HP Tuners GM E99 ECM Services (ZR1)

ZR1 Modified ECM Purchase
Purchase a brand new E99 ECM that is already upgraded for tuning. Make sure to include your VIN at checkout. This option is ideal if you need your vehicle up and running as quickly as possible. Remember, do NOT send us your ECM.

E99 ECM License for tuning: (10) Universal Credits (sold separately)

ZR1 E99 Upgrade Service
This option upgrades your original E99 ECM without having to trade it in or purchase a new one. This requires you to remove the original ECM from the vehicle and ship it to HP Tuners for servicing. Once upgraded, we’ll ship it back to you.

E99 ECM License for tuning: (10) Universal Credits (sold separately)
No need for an IMMO relearn, crank relearn, or to perform the “Replace ECM” function in VCM Scanner on the stock ECM as long as the ECM is returning to the same vehicle it came from.
