Very effective way to tune your Nissan. Useful for cars from stock to 500+ hp.

Stupid simple way to handle changes to your OEM ECU. NO user adjustments. Somewhat expensive, very conservative tuning, has been used by a LOT of high horsepower Z31's.

Great tool for those with a decent understanding of tuning ecu's. **NOT** an easy/cheap alternative to Nistune or JWT.

==== Stand Alone ECU ====
This will never be a complete list. These are just one's I remember seeing on cars. If you have used any of these on a Z31 please contact [[http://z31.com/forum/profile.php?mode=viewprofile&u=4|Steve]]
