Also keep in mind, that with that little standalone unit, it has maps for valet mode and anti theft as well as your custom maps, i'd hate to have to bring my laptop with me everywhere I go just so I can access a map.

Now what I need since I dont have the Nav is a touch screen that I can hook my cobb to and see and do all my stuff right there.

I will dyno tune, hoping to go to Austin to meet (again) the Uprev team but a shop in Houston now offers dyno tuning with Uprev so not sure yet.
I have never gotten into tuning and will be glad to have someone do it for me at first, but like many things I do I will learn myself on what to do and such.

think you could do a dyno with just the map, then another after they dyno tune?

You mean with the base reflash prior to adjustments? I think they'll automatically do that. Actually, they have to in order to establish a baseline for the tune.

Yea a dyno after they load the new map and then one after they tweak it on the dyno. To get an idea how much the dyno tune will get you over a canned map.

I can't speak for Cobb, but I can tell you that when you reflash the new ROM into your ECU with UpRev, that base map is exactly that. It's a base map that has all of the factory parameters, and assumes no mods. By itself, it is not intended to yield any gains. Its sole purpose is to provide the tuner with a platform on which he can load maps that he builds via the process of running your car on the dyno. You see, the factory ROM that comes from Nissan allows no such thing. There are no 'slots' to drop the maps you build into, so to speak. So you replace the factory ROM with UpRev's ROM, and their ROM has these 'slots' for you to plug your performance map(s) into (as well as your valet and anti-theft maps).

wow this thread is awesome, so much good information!

Red370 · 03-25-2010, 03:50 PM

yeah i'd like to see that myself

theDreamer · 03-25-2010, 03:51 PM

Semtex is right, they have to do two (or more usually) runs.
The first run will be getting my current baseline numbers, AF ratio, etc. Then they will start to do more runs smoothing everything out and making adjustments as needed.

Oh OK I guess I was under the impression they would load a canned map first then do the dyno tune.

Zsteve · 03-25-2010, 04:02 PM

so to find if Im running lean right now, what gear and rpm range should I do a AFR check in? I have the 7AT.

semtex · 03-25-2010, 04:03 PM

Doesn't Cobb log the data as you run through all the gears? Like it doesn't require you to stay in just one gear while you log, does it?

Im not sure I will see when I get it, I know it logs just dont know if its an all time thing or not.

I think Cobb has a tuners software program you can buy to do that.
