Need help with these injectors??

[rixcidia]

Hey guys so I was cleaning my garage out and found these 510cc injectors that I have never used but came with the JDM version 4g63t engine I bought to replace my blown one I guess the mechanic put my injectors from the blown engine in so I'm guessing they are stock 440cc injectors are these yellow 510cc injectors usable and recommend for replacing the other stock ones I'm using, I got the evo I 16g turbo and I am thinking of running dsmlink in the very near future.

Awesome thanks for the tips I forgot to mention when i install the wideband do I replace my stock front o2 sensor with the sensor that comes with my innovate MTX-L Wideband Gauge Kit?

That's one of your options, within ECMLink you can enable "narrow band simulation" and just replace your stock sensor altogether. Otherwise you can use the weld-in bung, IIRC 36" downstream from the turbo is what's recommended. Then you have to choose an unused/unneeded pin for the 5v input to link.

What do you mean by choose an unused/unneeded pin for the 5v input to link? Do i have to do this still if I replace my stock o2 sensor? What the disadvantage of replacing my stock sensor with the wideband o2 one?

With DSMLink you can log your wideband. However, it has to be tapped into the ECU so that Link can read it. You simply cut and splice your wideband's output into something like the stock Front or Rear O2 input. Then tell DSMLink to read the Front O2 or Rear O2 input as a wideband.

If you replace the stock Front O2 with your wideband you will need to simulate the stock Front O2. It controls fuel trims at idle and cruise. The only disadvantage to this is that the narrowband simulation can give you a wonky idle if not setup right. There is also the thought that being that close to the turbo can cause damage to the Wideband sensor. Other than that people have had no problems doing it this way.

Your other option is to weld the supplied bung into the downpipe. Then use the rear O2 sensor pin for the wideband input like I described above. I would suggest this as it lets you keep the Front O2 as well as gives you an accurate reading for your wideband.

Ok perfect thanks so much for the helpful advice reason for my question is because my front o2 wires are looking like they are starting to fall apart close to the sensor it self and with repairing my turbo and buying this whole setup I don't have much more to spend on a front o2 sensor right now.

Yes it's a pretty popular spot most don't have a problem with it even though they don't make the heatsink to go with that Innovate recommends in their installation guide but look around for any specifics as this is a pretty common setup
