I'll second what Dreamer said. I had a hot start issue after installing my TT and Sam fixed it with a tweak to the tune. Starts like stock now.

Sweet...but here are my numbers...the ones I know

2009 AT7 370z
STS Turbo System- First STS AT7 build
445hp @ 8psi trq - unknown:shakes head:
Stillen Oil Cooler
Methanol Injection
Elevation is @ 1000'
2000 miles since install
more coming--Remote mount oil filter, body kit,etc.

If the next shop does not resolve the hot start issue, give Sam a call with the tuner and he can help you out so you can be running 100%.

Alright....sorry I haven't read the whole thread. Who is Sam?

At GTM.

He doesn't have a gtm kit, doubt Sam will be able to help.

I know he doesn't, i was just telling him who sam was. :tiphat:

Sam is very helpful, just because you have X kit does not mean he will hang up on you, he is here to help the community.

Alright, thanks. I'm gonna try to get into another shop tomorrow and see what they can do for me. If all else fails I can have them call him. I hoping that there shops dyno doesn't look like it was built the same as the model T was built.

Hey Tower37,

Is your car idling right after it is warm - is it managing a consistant 650 rpm idle?

If not you might have an air leak on your injectors or inlet manifold, or even MAF sensors.

if that is all good, you might want to check your cranking enrichment. What software are you using for tuning?

I'm sure it was something from the seveties. I know that I got a off and on problem with my ignition coil but that's an easy fix. The tuning cable was on a serial port. Knowing a little about the serial port cable, they haven't been used in almost 10yrs.

I would recommend that you approach Sam at GTM for Osiris software and a tuning map for your car. You can't underestimate the value of a good tune from a reliability point of view.

Sam will be able to set up the cranking enrichment for you with the editor software.

Our cars are very sensitive to cranking enrichment - especially when using larger injectors. I had the same problem and Sam helped to sort it out remotely - I am based in South Africa. Car starts perfectly every time now.

I will have to try to call them after the holidays and see if they have an idea on a good tune for my car. They guys from STS had to basically use my car a test run for the AT7 tranny. So I really don't know if we are anywhere close to what it should be at for this type of Z.
Luckly the rattle was a broken clip on the piping under the car and was an easy fix for the guys who installed the system (for free).
I tried to get it tuned yesterday but with it being last minute and so close to the holidays they didn't have the time. So no biggy it's winter and the snow is only around the corner. With my body kit on its way ,time is on my side.

With FI, the tune is the most important aspect of the build. You can make little power or a shitload, run like a champ for years or blow up the same day. It's all about the tune! CIN Motorsports in Charlotte, NC (a longass drive I know) is awesome, Bobby and Ben are a/f doctors and as good as anyone out there.

Yeah that would be a haul. The tuner scene here in KC is pretty much dead. Most are ricers with the fart cannons and WTF body kits. I'm hoping that the one Tuner shop in town will be able to tell me if the setup is correct and maybe STS has figured out a proper tune for the AT7. Hell that's why I'm on here, gotta go where the people know the most.

Ok another question....unless the world has ended and no one is on here anymore. I seem to be getting an up-rev when the engine is cold. Tranny problems???? It only happens when I'm shifting from 3rd to 4th (on the AT7 tranny).

It being 2012 tomorrow, I suggest you peep carefully out the window every morning , to see if all is still intact :-)

An uprev when cold is normal, this is the automatic "choke" function. Sounds like you have a cranking enrichment problem. Contact Sam, he can sort it out for you. From my experience sounds like your cranking enrichment is too rich. Once you lean it out the car should fire up just fine when hot. This all ussuming that you have larger injectors, of course..

I will have to look to see what size injectors STS sent with the kit but yeah I will have to call him.

Here's an update pushing a little over 9 PSI (447whp and 380 ft-lb):
http://www.the370z.com/members/digit...t-lb-9-psi.jpg

I have dialed it a tiny bit since then, so it's pushing close to 10 PSI now.

Great numbers, now just wait a little while and you will want more. :p

Too late, I want more. It's still too easy at 450whp, but that's because my tires are 2 weeks old.

Update after full UpRev tune:

419WHP/350WTQ@8PSI

Nice bump in power, good to see I still have a little room to grow if I want to push my tuning a little more.

Nice.. I cant wait till I can post up my results in this thread! :excited:

get in line :stirthepot:

Already am.. I just need a fast pass. Hahah should only be a few more weeks here...

^ whoa, what happened to the TQ? how come it's so low?

dunno... not worried about it, whp curve looks about right to me... proof will be on the track soon I hope! :)

How is the supercharger
 

I was wondering if you have any regrets with your supercharger. Is it to load?

Great to hear Travis, updated the list with your info.

Nope, still loving it. The noise does not bother me other than I always want to hear the supercharger, but I get plenty of chances. Honestly, when I had my LTH+exhaust I heard my exhaust a bit more than the SC but since the LTH have been removed it is 50/50 on what I hear.

How much power did you gain back from removing your LTH's post SC install?

I am sure its in your thread somewhere but I havent seen it :)
