is there any thing i need to know before i order a power fc?

[jrb92se]

ive got a 92 240 coupe with an s2 rb25det, i am going to get a pfc/commander. is there any thing that i need to know before i order it, do i need to get one that is programmed for this engine in this car ; or can i just order one for an rb25det ? i know i have to get it dyno tuned after i install it but is there anything i shoud tell them when i order it ? thanks for your help

[Carl H]

power fc is a power fc, just make sure its for the ecr33 rb25det as there is a diffrent one for the r34 rb25det...if you have a relatively stock setup in your car you proly wont need a dyno tune, as apex sets the maps up for mild mods.once you start changing things like injectors and maf you'll need a tune.

[jrb92se]

cool so basically i can just buy it then , thats great. it's not going to mess up the power windows or anything like that is it?

[Carl H]

why would it mess up the interiorbits...that stuff is on a completely diffrent harness.

[jrb92se]

im clueless about how the car is wired. but in the next couple weeks im also going to get an electronic boost controller i dont know if it will matter when i hook it up that the ecu is changed or not ive never had any expierience with this stuff so thanks for helping me out

[Carl H]

power fc can also be used as a boost controler with the proper kit...

[kouki-gymkhana]

Whoa, looks like you should do a tad bit more research before you spring for that Power FC!

i was going to get an safc2 but people on nico told me that it was just a band aid fix, i want to just go ahead and do it right the first time so im going to get the pfc. im not going to try and fine tune it myself or anything ill take it somewhere for that but carl says that it is plug n play out of the box so in stall should be easy. this thread is part of my reasearch .

Are all the PFCs for the R33 RB25's D-Jetro and run on Map? or do they still sell the Maf version. I'm thinking about ordering one as well and want to run Map, but not have to buy the conversion stuff later to do it.

[jrb92se]

i thought the djetro version was better am i wrong ?

[Carl H]

d-jetro = map basedl-jetro = maf basedthe std pfc is maf based, the only d-jetro pfc's are for the rb26 and the sr.map sensor is NOT better than a maf as it only measures pressure not airflow.

[jrb92se]

so all i need to know is pfc for a ecr33 rb25det? whats the best place to order it from

[Carl H]

i got mine from nengun.com, was about 650$ before shipping and ended up being a hair under 700$ shipped.

[jrb92se]

sweet thanks alot man your a big help for real

So is it worth converting to D-jetro from l-jetro on the RB25? If still running an l-jetro, would upgrading the MAF be recommended. I feel if I need to pretty much spend the money to upgrade MAF to reach higher horsepower using the l-jetro, I might as well spend the money to just convert to a Map sensor system. Is it pretty much just preference when it comes down to it?

[Carl H]

there is not d-jetro pfc for the rb25.i suppose its a preference thing but with a map sensor once it reaches full boost there is no more load increase so you are limited in tuning.

[Imissmyturbo]

Check how much you can get an extra commander for. Mine was stolen the other day and I need one.

even if there was a d-jetro for rb25, my understanding is that you can't just "convert". the d-jetro box is completely different than the l-jetro. you need to get a different pfc altogether.

I haven't read into them a whole lot, from what I was told the PFC can run on both and I thought I've seen people talking about converting to D-jetro systems and buying the apexi map sensors. I may just end up getting a used Haltech E6K or something. All my buddies run those on their cars and seem to like them, and tuning isn't hard. Plus it runs on a PC, runs MAP, and I can sell my harness and make some money back.

[Carl H]

there is NO way to convert a std pfc to a d-jetro system it is a totaly diffrent powerfc.

[Sky80]

the only d-jetro pfc's are for the rb26 and the sr

there is not d-jetro pfc for the rb25

Wow how many times does he need to spell it out... i hope the third time was a charm

Yeah man, you're ****ing cool Why don't you make this board seem like it's more full of a$$ like yourself tool bag. I was just asking simple questions going on, apparently bad or misunderstood information, from people locally. This forum is supposed to be used for helping and sharing our experiances with the RB, correct? loser

Wow get mad about it! DO IT get mad... lol

[jrb92se]

all my threads seem to bring out the worst in people

[jrb92se]

sorry to bring back a dead thread but i have another few ques about this topic. ive been saving for an engine manament system for awhile now i was just gonna get a pfc but a few people have suggested the megasquirt instead and also aem ems. which is the best option and what are the downfalls if i where to buy one system instead of the other .......i did search before i posted and i didnt make a new pfc thread so mods help me out with some good technical info please !!! thanks.

Unless you have someone knowledgeable about the Megasquirt around you I wouldnt recommend it. From what I have seen around here its a good system if you have the knowledge to build it and maintain it yourself. It is a huge DIY system so if your comfortable with that go for it. Otherwise I would stick with AEM or PFC. I personally will be using the PFC after reading some of the cool things about it on here. The big thing I like about it is its plug and play. So theres a little info for ya anyway haha.

[Carl H]

megasqurt is good if you feel confident enough to dive in and build a new efi harness for the motor, you also have to build base maps for it...ask eh? on this forum for his thoughts on the aem...imho pfc is the way to go for most ppl...

[eh?]

AEM for 500whp+ and all out drag. The price difference gets narrower after you add up all the features.For a daily or "weekend cruising" it's not worth it.

[jrb92se]

so thats +3 for the pfc

[FriedEGs]

+ 1 for power fc

my buddy still uses his for his rb26 with more than 650Hp....

keep us updated.. that's next on my list of mods...
