Would not the reprogramming of the ECU pretty much reset the adaptive learning? It seems to also have wiped when I had an oil change due (doh). I swapped from a 93R to a 93S, then back to 93R, and did notice the slight idle/RPM change that happens for a split second when I put it in park before I turn the car off (doesn't seem to do that while in drive - the idle RPM changing when coming to a stop, and never did that the first time I pushed 93R to it).

Otherwise I understand - disconnect battery for few mins, and that will reset things - but seriously wouldn't applying a new tune account for that? (just curious!)

I actually have the same thing ahead of me (A firmware update to my SCT, and some new tunes sent that can only be used with the new firmware - same tunes w/ no extra mods, just 'updated'). I'm curious to hear how all this goes/causes of it?

 

Hey, OP!

Sorry to hear that you're not pleased with the new 91Race tune. I'm not sure what could've been changed in the tune, but I'd be happy to look into it for you. Is it only the idle and throttle response that are different? Have you had either of them to the track to compare times or anything?

I don't imagine much would've changed if all the mods are the same, but being that all our our tunes are hand-written, it's possible that one or more parameters were changed. Can you please shoot me a PM with your order number or email address, so that I can have our Lead Calibrator look into it for you. Let me know! Thanks for your patience and understanding.

Have a great weekend!

 

How do you do that?

Yes, it is only the idle and throttle response that feel different. I've never been to a track, so I can't compare times between the two. I will PM you my email address and the order number shortly. Thank you for taking the time to help me! You have a great weekend as well!

 

After you load a tune (or reconnect the battery), the computer has to learn the idle parameters again. Just start her up and don't touch any pedals. Let it idle for 10 minutes, then another 5 minutes with the A/C on. At that point the air/fuel ratio will stabilize and the adaptive learning will be reset.

 

[QUOTE=Antonio323;7916734]How do you do that?


Relearning the idle is pretty easy, simply follow the steps above and that should help your idle. As for the throttle response, I've set up our Lead Calibrator to examine your files to see if there's any changes that could be made to get it back to the way it was for you. Please let me know if you don't hear from them by Monday or Tuesday. Thanks again for your patience and understanding. Have a great rest of the weekend!

 

Well, I reloaded the old 91 Race tune yesterday and the car is just as good as it has ever been. I think I'll just stick with the old tune. Thanks so much for your help guys!

 

Disconnect the NEGATIVE battery cable for 20 minutes.

Be sure and recalibrate the gas pedal after rehooking the battery.
