Technical ecu question

Recommended Posts

I was just wondering who is using the AEM fic ecu on their supra.

 

I have got hold of one and would like a wiring diagram as i have a universal harness and i cant seem to find one online. Any help much appreciated and if there is a standard mode it can be put into whilst im pootling around as na that would be good too.

 

cheers in advance

Are you TT or N/AT? sorry but I will warn you that the FIC is not capable of advancing the ignition timing, you can only achieve advance by globally advancing the std ignition timing and then retarding all other cells, not ideal IMO as if anything goes wrong....... you may be OK with N/AT if you just want to pull timing.

I was looking at one of these for another car but when I found this out I changed my mind.

Its for na-t :)

 

From what i read it has full control of fuel and ignition timing that was the point of it?

As I said unless they have revamped them, they are not able to advance the timing.

 

Quote from AEM about the fic "TIMING RETARD CONTROL

 

The F/IC can retard timing from the factory system based on engine RPM and load inputs. This is achieved by intercepting and delaying the outputs from the cam and crank position sensors to the engine- with no adverse effect on applications equipped with variable cam timing."

Fair enough, but for na/t all i will want to do is slow things back down anyway wont i?

Yes for N/AT you will probably get away with just retard.

 

Spot on thanks.

 

Yer as far as I understood it strapping a turbo would speed things up, and this ecu gives me the ability to slow everything back down. Sure that is the simplest way of explaining it but still trying to get my head around it all.

Mine's an AEM 30-1100 V1 standalone not a Fix It Cheap. ;)

 

Already new yours was a all singing all dancing one, read through your build a million times. But you would never have gotten away with anything less! :)

 

Do you happen to know where i may find a wiring diagram, the model i have is the 30-1910.

Googled. :D

 

I swear you dont google these things. You already have a downloaded and compiled history of everything technical ever needed!!

 

So its just a the basic task of now getting the wiring diagram from the toyota tech manual and matching what the aem manual says to do to the wires going to my ecu. Simples.....

scott the FIC does have some trouble with the cam and crank wiring of the N/A it also does not like the votex maf sensors, i think i rember that you have to get the singles from the dizzy cap or something like that to be able to even affect timing ,

please read the link to the fic forum,

if i was you i would go with a know and proven ecu that works well, i did think club N/A-T had masses of info on this but im not sure if the sites still around?

I thought from reading the post on the fic page that the timing was simple to adjust as there are 6 pinouts for the dizzy or am i wrong. Im aware of this ecu being used on na-t builds from googling which ecu's have been used and thor have done 2 builds i believe with the fic, one of which i think is a club member on here.

 

I was under the impression this aem unit was a good one to go for for the type of low power build i am attempting.
