safc setting on ca18det 400cc inje

[alenomenio]

I Installed the safc in my ca18det but i have a problem setting it. it has 400cc injectors, garret T3, performanced ecu, etc,. somentimes the car goes ok, but often it seems to have a problem with the fuel, overfueledcan anyone tell me what do i have to do setting it correctly, 'cause i tryed giving it less and more fuel, what is the correct setting?need help

Ditch SAFC

[ca18detgabby]

WTF is a "performance ECU" (95% sure that is your issue)

400 CC are really close to stock specs..... less you are talking about some 450s or 460s......

I would look else where but the SAFC isnt going to be the issue here.

with 400CC you shouldnt even really need a tune.

gabby. dont try to help someone by making them feel dumb and just being a complete *****. you not sure about anything because you aren't used to the terms he uses.

just because your the biggest post whore on this forum doesnt mean you always know what you are talking about.

wow.... never said i did........... "performance ECU" means alot to you right?

how about you diagnose this issue?

If I felt the need to degrade anyone, it would have been far more abrupt and over the top. It isnt an issue with terminology it is an issue with knowing what they person is working with.

"your the biggest post whore"dam in a forum that gets little to no action and someone like yourself who pops up once ever 3 months or so..... sorry for being active member. Ive been wrong douzens of time and never afraid to admit it, but for ANYONE to help him.... they are going to need to know what "performance ECU" means.

PS 90% of the engines come from over seas these days with tunes from millions of different shops and none are for a stock tune. This is been a fail point for most of the people who have been attempting to get their cars running. It could be a MAF issue, a vac leak, a sensor, or a coil pack. HOWEVER, knowing what you are trying to fix before throwing money at it is usually helpful.

I'm going to have to agree with Gabby. What makes your ECU a performance ECU? Is it chipped? From who? For what?

Details will help us help you.

[sydwayz]

what safc r u using? 1, 2, or the neo? i have a performance ecu on my car chipped by me and im running an safc neo and 550cc injectors. i MIGHT be able to help since not many people on here like the poor mans tuning box.

ch187: Chill out dude. There was nothing bishcy about what she said. She was simply trying to help...

[themadscientist]

I post more than she does, am I a whore? Wait, don't answer that!

[ch187]

its just irritating to see someone who is obviously new to the whole thing. he had sub-par information for the question he was asking. and instead of saying

"WTF is a performance ECU?" im 95% sure that is your problem.

which would probably make the kid think he has a fubbard ECU and go waste the money on a new one. just because he doesnt know any better.

wouldn't

"i have no clue what you are talking about performance ecu. your going to have to give me some more info so i can make an accurate and helpful diagnosis."

because honestly, i cant diagnose it. and i wont go saying im 95% sure somethings wrong with the vague description he gave. it would make me USELESS as help.

now if he were to explain some symptoms more clearly. tell me what he has done to the in terms im familiar with. and i can say hey! ive had that problem. this is what you have to do to fix it

then no.

i cant.

i apologise for being blunt and opinionated. its probably why i keep my mouth shut.

and i am an active member. i just dont post just to post. nothing wrong with post whoring. as long as you dont mislead someone just to make yourself seem more helpful or smarter.

im on the boards everyday. i read more than i type. try it sometime. you'll learn a lot.

I would look else where but the SAFC isnt going to be the issue here.

how do you know this? it could very well be the problem because people like to mess with things. messing with a few buttons on a screen is a lot easier than messing with the ROM image on an ECU.

Quote »There was nothing bishcy about what she said. She was simply trying to help... [/quote]ok maybe she wasnt being bitchy. but i hate when people think they know it all. in this case the ONLY way to help this guy is to ask questions. only questions. not make assumptions about whats wrong. to early. how can you be so sure about something when you dont have a clue about what the hell he is talking about.

honestly. it could be just a boost leak. dont make the kid waste money on an ecu when it could be a blown hose clamp or some fubbard adjustments in the safc.

thats all. maybe i over reacted. but i know if i were in the kids shoes, newb, looking at gabs post count saying "man sounds like she knows what shes talking about" and if shes so sure about my ecu being the problem. chances are i would look into a different ecu. just because thats the way some people are.

