Got my car tuned with UpRev

Kastley85891 · 05-01-2010, 09:05 PM

I deleted my uprev editer a couple of days ago, I assumed that UPREV had access to the same tables as COBB, maybe they do only have one area for rpm limit setting, that could be the issue if there is still a limit inside your ecu unchanged?
I will down load the UPREV editor again and take a closer look - cannot download form PROC - take a look at your own hex file (or what ever format UPREV use) and see what tables are open or if locked by tuner look at a stock rom image.

when we tuned my car the other day, we could only tune up 6400 rpm. that is all the program would show for fuel tables. Has everyone else experienced the same thing. Uprev said we have to ratio out the table? Not sure why we would have to ratio out when my buddy 350Z showed his entire RPM band. Anyone else experience this?

You know what? I'm just going to say it. Uprev's support for the 370Z right now is half-baked at best. I'm really not very impressed.

I am half tempted to get a dyno tune with cobb, but I know Uprev did a very good job for the 350z crowd, from those I have talked to in Houston.

Yeah I know. For the 350, Uprev is IT. And that's why I went with them for the 370. But I have to say I'm disappointed with what they've put out thus far. They have not measured up to my expectations, which I based on their reputation in 350Z circles.

Maybe I will keep my LTH off for awhile then until this whole tune thing gets resolved.

Problem is you might be waiting an awful long time. Just go ahead and put them on now and use the tune to adjust AFR. You'll get some gain out of a tune, just don't set your hopes too high is all. The G guys seem to be getting better results though. Same engine, but the ECU ROM files are different.

As in this half baked?

Probably true, would love to finally hear the exhaust fully opened since I am on still stock cats.
Just sucks that right now I have to drop so much for a simple AFR fix.

The other bet is, will Uprev come out better or will Cobb? Both can do simple AFR fixes, but down the road will be the true winner.

right now I think Cobb and Uprev are doing this about the tune.

Im in a visual mood.

Can some one open there UPREV rom and post up an image of tunable parameters

Here is list of current COBB avaliable tunable areas.
Notice COBB only goes to 7200 in fuel area, above this the ECU will still hit target based of the current table data, at 7500 it should match the 7200 targets relevant to load injector setting etc. Hope that makes sense.
NB - I am not trying to push COBB over UPREV. What we really need is a third party option with cable purchase (simular to the Subaru and EVO, Honda platforms) and downloadable software, I suspect in the future more options will become avaliable.
Anothe roption for fuel fixes , all be it a bit crude , would be some one to develop MAF tubes slightly over sized but properly/accuratly calibrated that could be incorparated in some way, personally I would wait for a MAF tuned AFR fix.

So to answer my own question, people are having the same issues as me?
