EF3 computer recalibrate (1 Viewer)

Jun 19, 2015
My '88 FJ62 has been idling slightly higher than normal and the acceleration seemed kind of off. The engine has 270K on it with a complete top end job done by ACC about 3 years ago. I experimented by swapping out computer modules with a salvaged unit I had laying around. Happy to say there was a significant improvement in the overall performance. The idle is smooth and there was more power to the acceleration. Before I do anything with the original unit, are these computer modules able to be recalibrated and who would I send it to?

Thanks, Steve
