can the speedoe be adjusted with osiris, if i choose a high or low FD gear ratio?

 

Nope

 

suggested redline for a built motor twin turbo application? 91 compression ratio.
max boost pressure 27psi. apparently 9: 0 :1 does a dancing smiley :-)

 

I think the fancy smile was the universes way of loving your 27lbs of boost VQ. I can only imagine.

 

You should discuss this with your engine builder

 

Yeah... What's your highest press boosted e tune?

 

Zero... No one tunes FI G35's with etunes

 

I'm troubleshooting code P1273 and about to swap bank 1, O2 sensor 1 I've been tuned using uprev software my question is this: is the lean shift causing a change in the tune (a/f ratio) to where it's causing possible damage to the engine? And once I change out the 02 sensor do I need to clear/reset the ecu self learning ?

 

1273 and 1283 codes are not necessarily because its running lean, as you suspect its usually from either an exhaust leak or bad O2 sensor. Very unlikely it will cause damage to the engine, but it does affect the long term fuel trims and that will throw off the tune. Once the underlying issue is fixed all you have to do to reset this is clear the learned fuel settings in cipher, or reflash the tune again with Osiris. That clears out all the stored memory and you'll be starting fresh.

 

This thread should be sticked to the top. Very helpful. Thanks Seymore4 for your insight.

 

One more question. Can I replace the o2 sensor and drive it to the tuner shop safely? Or do I have to clear the ecu self learn right after install

 

Totally fine to drive.

 

Alright. Thanks again.

 

Quick question and I figured to get the most eyeballs here.

I have an 03 with your base tune and just picked up an Innovate 3844 wb kit. Any suggestions on where to pull power..etc from so I don't have to spend time looking for wires when I hook up the gauge.. just tap and go.

ready to log this a/f as soon as I get it installed

 

I'm passing my G on to the girlfriend and feel like Osiris isn't really necessary any more as she has absolutely no interest in it. I have the Cipher cable licensed to me as well and wondered what the procedure would be to sell it. I've read through all the UpRev information online and this is either not listed or I missed it. Also what would be a fair price to ask, you can PM me with answers if you prefer.
