This man is correct. The UniChip is a piggy back ecu. Been around a long time. Used to be extremely popular in the states. Very popular in UAE right now. Limited as far as ability goes though, and can only be tuned by an Authorized dealer.
ProEFI EMS' are Standalone. Just like other top brands, AEM, Motec, Vipec...etc.. They all have the ability to completely control everything. However, that comes with a higher price tag. Motec usually being the most expensive.
ProEFI recently overcame the plug availability for the Lexus ISF, and that is why they have the plugs for the '09+, or will in the very near future. They have two units available, but have yet to get the chance to map out the CAN system of the Tacoma. Should be done when i get mjne back up and running... So there are still bugs, such as CEL's, until that time comes. Unless someone else can get it done before me.
The UCON, is an inline, and in most cases the most user friendly. Plug it in, and don't worry about it. It usually comes pretuned, pretty close to how it needs to be. Major plus.
Just, have to wait until the plugs are finalized and URD
has the ability to make them fit the '09+. It will happen, and most likely in the next few months.
In my opinion, the UCON is by far the best chose for you OP. Just keep your eyes peeled for its release for your year model.
