Sorry newbie to this...

I keep searching but all links I find dont work anymore...

I need a link to Apexi PFC install manual for 1994 fd3s.

I found the commander one.

Also read the reset and learn idle info.

Install manual?
Why do I need to cut four wires?
Which wires?
Does ecu need to be grounded like stock one?

Anything I missed?

sorry again for repeat/newbie question

Thanks!

I have read the link you posted...still have these ?s

all links i find for install manual -doesnt work...i want to download one...got a link?

It says wires are for EGR/AWS/RPM warmup/split air bypas...its a us model...why do i need to remove these?

does not say if need to be grounded or how...

philiwily

The US cars had more emission control like EGR than the JDM cars, The PFC was designed without those US emission parts.
If you dont have any luck with links PM me your email and I will send them to you.
Mine is not earthed.

could i leave the wires since the pfc isnt designed for them? Or does it send incorrect signals? currently my airpump is disconnect but not removed until i get single turbo parts...

I have never seen a PFC installation manual. My PFC came with the Commander and the included manual was for the commander and in Japanese. On this site is the manual for the Commander in English - use the search functions. If I remember nopistons.com also has it posted.

If you do not disconnect the wires the PFC will not function properly. All I did was remove the pins from the connector and shrink tube them. Get a pin removal tool from RadioShack. That way they can be put back should someone want to restore to original.

philiwily emailed it to me but it doesnt say to ground...

No ground required for the PFC chassis. The grounding is taken care of through connector #4. Pins 4A, 4B, and 4C are all grounds for various functions including the PFC chassis ground.

ok installed and boost was allowed to 15psi and knock was maxed out above 2k or 50mph...any ideas...i reinstalled the stock one just in case

gnictry

iTrader: (10)

knock on the bar is one line or so at idle
then accell softly shifting around 2500 3000 it around half way
but hard accell or cruise or accell in 5th it full bar
Not sure value of bar or if this is important...
i got new ngk wires and plugs and most things are stock besides sig...

philiwily

Are you saying you set the boost to 15psi? Are you still on twins?
The base map on the PFC is better than stock if you have a few mods but you should take it easy until you get it tuned.
If your going to do it yourself you should do a lot of reading of previous threads on here.
Im not being cheeky, just don't want you blowing your engine.

nope not change settings for boost just reset and ran...not sure how hit 15 since its runs max 11 with stock ecu and manual boost controller

gnictry

iTrader: (10)

What should the boost settings be for base map on the pfc?
I am planing on removing the mbc and just using the pfc...i dont want more then 11-12psimax.

any opinions on the knock?

should i ignore this and use the pfc or stay stock ecu unil i can send pfc to get tuned?

gnictry

iTrader: (10)

anyone?
I removed my mbc...think I have built in restrictor instead of inline ...will that effect pfc boost controll?
should i run stock ecu and get pfc tuned by mail...(my rear turbo shot so cant tune car)?

or just throu in pfc....?

gnictry

iTrader: (10)

any suggestions? i call kdr but no answer...i would like to mail it to closest tuner i can.....if i have to tune...

Knock?
Tune or throu in?
Boost?-built in pill...?

gnictry

iTrader: (10)

anyone?

gnictry

iTrader: (10)

i installed pfc...
knock is average 150-160
injectors max 73% runs richer...
can hear/feels second turbo open and injectors on when light accel, egt are lower too.
turned boost down but left base duty alone...is that ok? hits 11psi but normally 10.

gnictry

iTrader: (10)

do i need to make any adjustments to the base tune besides turning down boost?

ttmott

The knock count is off the chart! Are you sure that is correct?
Unless you have a Datalogit and laptop you cannot change the base map. All you can do with the Commander is offset the base map by percentages entered in the Fuel Correction Map; and that's limited.
You need to get the car to someone that can baseline it before something gets torn up; looks like you are trying to do things with the commander but don't have enough data to make the right decisions / adjustments.

Is there someone in your area that specializes in the rotaries that can take a look at it?

gnictry

iTrader: (10)

not close the pfc would need to be mailed or me drive it north 5-8 hrs...which i dont have money to do or for a good tune...

yep knock was 164 other night.

engine cold-first start up and warming up



cruise knock 168 at 2600ish rpm



Knock once warm at idle

kdr said knock is irrevalant on the pfc bc it is too sensitive and picks up engine bay noise.
