Went to the dyno today. I continue to learn about my power FC and the datalogit hardware/FC Edit Software. I will post a pic below. Basically all I did was show up and tun. first run is untuned right after I arrived the last/best run was after about 45-50 minutes of tuning. no new parts just a little tinkering with the fuel settings.

This dyno is low compared to most so I am pleased with the overall result. (Ausmith has even comapred this dyno to Kings and agreed it is low)

my car setup is here http://www.b18c5.net.

 

.....it looks like you didn't do any cam gear tuning. Is this correct?

 

Nope, no time. Had one hour and had so many things I wanted to try with the datalogit I focused on that. Used some injecor correction factors and smoothed my A/F curves.

I have stock cams and have come to decide that cam gears are borderline a waste of time for what their return is.

I'm glad somebody enjoys dyno tuning. I've had nothing but grief with my dyno shop recently.

 

Do tell. Problems with the car of the shop?

 

A nice improvement thanks to the Power FC and asahi's tuning.

 

Nice Trey hope you had fun learning about your power FC and the datalogit hardware/FC Edit Software.
Mickey how hope he will be getting his and learn it too next year.

 

Trey - do go back for some cam gear tuning...you'll find it was definately worth it for me. I pulled ~4hp higher for the entire curve by the time I was finished.

 

Nice gains. Do you have the before and after A/F graphs?

 

is that 39 dyno runs?

 

looking good trey

 

Looks good ...minus the area from 5000 - 5600.

Nice work.

 

Unfortunately the runviewer doesn't see the A/F data. I am around 13.6-13.7:1

 

yes. only did 17 today. the other 23 were from the last session.

 

I figured why stress over 100 rpms of power plus I can make it smooth like everyone wants but it loses a good bit of power to do it. THere is more area under the curve with the bump, smooth or not.

 

oh ok i was gonna say...i felt bad just doing 20 straight runs on my car...and it was the first time running it after the buildup. I still need more dyno and street time though, its not close to done.

 

i want to learn about tunning too, too bad never have chance

nice power tho, but the carve not so smooth bump for tunning

 

Leaning to tune is pretty cool, I'm still a little low on the learning curve though

 

Good gains on the midrange!

 

Good #'s!

 

With your mods did you have to add or subtract fuel? I've got a ITR with AEM CAI, JDM ITR header, T1r race cat & exhaust. I've heard that the stock ITR ECU runs rich correct? So I'll be ok (not running lean) but may be leaving power on the table?

Aaron.

 

I removed fuel but I also have Prelude (290cc) injectors. That said i am hardly using them with what i have. You will be fine but definitely are leaving power on the table

 

In your opinion is a fpr even necessary (to add fuel) or would vafc be sufficent as I would only be needing to reduce fuel (to be confirmed and tuned on a dyno of course).

 

My opinion might not be as worth as much as others but i personally don't think you wil need an FPR. If you find you are needing mor fuel I think adding an FPR and then trimming out is better than adding fuel with a VAFC but others will have better input.

I think a VAFC will give you good gains but you might look into an S100 Hondata system as well.
