  1. I asked this question in the wrong forum so asking it here as well. I've currently got a Supra Link plug-in in my 94 Supra and am wanting to upgrade to an ECU that does full traction control. I like the features of the new G4+ Fury and are wondering if the ECU pin outs for the G4+ Fury are the same as the Vi-Pec i88 (not the plug-in) which was the other option I'm considering? If so, then perhaps I could use the boomslang adapter harness that they make for the Vi-Pec i88 for the JDM Supra with the G4+ Fury instead. Do you think this would work? Also are all the motorsport features enabled by default on the G4+ Fury, as I've read elsewhere?

  3. I'm keen on using full traction control as well. I have a 94 Supra and looking at the Supra JZA80 chassis, I see it has 48 teeth for the ABS sensor which would require 2000hz support to work up to 300kmh. As the Vi-Pec/Link only supports up to 500hz, are there any plans to upgrade the hardware to support more than 500hz? If not, are there other options than installing custom triggers with 12 teeth (to stay under 500hz) for the rear and front wheel inputs to the traction control software you are developing?
  4. I've used up all the aux outputs on my Link G4 2JZGTE plugin ECU and I need at least one more. I see that the 2JZ ISCV uses 4 aux outputs, so reducing this number would free up some outputs. Is it possible to change to and control the idle on a 2JZGTE by using a late model Subaru 3 wire ISC as these only require one aux output?   Â

    Just tried to start the car from cold and it started on the 2nd crank, so very pleased with the 5D crank fuel settings.

    Just tried starting the car on E85 (displaying E82) and it started on the second crank from cold. Very pleased now. Â The 5D fuel table with RPM on one axis (0 to 500) and the ethanol percentage (0 to 100) on the other has allowed for much improved cranking fuel values.

    I've just had another look at my 5D fuel map and I now see that you can set RPM on the X-Axis and Ethanol percentage on the Y-axis. I don't know why I didn't see this before, but this will allow me to add cranking fuel based on Ethanol percentage from 0% to 100% by adding more fuel below 500rpm only. I'll give this a go later tonight.

    I can't figure out how to use an rpm seting to turn the dual fuel table on/off. I've looked at all the activation options and none of them have rpm in the list. Can you tell me how to do that?

    Yes, I found the same that once it had started even for a few seconds, it was then much easier to start again even at low temps and high ethanol percentages. By what percentage did you increase the cranking fuel for E85 at say 10 degrees?

    I've setup a 4D fuel map with ECT (-20 to 90) on one axis and Ethanol percentage (0-100) on the other. This allows injecting a bigger percentage of ethanol fuel as the ethanol percentage increases when cold starting vs hot starting. This should simulate having extra crank enrichment for ethanol when its cold (which it needs) and it is working well so far.  As ethanol does not vaporize very well at low temparatures (compared to gasoline) you need to add a significant increase in the amount of fuel injected for cold starting when running high ethanol percentages such as E85.
