a mates JDM DC2R with power FC - tuned

[ievaq8]

if this is in the wrong section please move.

Im posting on behalf of a mate and thought you guys may be interested in having a look at another car from Melbourne Australia

We where at a certain workshop (i wish to keep undisclosed so i dont start trouble here) all day on saturday RE-TUNING his car, thanks to another workshop (will not name) who did nothing for him but take his money..........

Regardless, it was a long day but the results speak for themselves, and Milan is finally satisfied with his JDM DC2R................for now.......hehehehe

Jdm dc2r with following mods:

Stock jdm 4-1 headers, HKS cat back (not sure of cat), custom CAI with K&N pod filter, crower stage 2 cams with crower valve springs & retainers, apexi power FC, im pretty sure that’s it………..

video of his final tune.....................car made a healthy 135kw @ the wheels on back to back runs once finally tuned....................(sorri for the video quality, its my photo camera..........)

some pics of the car itself



Enjoy

Hot ITR dude, ur mate should be pleased with that. pity about dodgy workshops, they should lose their ability to operate.

Noice..Reminds me of my old car, is that a carbon bootlid, or just painted black?

[MMJA]

Very nice ITR! Love that carbon bootlid look.

x2.. i want!!

I have pretty much exactly the same setup as your friend. But mine is just a B18c Block with standard p72 rods and p73 pistons, Crower stage two cams, Mine made 137.5 WKW on the dyno thanks to Sam for his awesome tune. Good to see another similar setup with pretty much the same power.

thankx mate, my mate is over the moon with the cars power and drivability now, the only shame is that he got ripped by the other workshop................ohh well, everyone wishes they could tune hondas...........

thats mad.................what ecu are u using...............i bet that if my mate had some decent headers and used a hondata ecu, he would have made closer to if not 140kw.................ohh well................its next on the list...........hehehe

just what i thought lol

[Loudsoundz]

My ECU is a socketed and chipped standard OBD1 Honda computer. I still need a CAI, Larger TB and maybe decent intake manifold. Some cam gears should squeeze some more power out of it with cam gears. Mine made improvements all over the range with retarding both cams a couple of degrees.

nice..........my mate like i said, needs headers and some cam gears.......and a better ecu........apexi power fc is shit for a na honda.......anyways.......

my mates jdm integra above........the more ignition timing we gave it the more power it made............and it didnt ping not one little bit.........

[Coupe-R]

HAHA, don't let Genkie read that. Actually he has got really good gains out of them. I've never used one, but they would take longer to setup and tune than a hondata or chip tune I assume (not a factory honda ecu so maybe need more tuning to get it running just right)

Honestly if it's tuned right there will be ZERO gains from going hondata or factory chipped ECU. All the motor wants is fuel and ignition timing to be just right, can't change that with another ecu. (as long as the ecu is fast enough it should be sweet)
Of course there is other little things like individual cylinder trims (if one cylinder is slightly out) and ignition dwell times that other ecu's can do (no one messes with em on honda really)

I tuned loudsounz car so very similar numbers to your mates car.

[ievaq8]

from personal experience and watching tuning...............
my tuner tuned my boosted dc2r with hondata s300 and the difference with the power fc i saw/found, was that you cant tune which RPM you want, u load the car up in monitor mode, and then tune the column and row ur in, and to get to the next row and column, it was a significant jump................not like hondata u can tune every 50rpm if you wanted to be anal................the power fc seemed to be almost 1500rpm............

just my observation and understanding.................but yeh, the car still made good power and gains............

[Coupe-R]

Correct about the hondata.
Can't comment on the power FC, but doesn't sound right to me.
Heck even a VAFC2 can do every 200-500rpm can't it?

[ievaq8]

i only commenting on what i know, and what i have seen with my own eyes..............

[Hayce]

Give your decimal key a break!

And yeah that doesn't sound right re: pfc.

[ievaq8]

..............i like my decimal key..........hehehe

sorri, i made mistake Power fc tunes in 500rpm range, but for part throttle driving you can tune rpm range, its load range, sounds weird but I cant explain it any better lol

[Coupe-R]

hehe sounds like this needs some clarifying.

I think i know what you are trying to say and it sounds like a microtech computer from aussie.
You have to tune each load point in a separate table on the micro tech. Takes longer and generally old school way of doing things.

Here is what I found off a aussie site called autospeed I often read
"However, the most major difficulty that we found was in working out where we were in the fuel and ignition charts - there is no indication (eg by highlighting the correct digits) of which data the ECU is accessing at any one load. Instead, there are load and rpm axes with arbitrary numbers - not actual rpm and manifold vacuum/boost, for example. This means that until some relationship between these axes and the actual load/rpm characteristics of the engine is gained, changes are a little hit-and-miss. "

Doesn't sound friendly

"If an ignition timing correction chart had been available, this could have been revised to retard the timing a little more with increased intake air temps - but as mentioned previously, no such chart is accessible."

THIS IS BAD, no wonder why I hear Genkei talking about the cars knocking in the heat of summer at the strip.

From reading the short write up on Apexi Power FC I have come to the conclusion that chipping the factory nissan ECU, has FAR MORE powerful features.
Likewise with chipping a honda ecu. you NEED Intake air temp ignition and enrichment correction!!!
Not to mention the price differences!

[Hayce]

LOL at it again eh...

[Coupe-R]

I haven't used one, but just reading that write up I was put off from it not having the features i often use.

Wondering why everyone raves about em. But I think its cause they plug straight in and have factory tuned maps to the car. Which appeals to owners that don't have that option, like a GTR nissan or something.

Is this in regard to power fc? There are 3 settings on power fc for retarding ignition at any 3 chosen inlet temps.

And as far as power fcs go they have a 20x20 resolution so there would be tuning points every 500rpm if you chose to go to 10,000rpm or every 400rpm if your grid only went to 8400rpm for example. And with the honda power fc you get the two extra 20x20 injector maps for on and off vtec so you only need the target rpm in those ranges so a lot more fine tuning.

Download that for a demo if you are interested. And that's just the features fc-datalogit have cracked - apparently there are more with the genuine software that ST Hitech have and maybe one or two others in NZ (sux that it isn't readily availale but the datalogit stuff is good enough).

I like power fc because it's simple, robust, reliable and many people are quite happy tuning them.

Forgot to mention the grip of cars from, drag, drift, circuit that use them with good results too

<- has a pfc It sucks incredible cock that it doesn't have native datalogging though, if I was serious I would probably ditch it because of this.

And I believe www.totalp.co.nz have the software also...

[Coupe-R]

wicked someone that tunes with these has posted!

Hmmm either that autospeed article is wrong, or the nissan power FC doesn't have ignition retard.

Shame apexi doesn't release english tuning/datalogging software???

Just to give a digg, stock honda ecu has more than 3 points for IAT offset

I say again u WON'T get anymore power going to hondata, trust me!
(unless the tune is better)

Excel is english... but I wouldn't know would I
