apexi power fc, evo 4

[HermaN]

yeah i totally agree with what you are saying, the standard ecu has features available that the PFC doesn't, but that doesn't IMO make it better. it may perhaps make the PFC look like a dinosaur compared to it, but i do a lot of mapping, standard and aftermarket, and i'd still rather use a PFC. works perfectly, easy to scale new injectors, easy to scale load (seconds) dead easy to map, live mapping etc. from my point of view its bang on.

Easier isn't always better tho. I also don't understand why anyone with an Evo 5-9 would go out of their way to spend money on something less capable than their OEM parts.

Ditching the OEM ECU for LinkG4, Vi-Pec, Autronic, MoTeC, GEMS, etc I can understand, but ditching the OEM ECU and spending money on a PowerFC is mad IMHO, it does not do the job of controlling the EFI system any better (or any worse),has less features, costs quite a lot brand new compared to the free OEM ECU and is god knows how old now.

I map OEM and aftermarket ECUs for various types of cars, not just the Evo, and unless the OEM ECU is not mappable then I don't see the point in a PowerFC, other better ECUs are 1 thing, but on all OEM mappable applications I have never seen an advantage, be it with Hondas, Nissans or Mitsubishis, PowerFC offers nothing over the OEM ECUs that make it worth it's price tag.

I'm not saying it's a bad ECU, I have mapped them and they work well, can't complain, do as they say on the tin, just why spend money when what came with your car is just as, if not more capable.

The only reason I can think of why you would want one is if you need a cheap way to run SD and don't want to pay for expensive aftermarket ECUs, but then that's only the D-Jetro that supports SD.

This obviously does not apply to the OP if he got his for a really good price like he said, because the stock 4 ECU was not mappable so they would have had to buy an ECU regardless.

hi everyone that has helped me so far, just a quick one,
i put my apexi power fc in today,
i had to cut the wire that u guys said, so thanks for that.....
the thing is my engine warning light has come on. is this normal? before it gets mapped,
(car is booked in for tomorrow)

More than likely it's looking for a boost control kit to be plugged in, not a problem, can be switched off in the software or on the hand commander

Herman, I understand what you are saying, and no I'd not recommend someone spending fortunes on a PFC, but the whole standard vs aftermarket ecu is pointless. Yes the standard ecu does it's job great and is good for a bit of tuning. What happens when you change to bigger injectors? You change the settings in the rom, then spend ages logging fuel trims until you get them just right and the ecu is happy with them. So do
I then charge the customer hours of my
Time because it was a pain? Course I can't, that's where the simple PFC excels IMO. I never said it's better or worse than standard ecu, the fact is the PFC is nicer to work with.

thanks, u have put my mind to rest

just to let u know i made 330.7 at a tad over 1.3 bar of boost,

and a big thanks to everyone who helped me with there input and advice,

Sounds good mate, how much power @ the wheels?

 

[richiebaby]

hi there will i be ok to wire a air fuel gauge to pin 76 i think it was,

also can i use pin 83 for a water temp or is it best to use the sender that came with the kit,

good result buddy :O)



.as for the pin's it really depends on the gauges you are using . always a good idea to use the sensors that are supplyed with the unit .

but its worth a try if the voltage range and resistance are the same for both sensors .

afr gauge to pin 76 should be ok :O)

good luck buddy

E5 and E6 ECU

you'd be better off sticking to the standard ecu over the apexi as it has more features and has the knock control

Will it also be the same (more features included and knock control) if using an E5 or E6 ECU?

yeah have a search for the ceddy rom for the 5 and 6 ecu and its features

Well, I actually live in Los Angeles and bought a half cut Evo 4 from Japan. Now after I have converted a legal Mirage FWD to AWD Evolution 4, the engine is experiencing fuel cut @ 4000 rpm. I installed two stock Evo 4 ECU with no luck. Some say that it might be the actualtor but I am not so sure what to do. Any advise is appreciated.

Thanks.
