    Toyota 2zz VVTL-I

    you do run out of IO pretty quickly with a monsoon but you should just get there in a NA setup from your 6x Aux outputs you would use: VVT Solenoid VVL Solenoid ISC Solenoid Thermofan trigger Tachometer output Fuel pump trigger you wont have any spare to run Airon or a check engine light If it's currently wired to run off a stock 2zz ECU you will just need to bridge the EFI relay feed to the main relay trigger (+B to MREL) so the system energises when the ignition is on. For the VVT/VVL feed one side of the solenoids with ignition switched 12V and run the other side to the ECU Aux output's you have assigned. In my 2zz turbo swapped AE82 I run a G4+ Storm, in another 2zz supercharged AE82 I've done it runs a G4+ Extreme. I like to go with the Storms as a base level to provide enough IO to cater for any future requirements

    Sensor voltage rising over time

    grab a Honeywell or other decent brand sensor, make sure it's remote mounted from the engine and you shouldn't have any issues

    Sensor voltage rising over time

    I'd be replacing the AEM sensor

    Wiring Questions for Gracey

    Nitrous activation would likely go to one of the DI inputs, pressure switch could go to a spare DI or Volt input, all depends on what you have spare in your ECU configuration If you're connecting the innovate analogue output to the ECU, you would use one of the spare Volt inputs

    Altezza Rs200 - a few issues.

    injector size and characteristics are needed for the modelled fuel model to work well

    PC Link capabilities

    need a windows tablet for pclink, if you just want a display you can run realdash on an android tablet

    evo 4 issue cant figure out

    Nothing obvious in the log to me, it would be nice to see a log with AFR and fuel pressure. From the ECU statistics page it looks like this ECU has been in use for quite some time, so I'd be leaning towards more of a mechanical type issue, going back and checking the basics. I had a similar issue with a turbocharged 1zz many years ago, where it would hit what seemed to be a premature revlimit around the 4000rpm mark. For that one it was a trigger issue and I had to use the 1NZ trigger setting for it to work correctly

    evo 4 issue cant figure out

    -100 wastegate trim wont cause it to break up like that, will just operate at wastegate pressure instead of higher boost. When you're tuning boost control you should be going through all the tables, I can imagine the -100 trim in there is more of a safety net so those that are blindly going about tuning don't grenade an engine

    Afr Rich on electrical load

    To me I'd say the injector deadtime figures are not correct or you have a grounding issue. In your log you can see the deadtime spike when the voltage drops, when the deadtime spikes your engine slowly goes rich and then recovers to normal AFR after the voltage is back to ~14V. Looking at the deadtime table, in my opinion the figures are likely to be guestimates with a 0.1ms step per 1V from 12 to 14V instead of actual measured data. There is some Siemens data in the link help file you can reference, I'm not sure what the 880cc part number is but the Siemens 3105 look like they might be around 880cc at 3bar base pressure. In the link Data they have a 0.058ms deadtime step between 13 and 14V at 45psi base pressure, which seems more realistic When I'm dialing in/confirming deadtime I use a big DC power supply in place of the alternator and run the car from 11V through to 15V watching the AFR while keeping the engine in consistent load sites, if there is an AFR swing then the deadtime is adjusted to keep it consistent. This has worked quite well for me resulting in an excellent deadtime table and rock solid AFR's through the voltage range

    [UPDATE] PCLink (on hold)

    I'm not sure why you'd buy a different ecu with this lack of update being the reason... doesn't make any sense to me. I've got 4x G4+ ECU's across my cars and none have any issues in everyday operation that I'm desperate for an update.

    toyota 2zz ge engine trigger patern and vvtli

    I used the 2nz trigger settings and 1zz Cam control mode on the 2zz's I've done

    Base maps/ ignition timing

    Looks quite a bit more aggressive through the midrange at peak torque, but as others have posted it's difficult to comment without more information

    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...
