- We dispatch to your bay20-mile travel radius included around 4715 N Stahl Park; $2.50/mi round-trip beyond. You stay on your other jobs.
- Documented hand-offPre/post scan reports available on advance request. Itemized invoice. Net terms available for recurring partners.
Where we program modules.
Mobile module programming is dispatched from 4715 N Stahl Park in San Antonio to the whole ring of towns around it — the trip band decides whether a visit carries a travel charge, not whether we can do the work. Every town below gets the same OEM-authentic module programming: ECM, PCM, TCM, BCM, ABS, SRS, instrument cluster, and body controllers, plus variant coding, cloning, virginizing, and software corrections. Where a shop sits too far out for a sensible dispatch, remote J2534 module programming and mail-in bench service cover the gap. Town-by-town detail is on our service locations pages.
-
Inside the radius — no trip charge
Schertz · Selma · Universal City · Cibolo · Helotes · Converse · Leon Valley · Live Oak · Stone Oak · Alamo Heights
Schertz, Selma, Universal City, Cibolo, Helotes, Converse, Leon Valley, Live Oak, Stone Oak, and Alamo Heights are inside our included 20-mile travel radius, so trade dispatch carries no trip charge. Module programming in the bay, priced as the job alone.
-
Per-mile dispatch
Bulverde · Boerne · New Braunfels · Seguin · Floresville · Pleasanton · San Marcos
Bulverde, Boerne, New Braunfels, Seguin, Floresville, Pleasanton, and San Marcos are beyond our 20-mile included travel radius; a $2.50/mi round-trip charge applies. Still a routine dispatch for module programming, ADAS calibration, and key work — the mileage is itemized on the invoice.
-
Beyond — dispatch, remote, or mail-in
Castroville · Kerrville · Fredericksburg · Comfort · Bandera · Canyon Lake · Wimberley · Hondo · Devine · Jourdanton · Pearsall · Luling · Lockhart · Gonzales
Castroville, Kerrville, Fredericksburg, Comfort, Bandera, Canyon Lake, Wimberley, Hondo, Devine, Jourdanton, Pearsall, Luling, Lockhart, and Gonzales are beyond our 20-mile included travel radius; a $2.50/mi round-trip charge applies. At this distance most shops choose remote J2534 programming or mail-in bench service; mobile dispatch is available and quoted per mile.
-
Radius confirmed at booking
Marion · La Vernia · Spring Branch
The included 20-mile radius is measured by road from our shop; we confirm at booking whether a Marion, La Vernia, or Spring Branch address falls inside it or carries the $2.50/mi round-trip charge. Either way the module programming itself is the same job at the same rate.
PCM and ECM programming
Spot-On programs powertrain modules for the trade: OEM flash of a new PCM or ECM to current calibration after replacement, VIN write, and immobilizer relearn covering SKIM, PATS, VATS, NATS, and the European equivalents. A used or donor module is virginized back to a programmable state or cloned from the original, platform depending. Named specialties include Chrysler and Nissan PCM/ECM software corrections through wiTECH and CONSULT to clear a known software fault without swapping hardware, and GM AFM/DOD disable in the PCM after lifter and camshaft work.
You get it three ways. Mobile dispatch brings OEM software, security access, and battery support to your bay — the included 20-mile travel radius carries no trip charge, and beyond it a $2.50/mi round-trip charge applies. Remote J2534 sessions run over your pass-thru nationwide, and any job that has to come off the OBD port ships to our mail-in bench and returns programmed.
ABS module programming
Spot-On programs and codes ABS and ESC modules after replacement: flash the replacement to the correct OEM software level for the VIN, then variant-code it to the vehicle's option content so the network stops flagging a mismatch. A salvage ABS module comes off its donor already coded, so its identity has to be rewritten to the target — virginize-and-code where the OEM tooling supports it, or clone the original module's data into the donor on the bench where it does not. We confirm which route applies, and that part numbers match, before you buy the donor.
Delivery mirrors our other programming work. Where the manufacturer's routine runs over the OBD port we dispatch to your bay — included 20-mile travel radius, $2.50/mi round-trip beyond — or drive the session remotely over your J2534 pass-thru. Cloning, virginizing, and EEPROM work go mail-in bench, US and Canada. Post-replacement bleed and calibration routines are run through the OEM tooling as part of the visit.
Do you program modules for shops in Kerrville?
Yes. Kerrville shops get module programming three ways. Mobile dispatch is available and quoted per mile: Kerrville is beyond our 20-mile included travel radius, so a $2.50/mi round-trip charge applies on top of the programming. At that distance most shops choose remote J2534 programming instead — you connect a J2534 pass-thru to the vehicle, we drive the OEM session from San Antonio, and there is no trip charge at all. Bench-only jobs (EEPROM, cloning, virginizing, Mercedes ESL emulators) go mail-in. Same OEM software, same NASTF VSP access, whichever route you pick.
Is there a trip charge for module programming in Schertz, Cibolo, or Live Oak?
No. Schertz, Cibolo, Live Oak, Selma, Universal City, Helotes, Converse, Leon Valley, Stone Oak, and Alamo Heights are inside our included 20-mile travel radius, so trade dispatch carries no trip charge. You pay for the module programming itself. The radius is measured by road from 4715 N Stahl Park, which is why a few addresses on the edge — Marion, La Vernia, Spring Branch — get confirmed at booking rather than assumed. Call with the OEM, module, and codes and we will tell you the band before we roll.
Can you program a module remotely if my shop is outside San Antonio?
Yes, and for most shops past roughly the New Braunfels, Boerne, or Floresville line it is the better call. Remote J2534 module programming works anywhere in the US or Canada with a stable internet connection and a supported pass-thru (Autel Remote Expert and similar). ECM, PCM, TCM, BCM, ABS, SRS, cluster, and body-controller flashes, SCN coding, variant coding, and VW/Audi/Porsche SFD unlocks all run this way. Anything that has to come off the OBD port — cloning, EEPROM work, ESL emulators — ships to our bench and ships back programmed.
Can you program a replacement PCM or ECM for my shop?
Yes. Send us the OEM, model year, engine, and module part number, and we flash the replacement PCM or ECM to current calibration, write the VIN, and run the immobilizer relearn (SKIM, PATS, VATS, and the European equivalents). We also handle Chrysler and Nissan software corrections and GM AFM/DOD disable. Dispatch to your bay, remote J2534, or mail-in bench — whichever fits the platform.
Do you program ABS modules on dispatch or remotely?
Both. Where the manufacturer's programming and coding routine runs over the OBD port we dispatch to your bay or drive it remotely over your J2534 pass-thru. Where it does not — cloning, virginizing, or EEPROM work on a used ABS or ESC module — the unit goes on the bench, mailed in or handled on a dispatch visit. Same OEM tooling and NASTF VSP access either way.
