No Injector Values for 8 Injectors, Can this be the cause of my Rich mixture code?
Hi Guys, I recently bought a 2016 f85 at auction, I’ve been carrying out repairs myself and I am enjoying working on this engine. I’ve been having a rich mixture across banks, and been trying to diagnose. I’ve changed air intake pipes, and MAFS, Smoke tested the Intake, New plugs and coils, still have the codes 118111 and 118011. Today with ISTA I found that there are no values added for all 8 injectors. could this be the cause of my issues? do I have to pull the injectors to get the code value or are there generic values I can type in to test the theory. I would appreciate advice from those more experienced.

If you have EU6 injectors you don't need to set values, they are all the same for them. You should be able to sight the P/N and set value on the injectors without removing them.
Nothing stops you from showing EU5 into EU6 slots tho, and that is a No Bueno. |

I appreciate the reply, Got my bore scope and had a look, all 215, For pig iron I coded them and deleted the engine faults, ran the car up to temp and Bang….codes came back. I changed out the HPFP’s today and fingers crossed that seems to have done the trick. I would have thought that they would throw up more more codes other then 118111 and 118011?

That’s interesting…any idea why EU6 injectors all have the same compensation value?

I'm not certain if this is causing your rich mixture issues, unless the injector was somehow injecting too much fuel. My F85 is at the shop right now getting a injector replaced, due to a Powertrain malfunction issue. And these injectors aren't cheap. Luckily, I only has one go bad.

Thanks for the info, I will check it. It sounds like you've already gone through quite a bit of troubleshooting to address the issue with your 2006 manual Z. Since you've tested the ECU in another car and it worked fine, and you're getting power to the OBD2 port but still no communication, it's possible that there's an issue with the wiring harness or connectors in your car. Given that the original owner swapped in a regular DE engine and harness, there could be compatibility issues or wiring discrepancies between the harness and the ECU. The suggestion you've found about repinning certain connectors, such as F1F2F3 and 102, may be worth exploring further. It's essential to ensure that all wiring connections are correct and secure, and that there are no damaged wires or connectors causing the communication problem. If you're unsure about the repinning process or need further assistance with diagnosing the issue, reaching out to a Nissan specialist or automotive electrical technician might be beneficial. They can provide expertise in troubleshooting wiring and ECU communication issues specific to your vehicle model. I also like to share my personal experience with you.

So I ordered a full set of injectors, @92,000 miles it’s time to change them, in the mean time I had ordered 2 HP fuel pumps and swapped them out, I am now going 2 weeks with out the engine rich across banks code. I will still change the injectors but i’ll wait until I have more time to do so. I suspect the internal seals of the pump were allowing engine oil past and into the combustion chamber with the fuel!
