hi
i bought a apexi power fc of some1 for my95 wrx which is getting mapped next month... however i know nothing of how to test the ecu so i simply removed mine and plugged the apexi in and reconnected battery turned key and its just winding over with no attempt to start

does this ecu need to be programmed before it will even work in another car or even worse does it not work at all


any help would be greatly appreciated

dude dont run the power fc with it being mapped a stcik with you old ecu until you see your mapoper and these quetsion are better answered by your mapper

 

im not gonna run the car until its mapped just to make sure the ecu is working i dont wanna wait to remapp day then realise it doesnt work thats all m8

 

Thought these were plug and play would of thought your motor would of fired up try getting in touch with a mapper mite be some way of reseting it!

 

Chances are the PFC has a previous owner's map on which could be for a big turbo set-up etc. That said, I wouldn't have thought the fuelling for cranking would be that way out, so that it couldn't start your car!

If you have the Commander, you can intialize the ECU back to factory-supplied base map - this may be enough to be able to return the fueling (if that's its issue?) back to something more suitable, so as to be able to start the car???

 

Have you manged to get it going yet like mate!

 

As said above, don't attempt to start it on the map from the previous car it was fitted to.

If you still have standard MAF and fuel injectors fitted to your car, then you can reset the Power FC to it's original basemap, and then it should start and tickover fine.

On the Hand Commander press the 'Prev' button until you get the MONITOR/SETTING/ETC menu.

Go into the ETC menu

Goto the Initialise ECU Option and reset the ecu

Turn the ignition Off then back on again.

The car should now fire up.

 

Craig, get hold of a hand commander and it can be reverted to base map in seconds

 

thanks for all the replys folks, im gonna need to get a hand commander and reset to base map hopefully get a result then and be looking forward to my map day

 

i ghot too bro, and connected it up and before starting the engine you have to intalize it to factory, as long as it is the correct ecu for your car the sticker on the side should say so as mine says gc8, any way i did the initalize then started it up tick over for 10 mins so it can stabalize then turn the heaters on for another 10 then the a/c for another 10, then went for a drive of boost and it drive as if i had the factory z4 in, then on boost it is spot on, just saving my pennies now for a tune up as i have the avc-r also...............
