Foxwell NT510 Code Injector Issues and Solutions

Here 3 pieces of Foxwell NT510 code injector Issues and Solutions, hope it helps those who have the same issues and looking for the solution.


Q: Foxwell NT510 can code injectors?

A: Yes, just did mine yesterday with it, very easy and intuitive to use as it guides you through the process. It has access to the TCU and TCU parameters yes.


Q: Had a problem coding injectors with NT510 scanner, I’m inputting the two 3 digit codes and either the DME or the tool won’t save the changes.

A: You have to re-enter all 6 digits together no spaces. You cant just do 3 digits. Also the DME separates the 6 digits code for the injector into two 3 digit pairs automatically.

Finally, I think I got it to work. NT510 scanner states the codes are “not ok” and intermittently displays the “correct” numbers after going back to the beginning of the process of coding them multiple times. Might be a little buggy… Interestingly, there is a note in the prompts that says the last digit may be altered/adjusted by the DME. Sure enough. The car seems to run a lot better with the index 12 (7 & 8 came out).


Then I got correct guide: the DME defaults to a low range of the injectors specs by -/+ 1 of the last digit of the set. That is normal. If you want the full range of the injector spec ie closest to the actual numbers displayed on the injector, then you need to offset entry.
Example, if you enter 477 and the DME changes it to 476, then enter 478 to target 477. If the DME adjusts to 479 then you will have to go back and enter 477 and 476 will be the highest you can go staying within the injector specs and not exceeding it.


Q: When I tried to save the values, the tool said they were not valid. Any idea what I did wrong?

A: update the software for the tool, then select your device first by VIN, it will load a pre profile. Then go back and select your chassis and model manually. Go to service and try entering the values again. You can also try saving each cylinder entry one at a time. Finally solved.
