cyborgsabah said:for a street car i personaly think that standalone ecu is a not very important.. why spending so much money when you can use cheaper alternative like e-manage or re-chiped stock ecu... with piggyback (not s-afc, it sucks), the stock ecu sure still can handle 1.8 bar what.. unless you want to go higher than that... use the money to buy something else like high cams, better fuel pump etc... but if got budget why not..

Force Performance said::shades_smile:Most aftermarket ECUs are open loop systems where estimates of fueling and ignition are made based on sensor input values to controls the peak pressure position to be in an optimum position. When you have that under control, you have also got the means to control your engine efficiency.

And only a handful run on open loop configuration. :regular_smile:

hybrid evo said:sifus, if i can only afford 1 item, either EMS or bigger turbo, which one should i get?
budget =rm3000
engine evo2(stainless steel i/c, wastegate, fuel regulator, metal gasket 1.5mm, vr4rs block, gtr r34 fuel pump). other parts all evo2 la
option a= standalone ecu (haltech or mircrotech)
option b=bigger turbo (ar70, ar80)
option c=e-manage and t04e (can get right with rm3000?)
so which one is the best? can i just use bigger turbo without EMS?
please help me. thank u
dolly said:i would keep your stock motor and turbo and go straight to microtech lt8. My old setup with microtech ecu went 290hp with 0.9bar stock standard everything. A few other efficiency mods would get you to your goal pretty easily. This was on a sissy evo3 bottom end, with your vr4 bottom i'm sure you'd go further!
