safc2 tuning

[Jiggyfry]

whats up people. im a noob and was wondering if anyone could help me with some safc2 tuning on a na ka24de?i just got one, but i lack an egt gauge and a wideband o2. has anyone got any experience with this tasty toy?

[Jiggyfry]

ok folks, anyone got any tips for tuning it? i know i should have a wideband o2but i don't have the funds for that yet. i will be getting one in november but can i do anything in the meantime?

[Kenrik]

you can take it to a dyno and have a pro do it... I don't think many people try to do it themselfs

[Jiggyfry]

i don't have access to a dyno. thats my problem.there used o be one near but they closed about a year ago

[fbodtrek]

you need a wideband, wihtout it, you're just guessing A/F ratios.

[Jiggyfry]

how much power can i expect from tuning this?my guess is 5-7 but i just wanna make sure.

also, what do you people think of nos on a ka24de?

[Florida240sx]

Any kind of tuning you either need to be on a dyno or have a wideband. I wouldn't want to give you false information that could blow your engine.

[Jiggyfry]

thanks for the info guys. i knew i would need a wideband to be accurate but i figured there was a sort of "base" as to where i should richen or lean out.

my safc is not adjusting the a/f ratio right now, only monitering. how much shou;ld i pay for a wideband?

[Kenrik]

I don't like NOS at all unless you are using it to supplement a Turbo... after you pay for all of the NOS stuff you might as well have gone with a cheap turbo (not in quality but in setup) and that power is always there... no need to pay for a 'Refill'

A small turbo setup will run you around $1000 and get you a lil over 200WHP... that's the about same as running a 75 shot of NOS but all the time... power is always there..

[Jiggyfry]

i'd like to keep the ka and turbo it but the amount of parts for the sr are amazing. any good companies for turbo's for the ka?

[Kenrik]

Greddy has a bolt on turbo kit with eveything you need for $3500

if you're not looking to buy a kit then just get a T3/T4 turbo and buy a manifold for the KA... lot's of info in the KA-T section of the site..

if you're going to be running an SR20DET then well... you would not need a kit I still prefer the 2.4L KA (iron block) to the 2.0L SR

[Jiggyfry]

what is your 1/4 mile time?

[Kenrik]

Mine? lol 15.2... it's still N/A i'm in the process of getting my KA-T together

[Florida240sx]

Buy from our sponsor IAP. 3200 for their kit. and you already got a safc. Only other thign you will need is a wideband so yu cna tune yourself and a heavy duty clutch. at 7lbs i got about 230hp.

[Jiggyfry]

thats pretty good man. mine was 16.1 with an exhaust, header, anf intake. a month later i yanked the engine and completely rebuilt it. also i did a port matching and slight porting of the intake and exhaust side. finally i added the safc and a stage 1 act clutch. my most recent 1/4 time is 17.2!

knock sensor?

[Kenrik]

God dam 17.2 is like a Civic time... that's way worse then stock... stock on a 240 is 16.5... either you are an awful driver/launcher or there is somthing wrong with your car... I plan to be well into the 14s with my small turbo kit Possibly break into the 13s..... a few years, a few engines and more then a few grand from now this will be a 10s car.

Mine? lol 15.2... it's still N/A i'm in the process of getting my KA-T together

15.2?? lemme see a time slip and a list of your mods....

[lrb_2000]

I second that request lol.

[sunnys14]

i think i saw in some posts that he had a SOHC motor... 15.2? ummmmmmmm.......

[lrb_2000]

maybe he meant 16.2 ...

anyways, you can find widebands for about $300. PLX300 is a good one, Innovative makes them also.

oppsss typo... yes 16.2 lol it would cost a a lot to get an NA down to 15.2

i hit low 15s while NA no problem... didnt cost me a whole lot either.

[miked808]

Damn Kenrik when I saw your time I almost wet myself. Stuck on 16.1 myself.

[lrb_2000]

can't you just completely strip out your interior... where you have your dash, a seat, and a shifter lol... tires with some traction, and basic mods and run pretty low 15s? I thought I saw someone say they ran a 14.8 wiht a stock ka completely stripped interior... My car weighs freakin 2810lbs. lol.

I run dope on my car personally, along with Header, dual 248* cams, CAI, and 2.5" exhaust with a resonator for a muffler (actually sounds good). This is in an AUTOMATIC 93 fastback. I ahve yet to get walked by ANY N/A 240sx 5 spd car (this is motor vs. motor). I have raced quite a few other 240's as well. With nitrous, my car runs mid/low 14's on a 50~ shot. I ahve jets to go steadily up to about 90 hp, I've just been lazy to tune for them. The KADE LOVES nitrous oxide. Yeah, with turbo you'll ahve power all the time, but your drivability in the twisties will suffer slightly (if that sort of thing matters to you). NAturally aspirated throttle response is generally beter than turbo setups. And if you DO run into a quick car, jsut crack the bottle and spank that arse. As for tuning, I'm still runnig a completely stock Map, but I'm going with a AFC pretty soon myself, I have a few holes in my powerband I'd like to smooth out.

[miked808]

Is anyone running High Compression and Nitrous?

[InsanityInc]

i hit low 15s while NA no problem... didnt cost me a whole lot either.

Yeah, but you have the right number of cams

[240DRFT]

Yeah, but you have the right number of cams

lol hahaha oooohh burn on kenrik jk

[Kenrik]

I like my single cam!! no SOHC love? next you're going to tell me fastbacks are better... Psst... Go away you.. :P

[lrb_2000]

they are haha...but I had a sohc coupe, and loved it.
