Is there a gpec2 / 2a / 3 / 4 / 4lm pcm clone (mail-in) shop in Chicago I should use instead?
Most Chicago shops don't keep the bench equipment for gpec2 / 2a / 3 / 4 / 4lm pcm clone (mail-in) — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-region north — about 2 days each way.
Does Illinois vehicle inspection or emissions testing affect this service?
Illinois requires emissions testing in the Chicago and Metro-East St. Louis areas; downstate counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Illinois and federal requirements.
Do I need to send a donor module?
Yes. Cloning requires both your original PCM and a matching donor PCM (same part family). We read the original and write the donor.
What if my original PCM is dead?
If it is partially readable we can usually still recover the VIN + immo data. If it is completely dead we will tell you before any work and refund if the clone cannot be completed.
