where should we be aiming for AFR wise? I would have thought tune would have been super clean, they are a pro uprev dealer. I see my peak number flatten out and the AFR come from around 11.7-11.8 to 13. there is a lot of unburnt fuel I think it could go a little leaner.. I know safe is good but kind of looks to be quite rich.

also what sort of timing should we roughly be looking at? I can ask what it's at or any graphs of it, forgot to ask about it. Any help would be appreciative and I can point them in the right direction and we can do some testing to make sure there's no detonation.

It's currently middle of winter here, so out and about most places where I am, gets down to 0ish-10degrees celcius while nighttime, would you also advise a sort of summer tune? pull back some of the timing during the hotter weather?

Also from the speed on dyno sheets, looks to be 3rd gear pulls, wouldn't 4th be better in a 6 speed?

Next up is potential E85..

would I see full benefit from it considering the kit as it is, is pretty maxed out considering the charge pipe/maf's etc..?

I haven't seen anyone else with the stillen kit on E85

My car has always ha 4th gear pulls.

You would probably be the first known on the forum to do e85 for the Stillen kit.
Waiting on final results of a GTM SC kit to see any potential in general for the 370z with SC. I would say you might see more power increase as you can push the car a bit more while keeping it in a safe range. Though you just did your install and I would say to make the jump to e85 would require some new fuel parts you just installed.

yeah, is there someone doing E85 on the GTM SC? got the link to the build?

won't be doing it right away, probably after april next year (going away overseas holiday for couple weeks). I was going to do it straight up with the stillen install, but the difference between the tuner kit (minus fuel pump/injectors) and the full kit was couple hundred, couldn't justify it. Just figured I'd install this for now, tune it get used to the added power then step up later down the track, would possibly still be able to sell the fuel pump/injectors cheap to someone local here in Aus by then.

also not to mention how much of a pain it would be to get to the injectors again haha, stillen manifold is a bitch to put on.

Here is his full build thread, but it is the last couple pages we talk e85 with the GTM kit: http://www.the370z.com/members-370z-...k-out-lot.html
He is currently working on a couple issues to finish it up, but looking positive. The only negative I see to e85 for us, is we are static with our boost. So we run xPSI and throwing on e85 might give better cooling and allow a little more timing but to see full benefits we might have to bump up the PSI or generate better flow in/out of the engine to great that perfect efficiency setup.

thanks mate! will keep an eye on it and see how it goes.

yeah I was thinking the same along the lines of the static boost thing.. guess we will wait for his results, we might have a lot of E85'ers coming up haha

Yep, the TT guys are eating it up right now but the SC owners are staying away. I want to make the jump (tons of e85 stations here), but not sure if it is worth the investment. I don't really need more power, need at 400 since 2010 and love the level, but the added protection is very nice.

yeah I'm hearing you there, extra protection would be awesome.

have you done any tests on your local stations to see how the levels vary? that's the only real concern I have about swapping over, is getting a low batch of fuel, guess would need to at least have a test kit every tank of fuel.. kind of annoying for a daily drive, if the other guys results are good though, it'll be worth it to me even to check every tank.

I've got 3 stations within 5-10 mins of me, might run some tests over the coming months and see how the levels vary.

Not yet, I know the top stations people use here and I am near or travel daily past them.
Probably before I made the jump I would test a few to compare differences mostly, and my other goal is to have a second car by the time I make the jump so I am not that worried about DD it anymore.

yup yup, mines not so much a DD but it is my only car, I work from home and only head on-site for hardware replacements/meetings etc (IT consultant).

so it won't be so bad, I can generally go a couple weeks at the moment with a tank of fuel if I don't go out to any car meets on the weekend.

well fingers crossed for decent results! we know there will be 2 more at least if there is decent results ;) haha

You'd have to look at timing tables to see all that. Nissan is really confusing as the timing tables aren't in degree but some kind of unit based off cylinder pressure.

It doesn't look like it is running super rich, but it could be smoothed out a little and optomized. Right around 12-12.5:1 AFR is going to be your target range (closer to 12:1 to be safe).

As far as a summer tune...the tune should be able to compensate for the temperature differences but I would have it checked when it gets warmer to make sure everything is good to go.

sorry about that I took it personally.

so whats everyone running in terms of redline now with the kit, are you guys keeping standard redline or increasing further?
