Thanks for the graph! Do you have a graph with AFR from before and after?

 

I asked for that but they said they don't like to use the dyno AFR readings. Something about being inacurrate but I'm not sure.

 

Yeah, supposedly the O2 reading from the tailpipe (this is where it is read from with the dyno machine) can fluctuate a little since it can read some air that is not part of the exhaust output.

So i guess they must have read the O2 from the OBD2 port, is that right? Too bad it is hard to overlay it with the dyno, but I think he must have used Cipher to log so you can somewhat see a trace of how it was before and after. This will kinda show you how stable your AFR is.

 

We use an Innovate wide-band O2 sensor to monitor the AFR on all cars that we tune. We don't trust the DynoJet O2 that works directly with the dyno because it has shown to read almost 1 point off when directly compared to the Innovate. I'll ask Rob today what the AFR readings were on Bryce's car.

Don't forget that Freakmont is going on today at LeMans karting in Fremont. Our 370z will be there along with my turbo 510 so I hope to see a bunch of you.

Long Live the Z

 

Bryce,
How does the car feel? Are you happy with the end result? Was the ECU rest when you did all the breathing mods so that it could adjust to the new bolt ons prior to the tune? Why haven't you posted this in the HR section? I think you would benefit from the information that will be given to you from people already using the system.


Forbes@ZCG,
After reading your first post, I realized that the shop didn't know exactly how to tune the HR with the up-rev. Will Rob/Tuner be re-tunning Bryce's Z? I honestly think that the tune isn't to its full potential, is Rob/Tuner just playing it safe?

 

The car feels fine. It runs smooth and there's power but I'd have to agree there's probably more to be had. I don't know if the ECU was reset or not, I know that I didn't reset it at all.

Am I happy with the end result, not totally. I expected to break into the 300's with all the mods I've done and I'm not even close.

I don't feel the need to post this in the HR section. I don't really have any problems or questions that I need answered, the purpose of this thread was to make all of you aware that ZCG is now offering tuning services and that it did make power on my car.

I'm sure my car could be a little more fine-tuned but I'm looking ahead towards some suspension mods. Maybe after we finish the suspension we could come back and see if there's more to be had regarding performance. With my final numbers the way they are, it doesn't exactly inspire me to try more mods as I think I may have a weak motor.

Maybe I'll have to start attending some meets here in the Bay Area and get some feedback about my ride.

 

I hope you reconsider, it will help others and there might be some good info that might come out of it.

Weak motor? What kind of tests were performed to come up with that conclusion? Is that what ZCG is telling you? Bryce, Im in no way poking fun @ you, I was excited when I first read your post. At the moment however, Im not getting in line to get this done @ ZCG.

 

Maybe it's because they don't have that much experience tuning the HR motor since it was their first try, or maybe they were just playing it safe. I was expecting 300+ as well, like 310-320, but maybe I dream big. Hopefully Forbes replies to this thread and updates us.

 

Maybe I should post the dyno with my car and Bill's car in the HR section. His car make a sh*tload more power than mine and he has fewer mods.

 

There is no doubt in my mind that they don't know how to fully tune the HR. My problem here is that it sounds like Bryce is being left out in the cold in regards to his tune. I too am hopeful that Forbes (or better yet, Rob himself) updates us.

 

Just for you Cali-Darkness, here's a thread I made in the HR section.

https://my350z.com/forum/vq35hr/4379...tle-power.html

 

I wouldn't say I'm being left out in the cold, Rob and I never really talked about it. Don't jump the gun just yet. The next time I'm over there I'll probably bring it up and see if I can get some answers. Like I said, I'm trying to get my suspension done before I revisit the performance part of my car. My car is a work in progress, Rob and I are well aware of that.

 

Cool, hope it works out. I want to get mine tuned but I want to wait and see what the shop does and learns in tunning the HR. Im sure the numbers will eventually get better.

 

Actually I was told my motor was average but from the dyno's I've seen of other HR's that had mods done at ZCG, my motor is a dud or something's not right.

 

Fact: Bill's car makes amazing numbers without a tune

Fact: Bryce's car picked up 8whp after the tune on an NA car with bolt-ons, .

This is our fist venture into this software and Bryce simply offered to spread the word about us becoming dealer

Those are nice numbers unless you have unrealistic goals, and the car can be re-tuned if we discover that we can get more out of it or when Bryce adds more parts, which he is bound to do.

Most people who think ill of us have never been to the shop or talked to us at an event. I suggest all of you to do both, and if you are still not impressed simply don't do business with us. No bad feelings.

There is no need to badger Bryce on his power numbers or to continue just post to hint that ZCG is hiding something or doesn’t have the skill set to help him with is car. As we gain more experience with the software we will give everyone who is interested our help.

Lets stay constructive and keep these forums what they designed to do : HELP US ALL MAKE OUR ZS BETTER!

We love the Z and will continue to serve it and our customers in the best way we see fit.

Long live the Z.

 

Well, I'm moving on to suspension. I'm done thinking about dynos. My car runs fine and it's in need of a drop so that's what it's going to get. For anyone who's wondering, here's the components I'll be using in my suspension.

Bilstein PSS10
Hotchkis Sways
Powergrid Endlinks
SPL Front Camber Arms v2
SPL Rear Camber Arms v2 w/ Toe Bolts

 

This will be my last post in this tread....

Badger, really?

I was honestly offering an opinion and was trying to do it with the up most respect toward Bryce. Unfortunately Bryce just informed us that he had not yet talked to Rob to let him know he was unhappy/concerned about his tune. Had this come out sooner I would have never posted and I would have waited to see what Rob was going to do.

Forbes, I don't think ill of ZCG and Im sure members here that attend the East/South Bay GTGs have heard me say that I enjoy hearing Rob talk because the information he offers has always made sense. I have NEVER had work done @ ZCG because I haven't had a need as of yet, but not because I don't like them. I was honestly excited when I first read this thread since up-rev is a solid mod. I was a little disappointed in the numbers but like I said in this thread, Im sure with time and practice those numbers will improve. Maybe its just me, but its your own posts that contradict themselves.

Im done with this as it isn't my problem and I told Bryce where I was coming from via PM and we are good. I also have much respect for Rob, I will leave it at that.



Looks like you are planning to go low

Endlinks a major plus, especially if you go with a stiff setting on your sways.

Good Luck Bryce and best wishes
