Rather than cut the wires, use a very small pair of needle-nose pliers and carefully bend the pins on the PFC back and forth until they break off. Be sure to bend and break the CORRECT pins.

 

While I certainly say that clipping (or bending or whatever) the pins on the PFC itself is one way to do it, the commonly held theories on why NOT to do that is that 1) if you screw it up, you need to buy a new PFC, and 2) wires can be spliced back in the event that something like that is necessary. I've re-spliced, and while it's a pain, I found that the Molex plug suggestion that I put forth earlier is actually a good way to avoid having to do that, and at the same time helps prevent any mistakes that could be costly.

To each his own, of course.

 

hay wazzz-up? how much is the pfc?

 

the four wires that are disconected belong to: egr switch(16 pin, blue/green), aws valve(26 pin, brown/yellow), egr valve(26 pin, blue/yellow), split air bypass valve(26 pin, black/red)

 

My PFC and commander are coming in the mail today. I'm debating on installing it or not. I'm quite confused

 

You should only be concerned with the wires that should not be connected. The A/C fix is not really necessary. If you have problems with your A/C not working, you need to remove your fan switch and clean the contacts on the dial.

 

I'm in Europe and have a bone stock FD with HKS filter.

HKS downpipe in the pieline (waiting for the PFC to come in->fear of boost issues)
and catback as a next mod.
I've been told clipping wires is not necessary for Euro cars.

Remark: My A/c is working, though not filled, nor using it.

Should I just clip the wires, put connectors on, replug and unpleg them as mods are coming on?

thx

 

anyone know if 95-98 pfc will work in a 93

 

I just talked to rx7store and they said that the only that happens if you don't disconnect the wires is that the check engine light comes on and stays on. That's it.

 

No, but you might be able to screw someone on Ebay into buying it from you if you just lie a little bit...

That's what GravyTrain15 did to me...

 

Wow, that's f*cked up. Sorry to hear that.

 

so just to be clear because i get confused, do u NEED the commander because everywhere seems to sell em together, yet some people make it sound like its just an easier way to do it...and it seems u do because my next question is, is the commander the only way to program it? like if you want to use a map someone made for example u have to copy it yourself onto your commander, it doesnt like hook to a computer or anything?
sorry if this sounds dumb im just trying to learn how this thing works so i can be sure i would be able to use the damn thing. thanks

 

ok nvm guys...i see what that datalogit thing is. yeah i think i got all my questions answereed for now but thanks to those who WOULD have answered

 

this entire sticky should be junked and a new one generated with UPDATED information....what good is 3 year old date with a bunch of dead links??

mods, can you help please?

 

What do you suggest? At this point I can unsticky It...

 

Okay, I'll unsticky this thread than seeing how no suggestions are being made.

 

I think he meant some of the links are no longer good.

 

I would suggest editing the thread so any superfluous/out of date information is eliminated

thanks!
