too bad the supercard isn't adjustable somehow... seems like it would be in the position to adjust fuel injector duty cycle, or something like that.

also remember, the stock honda injectors don't like >80% duty cycle KW said i think, so 205cc aftermarket may be a bit more powerful than "stock 185cc" than the numbers would suggest?

 

wait, so the after mods don't include the Mugen header? have you ran with the mugen header with the upgraded injectors yet?

 

leonine, I have been in contact with your shop. Hopefully they will stay in contact.

We hope that you guys will contact us to help solve your issues, because this will allow us to better understand what is going on. It seems that the exhaust setups you guys have are not efficient enough for the Injector upgrade. We are working hard to solve this problem, but it is very difficult when we have never seen this issue.

oscar is awaiting my mechanics call after he gets the injectors off and test drives it. should know more shortly. it could be a bad injector but no way to know that without sending it back to rc for testing i suppose.

 

hmmmm weird. I'm sure the T1R header has just as big of pipes as the Megan one.

 

right but you are not running a test pipe and your exhaust and test pipe are not 60mm.

 

yeah, exactly what was the confirmed upgraded injectors kit prototype install again? it was megan header + 60mm test pipe + 60mm exhaust then?

i thought i read not to touch the cat on a stock Fit, as it would run lean. as in, after-market header fine, after-market cat-back fine, but don't remove the cat without tuning AFR.

so maybe it's the test pipe that really requires the injector upgrade.

 

i am running a test pipe and am running way too rich. even in open loop my a/f is supposed to be in the low to mid 11's but i am 10.4 and maybe even lower. the AEM gauge starts in the low 10's.

 

I never had the injector upgrade. I decided to wait for the hondata reflash.

 

remember, none of us have seen a c15-16 based dyno chart yet, everything is c15-60 so far... (for all of us a/t people reading and waiting)

strange, i remember from a previous chart that the SC pull away point was about 3.5k rpms... maybe that one had more mods, rats, i wish i knew where that dyno plot was.

 

awesome. maybe the base kit will be all that i need. i would love to only have to worry about an axle back, it makes everything cheaper. thanks for the info man!

 

liking the avatar man.

everyone keeps saying that the hondata is NOT available, but i think its just that it hasn't been discussed if it IS going to be available. (feel free to chime in kraftwerks, it'll stop my thread crapping. )

i figured you were trying to stay carb legal...from what everyone is saying though, especially leonie, you may be better off with a cat or axle back and no header at all. But it seems the biggest culprit is the injectors. all this makes me wonder what the 310's on the hondata would do, but then again, its a re-amped ecu to go along with it.

 

crap. this is making me re-think my decision to go with the mugen header. and it makes sense, as they typically only do n/a stuff. (well...with the exception of a lot of their fit protoypes, as they have all been F.I.! wtf? )

so do we have to end up running the megan set up?

the other exhaust components i was considering are ones that justin also uses , (spoon b pipe and fujistubo) but sometimes its hard to get the specs on the diameter of a lot of jdm stuff.

Crap crap cuhhhhrap. I guess its going to be base kit+axleback (for looks and sound.) for me. but apparently, thats not too bad, ...and a LOT less trouble.

 

so my mechanic put the stock injectors back on and blasted it down the road and back. the a/f was between 11.7 and 11.9 which a little on the lean side but not where detonation would occur. also not sure how hard the injectors are working (>80%) so i will be monitoring this closely for fluctuations. so for now i am out the cost of the injector upgrade but at least the car is running better. seems that the ultimate cause is the exhaust restricting flow although i have a header/test pipe and the whole shabang. maybe it is the diameter or the axle back is very restrictive.

I am going to drive it like that for a little while and might deside to go with a 195cc and see if that gets me in the sweet spot of low to mid 11's a/f while still not causing any CEL. it will take a few days for the ecu to reset so hopefully by the end of the week my scangauge will say "Ready" meaning ecu completed test and it will pass inspecion which is due in a few weeks.

This has been a learning experience for me for sure. i hope i have provided some useful info for other members who are having this problem.

 

yeah, that sounds about right. as far as what requires the injector upgrade, i think its not just the testpipe/cat-delete. according to oscar, if you run the injectors, you must have a cat back and headers.

 

i can't speak to other components but if anything it is not the header but the axle back imo. even with the test pipe and header at idle it is pretty quiet. when i had the skunk2 60mm cat back i put the same test pipe on and it was not drivable because it was too loud.

so again it seems that depending on the setup you have you would either need to stay with the stock injectors, 195cc(maybe) or 205cc.

to say that the header/test pipe requires the injector upgrade i think has been proven to be an untrue statement in some cases.

I sure hope my car still has that oomph it did before when i drive it home tonight.

 

and the AFR sensor, how hard is it to install? where does it mount exactly?

 

The SuperCard is chipped with a non-adjustable program. Please do not try to modify our electronics.

not hard at all. took me about 2 hours. you can mount it wherever you want in the cockpit. you will need to have an 2nd o2 bung welded on to the cat or test pipe depending on the model you get. some come with their home made 02 sensors. i chose AEM because it comes with a Bosch wideband o2 sensor. others i saw had some home made thing. then it is just running the wires through the firewall and hooking it up.

 

Just purchased a T1R Test Pipe and T1R 50S Ver.2 Exhaust to replace my Fujitsubo one. Also added an O2 bung to the test pipe and will be installing the AEM Wideband UEGO gauge like leonine to monitor the A/F ratio.
