Hello
2015 C7 stingray z51
First time flashing a gen 5 LS ecm,
Made some changes to the stock file, flashed it, car wont idle or drive correctly, spark is unstable,
p0300 misfire codes, flash back to stock and all is well...
odd???
anyone else have this issue?
Fixed after re-reading stock file and re-editing it.
which version of software are you using?
Newest stable version, updated it last week, could be due to deactivating too many dtcs. Or not downloading the stock file after holding down the ignition button for 6 seconds to get the vehicle into true KOEO.Quote:

i always hold down the ignition key for 6 to 7 seconds to read file
My first question would be what changes are you making
Vehicle has long tubesQuote:

Haven?t had an issue now since i reflashed it to stock and then reread and made all the changed only to the dtcs that came active on their own and leaving the o2 feedback setting alone.
Thanks for this, i read it on another thread and it was the only way to flash entire due to timing out.Quote:

Does the car have one of those Pedal Controller units that plug into the gas pedal? These will cause all sorts of issues every time you flash a car. They must be removed when flashing.
Car is completely stock other than long tubes.Quote:
