A buddy of mine saw this item on E-bay and we were wondering if it can truly make any of the promises they are indicating. Will these modules work with TPI motors from 1988 and 1989???
Maybe noone has heard of this item... I told my buddy he would be better off doing a proper tune, but we wanted to see if anyone had experiences with this product, and if it was worth the money???
From the description I would say it is a resistor that makes the temp sensor read colder. Can do the same thing yourself or just burn your own chip to make those changes. Not sure how milage will increase if additional fuel and less spark is being fooled into the mix.
Bit more power maybe (I doubt the HP #), but not the right way to get it.
Problem with those types of things is that it may read too cold if you have a lower T-stat installed and not go into closed loop control.
