Piggy back : what´s the best one for a 172

[Eros]

I´m planning to install some cams on my 172 clio sport. Those cams were never tested on a standard ECU (remaped)... I´ll probably need a Piggy back.
I´ve read many threads on this but they were kinda confusing...

What´s the best piggy back for the F4R keeping the fbw throttle control.

Why anyone got the Apexi ? aren´t supposed to be good ?

the only piggy back ecu that i can think of is the smt6

What about the unichip ? All those piggy backs control fuel and the ingnition timing or they just control fuel?

Depend on the chip and what its been programmed to do.

Don't bother with the unichip though or any piggy back since the stock ECU can now be mapped by so many places so well.

I know the stock ECU can be remaped, but the cams I´m going to set up, are usually used on race cars with standalone management, they were never tested using stock ECU. Nobody is sure if those cams would work with just a remap. That´s why I´m asking about the piggy back.
I don´t want standalone management because I would loose the traction control.
So I think I have to go with the piggy back but I have no idea if any piggy back would work of one is better than the other for the clio.

Stock ECU is more capable at running cams that the puggy back unit will. Piggy back units won't help run an advanced cam as such any better (they are likly to be worse) than a remapped ECU.

It would have to be a very strong cam as such not to run on stock ECU mapped correctly.

I´ve heard the stock ecu can´t handle the overlap they have "MAP" issues or something like it...
If the stock ecu is more capable of running cams ... what are the piggy backs for ?

Depend what cam your running high long duration cams as such can cause problems for the ecu for the map sensor but a piggy back won't help in any way.

Piggy back is for when the stock ECU cannot be mapped or can be used for a cheap way of sorting the car if you turbo it as such.

the only issues i've heard of are with a certain catcams profile

issues about too much overlap ?

Yep. You are confused, and 9 replies later, non the wiser. lol
