Default Requirements to go stand alone

Good morning guys,

I have been having some general conversations with some local friends about going stand alone. I called AEM and Halltech to see if they had any offerings for a 2015 STI and they told me no.

I was under the impression that any engine could be connected to a standalone ecu.. when I inquired further, the person on the phone said something about the crank and pattern but I did not catch on. He said there were several "common" crank patterns that I should be able to just switch out on the engine?

Can someone explain what they were trying to convey ?

if you are looking for a pnp I dont think there is anything. you can always wire it in, but yeah the only thing is there are little problems that you can run into with sensors not working very well with the ecu. so with that said, the best way is to go to a shop like element and have them install and tune the car.

The biggest issue with all the 2008+ is that they are CAN based. A link ECU would have no issue controlling your engine... most standalone ECUs could... but speed source is ABS via CAN... cluster is CAN I think.. etc etc.

doesn't haltech do CAN? would probably need custom coding to get things to talk? i think they were talking about the crank position tooth pattern. im pretty sure all new-ish(newer than about 2000?) have the same crank position pattern on the timing pulley. a standalone will run any engine. its just a matter of adapting all the harnesses so everything is wired together right. and you might loose some OEM functions. that is one reason its nice to use open source reflash on the OEM ecu. you can retain alot of the stock functionality and add on more.
