You need to calibrate your MAF. Due to the much larger MAF housing, the ECU is getting incorrect information about the amount of air flowing in.
You will also need to tune for the larger turbo. There is no way you can run these mods without a proper tune.

You did everything correctly by providing the necessary data to the calibration team. Support for your calibration will be added in 1-2 business days. There are a lot of different ECU types and versions for each Mazda model and while we support most of them out the box, some are new or not seen to u...

Letters O and I are not allowed in VINs, it's always zero and one. VersaTuner website will check the VIN when you type it.
But if you make a mistake, just contact our support and we will correct the VIN for you.

There's not much we can do. Those devices constantly query the ECU and interfere with the flash process. They will interfere with any tuning solution you decide to use. You don't need to completely remove them. Just disconnect them from power or from the CAN bus for 1 hour while you reflash the ECU.

Then you probably have some other device connected to the CAN bus or the OBD-II port of the vehicle. Gauges, loggers, alarms, modules that keep the lights or radio on. Common culprits are devices made by MX-5 Things.
You will need to disconnect them temporarily while you are reflashing the ECU.

What car do you have? Do you currently have an aftermarket tune on the ECU? Does it fail right away or somewhere in the middle?

This error can mean one of two things: 1. The ECU is stuck in some weird state after the last reflash. Try disconnecting the battery for a few minutes to reset it and then try again. 2. The ECU was tuned previously with a tuning solution that locks it on a deep level. It has not been tuned with Vers...

You can try.

It will not. EcuTek locks the ECU on many levels and needs to be removed before any other tuning solution can be installed. Try contacting the company that originally tuned the ECU or a Mazda MX-5 tuning specialist, such as Fab9 Tuning.
