in a similar vein to another thread, how can you tell if Vvti is working on a 3sge blacktop running a power fc? ive had these ecu's before but not with Vvti, any info would be good. thanks |

Practical test = Unplug the solenoids and take it for a drive. Will feel very flat, esp around 5krpm. Just make sure you turn the car off before you plug them back in again. From memory Power FC only has a check for o2 and knock. So wont go into limp mode. Or if you have the software, i dont think there is a vvt-i on/off option in there, but you could zero the entire tables for both inlet and exhaust. Obviously making sure you back up the original values before doing so. |

theres only so much you can do with the commander, but it is possible to make adjustments with it. Check out http://www.fc-datalogit.co.nz if you are looking for the software/interface. yes his is turbocharged with very large aftermarket camshafts. vvt-i active on camshafts that big is very bad for valve to piston clearance. faker- you should join up to VIP status and you'll find alot more information available to you about his impressive build, and lots more! |

Guys, Sorry to highjack the thread since we are on the topic of Power FC. I am going to do the auto conversion to manual. I was wondering should I invest in standalone Power FC. I checked Japan website it is about USD 1K. I heard it can do wonders and all the parameter of a stock ECU can be changed according to local condition and driver preference. Can it remove the speed cut as well? Pls let me know as i am still contemplating. |

yeah, no speed cut, you can set rev limit with handcontroller easily etc ive tested mine back to back with the stock ecu -as we know theres not a lot of grunt with these cars obviously, but the tuned ecu is much better imo. cheers |

Thanks RS200faker Yeah I heard the power Fc can certainly help the low end torque issue. I find the original ECU is very restrictive maybe due to emission control and it is also tuned for 100 Ron fuel. I think by retuning with local condition and fuel rating ... we can get the most out of the engne.. Anyway thanks for your input....appreciated.... |

yes thats right, stock ecu tunes tend not to have performance as their main aim in regards to ign timing and afr's. part throttle/cruise fuel economy can improve with a good tune as well. cheers |
