Over the past couple weeks, I have done over 50 dyno pulls with my z getting it tuned.
Due to the temp (100 degrees with 100 humidity) I didn't want to push the car to the limits, so I don't have peak #s to boast

What I am doing it building a very good map, the will be good for 7-9+ lb boost levels.

The map is based on pressure (not MAF like stock GReddy map) and is ten times better then the stock GReddy map.

Those with 255 fuel pump will be able to run up to 8lbs of boost, and for those that want to go higher, will need to upgrade their fuel system.

8 lbs has me at 400 mark, with the same torque.

Have done 9.3 lbs boost runs on the street with A/F at 11.4 at the leanest
Testing on a few different z's with just fuel pump, ungraded fuel system, and will soon test on one with just GReddy TT kit, no fuel upgrade.

Hope to have these Maps complete in the next couple weeks.
PM if interested

 

You certianly have been busy this summer...you know I'm interested.


Concerned about whether the maps tuned for a 6MT will apply to my 5AT. Anyone know if the TS reflash for the two tranmissions are same/different?

Thanks Tim, for all the effort and informative posts.

 

i'll be interested in seeing the maps. TIA

 

I'm interested too.

 

PMed. I just purchased my pressure sensor harness and planned on making the switch next weekend.

 

I am very interested in the pressure based maps. Nobody, until now, as had the time or dyno dollars and stuff to tune with pressure. Nice work!

 

Unfortunately because of how much time and money went into this, it won't be for free.....

Also think we will all agree, a safely tuned GReddy TT kit, that will add 50-100 Horsepower is pretty valuable...

 

Certianly agree ... ^^^

Back to the 6MT vs. 5AT maps...anyone know if ACP's maps tuned with the 6MT will match up o-k with the 5AT??? Or who I could contact for more info?

 

Understandable.
Will the maps include timing too?

 

What gear are you using on the dyno to tune? I have noticed my Z runs really rich in 4th - 6th, but I have it tuned perfectly for 1st - 3rd. I'm sure it has to do with the calculated load the ECU is seeing in higher gears.

 

I am also curious to see your maps. I am using the same approach as you so I think my maps will be comparable to yours even though I am running it on my Maxima. It will be interesting to see what our differences are (if any).

I am tuning mine right now with the e-manage maps, DFMU, and wideband O2. I have also held 10+ psi of boost with this setup. The only reason I have gone so high is that I have the DFMU increasing fuel pressure as well as the e-manage increasing the injector pulse width and retarding the timing.

Here is my question:

After you hit 100% dutycycle on the injectors (usually 5-6 psi for me), how can you get any more fuel with the e-manage injector map without raising fuel pressure? The e-manage is only adding pulse width to stock, but 100% is 100%, sooner or later we hit our max dutycycle.

Do you have bigger injectors?

 

Are you tuning the maps using the MAF Hotwire setting?

 

Tuned it on the Dyno in 4th, road tuned 1st- 3rd.......

 

I just decided that I want to run more boost for now even before the new motor and FCON tuning... so I think ill go ahead and install the pressure sensor and build some maps for the car as well. Once we are both done would be interesting to compare.

I am going to see how far I can go without even touching the fuel system at all. I got every part possible to upgrade it... but i was gonna hold off. I dunno, havent even begun to try it yet so I guess we will see how far I make it. I dont want to go past 7.5 psi i dont think regardless just cause I have a guy lined up to buy this motor out of the car when it comes out in a few weeks to be replaced with the built one.

 

There is no other way besides increasing fuel pressure. ACP has a pretty trick custom fuel rail and rising rate FPR and return line. So he injectors are getting more consistent fuel than those without this setup. You are correct, in that the 440cc injectors are maxing out pretty quickly, and once they reach 100%...they are done. But since ACP is increasing pressure as boost rises, he's flowwing more fuel..even though his injectors are at max duty cycle.



It cant go very far at all. I think you already know this based on your other thread. When I did my road testing, the stock fuel pump pooped out at 6.5psi.....beyond that...I was running in the high 12's on A/F towards redline...too risky for me. And the injectors hit 100% duty cycle at a mere 5000rpm.

 

Brian,

I am sorry I missed your question
YES, it includes timing as well.

KShep purchased my maps, I am sure you will hear his reviews when he gets his back, and loads the maps, and does some test drives..

Its like a Techno reflash, but at less the 1/2 the price, AND you have control to edit

I have it now, so the Map is good from 5-11+ lbs of boost
And the whole chart is broken down in very small sections, so it pin points the exact cells our 350Z needs.

You will hear more about it soon I'm sure, as people post their review.
I will even add, if you are not extremly impressed with the map, and how it runs in your z, I will give you a full refund.

2 things to add
I will only sell to those who are logging wideband o2
and you have to send me your e-01 card for me to load the map

 

Hi Tim, can you PM me pricing so I have it. TIA

 

Thanks Tim. I greatly appreciate your reply.
Can you tell me what your maps will require for me to run at 8psi as a daily driver? I already have the timing harness and plan to get the fuel pump. Anything else I should get for now?

 

I wonder how close this map would be for the G35 6spd.

 

Should be very close to the 350Z. I am running a 350Z ecu in my g35 6 spd with no problems.
