Injector & ignition pulse simulation
Power, ground, and load-circuit analysis

Important Note
Some vehicles with IMMO or PATS require key programming after installation. This is normal.

Dominic Gonzalez –
I recently purchased the 2020 Mercedes GLC350e ECM and was really impressed with how smoothly everything went. The ECU arrived VIN programmed and ready to go, which made installation super simple. They also offered free shipping, so I got it without any extra cost or hassle. Communication was great too—they kept me informed the whole time and answered my questions promptly.
