Yea but doesn't the ECU adjust according to averages over time? In other words it's current settings are based on historical data which should be cleared out so it knows that it's starting from scratch. I would think it can adjust faster with no prior settings holding it back...

 

I'm not sure. But a reset does bring the ECU back to its stock setting (ie--no mods). So I believe that you're then bringing the ECU back to a "less modded" setting if you already have a few mods installed (I have high flow cats).

 

Thats what I think about all the breathing mods. The car will learn on its own and adjust to the improved airflow. That could be good or bad depending on whether it negates the improvement or not. From reading other posts I don't think anyone really knows for sure if our ECU neutralizes the mods or not.

I don't think it does. It probably can't adjust enough to take full advantage which sounds more reasonable. That's why a properly done ECU flash like Technosquare can make a difference.

 

Moved.

 

Zin, how's the spacer treating you? Is life still good?

 

Sorry... not close enough in this case. If you were talking about an FI upgrade that's adding 100hp, you can use this rule, but not for an intake upgrade claimed to net around 10hp. There is no general rule on baseline dynos for Zs. They range from 225ish rwhp up to high 240s for completely stock Zs. Variances in cars and dynos ensure you can't say car X is going to run exactly like car X2 even if they are run on the same dyno.

The only way to be sure is to dyno the same car on the same day, with and without the mod.

ZinMiami...
The test is just as valid on your car as anyone elses as long as the only thing you change during the test is running with the spacer vs. running without. Your numbers may be a little higher due to other mods, but it will still generate a net power difference on a modded car running the part vs running without it.

 

Yeah, what he said. NOW WILL SOMEONE GO DYNO THIS THING!

 

No problems or issues so far. Still feels the same performance wise since my first report.

As for my average dyno comments and close enough etc. I understand what the proper/best way to dyno this stuff is, but to me this all just a hobby to entertain myself, so accuracy is not improtatnt. As soon as the headers and cats get done, I may dyno to get a baseline for use with the TS reflash. Then maybe another post re-flash just to see where I end up.

 

I agree ZinMiami... I wouldn't pay out of pocket for that dyno comparison. I thought someone earlier in the thread was offering to do it for free if you'd just bring your ride to the dyno.

 

Zin, glad to hear it.

Dr. Bonz, my brother has set up a dyno day coming this Sat. He'll be dynoing a stock baseline and then he'll run a 1/2" motodyne spacer and lastly he's gonna compare the spacers results with a loaned cv5.

Stay tuned fellas.

 

Yeah IMCOOL did but the spacer was already on and I don't want to take things apart. Something to consider for others doing this mod. Get it right the first time. The studs in the lower plenum strip very easily. I don't think they will stand up to too many on and offs.

 

It seems like there are suddenly 20 threads on these spacers...reviews, criticisms, buy now, get in the group buy before it's to late!!

Where did you get your Hydrazines spacer from? Do you have a link, because I am interested in the product. How much?

Right now there's a group buy that may be over for AAM's spacer?? Not sure if it's superior to Hydrazines? But it seems to level out the plenum. All the parts for a complete install are running around $176 shipped in a group buy.

Help...

 

Not true, He should reset it. He is running on the least agressive map right now. By resetting the ECU he will be running the most agressive map out of the three.

This is Tony Collette's email. He is Hydrazine and the maker of the spacer I have.

 

Yeah, keep in mind this should be in the proper sequence and 61 inch pounds (less than 6 foot pounds). When you try it on the wrench it feels like hardly anything.

By the way for those of you who may consider contacting Tony/Hydrazine to get his spacer, I can't say enough about what a standup guy he is.

During his GB on the spacer he offered discounted prices for 25+ levels. I ordered and received my spacer quickly but when the gb when over 50 he offered an additonal discount. Well today I got an unsolicited refund via paypal to reflect the fact that his gb reached the 50+ level.

I think it's great to find folks who do business like that and I can now not only recommend his product, but recommend him as an outstanding business man.

Tony, if your out there and read this, thanks for a great product and for the great ethics!

 

On the G35driver site, there was a person who received a 1/2" rather than the 3/8" that he originally ordered. He said that Tony sent him 3/8" with no questions asked and then told him to try both out. Just send back the one you like better.

I think that's very rare to find customer service like that these days. Especially in this egotistical industry.

 

Thanks ZinMiami...

I decided to go with the AAM's spacer. I just like the way it corrects the OEM plenum's drastic angle. It creates a more parallel symetry between the top and bottom piece.

Sounds like Tony is a great guy to do business with. Maybe in the future...
