Its purely a tuning factor.
Have your tuner do the right thing of using a proper closed loop routine and you'll see some decent fuel usage. Some tuning shops (noone in particular) only do open loop tuning which in a perfect world does not do a street car any justice as an everyday ride. It could also come back to the age old question if Autronic have a closed loop feature at all.. |

If you want economy like a std car then leave it std. Be realistic a motec or Autronic are built and developed for motorsport not toodling down to the shops

thats pathetic, indeed it maybe the tune but i just dont see why changing to a "better" ecu will ruin the fuel economy of a car this bad! i was happy to loose some fuel economy but loosing over 100km to a tank is alot...

a flash just uses the OEM settings as a base so it already has has the info were as a pnp ECU needs more attention as your basically starting from scratch. Fuel has nothing to do with the actually ECU itself just the time spent on the tune and the way you drive it. If you don't like it get it retuned better or sell it, simple.

Isnt this the one you bought off CREX on Rexnet for $1200del
if so in his description it states: "this ecu can pretty much do any thing anti lag launch control flat shifting map tune so no afm rotatale idle closed loop boost it also has autotune where you set where you want your fuel targets and the ecu will tune its self to the best possible power and torque. last time i used this ecu i picked up close to 18kw over the haltech i was using . its a top of the line ecu and one of the only after market ecus that can compare with the motec m800 retails for around $3650 fitted and tuned price drop $1200 posted " Just get your tuner to set the fuel goals properly!

i paid 1200 + posting.. cause i got it overnight bag... and i had to pay 600 for the knock board AND i had to get it "unlocked"
so all up its cost me nearly a new one... but yes thats the one also had to get some areas modified as the previous owner was running dual fuel pumps

I wasn't disputing the cost of it I'm just simply pointing
out that the ECU has the function to give as much fuel economy as you like/choose. If you want to unload the knock board let me know.
