as long ad they completely control the air fuel and spark you can use the factory ecu to control all the other non horsepower stuff like an auto transmission and other bits. so they do work "along with".

You get what you pay for.

Not sure why anyone would look for the cheapest stuff to build horsepower with. It's a time bomb waiting to happen. Building cars isn't for someone that needs to cut corners. In the end you pay the price for not going down the right path.

so your saying don't buy used parts? dont look for deals? my garret was a waste of money? a Haltec sprint 500 on sale or used is a time bomb? im no newb to modding cars. thanks for your input...

You are talking about a Piggyback like the FIC and eManage, etc. Garm is correct...a standalone is a full replacement of the ECU and if not mistaken the ECM in some or all cases?

Not a piggy back a stand alone, stock ecu cannot be fooled, we have tried and aem is even stumped. All fuel air and spark sensors are hooked up and have complete control, but stock ecu stays in place to help with all other bits like trans shift points. Do some reading and it will come clear. 1.5 knows, as he put it using a standalone "inline".

I just don't know why you'd want to do that with an Echo, what is there to control that a standalone couldn't handle?

That type of thing is usually done for more expensive vehicles.
