im wanting to run a lot of hp on my eclipse, I would really like to set the record for most hp on a 420a, which is why im rebuilding the motor to handle the turbo at high boost and the other mods like bigger injectors and other mods well im wondering which ecu or piggy back system i should get so that i can program what i need to when i need to easily.
 
I don't know if they make it for the 420a but I'd go with a vipec. Its what I'm tuning the evo with and its an absolutely amazing system.
 
Megasquirt is the best ECU they make for the 420A.

This will allow you to tune a wide variety of things. You also will need a wideband O2 gauge and Boost gauge.

Good Luck on your build! make 420A owners pround

much appreciated for the link, and what is the map sensor section on the link not sure which one i have, or need? As well as i plan to i would love to get the 420a over 850 hp.

The bar stands for barometer. From what I have read the standard 2.5 reads up to a certain level of boost and to get higher numbers a 4 BAR would be needed.

The world record with a 420a turbo is 661hp..

^ He is right. DSM Zero has the fastest 420A on the forums and even recorded I do belive
 
The Megasquirt products are not out of stock. You can still buy and use them today.
