safc Options

[dan4]

i have heard a few ppl rattling on about them but someone one said to me that the safc will send your timing up the spout when it changes the afr ratio....??? can anyone explain a little to me as i dont know a lot about them and three ppl have just bought them in my area but im not so sure they work well and reliably

so you would be sure that if i connected a wideband to my car and run 17psi instead of a standard 13.8 the afr would be perfect without changing it?

why not? run too lean or rich and damage will occur either way

rich won't blow the engine... but will chew apart your cat.

.....if you run too rich you will bore wash

the object of this is not a power gain its more of a peace of mind issue

get youself a wideband o2 gauge. then you will know if you have anything to worry about. if you have an st205, then running 17psi on the stock ecu and stock 550cc injectors shouldnt be a problem.

another thing you can do, is take your car to a dyno. they will plot out and air to fuel ratio and your hp out on a chart. then you will see if the car is running lean in any way.

the worst thing to do, would be to just buy an safc and start messing around with it. there is a strong chance that you can damage the motor by doing something that you think will help it. put your car on a dyno 1st, then you will know if you have a fueling issue that needs to be taken care of. dont just buy an safc because it looks cool in the car. thats a big mistake a lot of peole make.
