    Wiring up 1jz vvti need help with a few bits

    link the ignition switched 12V wire to the MREL trigger. I wire the 1J vvti solenoid to the same power feed as the injectors

    G4+ Fury first tune 2gr-fe Turbo 92 MR2

    would pay to check the critical stuff like Crank and Cam sensors once you get it running with the build in scope, sounds like whoever made your loom isn't familiar with Toyota wiring diagrams and may have got everything backwards...

    G4+ Fury first tune 2gr-fe Turbo 92 MR2

    pin one is the left-most in the pics above, there's some more visual representations on this page: www.sq-engineering.com/tech-articles/coilpack-info-guide Looking from the wiring-side of the plug, from left to right it's - Ground, Trigger, Ignition Confirmation (not required), Ignition switched 12V, which matches the factory diagram snip you have there but doesn't match what you've typed about having +B red to the "right most part" of the connector

    G4+ Fury first tune 2gr-fe Turbo 92 MR2

    I use falling edge on Toyotas with that style of Denso COP, how are the coils wired?

    Sensor grounds should only run to the sensors, don't ground any spare sensor ground wires

    Panel mount for MXS Strada

    I made my own for a couple of dashes but the MXS is sitting on top of the panel, the next one I do will be fully recessed with AIM's remote button interface as the buttons are a bit of a pain to get at when mounted in place of the stock cluster These guys do a flush mount bezel with the button cutout: http://www.precision-metalcraft.com/product-page/aim-mxs-strada

    Idle setting for open loop and closed lopp

    If the idle is oscillating, I'd look to adjust your base ignition and fuel tables to stabilise it first
  9. TPS calibration in the Link is extremely easy, I'd adjust the throttle stop before doing something dodgey like drilling a hole in the blade. Close the idle valve and get the warm idle at the right rpm by adjusting the throttle stop, then you should have enough range of operation with your idle valve to deal with cold start and electrical load idle up/AC Once that is done you turn engine off, switch the ignition on, do a TPS calibration and save the map
  10. remove the additional wires from the CAN connector that goes to the ECU, so you only have the two CAN wires.

    the single 5V splits out in the loom to run to multiple sensors

    IAT Sensor Choice for turbo charged vehicles

    I'm currently using an IAT1-8 in my Subaru, have it mounted in the intercooler pipe just before the throttle body. I'm changing it to a T1 Race fast response sensor which will be mounted in one of the TGV delete ports, it's 1/16npt https://www.t1racedevelopment.com/product/t1-fast-at/

    AFR, actual vs logged

    Ground offset. check what voltage the ECU is reading on the analogue input compared to what the LM-1 should have on the output

    [UPDATE] PCLink (on hold)

    Yes, I used to get the same thing before I changed the power management settings. Check the power management settings of your USB controllers

    [UPDATE] PCLink (on hold)

    is that when the screen has gone off or does the tablet go to sleep? There's quite a few power management settings in Windows that could cause it to stop logging while the screen is off

    ECU afr not matching stand alone gaugue

    I grounded my LC1 to the engine block, ground offset is a massive pain with them

    ECU afr not matching stand alone gaugue

    I'd trust the ECU reading more than the gauge, a 1V span for your AFR is quite small and will be massively impacted by any ground offsets. When you connect to the LC2 with the laptop, how does the reading in the innovate software compare to what you're seeing in PClink?
  18. I've had it working on Windows 10 via USB with no issues, just followed the instructions in the 1st post. That was on the g4+ plugin in my daily driver and on another g4+ Xtreme. It didn't work on my G4+ Storm as that doesn't have the datastream mode required

    VVTi - link to TP% or MAP?

    I'm working through a new map for a turbo 1zz I've been tinkering with for many years. When I next get to the dyno I'll be trying a 4D fueling setup, with MPG for the main table, TPS for the 4D table, and TPS for the VVT table. Will be tuning the main fuel table with the VVT and 4D tables zero'd out, when the main table is done I'll then do the VVT and 4D tables after that. If that doesn't work out nicely I'll give it a go with TPS as the load axis for the main fuel table with a BAP/MAP XOver equation load source. Have had the turbo setup running for years with the VVT load set to TPS and Fuel table as MAP, but looking to make it a bit cleaner

    Questions about the capabilities of a WRX9+ G4+

    using a single tuned map you can easily have it range between 300-600hp, simply by leveraging Link's boost control. You don't need to be switching fuel and ignition maps for different power levels. What ECU does your tuner recommend?

    Question about IPW adder table

    you after the ID1300x or ID1300x2? I used the figures from ID/T1Race for a set of ID1300x2 with an xtreme and they work perfectly

    you need to check how you've got your ECU logging configured along with the mixture map configuration. Also keep in mind you have the math function available for single cell tuning by pressing the M key when a cell in the fuel table is selected
  23. JMP


    I'd avoid using the auto tune function if you're not using a dyno to progressively work through the map. On the street it will just make a mess of your map and it looks like you're already getting some very large steps in the fuel map around idle. Mixture map with decent filtering is a better solution for street tuning

    looks like you'll need to do some configuration of the knock control setup, you've got cylinders reading way over your knock target at idle. To add another row/column to any of the tuning tables, select the table and press X, then hit the green plus icon for the axis you want to add to and type in the value you want.

    I'd get it running and let it warm up, then adjust the master so the fueling is roughly right, then you can start the fuel map tuning. The 1zz turbo I'm currently working on has Deatschwerks 60lb injectors on the stock returnless fuel system and it needed a master of around 8ms for the idle cell values to be around 30 for a petrol AFR of 14.4 in traditional fuel mode
