California FAQ

Common questions from customers shipping from California.

How long does shipping take from California to your Arlington TX workshop?
USPS Priority Mail from Los Angeles, CA reaches our Arlington workshop in about 2-3 business days. USPS Priority routes west through the Southwest network; usually 2-3 days given the distance. We start work the same day your module arrives and typically ship back next business day at the return speed you chose at checkout.

Do you accept gm ecm/pcm cloning (e-series) modules from California?
Yes — we receive modules from Los Angeles, San Francisco Bay Area, San Diego, Sacramento and the rest of California regularly. With about 31 million registered vehicles statewide, European luxury (BMW, Mercedes, Audi) are the bulk of what we see from California.
Is there a gm ecm/pcm cloning (e-series) shop in Los Angeles I should use instead?
Most Los Angeles shops don't keep the bench equipment for gm ecm/pcm cloning (e-series) — 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-country west — about 2-3 days each way.
Does California vehicle inspection or emissions testing affect this service?
California requires a biennial Smog Check emissions inspection in most counties through the BAR program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all California and federal requirements.
How is this different from your supply-a-part programmed ECM or Global A unlock?
Our supply-a-part service sources the module for you and programs a replacement; this clone service copies YOUR existing module's identity onto a donor you provide. The Global A unlock service opens a controller for tuning — cloning is not a tune and does not add power. Tell us your situation and we'll point you to the right one.
Will this add power or delete the immobilizer?
No. This is an identity clone only — it carries your VIN, calibration, and anti-theft relationship onto a matching donor so it's plug-and-play. It does not tune the engine, add power, delete or bypass the immobilizer, or modify emissions equipment. It also does not program keys.
