Power FC or Lumpy ROM?

[Remix]

Help me make the ECU choice for my RB20DET. Positives and negatives for both.

Power FC or Lumpy ROM?

Thanks :)

[TJ]

power fc - direct plug in, easy to tune well
inbuilt knock warning
handcontroller provides useful info to you
many tuners available to tune
popular for a reason
removeable when car is sold so ppl cant tell uve flogged its ring off

negative
need to upgrade afm so more cost
initial cost is higher
it doesnt do rotational idle or antilag bro oh no!



rom - whether it be lumpy rom or biki rom (be fair to both)

cheaper
switchable maps with differing boost levels
can do some wonderful things with them now such as launch control and flat shifting
inital cost is lower

negative

some ppl say they dont work as well - less range of tuning
limits you to particular tuner (NOT THAT THERE IS ANYTHING WRONG WITH ANY OF THE TWO GUYS IN PERTH THAT DO ROMS) ie what happens if you move to another state - do you need to start again.


im sure thats more but thats a start linchoong

[Remix]

Thanks for that TJ, some good info there. I was not aware that the AFM had to be upgraded to use the PFC.

When you say 'switchable maps', how are the maps actually 'switched' by preference?

[doriae86]

id go pfc just based on the wealth of information fromt he hand controller

[B0BB0]

well your in the same boat with the afm for pfc or rom, coz u are only upgrading to get better flow, so it will have the same pros n cons of doing the upgrade be it pfc or rom.

emanage is ment to be pritty good to.

[TJ]

no one tunes emanage though bobbo so as good as it is its useless:

switchable maps - switch on the dash, flick it up for say the low boost map, down for the high boost map

[DemonAce]

My choice would be lumpyrom..

Apexi should stick to making guages and suspension.

[pnblight]

i think it comes down to your budget and have far you want to take the car.

Apexi pfc is the best management for a streetable car package i have ever seen ,i am running 529rwhp gtr that starts ,runs and drive like a std gtr until you leen on it, then it is simple breath taking (Yes lumpy tuned it).

If your got the budget pfc is the shit

[TJ]

pfc isnt that expensive anyway - can be had for 1k odd with hand controller.

[magic1]

you would be crazy to get a rom these days, (this is my opinion only do not shoot me or hunt me down)

[DCIEVE]

does the rom do temp correction?

[SimonR32]

i choose you power fc :)

[Starion_turbo]

Ive had a Biki Rom in the 180 and a Lumpy Rom in the R32. I am a firm believer in the Roms as they have never failed me. They also show a big increase on cars with bolt ons. I personally wouldnt hesitate going for a ROM again - While there is nothing wrong with PFC, it does cost a bit, it costs to tune it as well. The advantage over a ROM is the tuning available all over the place and even interstate.

Dont know what the law is like with aftermarket EMS over there - but over here if the EPA seen u with a PFC they would have a heart attack.

[doriae86]

new pfc is around 1k
when you goto sell the car u can removbe pfc and get most yourmoney back
with rom - cash gone!~

[zeroyon]

Dylan your loosing $100 on a rom .... I am not going to cry.

Thats the thing. IT IS $100 ish for the ROM. Its the tuning and install that brings them near the $500 - $800 mark.

No different to a PFC.

Personally being a big fan of roms I can say you cant go wrong with either. The rom is your budget option and works well. The PFC offers a little more at $900 more.

If you have the money get the PFC.

If budget is your game, the rom is the choice.

Simple

[TJ]

butters car is an awesome example of a rom that works and bloody well

[magic1]

however it is cheaper to retune a PFC than a rom.

[[RX2]]

id go the apexi, like stated b4 you can take it out if ur gonna sell the car & keep it for something else, & its handy to have a hand controller.

[razor]

One day I will get a Lumpy ROM for my Ceffy. One day....

*insert Lumpy-love comments here*

[zeroyon]

however it is cheaper to retune a PFC than a rom.


