Only 1 input is freed up. The other is an output. So you can certainly feed one of those sensors into the Procede. Just not both (at this time). There are some firmware changes that we an do that can free up another input and output. But that's not until later.

I'm the guy who keeps having really lean AFR's when on partial throttle, once the Procede is warmed up. You suggested I uninstall one of the 4 patches on the procede pnp harness that controls fueling (the subconnector patch with all the yellow wires) to see if we can narrow down the source of the problem. Unfortunately, I've been lazy and have not gotten around to doing it yet. So I'm wondering if the above might be a fix to my issues, if I've not got any codes. Or if I should still just remove the whole subconnector first and see how that goes and report back. |

Just did this harness update without any issues. The wires of interest were purple v's yellow for all the others on the sub-connector, making them easy to identify. I have an earlier rev 2 harness that also required the canbus wire update way back when. Looks like the colors have changed since then.

Question for the tuning experts out here: Is it pretty worthless to mount an EGT sensor in the downpipes (post-turbo) and add 200* from there, or do I REALLY need to take off the turbo/manifold and make a bung pre-turbo?

It is not consistent. Depending on load and duration, the delta in temperature will vary.

I am going to put 1 EGT and 1 AFR sensors in the same spot as the back lambda sensors and move them at the back of new middle mouted 100 Cell High flow cats.

Performed this harness update today, was particularly easy on my v4 as the wires being removed were purple so very easy to identify. I borrowed two red unused wires from the other harness.
Pretty simple, no codes or issues on my test drive. |

I'm still using a good old pre-29.2 firmware on my ECU and i dont want to change it (by any means). Shouldn't I do the harness update?
What could go wrong , given I have anyway the O2 setting at 100% , allowing the auto-canclear to do the job ???

just curious, does it matter if you tape the unused female and male ends so they touch each other or can you tape them individually?
