Why Illinois customers mail in mail-in pcm / ecu unlock or clone

Illinois has roughly 10.5 million registered vehicles, and trucks, SUVs & imports make up much of what Chicago-area shops and owners mail us. Mail-In PCM / ECU Unlock or Clone is a bench job most Chicago shops don't keep equipment for, so owners and trade shops across Illinois ship it to a specialist. Cross-region north — about 2 days each way.

What we see from the Midwest

Swap and race builds across the Midwest run on used PCMs that arrive locked to another car; unlocking or cloning them on the bench is faster than chasing a dealer, and the module is back in a few days.

Is there a mail-in pcm / ecu unlock or clone shop in Chicago I should use instead?

What does the $250 include?
The bench read, the unlock / IMMO-OFF / checksum / clone you asked for, verification, the prepaid inbound label and the return of your module. Return shipping is chosen and paid at checkout.
Do I need to send my original file?
No — we read the module itself. If the online calculator rejected a file you already have, a copy on a USB stick helps us see what was tried, but it is optional.
