Does anyone know anything about these chips? I have a 3rd gen lx and I would like to do some upgrades but I have no idea if this will even work for my car or if they work at all. Any input on these is greatly appreciated and if you have any tips on tuning the 89 lx I would be extremely grateful. thanks to all in advance.

 

As a general rule "chips" don't do anything for the performance of your car with the exception that they help to drain your wallet faster. One proviso; chipping a car which came from the factory with a turbocharger typically yields significant performance improvements.
