    switch type TPS + single cam sensor

    So did you check it with a timing light while cranking? Note it should be conected to an analog input, not digital right? Since it is a switch you will also have to set your error high to 5.0 and error low to 0.0 for it to work.

    PClink software on a Vi-pec unit

    Yes it is recommended to use the latest G4+ software and install the latest G4+ firmware. There are a few reports of this lagging problem floating around but we havent got to the bottom of it yet. Mostly we have had it reported with fairly modern/powerful laptops using intel graphics and USB3 but havent been able to reproduce it in house. Some users have claimed improvements by installing the oldest Intel driver they can find, others have said changing to a USB2 port fixed it.

    You are right the odd TPS reading wont stop it from running. The voltage on analog 2 is sitting near zero volts so that may suggest there is a wiring problem (or is it still a switch type?). Trigger looks like it is happy. Did you check the base timing with a timing light? With 1 tooth per TDC mode you have to rotate the distributor to adjust the base timing. Otherwise, to make broad fueling changes in modelled mode I normally just adjust the engine capacity setting rather than mess with the VE table. Make big changes like +/-50% normally gives you a good clue whether your issue is fuel related or elsewhere.
  5. I suspect you will need a very small control range for that type of effect, try 50RPM. I would also suggest you turn off the hard limit to stop it interfering as you experiment with settings. This is normal, a lambda probe measures oxygen content. If you cut fuel or ignition then there is no combustion so your engine is just pumping oxygen down the exhaust.

    Link Extreme replacing Megasquirt

    Trigger 1 is the primary sensor (usually crank), Trigger 2 is the sync sensor (cam), so yes these are your CPK+ & CMP+. The pins labelled "Gnd out" and "Sheild/Gnd", are both sensor grounds and can be used interchangeably. Typically for triggers we splice the sheilds and the two trigger grounds together and connect them all to the shield/gnd pin that is right next to the trigger pins. As for the trigger offset question, the "reference tooth" that the offset is measured from is the tooth that comes immediately after the gap. So if the centre of your gap is 81.5BTDC then the reference tooth is probably about 71.5BTDC. This would translate to a trigger offset of -71.5 in Link language. Or possibly 360deg later (288.5) depending when your cam tooth passes the sensor. Im not sure what limitations the MS had in terms of gap position but with Link there is no limitation, you can have it wherever you like. However it is generally best to have the gap outside of the area your spark normally occurs (say 0-40BTDC) as when there is no tooth there the ECU has slightly less info to predict engine position as accurately.

    We dont do complete looms sorry. I dont know of any UK vendors doing 1JZ looms but there may well be some. 3 Vendors that I do know that offer them: https://www.wiringspecialties.com/1junwihapr.html http://panicwire.com/ https://www.boomslang.com/link-g4.php
  8. Most of it looks ballpark ok. The main setting that is not correct is the frequency on Aux 6, most ford valves like about 120Hz.

    Atom to run ignition on classic motor

    Yes, sounds logical to me. You are correct that the ignition map will likely be quite different between carburettors and injection so no point wasting time fully mapping ign for the carbs.

    Different Shift Light RPM on gears on older ECU

    I dont see any reason why 5 outputs connected to the same lamp wouldnt work, but there are possibly easier options. I think you could get just one aux do 3 or 4 different gear RPM thresholds using virtual auxes. Or, if you have a speed sensor connected so the ECU can calculate gear then you could just use a PWM 3D table, RPM Vs Gear to do it.

    switch type TPS + single cam sensor

    Yes 1 tooth per TDC would be the best mode for this set up. Make sure trigger 2 sync mode is set to none after that change. With 1 tooth per TDC mode you will need lots of dwell at cranking speed. Set the dwell table like my example below. Also lower your trigger 1 arming threshold to match example below. Can you make those changes then confirm you have a realistic RPM displayed and a spark when cranking.

    How to wired up Link G4+ Atom 2 on 3RZFE

    Do you have the spark edge set to "falling" in the ignition setup menu?

    I've moved your post to the G1 section. Does it only disconnect with the engine running or will it disconnect after a short time regardless of engine running or not?
