Sorry to interupt the existing topic.
I have a friend whom is currently using a Honda CIVIC D17 BOT, boosting at 0.5bar with stock 240cc injectors. Well, wideband indicates that the A/F lean even though injectors tuned up to 90% with Dynojet Power Commander.
There are a few question here, sifuz... Please help.
1) He bought a set of Mitsubishi GSR 390cc injectors to be installed into the car. However, GSR injectors are low impedence injectors and resistor pack is required. But on the other hand, some ppl say by using Power Commander, resistor pack can be ignored. Please help.
2) According to his foreman, the engine fuel rail has no return line to the fuel tank. How is that possible? :hmmmm: :hmmmm: :hmmmm: Please guide.
3) He also mentioned that the D17 ECU has the intelligence to retune the timing and AFR. Which is why E-manage cannot be used. In order to use E-manage(blue), the car battery have to unplug from time to time to reset the ECU to default.
My personal question on E-manage blue applied on D17/VTEC, Can the ignition timing be controlled.
Thanks all the VTECS Sifuz in advance
