safc/safr

i felt like i should ask the n/a guys here before i go to the tech section... which one is easier to install, safc or safr... also, does anyone know what i will be doing when i am installing this? will i be cutting wires? which wires? etc? i'm thinking of ordering one of these at the same time as the exhaust, installing them both myself to save money, and then get the safc/safr dynotuned. what do you think? how much should i be looking at to get this dynotuned (am i spelling that right?)... and how long will it take to dynotune?

also looking forward to hearing bout that egr mod thingy... i'd like to also do that one before i get my car dynotuned.

comments? ... anyone...

would you suggest one over the other and why?
If you have a obd1 Supra with the rectangular AFM, I can give you wiring instructions for the AFC. I don't care for the looks of the AFC as well as the SAFR, but i got the AFC because i was familiar with it, and knew how it worked. For that reason, I would recommend the AFC. :D I just mounted mine in the flip-up compartment between the seats so it's hidden.
Here is where I put the AFC. :D
Tight install man.

this question may be way out there but do u kow what HP gain i may be ble to get outta a early MKIV with the SAFC?? thanks man. Nick
Oliver (where the hell did he go?) got ~200rwhp using just a intake, exhaust and a AFC.
thanks but i went with the afr... by the way, oliver just posted again recently in one of the other forums (tech i think)... oliver said something about getting 175hp before the techy leaned it out a bit and then got 199hp...wow... in the import tuner mag, they got ~5hp and some torque back too with the afc.. i don't know of anyone with the afr on their n/a... but i'm gonna do it.
ok the afr is in... now how much am i looking at to get it tuned on the dyno? so far all i could mess with is the idle and the response... i'd like to get it dynotuned... or is there a way for me to tune it myself (doubt it)?

since it isn't tuned, my car did not gain or lose any power right?
Wishlist,are you obdI or II? Going with the console install? Oh yeah I think Oliver is posting on www.neforums.org mostly now.:D

...anyone?...
Best bet is to see what Oliver did. I don't have any experience tuning the na. He'd know more than anyone.
Hey guys.. sorry for the late response... won't happen again ! :)
Well, I went with the S-AFC because I was more familiar with it.
After I installed and took it to the dyno. We first made a base line pull, and I put down 177rwhp with catback exhaust and K&N air filter. Then the guy at the dyno made 3 more pull and adjusted the S-AFC. The car ended up with 199rwhp with tuned S-AFC.
All the settings are set to 0 upto 3,000rpm then the S-AFC starts to lean out the car because it was running rich.

*wishlist*supraTT: I'm no sure about the S-AFR.. but with the S-AFC if you install it and everything is set to 0 is like not having it at all. I would thing that it would be the same thing with the S-AFR but I'm not 100% sure.

I would not try to tune the S-AFC or the S-AFR on the street or by yourself. Take it to the Dyno and have them do it because they use sensors to see how much rich or lean the car is running so the can adjust it to a save level. That's what I did because I'm starting to learn a lot of thing and I didn't want to damage my engine :D

I hope this helps. Le me know if you have any more questions..
Take care.

DAVE:

Welcome back Oliver-

Glad to see you back posting again. Just posted in Tech Section. While all cars are a little differenct, care to enlighten us about steps, techniques used while your car on dyno? Would new AEM(?) computer be better and eliminate need for Safc? Thanks
i m pretty sure that s-afc stands for super air flow converter... to find out what it does, look it up on mvpmotorsports.com
Re: DAVE:

The AFC adjusts your fuel mixture (rich/lean) at various different rpm points. It allows you to fine tune your fuel mixture to get more hp.

The 4 switches are for my NOS setup, yes the console closes. :D
