  1. I had a similar problem when I bought a Continental sensor from Ebay, from supposedly a reliable seller and I paid good money for it, it ended up being a Chinese knockoff sensor, I ordered a real one from Summit Racing and have never had a problem since.

  2. You fill in the modeled fuel table numbers yourself, there are many variables to each engines VE that would not make sense for a one size fits all approach, you have a few idle tables that you can use to make idle afr changes as well as cold start settings, but the main fuel table is where most changes in fuel in general are made.

  3. That would be hard for me to swallow, I like to be able to make adjustments here and there when I get the car out, but I do understand why someone would want to, I guess "protect" what they consider intellectual work, although it wouldn't be all that hard to datalog the car on a dyno and fill in the blanks as to what the timing map and fuel map actually are anyway.

  4. In my experience a lot of the 4g63's do this, your likely in too high of a gear and are lugging the engine especially if you have aftermarket cams in it, I use overrun fuel cut as mentioned to make them stop doing that.

  5. Ive had the same issue and figured it was something backfeeding for some reason, I now realize that I do run the newer software and have since it first came out so it could be an update issue, I just turned off the hold on the ecu to stop it because my check engine light would stay on permanently though very dimly and the ecu would not ever power down if I let the ecu fully cycle the fuel pump relay, if I turned the key off before it shut off the fuel pump by itself, the ecu would power down properly after a few seconds and after moving the idle control motor, if I let it stay on after fuel pump prime then the idle control motor would never move after key off and as I said the ecu would never actually power down, it keeps the control relay powered with less than 12v, I think I measured around 5v on the relay keep alive coil.

    Unfortunately the knock pin is not connected on the VR4 ECU.  You cannot connect it to any other input, it needs to be to the dedicated knock input.  If you were willing and know someone that is reasonably capable with soldering I could give you some instructions on how to solder in a link wire to connect the knock pin to the knock input.  

    Could you share this information with me as well?

  7. I have a simple question, when using the dual fuel table, is the percentage the percentage of fuel table one that will be used or the percentage of fuel table two that will be used at say a certain ethanol level.  For example if I set the axis to ethanol percentage and I want to run fuel map one at 50% and up ethanol and I want to run fuel map two at 80% when ethanol content is 40% or less how would that look as far as the numbers.

    Hi guys,

     

    couple of questions

     

    when you take ur car to tuner , what does it mean when they lock the map?

    does that mean you can’t see the values or you can but can’t change it? It means that the tuner doesnt want you to steal his work that he did on your car and give it to your friends or sell it, that means that it becomes basically tamperproof.

     

     

    on link g4 plug in, can you have a switch for anti lag so it can be switched on and off? Yes you can have a switch to turn that function and many others on/off.

     

    does link g4 support fuel pressure and oil pressure sensor so it can stop the engine reving above 3k if oil or fuel pressure is low? Yes, that can be configured.

     

    finally, is there a wireless solution so you can see pc link on iphone to use as monitoring gauge? Im not sure on that, thats more of an app issue than a link feature I would think.

     

    What do i need to have an obd wired in?
