well guys i just tried sodering the air flow sensor wire and i still got no reading so after that i began to get angry brought the afc inside to make sure the connections inside were all right they seem to be... put it back together n re hooked it up still no dice very ****ty... so now i'm out of ideas I wonder if it matters that those wires were the only 1's soderd .. if anything i'd figure they would be the most important ones anyway... thus why it's so ****ty oh well i'm starving so i'm gonna go eat while i ponder this 200 dollar investment....and the thoughts of a toliet!!

 

sorry to hear that dude. all i can say now is to double check all harnesses to make sure that the wires are connected. they might have been pulled out a little if you've been tugging on the wires and not pulling from the harness itself. and also pink goes to the ecu and orange to the sensor. probably all redundant to you, but hey, who knows? also, the wires on the afc is a little thinner than the car's wires. could be a bit on the cheap side.

 

Hmm dunno man checked all that my lastideais to soder everything even then i don't think i'd see the air flow reading unless it needs a really good ground source ya know... it just really pisses me off to know I have it but yet it won't function like it should, then to know in the end i may have to end spending a few hundred more for a new 1 guess I could wait till I have the new one in my hand before removing the old one... Blahhhhhhhhhhh!

 

Hey guys whats goin on well heres an update for ya from what i hear on a karman setup you very rarely get a air flow reading.....this was on apexi's F&Q pretty strange huh i dunno how one goesabout tuning that then....just figured i'd let u guys know

 

well mine reads like this at idle:

rev 705
thr 0.0%
kar 17 hz

thats with the monitor setup for 3 readings for rpm, throttle position, and karmann readings. at cruising, karmann reads around 100-200hz. it changes with rpm and speed. i haven't read the faq, but thats what mine does.

 

ic ic aight once again rhyz your the man to answer all my questions thanx bro

 

Hey rhyz does your KAR read any higher then 100-200 like when you punch it... i think at idle i'm runnin 20-22 tomorrow I need to really sit down and do some tuning prolly when I finish my throttle body.. depends on how much time I have before the girl comes over...

 

well my idle is lower cuz i changed the size of the hole of the restrictor. could be the reason why i'm getting 17hz instead of your 22hz. just as long as your idle rpm is about 700, it should be all good. if you're getting a karmann reading, i see that your safc is working properly now.

yep, when you punch it, it should get pretty high. i'm not really sure cuz i hide my safc, so i don't look at it everyday anymore. it's never in plain view unless i plan on tuning it. my friend got his safc stolen last week. sucks for him. all that really matters is that when the throttle is opened up, the hz should be higher, and vice versa. maybe i'll get you numbers tomorrow.

 

oh yeah, if you got an a/f gauge hooked up, you can back out the mixture screw on the bottom of your MAS. there's this circle with a lot of gray or black silicone on the bottom of the sensor. you can dig under the goop and unscrew the screw thats under. not all the way out, but just so that it's not blocking air passage anymore. then you can compensate with the safc... compensation shouldn't really be more that 2-4% though.

you can check the link for some pics.

 

Ahh thats where that screw is located huh LOL I saw that today when i was working on my car and wondered why it looked siliconed ... I said "I didn't do that" anyway ya it's working right it actually wasthe whole time i just didn't realize... LOL I'm still wondering about the Dec. -Air settings and the throttle high low setting ....Hey you think that i set my NE-Point from 2000 up to 5500 rpms? in 500 increments is bad?

Figured it'd be nice through the powerband, nice build up throughout it ya know also whats our throttle sensor type and graph scale.. sorry for the questions man.. you've been a great help thanx and Ooh so far car feels nice ... thank a lot man i'm curious to what your numbers are even though each engine is different it'd still be good to know.

Hmm i wonder how the gains are with that hack grrr i need to invest in that gauge do you suggest it just cause it'll be easier to tune with that done ? cause i noticed Road Race mentioned it as well...

 

damn, replied last night but the server was busy...

you need to cover the same rpm range as the stock ecu because all you're doing is modifying the stock fuel maps, you're not making new ones. my rpm points are 1k, 2k, 3k, 4k, 4.5k, 5k, 6k, 7k. also, being able to adjust at 1k helps adjust fuel at idle.

the dec-air setting is for cars with a hot-wire sensor and turbo'd. we don't have those, so this setting isnt important. i'm not sure if they benefit turbo'd cars in general tho. something about correction for turbo cars venting their bov's into the atmosphere.

my hi and lo settings won't do you any good because i don't really see much gain with the restrictor plate mod yet. i still have some sort of restrictor because the stock fuel system doesn't seem to be able to compensate no restrictor plate even tho i have an safc. but my hi settings are around +28-30%, and my low settings are around +38-40%. there is a good bump in power in the top end, but kinda laggy down low.

our throttle sensor reads 0v at no throttle and 5v at WOT. so i think you want the setting with an arrow pointing up.

the jumptronic a/f gauge that road race mentions isn't for sale anymore. i found out why. because the jumptronic used a part from radio shack that is now discontinued. i found plans for making your own that used a similar part from another company. maybe costs around $60. can't remember cuz i made it a while back. but it has a digital display and is backlit. much more accurate than the blinky lights tuning wise. somewhere on the web, someone sells the same thing i made, except in a whole lot of different colors. and yeah, you need it to tune. basically because you want to maintain a certain a/f ratio throughout the whole rpm band. i have mine set for .88v-.92v at WOT. but actually setting your lo settings is much more important just so you can get the car running.

i'm set to get a rising rate fuel pressure regulator and a header next month, so i plan on running no restrictor by then. much later will come the throttle body. i might finally hit the drag strip in the beginning of may so we can see if there is any good gains to be made by then.

don't plan on tuning your safc until you get your a/f gauge. otherwise you won't be able to tune at all. read up all around the internet because it sucks to blow your engine because you overlooked or didn't know something. otherwise, have fun...

 

as for those karman numbers, it gets as high as 719hz at WOT in the beginning of the powerband, then it tapers off to 500-600hz after 5k. probably just a limitation to the camshaft. how high does yours get?

 

hmm aight man i'll def take all that into thought, ugh ya i looked at the restrictor plate couldn't really get at it.. but i did get at the screw n adjusted that... as far as my karman prolly reads up to 700 but i think more towards 500, i'll have to check today when i go out... but ya i def want to invest in a air fuel gauge when i get the money to for now my throttle body has a nice lil bore and i installed my other tach i need to get my camera working again so i can post some pics for ya.... not sure i may set my rpms down lower to tune at idle but i dunno yet i'll have to see .. I really need to get in some dyno time ! thanks again man talk to you later.. blah maybe just maybe I can get my straight pipe done today.....

 

Hey guys well no straight pipe today but I did get the Air Fuel gauge I have everything hooked up red to power black to ground nowi have a violet wire for the Oxygen sensor wire anyone know where on the ECU that wire is located? lol my glove box once again is in my seat so hopefully someone can give me an answer.. Have to getout the Roto Zip as well found a nice place for the gauge to rest ...

you want to look at the 2g wiring harness...
