Question for Pople w\ the supra Injectors

by **SC V6** » Wed Jul 23, 2003 3:57 pm

When u had the injectors put in.. did u have to have them "Calabrated" so that the check engine light would go off??? or did u just hook up ur S-afc or some sort of Airflow controller to make that go away? thanks

I had fuel managment b4 they ever went in. I use a Split Second FTC1.

yeah, my injectors made the computer freak out, so the check engine light is on... and I can't really even drive my car... it like boggs down if I even step on the peddle... how do i reset the ECU? I have my s-afc installed, but I can't seem to get the ECU reset

Where did you get this Split Second FTC1 Fuel Timing Calibrator ?

by **EricSol** » Fri Jul 25, 2003 6:31 am

The Split Second unit does timing and fuel

To reset your ECU disconnect the battery or pull the EFI fuse.

Nice

The second question: Where can I get Supra injectors and do I really need it? :-?

I have my S-afc II installed... and my injectors are freaking my ECU out so much, it has a hard time even reving past 2000 Rpms... the people at the dealership said that the ecu is trying to send even more fuel, rather than less.... I dunno why, I installed the S-afc II and Jim@foreign Affairs said that I should set the low fuel down about 12%... and I did, but the Check engine light is still on.. and I tried to pull the EFI fuse, and tried to disconnect my battery, but still has a check engine light.. what do I do? I have the cords coming tomorrow or sunday so I can data log w\ my laptop, but what should I do?

by **EricSol** » Fri Jul 25, 2003 12:19 pm

wait untill you can data log and see whats going on

by **SC V6** » Fri Jul 25, 2003 12:33 pm

yeah... thats what I was thinking, but i did have to drive it from the dealership home... but I don't think it running rich will really hurt anything if it was only like 10 mile 15 at the most.. but... yeah I get the cord to hook it up to my laptop tomorrow, hopefully.. then I will post what it was reading and stuff.. maybe u could help me tune it correctly so it doesn't freak out.. aahha ill keep ya posted.. thanks

I got my hook-up to data log.. and the air intake sensor was unplugged... so I pluged it in.. and my car works! awsome... anyway... What level is good for short/ long term fuel trim to be? also... knock and air-flow percent.. thanks

You want your short term fuel trim to be as close to 0 as possible. After you get that dialed in the long term will take care of itself. That will take care of your low map then all you have to do is dyno with a wideband o2 for your high map and your done. I use 12.5-1 afr, 12-1 is safer and you might make more at 13-1 but risk damage. Good Luck

Does anyone know... on the S-afc II does AFl stand for air-to fuel .... or air flow level, or something else.. please respond.. at idol on my car, its at about 5.1%

by **EricSol** » Sat Jul 26, 2003 3:33 pm

It will jump, your just averaging it.

I found that my Exhaust gas thing is going crazy too.. that 3in exhaust is making it hard for the sensor to smell the gas or w\e.. so it is setting my check engine light on... anyway around this??
thanks
Scott...
I heard that Jim@foreign was selling a "fake" one or w\e that made it tell the ecu everything's alright all the time.. but I dunno
