Hi everyone,

Took the plunge and invested in a GAP IID tool. It arrived today from island 4x4 and is up and running. Wow...what a special bit of kit.

I’ve done some tinkering and I just can’t seem to find the menu for reading live injector data? I am wondering if it’s under a menu header I am not understanding. Any pointers much appreciated.

I've raised this with GAP previously regarding the injector values for my 5.0 SC and was told the standard 'we expose everything that is available'. I know this isn't correct as if you plug in an SDD it gives injector by injector values for mis-fires and I've seen it myself.

I do wish GAP would investigate queries a bit before cutting and pasting their standard replies.

Unfortunately for all the good reports GAP get about their customer service my experience hasn't supported that which is a shame as I agree it's a powerful and very convenient piece of kit

Thanks WB, I was expecting the GAP to be all I ever needed. So I am a tiny bit disappointed I can’t seem to read those values. Because I do think I have an issue. Drivers side bank rear injector ish. SDD...enlighten me? 2012 4.4 TDV8 Westminster - Baltic Blue, Jet interior

SDD is ‘Symptom Driven Diagnostics’ which is what LR dealers/specialists use to diagnose faults. It’s an OBD dongle which connects to a Windows laptop.It displays both live values and can also run diagnostic tests to check the function of things like fuel pumps, injectors and a whole load of other things.

There are very reasonably priced ‘clone’ OBD adapters although I’m not sure if the software is available to anyone who isnt a dealer/specialist.

So you can either investigate getting the software or pay / find a friendly specialist to check your injectors.

itd be handy if it allows you to pull the adaptive fuel trims, but am guessing it becomes harder to find that data Its actually a sport

Fuel trims are available on the IID - for my car they show up and handy to diagnose rich/lean issues.

what the sdd allows you to do is pull the fuel trims for every single rev range. makes it much easier to diagnose issues. Its actually a sport

I’ll look into the SDD route, for sure. But I don't really want to spend £££s more, additional to the price of the GAP last week. But we’ll see. We are talking RRs, after all.

I just want to see each injector value. I’ve a ticking noise from the drivers side rear bank and after reading and looking into Chevy Duramax V8 diesels an injector is a possible cause, and reading it’s value is a starting point. All the YouTube videos present the same type of noise. It ticks when warm and is rpm dependent. Maybe a trip to the MD in Alicante/Elche is in order. 2012 4.4 TDV8 Westminster - Baltic Blue, Jet interior

You can buy the dongle "Mongoose Pro" for around £33 its comes with software that only runs on windows 7. All of it is a copy and not legitimate in any way.

However it goes way beyond what others offer and if you want to dig deep into a problem its the only way.

You can get injector values own my 3.6 TDV8. You go to live values and select 'Injector 1', ''Injector 2', etc

I’ve spent a fair bit of time mining the live value menu and there is no option to read the injector values on the 4.4.

Unless someone can advise differently? 2012 4.4 TDV8 Westminster - Baltic Blue, Jet interior

Have you updated the GAP tool firmware/software to the latest version?

I got the device on Thursday and before using it I ensured it had the latest firmware. I’ll maybe drop them a line. 2012 4.4 TDV8 Westminster - Baltic Blue, Jet interior

Injector values are under F for fuel injectors on my 5.0 S/C...

Yes the pulse widths and mis-fire fields are there but the data for mis-fires at least on mine is wrong - have a look at yours Pete and we can compare?
