to high. I grabbed the scanner and performed the idle air relearn and bingo problem solved. The pic is for a 2007 Vette. You could try leaving the battery disconnected overnight and see if it will clear what is learned.

PSYKOSTEVO... sensor is very incased with metal... so I really doubt that..

Flame... try it out and no joy....

we use idle relearn a lot at the dealer,, anytime the throttle is cleaned or the ecm is re-programmed,,, without doing it you can have lots of idle issues

[carlrx7]

weird, i pulled my friends 2010 corvette tb off, then everything else to change his cam, swapped out the cam and put everything back on, loaded stock tune and it started right up, idled a little high (1000) for the first 10-20 seconds, then a perfect 650...

there is a learning function to correct the throttle as it becomes dirty. I will add the learning reset function to the scanner.

this feature would be awesome i had this issues after cleaning a throttle body for a customer, and on some trucks the only way to relearn was to take it to the dealer and pay them $100 to do it, i actually tried the manual relearn process posted above and it does work on some models, but on other it seem like it took forever to relearn the idle,...... i have seen them do it at the dealer and it took longer for them to get the tech2 out and connected than it took to get the procedure done

After reflash, turn the car onto accy mode only for 30 seconds without touching the gas pedal. This will give the ECM a chance to calibrate where the fully closed position is. Turn the accessory mode off and start the car. Run it for Another 30 seconds until the car finds idle and shut it off. Restart and you should be fine. This worked for me.

Chris@HPTuners

Thank you Chris so much, for your response.. we will be looking for it in the feature...

[cmt_cibarra]

TTZ06vette

I would try that out tonight...

[cmt_cibarra]

TTZ06Vette

NO such luck..... but I did reflash it and just to verify it did had the same values of the IDLE.... so I believe my ECM is good.. but if you know a way to find out if my ECM is good? please let me know.. because if I replace the pedal and it does not work.. the last item to do is to change out the ecm....
