Roll your own tuning?

Abilor · 08-21-2011, 01:29 PM

Gentlemen:

I am relatively new here in terms of posting. I face a dilemma: for the first time, my Mazdaspeed 3 is no longer upside down, and after three years of working and tuning it, I am getting ready to let go of it, get a Mazda 5 for my wife and baby, and set about getting a new car for Daddy...

Right now it's down to either a 370z with sport trim at a minimum, or a 2011/12 Mustang GT. I will buy used, and reinvest the difference into mods. I am leaning towards the 370z and want to go whole hog: Intake, HFC/CBE, stiffer mounts, lowering springs, etc. And of course: F/I.

My concern right now though is that I have gotten very used to using a datalogger and Cobb AccessPort with my speed3, and the idea of not using my own tuning software to do a street tune is foreign to me. I read that a lot of you are going to Stillen, GTM, etc., but does a handheld programmer with tuning software similar to the Cobb solution exist for these cars? I know dyno is the way to go for precise advancing of timing, etc., but a good street tune that optimizes AFR, BATs and IATs, EGTs, and most importantly for F/I, knock, is something I'd want to tinker with constantly as I mod, mod, and mod some more.

How are y'all doing this?

Potential 370z enthusiast.

hehe...

Why don't noob's read?

Found this elsewhere, and I guess it's what I'm looking for: Osiris - Tuner - Osiris

Anyone having luck with this with the synchrorev and VVEL features? It's the biggest thing that scares me about tuning this platform.

neither of these matter for tuning, SRM and VVEL are black boxes that you wont be touching with Osiris. From what I have been told the maps inside the 370z ecu are a bit crazy, much more complicated than whats going on inside the 350 ecu for example.

Some maps still haven't been cracked by uprev yet. For example we have no control over the tip-in/throttle enrichment maps. This means when running larger injectors you wind up dumping a bunch of extra fuel when initially stepping on the throttle as there is no way to compensate yet.
