well, i just finished up my install on a set of ITBs i picked up on friday. The car now idles really low and is running super rich................i have an S-AFC as well............can someone tell me where to go from here????

Update 11-1-04: I have some pics up of the ITBs and the Intake Temp sensor.......still in need of help.............

did you re-tune the safc after you installed the ITB's

 

i am in the process of doing that as we speak.................i am leaning it out accross the rpm board and it is still running very rich................also, the idle is a little funny cuz its popping a little bit when it idles @ 1000rpm..............i have leaned it out -12% for lo-throttle....................this is were i stand right now.........anyone kno how much i should lean it out???

 

i don't even know if this would help, just an idea, but would an adjustable fpr help out any?

Man ...get that thing to a dyno or at least someone with wideband tuning capability if you want to tune it anywhere near safe or properly.

yea, that will be a process monday

an update tho............we got it to idle right by adjusting the throttles..................but, its still runnin a lil rich and i have a feeling that its will throw a code once it drives out on the street

also, its not using a IACV..............could that be an issue as well?? also, i have the MAP plugged off as well.................anyone help on those two???

 

Without an IACV I would assume that would be a problem. I havent seen or worked on ITB's but I have thrown the IACV code to have an erratic idle.

 

uhh yea your gonna need the map sensor man.

 

we need pics dood....

and you need to syncronize the butterflies i hope you did that.

 

Sorry this isn't a helpful post...but...got any pics? SOHC ITB sounds sick!

 

i will have some pics up later on tonight

i have it and its blocked off, but there is another sensor that used to go into the intake..............what should i do with that one??? its just hangin right now

 

No MAP will contribute to your irradic idle problem greatly...as well as drivability. Get that thing hooked up and then see where you're at.

 

yeah you need to put the MAP on one of the TB, or if you can run 4 vacume lines from each of the TB to the MAP (maybe it would read better). And the other sensor that you are talking about, is it a TPS by any chance?

 

the sensor that im am worried about isnt the one that would bolt onto the top of the throttle body. Its one that would be the intake piping that is inserted into a rubber grommet..............................

also, (this is gonna get me flamed) my buddy has a wideband and datalogger. When tuning a S-AFC, the + sign is goin to be rich and the "-" sign will mean that u are leaning it out................need that clarified

 

that's the Intake Air temperature sensor. If you unplugg that, then yes computes is going to run little bit on the rich side *safe mode* to prevent detonation incase it's really hot outside.

And on AFC I believe if you go + you add fuel -you take it away. DON'T **** WITH IT without a wideband

 

without the map it is going to be way rich, lo vac=rich.

 

i have the map running off of a vacuum line thats connected to the ITBs................should i try to re-route it to another source??????

 

it should read from behind the throttle blade

 

post pics of itbs

 

What ITB setup are you running?
Can you rev the engine freely?
Any CEL's or running in safe mode?

 

sorry y'all....................pics will be up by this evening

soo far, it takes a little bit for the car to idle right. When it first starts up, it idles low but as it warms, the idle is normal..........................

also, i have come up with some possible solutions to cure the rich problem b4 i go to the dyno in a few weeks. Lemme kno if this will help at at all:

running a higher octane gas, plugs that are about a step or two hotter, and a slighty advanced timing.........................oh and the biggest fix: HONDATA!!!!!!!!!!!!!!!

 

bump it up...............still need some advice

 

I don't think I can give you any information until I see some pictures of this. Sorry.

 

lol..

pics please? No MAP sensor = no way for computer to measure air density/speed/etc.
