  1. Engine off, key on. I've sorted it now by doing the fans how I prefer doing them!
  2. Using this video: https://vdoubleyou-scott.tinytake.com/sf/Mzc0NTYwXzIxMjE0NTU (Thanks!) The fan works well on PWM, but for some reason, still runs with engine off...
  3. Out of interest, would this work with a straight on/off output or do you have to use a GP PWM output? Any examples of setup? We tend to use aftermarket fans and go with a simple on-off relay, but have got a fairly stock car here at the moment that I'm setting up with stock fan controller.
  4. Hi Guys, Anybody using onboard knock on an ST205/MR2 plugin G4+? Having a few issues with it not actually picking up anything at all on a customer's car. He wired the Knock sensor himself but I've checked and it is correct. Interestingly the pinout info in the help file does not show a Knock Input, but Link's Tech dept confirmed the pins are as per stock. Cheers
  5. Just to add... We've seen this a few times now and had to convert to aftermarket trigger wheels. On stock triggers we were getting false RPM readings when we looked at logs - as crazy as a 10,000rpm jump in 2/1000 of a second!!! MGT Motorsport in the UK sell a kit that converts to a "Crank" trigger (36 teeth IIRC) and a single tooth "ref" signal on cam. Works a treat
  6. Interesting... Having it in the return seems wrong to me as by then the fuel has been to the rail and back, however, I assume that all fuel in the tank would have "mixed" properly and this isn't an issue. Probably overthinking it...
  7. Hi, If you have twin fuel lines, do you think you should use twin Ethanol Sensors when using bio fuel or Ethanol? Can you get any Ethanol sensors that have AN fittings rather than push on tails?
  8. Hi I get asked this regularly - "I've got two identical ports on my (Xtreme / Thunder etc) - which one is CAN and which one is the PC port?" Now, one of them has an orange o-ring on it (which might get lost), so that helps... But I'd love to see either a different connector on one, or at least a label / engraving...
  9. We are doing something similar. There is apparently a similar trigger already in the presets... Hopefully Simon will recall which one it is as I've forgotten!
  10. Out of interest... How did you get on with tuning this? I'm just doing one now - wondering how the base map supplied worked out with regards to VVT operation and the turbo...? Did you alter the VVT settings much?
  11. There is a way around the 0.5 step John. I can show you. Same for ignition table... If the error is not much the idle table doesn't do much... Numbers that are too big or too small can also cause it to hunt.
  12. The options for idle control specific to eThrottle are open loop or closed loop. Open loop should be the one you try first. Or just bring it over and we will sort it as agreed
  13. Thanks for the input. After using HPA in the past, decided to sign them up for that...
  14. Hi Guys, Here's one for you... If you wanted to train up a new employee and get them the basics of engine tuning without spending hours with them first...Would you sign them up to HP Academy or EFI University? Both seem good and personally I like the HPA seminars etc. Any opinions?
  15. See attached logs - one with closed loop and one with open loop. TTPlugInIdle.llg TTPlugInIdleCL.llg
  16. I spotted that in the Idle Ignition table just now Scott... Interestingly, the "0" degrees in the "0" Column is what is in the base map supplied by Link
  17. Yep - will grab one tomorrow
  18. Hi Guys, We've recently done another TT plugin and having some idle control issues... Set as open or closed loop EThrottle, we get a lot of hunting around the target idle. It's like a pendulum and the amount it swings, or if indeed it swings at all sometimes, is not consistent. Idle is set at 900RPM and it swings wildly from 700 to 1200. Sometimes as you slow the car down to a stop the engine stalls. I've spent about 5 hours on it now and it's driving me mad! Can anybody spot an obvious mistake (or many mistakes)?

    Sorry - I misunderstood what you said. So on the G4 pin 73 was AN Volt 1. On G4+ it is AN Volt 8. Thank you.
  20. I believe so yes - they should all be fed by 12v Ign rather than battery. The Fan Relay has perm 12v on pin 30 IIRC. Will check tomorrow. Would a different type of relay help?
  21. Grant Baker


    So we need to move that pin then to AN Volt 8?
  22. Hi We have an Xtreme wire in running a fairly normal 4cyl engine. All fine - runs well and everything works as it should... until we turn off the ignition switch. At this point the main relay and fan relays start pulsing away like mad. Off-On-Off-On etc. If we disconnect the battery and reconnect they have stopped, until we turn off the engine next time, at which point it happens again. It seems to be related to the ECU install as it didn't happen before on stock ECU, but can't see what is up. An pointers?

    Interesting. On my G4 plug in (EVO 4-8) I had AN Volt 1 as Oil pressure and AN Volt 2 as MAP sensor. I've upgraded to the G4+ and MAP is showing correctly (I have kept the external sensor). What is AN Volt 1 now showing me then? I have done no wiring changes.
