apexi afc

[Black Yaris]

so I have been talkin to another tuner here in town that has a pretty sick Aveo, yeah laugh.... that is what I did, because I have driven an Aveo b4 and know how sluggish they are, but with a CAI & Exhaust then tuned it with an Apexi AFC to mess with some shit with MAP and the injector pulse, shit that was way over my head.... But this was one bad machine with minor modifications, and he said it can easily be done to the yaris even though we have a MAF instead of a MAP, it is the same concept.....
so I may borrow another buddies AFC out of his old car he does not drive anymore and try and turn my ride, it we are sucessfull, I am going to buy the AFC, and post the DIY on the tuning as each vehicle will be a lil different settings from the next.... so lets hope this shit works, cause if I have similar results has him, I may have the baddest N/A 1NZ on the road

go for it!

Yes you can fine tune a car pretty well with an AFC. It is what I used to put a MAF from a maxima on my nissan. I suggest you get a zietronix wideband kit. This will allow you to datalog your AFRs as well as others like throttle position etc. You can do a very good tune when used in conjunction.

[Black Yaris]

well I don't know what the hell I am doing with an AFC, but I have a few friends at local shops and a Dyno that are more than happy to help :)

[Nabisco]

Even better. You will get a print out of what you are putting down to the ground.

[Turbo&Auto]

afc only tunes af ratio. You need to tune VVT'I and timing as well ;)

Oh I will have the dyno sheet from the tuning of when this is done

I understand the AFC only does the air and fuel, and a VVT controler would be most bennifical..... but no one I know just has a VVT controler just layin around... but I can get ahold of an AFC, if I have good results, then I plan to run it in conjuction with a VVT controller and retune....

I just hope all this shit works cause it would be a fairly inexpensive preformance upgrade

exactly.

the afc will only let you lean/rich the fuel mixture by adding/decreasing % values at 6 points on the rpm scale(i think it was 6 :redface: )
is the same thing as the simple emanage but the emanage with the support tool gives you a 16 x 16 grid for specific "tuning".

i'm not sure what your friend did but for a n/a vehicle is kind of money wasted. i used the afc twice on civic turbo-homemade kits and it did what it was supposed to but never to the full extend of a true tuning device.

the only way the afc will be of value is if the ecu runs really rich and you can then take some fuel away, then you will see an increase in power but not much really.

good luck man!:thumbsup:

[Black Yaris]

like I said.... this is an experiment.... he works for a reputable tuning shop in Columbus, OH... so I am sure he had an AFC laying around, and he was doing the same experiment

Hey ~~ Black Yaris
I have a SAFC 2 too it was from my old ECHO
but i still not installed it because i don't have the ECU wiring diagram for
NCP9X Do you have it ??? Thanks

[Turbo&Auto]

I wouldnt expect more then 5-10whp at most.....

nope not yet.... that is one of the things he is having his Toyota guy research.... and ain't there some crack for the ECU or something..... I fucking don't know.... he is doing all that, I don't know shit when it comes to motors

[Black Yaris]

I would be happy with that

I have been gettin 5 here 5 there.... all these little things are starting add up, and if I get them properly tuned together it will make them most efficient

5 here or there, dyno proven?

[Black Yaris]

no, not 5 each... I am saying with all those added up... I am probibly lookin at 100 at the wheels, with all the bolt ons... 105-110 after tuning... it do not find this to be too unrealistic

[Turbo&Auto]

you'd be surprised how this motor is un-affected by mods. Goto a dyno :)

just looking at this post here I do not think I am out of line with my #'s
but I will be doing a Dyno b4 and after to give hard #'s so I can post dyno results... so there will be NO estimating on my behalf, only the the Dyno will tell

[Turbo&Auto]

That proves my point exactly, nothing gained. AND its lean as hell just like I've been saying for awhile now with the Toyo DBW cars.....

[Black Yaris]

Grrr.... those dyno's are for just an intake install, for what 2-3 WHP? and running lean...
I have a lot more than just an intake....

[Turbo&Auto]

It was no gain and you risk hurting your engine. Given you have a SAFC to adjust, I would make sure theres a wideband in the car to reset the ecu after it relearns around the safc. I have no experience in this at all so dont take my word......Only used a SAFC for about a month on my Turbo'd Matrix......

[Black Yaris]

I have no experience with it either..... but this guy does.... and he is running it fine on his ride.... like I said from the beging... experiment..... if it works YEAH, if not, no big deal, at least I tried

[joey1320]

slowmotion is a great shop,hopefully they can help out with the afc/dyno/tuning. good luck!

[lostmind]

Black, I hope it does work out for you. Can't wait to see the results.

Good luck!

[Turbo&Auto]

It was sarcasm mang ;) I had one in my car for almost a month, had to reset the ECU 3 times, it kept changing around my settings. PLUS it cant tune timing. I cant say enough how this will be benificial!!!

[Vic-2NZFE]

I would be happy with that

I say go for it, if its pretty inexpensive and your friends want to give you a hand then why not. good luck with the tunning :thumbsup:

Make sure to post a DIY and the tunning itself with some pics!

[Sleeksedan]

BLACKY you rock your trying to move our sport into the future. DON'T take any flack from anyone. People like you will always be picked on by pussies who are too afraid to try. I installed the AEM intake and I chassis dyno'd my sedan at MOPAC (the big performance guys out here) and over the 5 runs (that I could afford) My fuel leaned out and I gained a solid 2 whp. And that's shitty AEM technology. So for all the haters that say "why mess with your lil go kart?" GROW SOME BALLS OR TAKE YOUR YARIS BACK AND TRY TO GET YOUR LEASE SWAPPED TO SOMETHING ELSE!!!

I'll get my dyno sheet on this thread A.S.A.P

[Nabisco]

Someone spends money to get results and shares it with the rest of us and you have to poke fun.

[Ran Kizama]

Don't forget that my Yaris dyno'd at 97.7WHP with just intake, header and exhaust. I still have my Blitz R-FIT that I never got around to installing or selling so I may go ahead and do that.

That proves my point exactly, nothing gained. AND its lean as hell just like I've been saying for awhile now with the Toyo DBW cars.....On that piticular car it actually riched up the mixture if you look at both graphs. Stock was near 15:1 at WOT,on the cold air graph it actually gets richer as the rpms go up. Its really not that bad at all for no tuning. Now if it went the other direction on the graph I'd be scared. I'm interested to see how a short ram like mine affects the A/F.

I believe the stock dyno is on the right ;) The CAI dyno looks wavy as hell, like its leaning out all over.
