I'm wondering who here has used the MAFT-Pro for its PT tracking functionality. It requires that the stock ECU operate in open-loop at all times (accomplished by cutting the narrowband O2 signal line), and relies on the MAFT-Pro to monitor a wideband signal and manipulate the AFM signal that...

While my car has had plenty of strange problems, this is the most mysterious one I've run into. First, my car is running MAFT-Pro Speed Density. It has been running well with the setup for perhaps 1,000 miles, including a 500 mile road trip that was nearly all cruise and did not show this...

Hey all. My car (mods in image below) is apparently running lean at idle...with the ECU performing maximum fuel dump (5V at Vf terminal). My LM-1 wideband showed readings from 15.5 to 16.5AFR, or thereabouts, at idle when the car is fully warmed up. I tried cranking up the base fuel pressure...

Hey all. My car is sporting a high idle (about 950RPM when warm), and I'm confused about how I'm supposed to adjust that. I figured the TPS wouldn't help, because it's sending IDL to the ECU, and as far as I know, the ISC is on its lowest setting when the engine is not under any auxiliary load...

Sorry for the double post--the below is on SF, but the issue is still an enigma despite about 50 people viewing the thread. I apologize for the length, but please help! Hey everybody. I have an 88T that is acting insanely strange. Tonight, I drove 15 miles or so to a movie theater (meeting a...

Hi all. I'm on my way to owning a series of these great cars as many of you already have; first, my 1992 non-turbo, and now, a pretty well-stocked 1988 Turbo. The link to the auction I won is below; let me know what you think about the car, and the price paid for it. 56K-user warning on the...

I'm about to buy my second Supra, but it's burning oil on startup and deceleration. The piston rings are brand new, and the turbo was just rebuilt, so I'm pretty sure the valve guides/stem seals are bad. I have heard that the head does not need to be removed in order to replace them, and am...

Hey everybody. In my N/A, the accelerator is reasonably loose/unresponsive compared to other cars. It's not terrible, but because something like this seems as though it would be pretty easy to adjust, I'd like to fix it. I've looked at the accelerator cabling connected to the throttle body...

I recently had a minor accident during which my car slid out of control, into a curb. No structural damage, no airbag deployment, although one tire was torn by the rim. When I got the car home, I pulled the EFI fuse to see if the computer just needed to be reset; sure enough, I got my key...

Hey everybody. I've got a 1992 N/A with severe oil leaks (front/rear main seal, and oil pan gasket); thus I'm going to have to pull the engine in order to fix them. While the engine is removed, I can't bear reinstalling the first catalytic converter; of course, it robs power, but it also...

Just wondering how much the N/A gas tank holds; I suspect it is not the 18.5 gallon figure I've seen before (might have been the turbo). Does anyone know the exact figure? Year is 1992, although that's probably not important information. Thanks, -- Scott Goodson

Hello everyone. This is remotely off topic, but I think a bunch of people will enjoy it regardless. I've made a time-lapse video with my Supra, along four California highways, and surface streets. It's entertaining to watch, because given the fact that I'm driving a Supra, I can easily manage...

Hey everybody. I've read about the SOGI AFM mod, and it seems that hundreds of people reference it all the time. (It's here BTW: http://supras.com/04/resources/index.php?id=16&q=AFM) I've looked at my AFM, trying to locate the "black plastic cover." I've found something right on the top...

I've been under the impression that only some Turbo cars have the Sports Package (which of course includes TEMS, Targa, ABS, LSD, and rear spoiler), meaning that if you see a car with a rear spoiler, it automatically is a Turbo--but you might have a Turbo without a spoiler. Is this correct...
