MAZDA MX5 TURBO ECU REMAP

Last week we had this stunning Mazda MX5 turbo on the rolling road. The MX-5’s first generation is recognisable by its pop-up headlights. These are great cars to drive and installing a turbo is a popular modification.

The owner of the car had a feeling as the car wasn’t fuelling correctly/ running as it should. We reversed the MX5 onto the rolling road and did a run. It was confirmed pretty quickly that the car had an issue.

With a few minor checks done it was decided that it was down to the remap that was already on the ecu. The car was running a Mega squirt aftermarket ecu having been previously mapped elsewhere. We are familiar with Mega Squirt and have tuned quite a few cars. You can see in the image below how lumpy the fuelling is. And it didn’t sound to great on the rolling road either.

After a couple of hours on the rolling road we had rescued the fuelling. We had also improved the fuelling and the MX5 Turbo was making great power. You can see the difference in the power and fuelling below. The air flow ratio curve is much smoother than before.

The Mazda MX5 turbo, the perfect car for a daily driver or track day beast 🙂
