ca18det/Power FC

Post by **bentvalves** » Tue Feb 20, 2007 6:33 pm

Anyone hear have experience with the power FC on a ca18det? I would like to get rid of my AICV and cold start solenoid (under throttle body?) and If I knew where the hot start solenoid was located, Id like to look into removing that as well.

I spoke to a fella in Austrailia that has a built ca18det running Autronic SMC engine managment. In any event, hes deleted all of the valves and solenoids, and has no problem with idle and cold start and that jazz.

Id like to get rid of all of that garbage as well, but because the power fc plugs into existing hardware and runs off existing sensors etc, im curious If I will have problems getting the car to behave and idle properly, with just the PFC alone? Im not talking about using the screw to set the throttle slightly open either, I mean the car idling on its own via the ECU.

Also, curious if PFC is able to tuned for fuel economy, or does it not have fine enough control over the injectors to allow for that? I spoke to a tuner about my girlfriends EVO...not the greatest fuel mileage. He said with his Autronic in his EVO (400whp), he was getting something like 32 mpg highway, but only because his SM4 allowed for "injector phasing" or something or other.

Anyone seeing 28mpg with their PFC ca18det's?

If anyone using PFC/tuning PFC could shed some light on this, Id appreciated it.

sorry for the rant.

You'll need the idle stuff for the PFC. I had one briefly and part of the initial setup was "teaching" the computer how to control the idle.

The problem I had with it (and the reason I got rid of it) was that tuning with the hand held is next to impossible. You can only see a small part of the map at any given time.

It's great in it's stock form as it has a huge improvement in power over the stock ECU, but if you're doing anything more than changing MAFS, and injectors, you've got to have the FC-Datalogit

Ive got a PFC i just picked up for my CA, but do to the 2 feet of snow my car wont be seeing any drive time for a few monthes..

Yea im looking into fc datalogit as we speak, but I may have a lead on the PRO software that the dealers use. Pretty sure Power Excel has a few features that datalogit does not.

But yea, If that falls through, Ill be ordering FC datalogit from Rotary Perfromance In Tx.

Ca20Silvia......whats currently running your setup right now?

SR ecu with the conversion harness...

Im not sure who tuned it but its tuned for 1.2 bar...

PS i added u to my MSN KS13

Do you speak of starting car and letting idle for 10 mins, then turning on the AC, radio, rear defroster, letting idle for 10 more minutes, shutting off?

Cuase Im pretty sure If I let the PFC self learn without those engine bay cluttering eyesores, then the only problem I might see would be with hot start.

Correct me if I am wrong but does'nt your SDS have the exact same limitation?

why didnt anybody point me in this direction? Rx7 owners swear by PFC, should be able to get some good info here.

Because this is a Nissan forum

You don't have an rotary.

Not to sound like a d!ck, but it just seems to be a dumb question "why didn't you tell me to look on an rx7 forum for tuning my Nissan pfc"

not to mention majority of the RX-7 community arent the sharpest tools in the shed.

Post by **bentvalves** » Thu Feb 22, 2007 10:45 am

haha is that right?

PFC is PFC, same method of accessing menues and files and data bla bla bla......

Post by **The_Chosen_One** » Thu Feb 22, 2007 10:53 am

you dont have a rotary, so tuning is different as the rotary has 2 power strokes, as well as bunch of other crap, thus why no one says go over to RX7 forums to learn about stuff.

Post by **bentvalves** » Thu Feb 22, 2007 12:20 pm

did you read what I wrote? Same way of accesing menus, files, logs etc etc.....

Apexi USA website has usermanuals for PFC and commander, and they are for the 13b and 13b only. Much valuable information to be had still........PFC is PFC.........lets not get to technical here.

If you have nothing usefull to say "not to sound like a d!ck" then keep it to yourself and stop wasting bandwith.

I have a CA18det with custom plenum and APEXI PFC with no idle control solenoids etc at all. I had to just reset the throddle for idle and it starts fine, drives great with no problems on std tune at this stage. The only side effect is the idle will vary a little hot to cold (no big deal) hardly notice it, and i guess when the a/c is hooked back up might be a slight pain pulling idle down.But yes it can be done no problem and no major dramas

wow, an answer that pertained to my question, you guys taking notes?

Adjust idle with throttle plate mechanically your saying?

Greg

thanks pete.

p.s. what else you got for mods?

Post by **pnblight** » Thu Feb 22, 2007 12:28 pm

thats not true i have tuned a number of cars with the hand controller NOT hard at all just a little slowthe datalogger is the **** tho as i run one on my GTR R33 PFC simple awesome

I'm not saying that it can't be done w/out the datalogit software, just much harder. As I said before, I tried it, and yes, it's doable, but not very user friendly.

TMS: SDS doesn't use a 2D or 3D map like you would normally see. It's really not hard to tune with at all. Plus it has the ability to switch back and forth from the gauge mode, to whatever MAP or RPM point your at with the push of a button, PLUS, it logs your AFR's at each RPM point. The fuel values in the MAP portion of the map don't really need much tuning, except for the cruising and idle vacuum values and those can easily be tuned while driving the car.
