I just got off the phone with Doug from CrawfordZ, and he noted that with a CAI, True Dual exhaust, and High flow cats, I should be just fine. Our stock ECU has 8 base maps that will notice the mods, and adjust accordingly.

He did say that he has heard that the SSV makes the engine run richer, and might have to be leaned out, but he marked this as hearsay, and so, he wasn't sure about the SSV. + this was from FI guys' experience. I am N/A.

Buddy, thank s for your quick response. I had previously heard about resetting the ECU, and wasn't sure if this would be a more effective approach :dunno: . Both you, and Doug confirmed that this process is not necessary, thanks!

Actually there are about 3 timing maps for different octane modes and knock reduction.The ECU will not "learn" a mod and adjust for it under Wide Open Throttle conditions no matter what anyone says.All your doing by adding breathing mods is leaning out an already RICH A/F factory ratio.There is a point at which the increased A/F will become harmfull to even a N/A engine. The only time the ECU will trim or add fuel is at idle and under partial throttle loads,not under WOT. A lean A/F mixture would be ideal for adding some more fuel to make some extra power.
As far as the Kinetix manifold making the car run richer, there are two things that may be going on.
1) a vacume leak from a poorly machined surface causing rich A/F at part throttle
2) It is restrictive and actually flows "LESS" air/CFM than the stock plenum,which is more likely the scenario.

Tuning is key for getting the extra power out of the car.The UTEC is definitely a good option,I myself have just started tuning the UTEC on my own car in the past few days and feel like a pro already.It is really easy to use and tune even by the novice tuner....The Utec and the Tuner Pro provide to be a POWERFUL tuning tool in the right hands!

My zip is 75075, but if there is a database that you will be using, you can just provide me with its name - should be easier for you. I have already searched Google and Yellowpages.com, but I do not have any names of shops that I can trust. I know of Alamo Autosports, but that is a good hour away from me.

The tuners that I know of that are nearby me, are famous for ripping people off :headshake:

Alamo has a dyno; they'd be fine. All you are doing is paying them for their readings.. No tuning just yet. :wink:

I'll look for you later tonight and see what I can come up with. I have a few people in mind.. I just don't know if they are close to you.. freakin' Texas... sheesh.. it's like it's own country. :nana:

Here you go:

ATS Racing. I know the owner and people that work there. Def. okay. :thumbsup:

and it's only 19min. from your house. How is that for proximity? :wink:

Peace.

p.s. let me know if you are going to contact them and I'll be sure Aaron knows what's going on.

Man, you are da bomb! I will give them a call tomorrow. It seems like these guys are MR2 specialists. Have they done work on a 350Z before to your knowledge? Thank you very much for this info, I appreciate ya, and yeah, Texas really should become its own country as pretty much everything is different here.

Julian, thank you for the info, and believe me, UTEC would be my first choice if it wasn't for the cost. Not that I think it is expensive for its capabilities, but its my personal funding that would not allow such a transaction currently. Having said that, after all of the tuning costs and equipment combined, the price of the UTEC might not be too far off, so that could also be an option. When do you close the group buy???

:thumbsup: thanks man! Glad to help.

Yes, they have worked on Z's before.



Baseline Dyno Session - 3 pulls on dyno with wideband O2 $65 <--- is **** cheap too

So I was looking at some of the features / capabilties of the UTEC and found out that the only con is "Piggyback control over the A/F parameters ". What does this mean in layman's terms?

I believe it means that the UTEC controls the injectors Via the ECM, but it fires the coils directly.The UTEC has full capabilities of running the car from 0rpm-redline.I will verify with Jermain what "exactly" this means..

Chris, Just got off the phone with Aaron from ATS, and he sounded like a very knowledgeable individual in respect to 350Zs.

They are having a dyno day this Saturday, so they are offering 3 pulls for about $40. - Can't miss that. Plan on getting the exhaust installed, and will drive over to meet these guys and get an idea of how much power my car is putting down to the ground.

Just to verify, 350Zs run dynos in 3rd or 4th gear?


Thanks!

5th gear is 1-1 ratio,but most shops do 4th gear..

Good deal, glad I could help.

3 pull / $40 is awesome. Do it.

Most shops do 4th.. although 5th gearI believe is closer to 1:1 ratio.
