Chech Engine Light On P219A P119E P0171
Check engine light on this week codes p219A, P119E, and P0171. All something to do with air-fuel ratio imbalance. Found out there is a calibration update for my ECM at the dealer. My ECM is currently flashed to run E85 using the EcuTek. My question is do I have to flash my ECM back to stock let them update the ECM? If yes, will I still be able to flash it back with no problem? Thank

exhaust leak , stuffed 02 dirty maf sensor , or you changed your intake and it thrown the maf sensor calibration off. If your ecutek tuned the dealer is locked out and will not be able to flash an update to your ecu unless you flash back stock tune first, then when dealer flashes you will loose your ecutek licience. Your tuner may have already allpied the latest rom calid when they did the tune or they should be avle to do the rom ecu calid update for you. but i think your problem is hardware and not related to an ecu calibration update. Or you running a petrol tune on e85 or an e85 tune on petrol, have you selected correct map ? if your on a map switch tune or your flex fuel sensor is not working correctly |

I'm pretty sure because the ecu is sort of locked or something with ecutek because some sort of encryption takes place with the rom that's loaded into the ECU, that's one of the reason I chose the openflash tablet. You'll need to flash back to stock otherwise the dealer might have issues or blame the problem on the fact the ecu was tampered with because techstream will fail to flash to your ecu, you'll also want to make sure you do it when your completely out of e85 and switch back over to 93 pump gas and drive around for a bit with that.

When you write a stock tune back to ecu with ecutek the access to ecu is retured to normal and anyone can read\write, but if dealer or you overwrite the stock ecutek rom with another tune system you will overwrite the embedded ecutek licience info in an unused part of rom. Then ecutek wont write, you need to get ecutek tuner to reissue your licience. |
