microtechs are well worth their money and more. i had one on my vl turbo and it never had a problem and never went out of tune as a lot of people may suggest.

the lastest versions, the LT series, laptop programmable, is what i will be using the the ca18. reason being they are more programmable than the previous hansdet only versions, MT series. can map a variety or mixture timing/boost/air fuel ratio/revs/fuel at once, just like the more expensive computers mentioned by other people. and i know a tunerthat will setup it up like factory, cold start, cruise and full load maps.

have seen then used on rotarties, skylines, supras, 200sx's (installed by myself), and they all work a charm.

go the Microtech for sure. the cost is always nice aswell to spend on other go fast goodies.

and for extra $$$ you can get a dash just like the legendary Motec's, the only other brand to offer this product.
