Is it a Toyota 6 wire ISCV.? Have you supplied ignition switched live on the other 2 pins.? 

Yes, I have hooked up all 6 pins, 2x 12V+ and the ISCV gets warm when I switch to "ON" position.

Note also those aux runtimes that you show in your screenshot will always show "off", they only show on for basic on/off type functions like fuel pumps/fans etc.

A couple of other notes;

Your base position table doesnt have suitable numbers in it - copy the base position table from the supra base map will be a closer starting point.  Same with the max and min clamp - copy from the supra map.

You dont have ECU hold power set up so the stepper motor wont be able to reset/home after key-off, so in idle settings you will need to set it to reset at key on - and make sure you give it 5 seconds to reset after you turn the key on and before you start cranking. 

Will try those, thanks.

Hi all,

 

I am using an Altezzalink on 1JZ-GTE VVTI, trying to get ISCV to work, but there's no indication that it's working at all, I have attached my tune file, is there I'm something missing?  I have wired it to AUX5-AUX8

I have attached my tune file, any assistance is much appreciated.

Thanks.

[Altezza link Aux Inj outputs]

All of the plug-in ECU's only have 6 injector drives.  Although there are pins on the processor for the inj 7 & 8 functions, there is in fact no drivers or other conditioning electronics for inj 7/8 on the board.  Only on specific applications that need more IO or some other special reason for more injector drives then drives for inj 7/8 will be added to the separate adapter board for that application.  Since Link dont currently make a plug-in ecu for a car with more than 6 cylinders in most cases they are not needed.

 

Yes that would be fine.  Although most people in a performance application wouldnt even want to keep the narrowband sensors anyhow.  If you are fitting a wideband that can do anything the narrowband could do and doesnt need a heater control aux. 

Great answers, thanks for clearing everything up.

 

Thanks.

Inj 7 & 8 and Ign 8 are not connected on this ECU.

Hi Adamw,

 

Thanks for that, a little baffled why it's not since it's wouldn't add much more cost to producing the ECU, since the smarts are there already.

 

So my aim will be moving O2 sensor heater off Injector 5 to something else, am I correct in saying any one of the AUX output will be fine, set it as O2 Sensor heater and copy the settings over from Inj 5?

 

Thanks.

The altezzalink pinout in the help file shows inj5 & inj6 as O2 sensor heater & second o2 sensor heater if fitted to the vehicle. Pin O3 & Q11.

Hi CJ, thanks for that!  

 

What about Inj 7 and 8?  The specs shows this ECU should be cable of 8/8 Ign and Inj drivers.

 

Thanks.

Hi,

 

Trying to wire up the 1JZ-GTE VVTI to Altezza link.

I am trying to wire 2 additional injectors to the ECU, I see Inj 5 pinout is used by O2 sensor, inj 6 pinout is missing, same goes for inj 7.

 

What pinouts should i use to wire up additional injectors, and are they a "High resistance load"?

 

Thanks

I'll give this a try and will report back if required.

 

Many thanks,  much appreciate your expertise.

My apologies,

 

CAN DIG #1 State toggles fine with both engine on or off.

Thanks

Hi, in Aux Virtual monitoring, the snow button will toggle Virtual AUX no problem when engine is off, but once engine is running the Virtual AUX will be stuck to on.

 

[Altezza link snow button]

Hi,

 

I have set everything up accordingly (I used Virtual AUX2), but the input will remain "ON" when I monitor virtual Aux 2 with the F12 key, no matter what I do with the Snow Button.

Snow Button is "working" as I toggle the button the dashboard will toggle the light on / off.

Could the logic be incorrect some how?

 

Thanks

 

[Altezza link snow button]

Awesome, thanks!

Hi there,

I'm quite new to this, my apologies in advance.

I've tried to search for answers but unable to find anything.

My question is - the Altezzalink can communicate with the "SNOW" button via CAN / BEAN.  How do I utilise this in PCLink?  My scenario would be using the SNOW button to toggle features such as anti-lag or launch control.

Thanks.

 

[G4+ changing sub board]

Hi, I have a vehicle specific G4+ Plug-in, for the RX7

Now the vehicle is sold, i would like to use the ECU on my MR2 instead, is there a way for me to purchase just the sub-board / baseboard and switch it out?  It'll be a lot easier than trying to patch an RX7 loom to a MR2 loom.

 

Cheers.

 

[RX7 ISC control]

Hi Adamw

 

Thanks for your help, much appreciated!

 

Cheers.

[RX7 ISC control]

Hi,

In the help file it says ISC idle control will require Auxiliary channels 5,6,7 and 8 to set to ISC.

But those channels are used for the Oil Metering Pump.

I'm getting idle hunting issues unless I set the bunch of cells to the same ignition and fueling values.

Does this mean the Link G4+ plugin is not capable of controlling both idle and the OMP at the same time?

Also, how can I tell of OMP is really working with the G4+?  The outputs are constantly saying "off" in Runtime values.

 

Thanks.
