There are many varied opinions regarding the comparison of different EMS products. So instead of providing my biased remarks on how Crome compares to other systems, I will instead provide a price break down and it's up to you the user to decide which is most capable for your needs. All prices are suggested retail prices in US Dollars. The following systems do not include the price of a wide-band oxygen sensor and a laptop which are both necessary equipment to tune a vehicle for yourself. As with Crome, Hondata, and Überdata, the prices do not include that of ECU chipping.