Not true, same rate per/hour and takes very little time to re-tune.


you can take it out if ur gonna sell the car & keep it for something else

You can do that with a rom as well. Both items are car specfic too. So its not like i can take the power fc from a 32 and use it on a rotor.

I am not one sided on this but there some to be some mis-truths about is all :)

[magic1]

its all healthy debate butters, but if i start to loss i stab you issit. with the rom can they be tuned in real time?

[doriae86]

pfc also deletes the need for yellow sticker magnet pillar gauges.
boost water temp etc all displayed on hand controller with peak hold and idhave to say with more accuracy than your avg gauge!

[Remix]

Have to agree there Dylan.

DEFI gauges anyone?

[[RX2]]

end of the day i think it would come down to ..1. personall preferance & 2. cash flow
(may be not always in that order tho)

[zeroyon]

rom can they be tuned in real time?

Of course they can ... requires equipment not all tuners are willing to buy though.

I do agree with you there dylan. The read outs are great. I personally think the Knock warning that the PFC has is the most awesome tool. Is it another $300 for a hand controller though ?

[Denver]

with the rom can they be tuned in real time?

With the gear lucas uses on the bikirom, yes it can be, im not sure if lumpy has got his tuning happening in real time as of yet..

but basically the bibkirom is emulated and tuned, same as a wolf/pfc/motec/other ecu then they burn the emulated image to the rom when the final tune is done..

cost factor the rom would probally come in cheaper than a pfc, even tho the you might get a pfc for 1k, you still need to tune it at $pr hour of tune and dyno time.. same as the rom..

depends on your application tho...

if you have minimal mods and want to just keep it stock looking rom it, if you want to tinker, get a pfc, if you have spent realy big cash, get a good ecu, read autronic or motec.. no point spending wads of cash on your car and then skimping on the ecu.. with the motec you can have full logging of everything, yes it costs money but *shrug* itd be cheaper than another rebuild..

horses for courses..

anyway, the new version of the bikirom is in development, software is comming along, and there starting on car testing shortly, so i imagine it should be ready to go out to the public some time soon..

should be ten times better than the old version and with more functions..

[DESAM8+PANIK]

Having had many lumpy 'love' roms I am a firm believer and the price is good too. If we start having epa issuses like over east rom is gonna ge the go .... I'll give you the hot tip.....

[Yoshee]

The main problem with pfc for rb20det is that you have to get the A.P Engineering model which is more expensive and doesnt come with hand controller as im aware, total cost over net being about $1650 plus tuning becomes bit expensive, im pretty sure you can get a rb25det pfc to work on rb20 if you use the rb25det engine harness but still the money you save on 25 pfc you spend on 25 harness.

If your after bang for buck go the lumpy rom (yes im am going to be biased here TJ) they work well.

[doriae86]

hey
i cna get rb20 pfcs to most people for around the 1k mark

[GhostFc3s]

You cant tune a rom yourself.

[Oggie]

You cant tune a rom yourself.

Lucas is working on that (BikiRom (http://www.bikirom.com/)). This new version sounds brilliant.

[zeroyon]

You cant tune a rom yourself.

again, yes you can. for less then the price of a hand controller you can get the equipment needed. True you need a PC to connect it to but hey, who doens't have one of those these days.

Question but, why would you want to though ......

[TJ]

i dont have a pc, i post on the net via telepathy.

[GhostFc3s]

No need for flash rom type equipment? If not so, Score.

Why would you want to? hmm leave that for another discussion perhaps.

[DemonAce]

whats the internet?
and whats this fandangled PC things your wobbling on about

[DemonAce]

Ooooh you should have put them In laymens terms
I like the call them
The Porn Machine
and The Porn Provider

[sLOW navara]

do your self a favour and just get a lumpy rom there is nothing wrong with them i run one and have no problems runs like a dream.
unless you want to go for a bit of wank factor with a hand controller you cant play with the controller as your driving down the freeway exceeding the speed limit can you so get the bloody rom and be done with it
