UpRev ECU tune results for Semtex's Z

RCZ · 11-03-2009, 09:26 PM

Umm...sounds like you guys found the issue. Now to fix it...

PunKidd · 11-04-2009, 01:27 PM

Yep, sounds like something in the ETC patch is haywire.

cotizi is going to drop his Z with us tonight or tomorrow so that we can start the trouble shooting and get this resolved.

Glad to help.

I dropped my car off this afternoon, so hopefully they will have the fix worked out by tomorrow, but we will see. Based on what Jared told me, I think the more time they have to work with an actual vehicle the better for all of us.

Thanks a ton for doing this, cotizi! Giving you some rep.

good job cotizi!

Well, it doesn't appear to be a problem with the ETC. It looks like it a problem with the ignition advance. Stock car when cold runs between 30-45 degrees of advance as you tip into the throttle below 2K RPM. With the Osiris ROM it's running -7 degrees right up to the point where the engine actually starts to rev up.
We've got a few things to try, but we can only run 1 or 2 test before the car is up to temp and the problem goes away.
I'll post more tomorrow when the car has cooled off and we can run a few more tests.

The throttle DTCs are probably due to the ECU seeing the sensors rise, but the engine RPMs stay level or even drop.

There is such a huge clash of discussions going on in this thread, its sickening. haha

cotizi · 11-05-2009, 05:16 PM

Just got off the phone with Jared, I'll let him explain exactly what they did, but looks like they made necessary fixes, and have moved on to dyno-tuning my car tonight.

I agreed to let them keep my car until tomorrow afternoon so they can get some more time with the car to add in some development features they are working on.

get excited! lol

Hey where did you get those slick straight pipes LOL

Had my Titan over there on Wed and saw your ride looks like you got some the nice Austin hail!
You will see a big difference with the tune.
The Titan kicks *** now almost as fast as my 370

Dude my poor car. I ate hail 2 days before I moved into my new house with a garage.

Got bored one weekend and decided to make those turn-downs to see what it would sound like. They are quite ghetto but hopefully my FI exhaust will ship Friday or Monday!

I was watching Jared tune your Titan on the dyno. Pretty impressive!

Cotizi, did you not already have your car dyno-tuned prior to this? Does this mean that once the fix is in, we'll all have to have our cars re-tuned???

theDreamer · 11-05-2009, 05:19 PM

Oooo, new development features, do you have more info on that?

cotizi · 11-05-2009, 05:23 PM

Not really to be honest, I think its mostly adding back in some features in Cipher that are currently unavailable for our platform.

B1nks · 11-05-2009, 08:05 PM

didn't expect to still see the blue 350z in the parking lot in that pic. That poor guy, oh well thanks for spending all this attention on us UpRev !
