Long story as short as I can give it.
Friend purchased a car with an ECU in it.
He then moved to a hill station and the car is running like shit and he reached out to me to help him fix it.
The ECU Map is password protected. The guy who sold him the car keeps giving him a password which does not work.
I was able to get the password protected map off the ecu after a herculean effort.
Software is ECU Manager. 1.14
https://www.haltech.com/downloads/software/#

Map I will upload
Non protected map you can get with ECU Manager. 1.14 samples folder.
I have tried comparing password protected to non protected and made little or no progress.

Do you think this can be cracked ?. Worth spending time on ?. Or best to just start with a fresh base map.
Problem is both the car and my friend are in a different city.
Say I try to remotelly load a map and it bombs there is no way for me to upload the old map without a password.
And that opens a whole can of worms.

As a start, have you contacted Haltech to see if they can help ?
They may have a back door for resetting lost passwords etc ..  people forget passwords all the time ..

Haltech have put up a notice on their web page which says. If its a sprint 500 ECU and your having problems. Hardware or software dont contact us. This is an obsolete product and we no longer support it. If you send it to us. We will return it unopened. I have tuned with pretty much every ECU brand out there. And no company is going to share a backdoor even if it exists.

Needless to say I am no a big fan of Haltech.

Car is and old 1.3 Suzuki Swift. With ITBs and a header. How does it matter here.
ECU = Sprint 500 as already mentioned.
Software = ECU Manager as already mentioned.
Map which is password protected already attached in original post.
 
It could be that the map was made on an earlier version of ecu-manager. But I do know the passwords are backward compatible.
I guess the owner may not even making a small token payment if it can be cracked. Cheaper than having to re-tune the car from scratch.
