The hardware is rarely the problem unless you chance used parts or something.eldabo said:... My reason is that there are a lot of companys out there that have done the reserch To know what works and what dosn't.
They will all work, just depends how much you know about what is not working correctly or to its potential.
Tuning is where the "works or doesn't" comes into play.
You can buy a $3000 ECU and still run like crap if you don't understand how it EXACTLY works.
Some do make it easy to plug-n-play but of course that costs more or you can take it somewhere and have them enter the numbers for you.
There are always driveability issues etc that only you can tune for.
I run GM ECM and have my struggles learning it for the past several years. Its no 10 sec ride but it runs good and clean.
what ever you end up going with, learn about how it all functions together.
Putting a bunch of parts on, wiring them together and hoping for the best does not work with FI.
It will be up to you in the end to make it run right.

You should be able to change parameters to compensate for E85. In the GM stuff you can but I don't know how well the aftermarket units handle it.
