On a heavily tuned car the MAF sensor can run out of range and put the car into limp mode. We recalibrate the ECU to run without it.

What it is and when it makes sense

The mass air flow sensor measures how much air is going into the engine so the ECU can fuel it correctly. On a standard car it works well. On a heavily tuned car with a bigger turbo and intake, the air flow can go past what the sensor can measure, and the car drops into limp mode with fault codes.

A MAF delete recalibrates the ECU to work out the air flow another way, so the sensor is no longer needed. It is a tuning job, done on supported ECUs alongside the rest of the calibration.

On a standard car, a MAF fault usually means a dirty or failed sensor, a split intake pipe or an air leak, and we would fix that instead.

Good to know

Any change to your car’s software is a modification, so tell your insurer. We always diagnose first, and if a repair is the better answer for your car, we will say so.

HOW TO READ THIS

Each row is a control module we have a working solution for. The note tells you what typically also has to happen on the car, because where a part has to be unplugged that is mechanical work on the vehicle, not something a file alone can do.

We have more than one route to most of these jobs, so the requirements on your car are confirmed when we look at it rather than taken from this table. Treat the notes as what to expect, not as a fixed instruction.

Marked New means the solution is recent, so we check those individually before quoting.

Common questions

Do I need a MAF delete?

Usually only on a heavily modified car. If your car is standard and showing a MAF fault, it normally needs a new sensor or an air leak fixing.

Will it affect fuel economy?

Done properly, as part of the calibration, it should not. That is why we only do it on supported ECUs.

Can you check my car on the dyno afterwards?

Yes. We have our own dyno at the Maidstone workshop.
