what are the advantages off piggy backing the ecu sorry for the silly question but i dont really know that much still learning any way heres a example:
i have a automatic Rb25det four door, 3" exhaust all the way thru coughcough no cat,FMIC,huge K&N pod filter,CAI + DIY heat shield for pod,runnin 7psi,split fire coil pack's and some
other stuff.
with the IMPUL r33 automatic ecu so if i take this out and use microtech LT10s ecu instead i will lose my shift points for automatic and aircon etc something like that anyway
so if i piggy back it with standard impul ecu i will still retain aircon and that?
will it be better that standard? any more info would be great before i go ahed with it guess it will help my fuel econ stop it from runing rich my mechanic said its runnin rich because im
pushing the limit on the IMPUL R33 Automatic ECU because the car can breath so much more air because off the stage1 mods i have noticed that it does not like to go to 10 psi hits
R & R so i left it at 7psi no flat spots aka lag so if i piggy back the IMPUL ecu with the aftermarket ecu then i should be able to sort out my A/F ratios etc.?
If you dont Know off the impul ecu here's a site that will let you know what it does ==> ==>"ABOUT THE IMPUL ECU click me" <== <==
here's the the type off car i got my ecu off
(actually it was SAU member i bought it off lucky if you can find one off these here's the link : ==> ==>"THE CAR THE ECU CAME FROM click me" <== <==
