so put down my power goals ?

gen 2 fc ?

im just saying hes putting down that much power with a full internal rebuild(stock spec parts though) FMIC, fuel cut defeater, and other than that a pretty much stock engine management. no tuning.

VEMS which member are using them?

this is GREAT info guys! i have a greddy E-manage blue (will be selling soon) i have decided to go with the AEM FIC because i heard it was better. i always hear that piggy backs fight with the 3sgte, so thanks smaay for clearing that up!

To the OP, as far as standalones, i wouldnt bother unless you KNOW youre going to go bigger turbo, more motor etc. if you only want 270-300 you should be okay with that piggyback from what ive learned

just fixed my issue temporarily - retarded timing a bit (now less than 10), but fuel economy should be worse, also power is lost a bit.. still considering AFC to add fuel

the FIC is still a piggy back.

your saying that you lost power for a AFC?
which one where you using ? and did you retarded your-timing ?

are you following? my engine is detonating. i dont have AFC, but im considering buying it to ADD fuel not remove. because i have higher compression, so i need to enrich the mixture to keep it safe and enjoy the higher compression at the same time. or use octane booster..
currently i retarded timing to play safe..

Quoted for justice.
Seriously man if you are just trying to get yourself a better safegaurd against det, there are a million other ways to go about it. Ive covered it once, but what really matters is what your current and future goals are...if you are looking at your stock engine and only want to get the most out of it in its mostly stock form (internals, ecu) then an aftermarket FPR/fuel pump combo would be good to go. I mean you could also add in a wideband, water injection, J&S safegaurd and have an engine on the stock managment system that could handle anything you throw at it.

But if you are aiming high NOW or a bit down the road, then keep your timing retarded, get some sort of aftermarket engine managment and wideband and throw that sucker on a dyno and go from there...but even then you would be faced with improving your fueling system along the same way as the above choices.

Thanks man, i really appreciate your reply
" Ive covered it once" - do you have some kind of article? Id like to read, you seem to be good to sum things up when its needed
of course ECU is the best thing on earth, and still i would need fuel upgrades that would also do some good even without the ECU.
My goals are not to go over 280horses at the flywheel. if i ever come to cross that stage, its years from now, when i will have enough funds for good ecu, wideband, turbo, chassis improvements etc and only then i would think it over many times. engine safety first, power later. i learned the hard way. twice.
Are you sure a bigger pump than gen3 is required? isnt it enough to support a slight afc correction? of course i run stock boost and dont plan to ever touch it. i dont like aftermarket parts i love the 3gen 3sgte, its so many light years ahead of gen2 (compared stock) those stock parts are very well designed for 20+ years the only thing i miss from gen2 is TVIS tuning..
and fuel pump change on mr2 is a b**ch, unlike nissans where its almost easier than changing battery

i am planning on turbocharging my 7afe, and am stuck with the decision on what to do about engine management. Is it completely necessary to control ignition timing even when running low boost, like 6psi? Will the ecu advance the timing too much and cause detonation even at that boost level? Those who have gone the 7afte route, what have you guys done about controlling ignition timing and fuel? Im thinking about going with the aem fic and was looking for some feedback from people who have used it. Let me know what you guys think!

steff (hurley97) has the FIC on her car, and i think smaay uses it, or was using it on his as well.

After doing a lot of reading , I would say the only problem with the AEM is the crank and Cam sensors wiring , it seem that wiring CAN be done but will not allow you to tune timing , So that bring me to the Apexi-Neo it would seem that both system give the same tuning option

Apexi-Neo looking to be easer to Install , both are in the same price range

Is it possible to get 300-310hp just by tunning AEM FIC correctly?
Engine internal is absolute stock.

^--- at the engine yes, at the wheels difficult.

I'm in a similar situation to what I've read, I have an ST205 with a fully built motor (stock cammed), has 86.5 overbore je pistons (+20cc ish), head and block surfaces planed(extra compression), eagle rods, acl bearings, arp bolts, etc running garrett gt2860rs turbo (similar output to ct20b, but with crazy spoolup), tial 44mm external gate.

running factory ecu with no form of tuning

here are my current precautions..
- spark plugs 1 step colder (was heat grade 6, now heat grade 7) - NGK BKR7EIX
- ignition timing set at 8 deg
- cooling upgrades: water header tank, alloy radiator, w2a IC runs redline waterwetter
- oil breather tank with PCV/Intake deletion (octane robbing oil vapour goes to atmo)
- only use highest available octane 98 RON
- currently using the blue spring (6psi)

planned...
- walbro pump and adj. fuel reg.
- afc neo
- wideband gauge kit
