I just installed my PFC today and am using the base mod map, when i first started the car it idled at like 2200 rpm for about the first 5 min. Then it begain bumping from like 1000 to 1500 up and down. Then it finally levels out at around 1000 but as soon as you touch the gas or change the voltage load it starts bumping up and down again. I cant figure why it would do this or what to do about it. Im not getting any exhaust light warnings or anything. Sorry for the long winded post its just i wanted to explain the whole process I went through.

Thanx
Jeremy

 

stock ports...right? base map?

Tim

 

Yeah i have stock ports, and base mod map. I checked it cell for cell with the one thats in the sticky, its brand new PFC and I didnt change anything. Also in the sensor utilities what are the ones that should be on while at idle? I have 4 on the rest off. Donno if this is anything to check? Also my check engine light would come on now and then with the pettit ecu I had so maybe I should just put the pettit back in and go get it checked out somewhere, whatcha think? I didnt have any secondary boost with the pettit either. I was hoping the pfc whould help this problem, oh well.

Have you tried adjusting the air bleed screw by turning it in(closing it)? This problem has been discussed so many times, did you do a search?

If you knew you car well, you would have tried manually adjusting the idle yourself!

 

It idles fine with the pettit so I didnt see that this would be an issue.

 

The PFC has a finer and more efficient idle control.

It is a different ECU.

 

Want to meet up over at Damie's house and check it out? We are working on his turbos again so drop me or him a line and bring the car over.

Tim

 

When? This weekend or during the week?

 

I had the same problem........
until I finally removed the wires that I was supposed to remove as instructed in the manual.

 

I did remove the 4 wires that the book states.

 

How long have you let the engine stay on? Have you driven it?

The PFC goes through a learning mode that lets itself adjust to your engine. When I first plugged it in, the idle was all over the place but I drove it around a bit and it finally calmed down. I still had that crazy warm start up idle, though, and that finally went away after I removed the wires.

 

I let it sit for about 15-20 min running and didnt try to drive it. Maybe I should have let it run longer? Donno or ill just try to drive it tomorrow or something.

Read the manual.

You are supposed to let the PFC learn the idle for 15 minutes with no load, 15 more minutes with the rear defroster on, and then 15 more minutes with the a/c on.

Yep, I thought 45 minutes of idling was excessive so I let it sit about 2 minutes on each setting (seemed stable). Well, guess what? The idle bounced all over the place when I was driving around.

The next day, I reset the PFC, did the proper learning procedure, and haven't had a problem since.

Lesson learned. Read the manual.

 

How can I reset the unit? Is it in the commander settings or do I have to do a regular reset like with every other ecu.

Laterz

 

No offense, but you need to sit down and READ THE MANUAL. All of your questions are answered there. If you don't have it, you can download it from this forum or Steve Ciriani's site (or other places). It might be labeled as instructions for the Commander.

And yes the reset is done via the Commander. It's in the manual.

 

Sorry but I am at work when I am on here and I dont have alot of time to do this, I was just lookin for some quick answers without alot of hastle.

 

PureMdMa,

this forum is really hard on newbies and people in general. I think the problem is that too many "know it alls". This is what i do...read the stuff and ask when it is totally necessary. Tip...read what you got...search for your question, not just one time but few times with different combo in word. Some thread come up but others don't, so, yeah. Then if you still have questions...take your chances and start a thread. I hate short threads or replies..

in this case...

it's actually both parties fault that makes the threads ending bad. Rynberg has a point with reading the manual. But everybody wants quick answers. So i think people should help you out little more than read the manual or something in those context. And you should read the manual even through it looks long, but this will help you not just the learing mode but others as well.

Now for your problem....do the three 15min setup...you should be good to go.

Actually, I did tell him how to do everything but reset the PFC, which is very easy and is one of the main submenu headings. To me, installing an aftermarket computer that could instantly blow my engine without fully reading the manual is not a smart move. I read the manual about 3 times and did a lot of reading here before I actually installed the thing.

As far as the forum being hard on newbies, it's because many newbies are just lazy. I read this forum for weeks before posting a single thing. Even after being a member for 2 years, I have hardly started any new questions threads. Between other websites and the search function here, you can find an answer to just about everything you want to know.

 

I really wouldnt say im a newbie just new to the pfc. I usually do a search on everything and dont do many post either as you can see by my post count for how long ive been a member. I just had one question and didnt want to mess with time consuming searching that I didnt have the time for at the time. Anyhow thanx for the answers. everyone can go ahead and take a seat.

Rynberg helped me with this problem. Yeah, I'm lazy...

Do the PFC idle "learning" routine...

Reset the PFC from the commmander, key on, key off(I can't remember if you have to repeat this step a few time...

~Then let the car idle for 15 minutes...
~Turn on the rear defrofster and let the car continue to idle for another 15 minutes
~And then turn on the parking lights and let it continue to idle for 15 more minutes...

This worked like a charm for me.

Thanks Rynberg.

 

I can't find my manual, and the one on the Apexi-usa site is for the civic, but on what page does it state the above mentioned idling procedure?

Tim

 

Tim, on page 10 of the manual on the Apexi site (Civic). I never had the manual for the PFC itself, not having bought a "USA" version. I have heard people say the FD PFC manual is essentially the same.

Although, the manual actually says 10 minutes, not 15. Oh well, it works with 15....

EDIT: When I say PFC manual, I am NOT referring to the PFC Commander manual....

 

thanks, I just wish I could find mine since I know I had one....maybe teh wife through it away

Tim

 

I tried the 45min idle thing but used the A/C for the last 15 not the parking lights, would this make a difference cause it never stopped bliping up and down and all over the place. Seems like it never stopped trying to learn cause something was wrong. Anyhow I put the pettit back in to get the error code it was putting out previously and its the EGR Sensor so ill check that and try to get the car without check engine light on before reinstalling the PFC.

Laterz

 

Finally found my manual and just for the record, it doesn't have anything about the idling for 15 mins, 15 mins with a/c, etc. Although it works for most, it's not in the manual...just thought I'd clarify.

Is the EGR hooked up correctly?

BTW, this is my 2000th post
