Not all ECU cloning jobs are straightforward. When Apex ECU worked on a 2000 Mitsubishi Galant 2.4L, we discovered an MR420679 engine control module containing two MH7203FA processors. Learn how we used PCMflash Module 31 and specialized bench programming to read, transfer, and verify the ECU data, and why understanding the module's architecture is essential for successful cloning.

The image illustrates the ECU cloning and programming process performed by Apex ECU.
Cloning a Mercedes ECU can look simple on the bench: read the original, write the donor, and send it back. This job showed why it is not always that straightforward. The customer’s original ECU had been affected by engine oil...
Yes. We successfully cloned a Mazda CX-30 PAJ8-18-881 Mitsubishi Electric ECU using Flex in Bench mode, and the replacement ECU was installed and confirmed working in the vehicle. Here's what we found and how we did it. Identifying the...
Most ECU cloning jobs sound simple from the outside. You read the original ECU, transfer the data to a replacement ECU, install it, and the vehicle is back on the road. This 2010 Jaguar and Land Rover Denso P5 ECU...
If you’ve used AI to diagnose a vehicle issue, you’ve probably seen this happen: You ask one question… Get a confident answer… Ask a follow-up… And suddenly the diagnosis shifts. Same car. Same symptoms. Different direction. That’s not random. And...
Most transmission control module jobs follow a predictable path. You read the original module, transfer the data to a replacement, install it, and the vehicle is back on the road. This one didn’t. We received a ZF 9HP48 TCM from...
A BMW DME swap seems straightforward. Install a replacement module, reconnect everything, and start the engine. Except the engine doesn’t start. The starter may crank. The dashboard lights come on. But the engine never fires. This situation is extremely common...
A customer walked in with a deceptively simple complaint: "The car won't start and the check engine light doesn't come on. But when we tried a replacement DME, the check engine light did come on… but it still wouldn't start."...
