Getting UpRev done, what should I specifically ask the tune to include?

cg2006 · 08-15-2013, 10:30 AM

Anything else you suggest they do or I should ask for?

Remove the ecu inputs for the 2 rear oxygen sensors. They will still cycle, but if they ever operate outside their voltage range, they won't throw a code.

Will this be a problem for obd2 tests, that the sensors aren't detected, so they will not read for the test = fail?

Make sure they remove the Top Speed governor, that way you can do a full dyno pull in 5th gear if you choose to do so.

Nope. They still cycle open/closed loop. But their inputs are blocked from the ecu. Thus, no code will be seen.

With my LTH's, I haven't thrown any codes...

But I should still have the tuner do this, just as an assurance.

I was throwing codes all the time before my tune. With the exhaust mods, this is not uncommon. My tuner removed the inputs for the rear sensors (UpRev). While they still work and will send the voltage signal that adjusts the afr when the engine is cold, their voltage signal is blocked from the ecu. So, they always "look" ok even when they operate outside their voltage range. Best of both worlds.

Interesting. I will have to let my tuner know this (If they don't do it already) when I get my tune looked at by a 2nd opinion.

Right now, I'm not satisfied with it.

I would suggest asking the tuner to be sure he includes more horsepower with the tune. Sometimes that part gets left off.

And if he says, "When do you want me to have VTEC kick in?"

You ask for your keys and run.

no no no you say "Right when I need it, yo!".

I drive an Si, and I can't seem to find my Vtec.

Found it...

Im pretty sure the secondary 02s will make no change for you. Those don't control AFR... That's why the primaries are specified as AFR sensors and the secondary's are 02 sensors. The 02's are purely for emissions as far as I know. I also run no secondary's now and have no issue.

I'm also getting tuned this Saturday in NH. So far I've gotten this from some searching:
