Tuned DC5's with I/H/E Hondata or Haltech

[maintain]

Hey guys,

Just a quick question and out of complete curiosity, for any dc5's out here how much are you making at the wheels with any particular header/intake/exhaust along with a hondata or haltech ecu ?

I've read most are making approx 145ish but i'm keen to know what set ups you guys have on your car ? I've also been reading through the members rides section to get a good idea

Cheers for any input

Made 135kw atw. Seems low, but the difference it made after the tune was pretty substantial. The more important thing is that you have a before and after dyno to make a true comparison of power gains (whilst trying to keep all variables constant). Otherwise looking at power figures is more of a dick measuring contest lol.

Haha thats true. Awesome! cheers for the input mate. 135 is still very good i for sure would be happy with that. Unfortunately i was unable to run my car for a dyno before i put those mods all in one go but would be interested to see what the k20z makes.

Don't get caught up with the peak number when comparing dyno charts. Yes it looks good to have a bigger number, but each dyno will read slightly differently and different results will be seen day to day on the same dyno

What you want to look at is the torque curve. This will tell you how "flexible" the engine is and if a particular combination of mods make more torque over a wider rpm range. This will make the car alot quicker point to point.

Lastly, you also want to look at how the power and torque curves meet. Ideally, you want to have power coming up fairly linear and torque dropping off after the power curve has passed over the torque curve

I got 139atw woth kpro/injen cai/toda header/spoon n1

The peak power increase waant much in comparison to the i/h/e setup with stock ecu: 118(stock ecu) and 139 (kprp)

The drivability was amazong though. I change gears at 3k rpm and on the upshift u feel like u are on the power roght away. I averaged around 9.6L/100km. With the kpro it went to around 8.9L/100km. So i even got better fuel.consumption thanks to the upgraded ecu.i think u will be finding the average is between 132-140 atw eotht he ihe setup

Hey guys, Im also looking to get a KPRO second hand but I am unsure of what part I need eg, harness, prb ecu? etc. I also own a DC5 Type S 06

[knobosaurus]

If you're buying for an 05-06 type s you'll need a prb ecu which is specially modified for the kpro along with an adapter harness and possibly an 02-04 primary o2 sensor. Alex, correct me if I'm wrong.

[ggwpty]

^ Pretty much spot on.

Read here for more details - http://www.hondata.com/kpro0506.html

You might also want to consider Haltech. It's just plug and play (you don't need a harness or new O2 sensor) but at the same time it's not as popular as K-Pro for the DC5, so might be harder to a find a good tuner. Go with whatever tuner you are going to feels most comfortable with.

Just get a haltech LiteX

PLM 70mm Headers
200cell HFC
Invidia q300 70mm Exhaust
Hayward/Jenvey ITB
HALTECH ECU

160kwatw
290nm Torque.

Because of the Itb. The mid-range is ridiculous! My top end kinda dies down after 8100rpm. But thats because i have the longer itb set up.

Am kinda curious to see what i would have gotten after a tune with just a CAI though..

If you're in NSW Adrian from SAS is the guy to talk to. He knows plenty.

[eLtrix]

^ Wow thats some nice torque numbers! Stock internals?!

[BOMDC5]

Stock internals.

No dyno sheet but my full weight DC5R on heavy 17" wheels ran 101 MPH (crappy ET and 60' I know) with Gruppe M/Toda Header/Amuse R1 exhaust and Kpro:



MPH of a touch over 100 seems to be pretty standard for I/H/E + ECU DC5s or EP3Rs.

Hub or roller dyno? At what RPM is peak torque?

Roller Dyno.

And I can't remember exactly and i don't want to quote the wrong figure. Will confirm tonight
