Can you do me a favor and try it on the 3.0l to see if it works acceptably?
just hook up the distributor outputs and see if it reads RPM and then try to put some retard into the table at idle and check with a timing light.
thanks

btw, even though its optical, it should respond like a hall effect.

Re: 3.0L AEM FIC Discussion
What about the MSD 7AL is it? It has a completely programmable spark curve and its built with boost in mind so it can retard timing too! :nod:
I might be getting a 93 AWD 3.0L van for the wife, so this now interests me, :eyebrows:
Re: 3.0L AEM FIC Discussion
FYI all the awd vans were 3.3/3.8. But a 3.0 swap is pretty straightforward, especially since you know your way around a transmission. You have to swap the AWD diff carrier into a 3.0 case but other than that i think it's bolt-in. Kreel did it so check out his thread (3.0 section i think).
Re: 3.0L AEM FIC Discussion
adam, quit posting on here and put the FIC on your 3.0L dynasty!!!! :)

Hmmmmmmm, ok, she told me it was a 3.0L, I asked her to describe it too. Crap, might have to rethink it, I don't want to be swapping transmissions, cases and engines, :(
Re: 3.0L AEM FIC Discussion
Then turbo the 3.3. :)
Brian, i am too lazy! Also im not touching the 3.0 dynasty right now because im DDing it while my insight is down. The last time i tried to do anything to this car when i needed it, i broke the computer. lol.
Re: 3.0L AEM FIC Discussion
cmon, its two wires. :)
sorry, its 4 wires... two for power and 2 intercepts to the dizzy. :)
Re: 3.0L AEM FIC Discussion
that and i would have to actually fix my laptop power jack so i can take it out there and read the stupid thing.. :p
Re: 3.0L AEM FIC Discussion
Well that will only take you two hours as long as you have 200 numbered containers to put the bits in as you strip it down :D
Re: 3.0L AEM FIC Discussion
back from the dead. nissan sr20det's running the aem f/ic or ems as well have sync problems with the cas disc. this is the same principle system we have on our 3l's. and in fact one of the common mitsubishi optical sensors is the exact one we have in our distributors. people are reporting frequent problems with sync'ing the hitachi made cas, but more success with the mitsubishi ones after altering how the aem software see's the signals (rising edge vs falling edge), but sync errors occur at higher rpms in many cases.
Re: 3.0L AEM FIC Discussion
Neon guys use the fic.. but they have crank sensors. Local guy likes his but i convinced him to go megasquirr.. but i think he changed his mind. Fic works well for him

So this wouldn't matter if you went with the AEM adapter on the distributor. Not that that needs to be necessary.
Re: 3.0L AEM FIC Discussion
if you use the aem cas disc then the factory ecm wont fire properly, it wont recognize the new optical pattern being sent to it. the aem cas disc is what you use with aem ems or possibly another standalone. from what i have been reading about the mitsubishi optical sensors, they provide the cam and crank sensor inputs for other cars.. ones with nissan sr20de or det's rb26det etc.. in these other apps, the outside high rate ring is used for can sensor input, and the inside low data rate is used for crank. then i would think that maybe our computers use the low and high data rate's in the same way.
what i cant tell for sure is if the aem would sync with our cas discs. one thing we have in our favor is our high rate rings have a void of 15 slots that would be recognized relatively easily, and our low rate is 6 evenly spaced evenly sized slots, unlike the rb26's with 6 evenly spaced from the start but unequal length slots.
the moral of the story is i am wondering if we could make the f/ic work on our 3l's giving someone the full benefit of a piggyback like this.
and with the rpm raised and speed limit removed from our neighbourhood tuner the key to a well controlled turbo setup without going standalone could happen.
im cheap.. and i want factory reliability from a factory computer
i suppose one could duplicate the cam and crank senor data rings with specially made rings adapted to the motor and send sensor input that replicates the stock setup to the sbecII through the use of magnetic sensors or hall effect sensors, as firing the aem f/ic that way seems to be pretty foolproof.
side note what is the minimum amount of time for a saturated high"z" injector to work. how large of a high z injector could one use scaled down and run at 43.5psi to give a correct idle mixture? 45lbs/hr? 60lbs/hr?
Re: 3.0L AEM FIC Discussion
Hah I forgot how the AEM distributor adapter attached. It does sound like someone needs to try it out before a lot of promotion is done.
I am also not sure if anyone is planning to be helpful with the rev limiter on the SBECII which is the majority of 3.0's out there. Limiter something that just screams to be raised.
Re: 3.0L AEM FIC Discussion
+ 1 on the limiter. mine was at 6400 or so during a race and i topped out 4th because i didnt feel the power loss from the diamante cams.. maybe i had most of my attention to the road but i hit the limiter instead of letting off when i felt the loss.
you guys with the regrinds can go even further than my petty 6800 limiter that i now have set for funzies.
so the only thing stopping people from using fic is the question of "will it work with our dizzy" ?
what about the apexi safc? do they have timing control. that would be another option. might be using one for my tach.. LOL, one expensive tacho.
Re: 3.0L AEM FIC Discussion
yep, the only thing stopping me is will it work with our dizzy, it'll be hard to justify buying it without being able to control timing. (could just go with my free emanage blue and a msd 6al-btm for cheap'ish from a friend, for timing retard in boost) but the aem would offer some very nice tunability if it would work.
for the record, shelgame can raise the rpm limit on sbecII's, he's currently doing it for another member with a v6, and ive pm'd him lots about what he can do for the sbecII's for v6's. im told rpm limit can be raised and also speed limiter.
Re: 3.0L AEM FIC Discussion
I know he tried it but last i knew he couldnt get the car to start on a socketed sbecII
Re: 3.0L AEM FIC Discussion
Shel-game has my ecu right now. He said it would be no problem to up the stock limiters. I sure hope my car starts once i get it back... This is for a 94 3.0 auto ecu car now has a swapped 5 speed though. Hopefully he doesn't mind but It cost about $140 with shipping both ways for those interested.
Re: 3.0L AEM FIC Discussion
The stock 3.0 dizzy operated just like an NPN hall-effect sensor. outputs go to ground whenever there is hole in the slotted disk under the sensor.
FYI, the low data info can be replicated with a simple 3 toothed wheel on the crank and and NPN hall-effect sensor.
Can the FIC take in a custom crank sensor signal (like a 36-1 wheel) and then output a stock style signal (3 pulses per crank revolution) to the SBEC?
Re: 3.0L AEM FIC Discussion
is it the high rate wheel or the low rate wheel or both that doesnt work with AEM products?