When was the last time you heard of over fueling issues due to a SAFC?

last I checked(only used a few of my friends), but SAFC are good for adjusting input and output values..... with injectors you cant force them to add MORE than they normally do, only take away.

[themadscientist]

what do you think happens when the SAFC lies to the ECU making it think more air is coming in? It increases the injector pulse width. That is also how it takes fuel away, it shortens the pulse width.

[ca18detgabby]

BTW you made a ton of generalities, assumptions, and leaps......

there are people on nico with thousands more posts than me saying stupid **** all the time. Post count really accounts for little to nothing.

I didnt say put your ECU in the garbage can, but WTF means what the ****.... as in what is that? hell for all I know "peformance ECU" means a power FC or Mega Squirt. I dont know what "performance ECU" means and thus need better info.

Im getting real sick of the number "tuned" ecus I see floating around forsale and then people getting them and complaining about them not working......(why Ive had 5 emails about the spare stock ECU I have in the last week or so). The have been linked to more than a few issues with fueling and millions of other issues due to MAFs and timing.

I suppose I could sit back and not post...... when I do I will just make much more broad assumptions and go in to it assuming that the person is clueless instead of asking questions and trying to help...... wait isnt that what you did?

[RS12Turbo]

mmmmm, anyways and to keep this thread on topic.....have you gotten it dyno tuned? Because you can't put in the same afc numbers as someone else with the same mods and to expect everything to be perfect

[themadscientist]

both of you need to chill out, right now.

[boost_boy]

Hello my mean and nasty CA brethren. You all suck . All of your cars are slow and don't run right and I hope they all overheat and mix oil and water and then make your car smoke and kill mosquitoes which means no need for bug juice this summer (get it). And if you don't, oh well...... So again, let's get back to helping our poor SAFC user, please. Anyone wants to hold hands with me ?

[drifting circles]

I hope mine doesn't. Since you built it>>>

[themadscientist]

Dee

That's not my hand

[ca18detgabby]

That's not my hand

love handles getting bigger eh?

[float_6969]

This post almost belongs in gen chat it's so far off topic.

I wonder what the chances of getting this thread back on track and helping this kid are?

[themadscientist]

how do you know it's overfueled? Often ignition problems are mistaken for fuel problems adn they are also more likely to be intermittant like that.

[alenomenio]

sorry,, u r right.. i had the wrong information... i ve got the ecu from ebay' actually from JPS.. they say it is tuned. i dont know what part was modified. i also changed the injectors for 440cc..i tryed with a T3 turbo.. , apexi avcr, safc 2..the problem here is: i set several times in several ways, the closed one was 1000rpm -25, 2000 -20, 3000 -10, till (gradually)6800 +20 and the car goes very well for 2 miles and after that the car fails, feel like is overfueled 'because it smokes a lot, so if ia change the setting 1000rpm -30 to 6000rpm +10 or less, it dies on 3500 rpm... i mean it stays there..what do u recommend? should i get a new ecu? which one? or is the safc setting incorrect?

thank u for responding...

[Buddyworm]

First of all you gotta figure out exactly what the ECU was tuned FOR. Only then can you even begin to d!ck around with your SAFC. (Personally I'd ditch the SAFC all together and get a proper rom tune from somebody who knows what they're doing.)

[float_6969]

If you've read the stickies, the best route is to get a basic rom tune for your particular mafs and injectors, and using the SAFC to fine tune from there.

You're chasing your tail w/o knowing what that chip is tuned for.

It also still sounds like you've got some sort of ignition problem, or maybe a bad engine temp sensor since it doesn't start posing a problem until it's warmed up.

Maybe I mis-understood...

What you said sounds like the proper way to do it. SAFC is a great fine tuning device.

[float_6969]

The main problem with trying to fix all of the fueling with the SAFC is that it can screw your timing values up, and quite possibly, for the worse.
