leonine,

I am glad that your guys at the service center took care of you. I had a great conversation with them about what the car should and shouldn't do, and what they could expect. It sounds like they did a great job, and things worked as I expected with the stock injectors. The A/F ratio is great, and you should have no worries.

You should go down the road a happy camper now.

I apologize for the trouble, and I want to let the Fit community know that we have been working very hard to make sure that leonine and others have no more issues. Of course, contacting us direct is best, that way we can rectify the situation.

Thanks for the support FitFreaks!

Leonine, you are currently running with stock injectors even though you have an aftermarket header and cat back?

Are you running with a test pipe or did you put the cat convertor back in?


I'm just monitoring your progress with great interest for when it comes time to install the kwsc into my A/T Fit.

 

Had a great talk with Oscar this afternoon. I got a Scangauge II and a Wideband A/F gauge and will report my readings with the injector upgrade and let you guys know what I've come up with when I get these parts in!

 

i went and read one the fit exhaust FAQs. stock exhaust is 48mm it says -- so no wonder 50mm doesn't have the flow required of the 60mm+injectors setup! 50mm is +8%, 60mm is +56% cross-sectional area.

i probably shouldn't have gotten the t1r header, oh well it's mine now! i might do an axle-back muffler for upgraded looks, but that has little to do with overall flow, i suspect. so, i don't plan on grabbing the injector kit i guess...

 

hey so i got the 60mm skunk 2 exhaust..and im getting headers next summer/hondata(if it is available for AT)..but my exhaust and the supercharger should be a good combo for now right??

 

Thanks so much again Oscar for EVERYTHING! keeping my fingers crossed that the scangauge tells me that all codes are gone and i will pass inspection. I'll keep ya posted.

You da man

Peace bro!

 

so it was more of a noise issue? i didn't think skunk2 would be quiet, even before f.i.

so theoretically, if i keep my cat, which i will, i should be ok running a header, new b pipe and axle back(a quiet one?)

oh and glad to hear it worked out for ya leonie! we need a full on review! and the info has been priceless! kudos to kraftwerks for sticking with us too!

 

i doubt the stock exhaust is 48. my 50mm pipe looked much larger but i never measured. but it does shed some light on the subject. If i wasn't so in love with my mugen axleback i would dump it. I wanted to get the megan 60mm mid pipe but they were on back order forever like 5 months.

Currently i am running:

Mugen headers
T1R test pipe - 50mm
T1R mid pipe - 50mm
Mugen dual axleback

I do have a megan test pipe 60mm in my basement with an extra 02 bung already welded on if anyone is interested in a local pickup. needs a new donut gasket.

 

whoa! so no more cat for you! and did you get the t1r 50s just to match the test pipe and have a nice tr1 flow, or was the wagolis causing issues in conjunction with the kit!


man this is so confusing.

 

interesting, and thanks for the post tom! do you think the power loss was due soley to you not running a header, but running a cat back?

 

so like you said earlier, having all this didn't really require the upgraded injectors? kraftwerks response to the contact they had with your mechanic and the install seems to support this.

so i guess if no injectors but a cat delete/test pipe addition, headers and axle back is ok with the base kit, we should be gravy.

i just got a decision to make now.

 

It seems that way thus far. but i cannot give the green light until my ecu passes all of its tests.

 

cool beans. anxiously awaiting the results! glad it worked out for ya man, truly, and thanks for answering my questions!

 

Ohh and by the way stock exhaust diameter is 42.7mm

 

took her to the track on friday night. im not even going to post my results. i was so mad... reason being - i found a huge boost leak the next day. I was only boosting 2 lbs at the track. Hey, at least i still beat a stock prelude by .2 sec!!! Im going back next month after catdelete/headers/hondata... hoping to break into 14's

alright, alright i ran 16.8... pretty bad. but that was at full weight, less than half boost, and AC running (it was hot as hell, i 4got to shut it off lol)
Im ordering t-bolt clamps for the whole system, cuz even at 5 psi i've noticed the Fisher Price clamps that come with the kit tend to move a little even after tightening... i've had to fix the same boost leak about 4 times now All I have to fix now is the 2 brake lines that rattle every once in a while and I'm good. When it runs at its peak, it's OH SO SWEET.

I was down at seaside heights over the weekend. Literally, every corner i came to, somebody said something along the lines of "is that a boosted fit?" or "that shyt is sweet!"

And for anyone who's goal is to beat an SI... it's possible... i raced the SI... he beat me once.... the other nine times, he finished second My friend has vids... I'll post once i get my hands on em

 

sorry about your woes dude, but other than that, congrats! and get those vids up!

 

the faq says 48mm OD twice... is that 42.7mm ID? Then 50mm is +37% and 60mm is +97% (!) cross-sectional...

 

I think the cause of the slightly lower power down low is caused specifically because of the poor flow characteristics of the stock header. I have a feeling that it probably doesn't really have much to do with cat back though. If you read into what the Jacksons have done in terms of reflashing the ecu, you will see that a lot of the adjustments they have made to the tuning are related to low rpm performance (movement of v-tec change over to a lower rpm, ignition map changes).

I'm sure the power gains would've seemed a lot more impressive if I never had a header, but I am pretty certain that once I have that and the Hondata reflash w/ injectors, I will be making a good deal more power. I'm thinking about 160 on the dyno I've been doing all my testing. Will report back once the kit has been installed.

 

16.8 with supercharger??? My mainly stock Jazz went 17.009.

 

Yay Rexxxxx....i Want To Beat Every 4door Si....grr Si's Are Not Suppose To Be 4door....sorry In A Cranky Mood Guys...but Good I Hope I Beat An Si Atleast Once..lol
