S-AFC Fuel Management, 7afe options Options

[[Freemantle]]

I've recently acqiured a '95 ST as my new daily driver after some unfortunate mishaps with my previous vehicle (Honda Prelude). I've been a Honda kid since before I could drive, but I refuse to just give up on this car because it is "a 110 hp Toyota".

That being said, the Celica feels like it has no aftermarket when compared to anything I've driven prior. As a non-typical Honda guy, I'm all about keeping the car stock looking and using some shade-tree mechanic work to turn out some surprising numbers. I've got a T25 off a fresh rebuild and I'm ready to make this car a little more ballsy. I've done plenty of reading, I just have one issue.

The 7afe seems to have nothing as far as fuel management is concerned. I refuse to use an FMU (Boost dependent rising rate fuel pressure regulator) as "fuel management". It appears that the best kind of fuel management I am going to get is using the AFC hack, where I will use oversize injectors and dial them down with negative values with an AFC. Here are my questions.

A) How does the 7afe ECU respond to boost? The AFC will do nothing to correct ignition, it will just keep the car from seeing boost to dial down the map position (decreasing pulse duration to dial down the oversize injectors from choking the car).

B) Has anyone done this before?

C) What injectors fit the 7afe that can be easily obtained? What is the cc/min rate of stock 7afe injectors?

Thanks for your time.

Just a quick question why dont you like FMU? i used one for quite a few months and it worked fine but i wanted more control then i started boosting 10psi+ so i went the greddy e-manage + profec E-01 good control for a piggy back ecu.

A) not at all if you have a 94-95 st you can manually retard your timing if you have 96-97 then you need a msd retard timing unit etc. As for fooling the ecu into seeing no boost check my how to there is a check valve set up that works great and is cheap to make.

B) i think there is how to install a safc in an st

C) 4age high imped 290cc injectors as for stock injectors there like 90cc or so not sure off hand just check your chilton book or call toyota
