They are not the same.
If my memory serves me right, an extender chip must be used with a MAF translator+. The extender allows the computer to recognize air flow in excess of 256 grams/second, which is the limit on the stock maf/chip, up to 512 grams/second. This allows the computer to continue to use the MAF reading to help control air fuel ratio at high airflow. I believe the maf translator+ has the capability to adjust your fuel curve and timing curves.
A maxeffort is a chip with a thumbwheel, and allows you to adjust various tuning parameters, some on the fly, others while stopped. Parameters include low, mid and high end fueling, and timing. Maxeffort is an OPEN LOOP chip, and it is designed for 1/4 mile racing, however many people use them on the street. This chip has a fair amount of flexibility, perhaps a little too much for the casual user IMHO, but makes good power.
Hope this helps.
