2013 Mustang 5.0 Dead after writing tune

[imsuperman]

Hey guys,

I think I might know the answer but I want to make sure this sounds right. I read out my SCT tune and wrote it back in with HP Tuners. Now the dash lights are going crazy and it won't start. The SCT handheld is saying incorrect vehicle now. Was I supposed to return to stock with the SCT before writing with HP? Is there anything I can reset or do I need to contact SCT in order for them to force the return to stock file to write? Thanks for the help.

Take off the neg. form battery for 30 minutes or so. Should help.

Ok, will try that thanks. Do I need to reflash again after 30 minutes? I also notice under OS there's an RPM Limit Patch. I did not apply this but not sure if SCT gives this option and was turned on in the tune.

So it appears to be an issue with copying the entire spark table from one strategy to another. And I'm not sure which one it is since there's a crap load of tables. And there's nothing in the software to tell you what would cause it.

You need to give a more clear explanation if you want help.

You said that you read out a tune and re-wrote it, bricking the car. Now you say that you have tried to push spark tables across strategies.

Check spark > Advance > Idle Spark Advance. I had problems with Derivative Gain, Proportional Gain/ N-D.
Also Borderline corrections.

Sorry, for some reason the first time it didn't work but after disconnecting battery and putting on charger the base tune went through ok. Then I did I copy of a tune I had running when the car was an Auto. My buddy now owns the car and he removed the Auto and had a manual installed with a different ECU. It has an SCT tune in it so I want to put back in the tune I wrote which is a lot better so I'm using the compare option and just selecting the categories I want and I narrowed it down to the spark table so far. Might be others but borderline worked but IDLE table doesn't. Is there anything in the software that can show me what's different between the strategies and not just the values?

you always have to return the SCT back to stock, do not stack tunes. different checksum's on both

swapping from auto to manual you will need to license a manual strategy and flash it to the car

Ok,thanks. It's been over a year since I've did any tuning and forgot all about it . I did have to use up 2 credits when writing the tune. I got pretty much everything copied over from my other tune except all of the spark tables. Having issues with IDLE and some others so I've been just manually copying and pasting from the tables and changing the column values to match as well. Here's the 2 strategies.

I noticed Flex Fuel has been added but I probably won't mess with those since it's no longer my car. Thanks for the help.
