safc2, 7afe? Options

[Bitter]

does the apexi safc2 work with the 7afe? and do i need anything besides the unit itself? i might be able to get a slightly used one for about $150, and i'm wondering what else i'd need to make it work, how hard the install is, and what sort of gains i *could* see with the 'bolt ons' i have, those are listed in my signature. i supposed the best benefit of it would be improved fuel milage.


now, being a 93....i really dont have a good way to monitor the a/f besides my fluke meter hooked to the ox1 on the diagnostics port. but the stock O2 sensor is of course a narrow band sensor, by watching the O2 voltages could i equate those to a/f well enough to get a decent tune?

fuel economy - i'll be taking fuel away during high throttle.
reliability - i wont be going leaner than 12.5:1, initially 12:1

i dont see how taking away fuel during WOT would hurt fuel economy and how leaning wot to a safe ratio would hurt relability. just becase others have damaged things with a safc2 doesnt mean i will. the difference is this....
1. i have a good understanding of knock, AF ratios, EGT's, fuel maps, and how it all relates.
2. I'm tuning it myself, so if something isnt right I can fix it ASAP
3. I'm tuning it myself with a WIDEBAND O2 sensor, so rather than just leaning it till it knocks i can actually tune for a specific ratio.



others here have used the safc2 with a 7AFE, but they were on their way to go turbo and just messing around, i dont think any were using widebands to tune by. you really cant tune without reliable O2 sensor feedback.

so you're using a piggback? i dont think its worth it for the 7afe IMHO! save up all the trouble and the $$$ for engine swap or F/I!

uhm....if i went FI, what am i supposed to use to control the engines tune if i dont use a piggy back? am i supposed to do a trans swap and get a full standalone like an EMS or a Megasquirt?
