  1. that transition from 1500rpm to 2000rpm in low load must feel weird on the road. On E85 I'd be throwing it on the dyno to check what your torque is doing, hard to tell otherwise. Any EGT logging?

    It doesn't matter if you have an onboard map sensor or not, you can still use the 4ag's original map sensor, just wire it to a spare AN Volt input and assign it as a map sensor in the software, then if you have an onboard map sensor, disable that in the software. In my view, the importance of knock control comes down to how prone your engine is to knock on the common locally available fuel in addition to how well it is mapped. Eg, a Subaru EJ257 is a lot more prone to knock than a 10.3:1 compression 4age

    if you're going with an aftermarket ECU that can do knock control, you'll want to replace the stock Toyota 4ag sensor with something like a bosch donut sensor, it will be more reliable and give better readings than the single wire Toyota sensor

    x2 on knock control not being essential on a 4age with aftermarket ECU. Tuned correctly, they work just fine. I personally see more engines fitted with aftermarket ECU's capable of knock control, where it is not configured as it takes time and money to correctly configure which many people don't want to pay for.
  5. comes from the main ignition map
  6. some tablets support OTG functionality where you can use what is essentially a splitter cable to connect to both a charger and the ECU. Others have hacked tablets to hardwire the power supply straight to the PCB inside
  7. they're listed in the help file with the new version

    Surface pro

    yes, I've used Surface Pro's and the Surface laptops with pc link for a few years now, no issues apart from the usual pause/lag when pclink is initially opened
  9. if your pump still works with the fuel pump fuse removed, I'd be looking at any non-standard wiring in the car

    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
  11. grab a Honeywell or other decent brand sensor, make sure it's remote mounted from the engine and you shouldn't have any issues
  12. I'd be replacing the AEM sensor
  13. 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
  14. 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
