Piggy Back Ecu And A Tune... More Power?

[NA power]

hi all

i am thinking of buyin a Piggy Back ECU for my r33gts25 and getting it tuned on a dyno. it seems to b running pritty rich, when its sitting there idling you can smell fuel. from a disstance away and i checked the plugs and they are black. So it has to b running rich.

Anyway done this? did you get a decent amount of power out of you engine by doing this??

or is it a waste of time on a NA car???

thanks for your help

I have a rb25de head on my rb30 . I use the stock rb25de ecu and an Apexi SAFC 2 . I also have an air fuel ratio gauge fitted . I have no trouble setting fuel mixture and get good fuel economy. Your engine shouldnt be running rich if its standard , check to see if your water temp sensor is working and sending a signal to the ecu . Unless you have done some modifications to your engine to increase performance , theres not much to be gained by fitting a piggy back ecu .

if the car is running rich (regaurdless of mods) you will gain power by adding a piggyback. i'd go for the afc neo over the safc2 as it has more adjustment points.

in a N/A is it worth getting a new ECU?? would it add power? i mean atlest 10kw or so, and with a hand controller for the fuel/air ratio, is it possible with them to just pump in loads of fuel, so u can get a sweet power gain?

Get an old e-manage blue, you'll see more power from playing with the timing as well as the fuel
