|GM Calibration Programming Services - $85.00 per ECU|
|EFI Connection does offer GM calibration services (also known as TIS2WEB or TIS-SPS). These calibration services are also offered by your local GM service shop, with the exception that your local GM service shop will not flash or reflash a controller removed from the vehicle it was originally used with. You may choose or require this service for any of the following reasons...
- You purchased a brand new ECU (PCM, ECM, or TCM) and need a base calibration for your application.
- You want the latest GM calibration in your ECU to address any "bug fixes" before your tuner begins custom calibration work.
- Your tuning software requires two licenses for your ECU; one to work with a used ECU and a second to load a different calibration. We are currently aware that only HP Tuners requires two licenses to begin with a used ECU and load a different calibration. EFILive, for example, only requires one license per ECU, regardless of calibration.
- The ECU you have was removed from a used vehicle and needs a base calibration for the vehicle/engine type you are working with.
- New Gen IV ECMs (E40, E38, and E67), regardless of the vehicle type you specified at the part department counter, do not come from GM with a specific calibration and will require a base GM calibration for the vehicle/engine type you are working with. In other words, you can order a brand new E40 for a 2005 GTO, perform a full flash with a 2005 GTO calibration and the electronic throttle will not work.
- Used Gen IV ECMs (E40, E38, and E67) can be pulled from non-V8 vehicles, but require a base GM calibration for the vehicle/engine type you are working with. A "full flash" with EFILive, HP Tuners, etc. will not replace all calibration segments. In other words, you can pull a used E38 from a 2008 V6 Impala, perform a full flash with a 2008 Corvette calibration, and electronic throttle will not work.
- If you have a new or used Gen IV ECU (E40, E38, or E67), you will probably need a fresh GM flash that suits your application.
EFI Connection can reprogram your new or used ECU with the latest GM calibration for $85.00 per ECU...

- We will email you an invoice containing the details you provided.
- Ship to us your ECU to the address on the invoice, the provided invoice sent to your email, and contact information so that we can call you for payment.
|EFI Connection does not offer custom calibration services or "starter" tunes. A quality custom calibration requires a history of tuning experience with many different engine combinations and the use of an engine/chassis dyno.|
"Can I provide my engine specs (cubic inches, heads, cam, injector size) and get a starter calibration?"
|Tuning an engine controller requires the feedback from a wideband O2 sensor (to adjust fuel) and an engine/chassis dyno (to adjust spark). Without this equipment it is difficult (to impossible) to provide an appropriate calibration for a custom engine. However, professional tuners keep a tuning repository of engines they have previously tuned so that you can provide your engine specs and receive a calibration that is suited to run your engine. Tuning software does not simply accept input of engine specs and a resulting calibration suited toward your engine. Setting up a custom calibration requires manual adjustments to spark and fuel tables and other parameters suited for your specific application. Building this repository can take years of tuning experience. EFI Connection specializes in building engine harnesses and not custom tuning services. For the best results for your project, be sure to seek the services of an experienced tuner who has experience with both dyno and on-road tuning. Looking for a good tuner? Give us a call and we'll help you to find a reputable tuner.|
EFI Connection has tuning equipment for internal use only...
|EFI Connection specializes in engine harnesses, replacement GM engine harness connectors, and custom EFI solutions. We have chosen to exclude custom tuning from our scope of work to best focus on what we do best; build engine harnesses. Are you curious to know what we use for prototyping and tuning our own vehicles?
