6.6L Duramax ECM
Repair Service
We rebuild your own engine computer at component level and send it back running - with every bit of your factory programming still on it. You are not receiving a replacement ECM. You send us your own unit, we repair it, and the same unit comes back to you. Most units are repaired and shipped back within 1 business day of arriving, occasionally 2, counted from the day your unit reaches our bench. Lifetime limited warranty on the repair we perform. Zero programming needed on reinstall because your VIN, calibration, immobilizer data, TAC data and injector flow rates never leave the board. Return shipping back to you is included on whichever service reaches you fastest. Fits 6.6L Duramax 2007-2010 Silverado, Sierra, 2500HD and 3500HD, plus Kodiak, TopKick, Express and Savana diesel applications. Several part numbers were used across this platform and we run a separate listing for each - match the number printed on your unit to the number in the item specifics above before ordering.

Read this first - you are buying a repair, not a part
You are not receiving a replacement ECM. You send us your own unit, we repair it, and the same unit comes back to you. If you wanted to buy a working computer outright, this is not that listing.
SymptomsWhat we fix
Crank, no startEngine turns over but never fires
No communicationScan tool cannot reach the ECM at all
Injector driver failureThe single most common failure on this ECMP0201-P0208
Internal processor faultsThe module reporting its own failureP0606 P0601 P0602
Stalling and random shutdownDies while driving, restarts like nothing happened
Completely dead unitNo power up, no response, no signs of life
These boards fail in a handful of predictable ways - heat-cycled solder joints, blown injector drivers, tired power supply components. We repair at component level and bench test under load, not just for power-up.
The advantageYour programming never leaves the board
This is your original ECM going back into your truck. VIN, calibration, immobilizer data, TAC data and injector flow rates all stay exactly as they were. Which means:
Not neededNo programming
Not neededNo VIN coding
Not neededNo relearn
Not neededNo dealer visit
It bolts back in and the truck runs. That is the whole reason to repair yours instead of buying a replacement that has to be flashed.
The processHow it works
01PurchaseWe send you the return address right away.
02Ship it to usBuyer pays shipping to us. Pack it well.
03We repair and testBench tested before it goes back in the box.
04It ships back freeOn whichever service reaches you fastest.
Turnaround: most units are repaired and shipped back within 1 business day of arriving, occasionally 2. That clock starts when your unit reaches our bench - not when you check out.
Optional upgradesTruck down? Two ways to jump the line
Standard turnaround covers most people. If you need it sooner, pick one of these - not both.
Option AExpress Return$60Upgrades the shipping only. Your unit moves through the bench in normal order - it just gets home faster once it is done.
Option B - FastestRush Repair + Overnight$100Your unit goes to the front of the bench queue and ships back overnight. The fastest we can turn a unit around.
One upgrade covering both - do not add the $60 on top. Overnight return is already included.
Want either one? Message us before you ship your unit and we will set it up.
WarrantyLifetime limited warranty on the repair we perform
If the repair we did fails, we stand behind it. It covers our work - not a new unrelated failure, physical or water damage, a wiring or injector fault elsewhere in the truck, or improper installation.
PricingIf your unit needs more than a standard repair
Most units are a standard repair - you pay the listing price and nothing else. If one comes in worse than expected, we stop, contact you, and quote you first. Nothing extra is ever charged without your approval.
You approve the quote
We complete the repair. No bench fee.
You decline the quote
We keep a $100 bench fee, refund the rest, ship your unit back free.
The unit cannot be repaired
We keep a $100 bench fee, refund the rest, ship your unit back free.
The bench fee applies only when a repair is not completed. It covers teardown, diagnosis and bench time already spent on your unit. You never pay it on a completed repair.

ImportantBefore you pull the ECM - read this
A shorted injector can take out a driver on a freshly repaired ECM in minutes. If you are chasing injector circuit codes, have the harness and injectors checked before you reinstall. Message us - we will walk through what your codes point to.
ShippingGetting it here and back

Not sure it is your ECM?
Message us through eBay with your VIN, your codes, or a photo of the label. We would rather answer a fitment question up front than have you order the wrong service.
