I have a 93 Si with a 95GSR motor. The motor has PR3 pistons for 11.5 compression. Other than that the motor is stock with I/H/E. I am thinking about getting a chipped ECU. What type of ECUs will work with my motor? Which programs are best? JUN,Skunk2, etc.? How much HP gain is to be expected from this upgrade.

Thanks,

hard to asy which program will make the power, there so many different variations, Spoon is a good start, also are you using the stock intake manifold or SKunk2 manifold....

if stock only one choice P72 sotck or chipped, with skunk2, you can use p28, p08, p70, p91 all with a chip or p30, p61, all in stock form or chipped again

if interested i sell ecus and chips..check my website

 

you want something with more fuel lower vtec more redline. then do your timing manually.

 

Check the "ecu programming?" thread which is also in the Tech section, and make your choice.
