Quest for more Power...

[ProECU]

um, yeah, i think Adrian and i ......

LOL, interesting how you put yourself in that category... hillarious

anyway, Hondas did come carburetted, so its not of topic.
I assume its way past your knowledge on how to turbocharge a carby motor properly, so i'll put your response down to ignorance and forgive you.

so rising rate are no go's?

Are all Sard ones linear?

[ProECU]

I'm gonna throw this one out there also...

I dont think you'll need a Fuel Pressure Regulator at all for the boost levels you're looking at, i'd tune it up properly as is, and look at injector duty cycle to see if it maxes out at peak torque (around 7800rpm on a B16).
Duty shouldn't really go past 90%.

If you're then still not satisfied, either throw in some larger injectos, or invest in a FPR (or both) and have your fuel trim scaled accordingly, tidy up the tune, and away you go again.

looking at the afr posted, it really doesn't look too bad... I'd be looking elsewhere anyway



and yes, rising rate fpr's are no good

[LVNIT]

Well im telling you from when this kit was on my b16 the injectors were not giving enough fuel up over 6000, the wideband showed this.

It did not matter what i changed on the map, still did the same thing.

sax, I think thats a plot of the psi across the rpm, not afr.

lvnit, that sounds wierd, but from memory, weren't you running more than 6-7psi boost on your setup?

I really need to see a afr plot to help you more, can you datalog a WOT run as lvnit suggested?

[tinkerbell]

hey ProECU, you arnt even answering the questions kris is asking, you are simply being a PITA...

kris_ - no, there are several types, you need to specify when ordering that you want non-rising rate...

if the one todaek9 is selling is a B&M 'add-on' style, these are OK, and are linear, i have used one, but can be less reliable than the more expensive ones...

doh! not sure why I thought it was a/f... glanced quickly... your dyno print outs always look so different than out here... what's with not having torque numbers? that's what makes the car fun to drive!


honestly, with that set up, I can't really see the 450cc injectors being a problem unless you're having a fuel supply issue to them. I've tuned a 180kw b16 turbo on 450 cc's before without a problem, so I really can't forsee one at 140kw being an issue... 180 is about pushing it though.

Sorry you are right about that, I was running 11psi, completely crossed my mind

its cool, everyone should just chill.

No point to any of this.
I havent taken the car anywhere yet.

I'll leave it how it is for a week or two till i get time to fit the new clutch.
Then i'll give Dyno Dave a call and see if he can throw it on the dyno for a few hours and put a proper tune on it.
The car has more in it, we'll see in a few weeks.

Thanks for all the help guys

Mods close this thread, thanks.

I'm told you met up with Dyno Dave over at the Online Performance shop the other day.Fixup what he showed you and give Dale another go at finishing off the tune,and leave the STD fuel pressure reg alone you will never fit a better one on this setup.

no worries
Thanks for the advice.
He just told me to fix all the vacuum lines as its all comin from one source

Thanks for the help.

Will let everyone know how it all turns out

[VTi_b0i]

slightly off topic, but how hard is it to get 150kw ATW from a turbo kit for a D16Y1 civic? and will it still be reliable?
