CROME? How much gains? NYPD??

JDM_GUY · Posted: Fri Nov 13, 2009 8:16 am Post subject: CROME? How much gains? NYPD??

Installing CROME on a ECU that controls an engine that has the following mods:

JDM D15B:

Intake
Headers and Exaust

How much of a power difference can I see? 10HP? 15HP? What are the Power Gains?

NYPD???

What other mods do you have to the motor internally.???? are you doing it on a dyno or is it a prechipped ecu with crome on it for your car????

question is vague,at best

peak hp counts for nothing if you have a shitty powerband

also, you have to get it tuned properly to solve the above ^

JDM D15B:
Intake 3" short ram ?
Headers and Exaust 2" ?
bigger TB/FPR 60mm ?
ported head ( was it flowed) ?

did u dyno after these were added ?

sometime *(Headers and Exaust ) can make u loose power if you go to big

Intake is 2.5 Short ram
Headers and exaust 2"
tB B16A/FPR b&m @39PSI Idle
Ported head was not flowed tested.

never dyno the new setup.

did u dyno stock ?

JDM_GUY · Posted: Fri Nov 13, 2009 10:57 am Post subject:

^^ nope.. but i read that at the flywheel its 130 so at the wheels would be 30%- 130.

red_dragon · Posted: Fri Nov 13, 2009 11:41 am Post subject:

not always so

u should make a dyno pull at persent see what u working with

it will suprise u

SO NYPD am i going to see any gains with the CROME?

reiXmann · Posted: Fri Nov 13, 2009 1:13 pm Post subject:

Yeah,you'll see up to 50HP gain with the crome. No tuning necessary..in fact,it will pull just a little better than a stock b16a #Fade in

^^I dont think i will get that much,

instead of the old talk go dyno and get a base

u should look at something like this

from Zex site

Engine: D15 SOHC V-TEC engine
stock block
stock head gasket
stock head bolts
stock valves
stock valve springs*
stock camshaft*
stock connecting rods
stock pistons
stock fuel injectors
stock fuel pump
stock throttle body
Induction Set-up: ZEX™ nitrous system, 100 hp jets installed (82011)
ZEX™ spark plugs (82003-4)
Light Speed Racing intake
Exhaust: Chikara header
stock exhaust system
catalytic converter test pipe
EX Civic muffler
Driveline: MT 20 x 6 x 14 slicks, 12 psi air pressure

red_dragon, Thats what I am looking into, But the guys told me i need to get a tunedECU to dial in the car for the Nitrous.

Pootie · Posted: Fri Nov 13, 2009 5:07 pm Post subject:

well Crome , neptune, eCtune, uberdata etc are all tuneable programs for OEM obd1 ecu's.

Every set up (unless it contains 100% of the parts the SAME) will need to be "tuned" differently.

You would have to tune for more fuel on a shot.

Note: i have had veryy bad results with the B&M regulators ( it's pretty much a stockregulator modded to be adjustable. Buttt it still uses the same diafram, which cna fail under higher pressure ratings)

red_dragon · Posted: Fri Nov 13, 2009 6:09 pm Post subject:

B&M with stock fuel pump works

once u go bigger it pops down ..

my experience .. ever tried different springs same thing

NY4PD · Posted: Fri Nov 13, 2009 9:40 pm Post subject:

B&M fuel regulator fails all the time, Crome will give more horse power yes, depends on the port and other mods you can see anywhere from 10 to 20hp more with mods you listed, but there maybe some areas where the power is slugish, and that is where the dyno comes in handy where you can see the details and you can clean it up for peak power as well as torque and midrange powerband.

just putting Crome on your ecu will work for you yes, but it only get you started and you go from there, you will notice some difference as to more power up topend and maybe more and faster response on the lowend, but that don't mean you all good.

Good luck with the build Very Happy

you may not even make the stock hp expectations which should be about 110 to the wheels without some tuning

you must retune the engine particularly for your setup a ported head on stock camshaft can be good and bad too but the best way to know is to install a wideband oxygen sensor

^^^

he heard you guys... he will be going to the dyno tonight.

Wizard · Posted: Sat Nov 14, 2009 10:17 am Post subject:

you dont even need to see the dyno yet unless you just want a baseline number to know

with a ported head and throttle you may already be running leaner than normal is best you get or rent a wideband sensor and have a tuner make some adjustments right on the street if necessary but dyno would be safer eh

kes_vtec · Posted: Sat Nov 14, 2009 1:31 pm Post subject:

bone stock with just fuel and timing and vtec. when i say stock, me mean everything, but a K&N drop in filter and a 400TT barrel.

go with...

kes vtec is the pic bad

i can only see a white screen is that only me

NY4PD · Posted: Sat Nov 14, 2009 7:42 pm Post subject:

kes vtec the graph dont work, i cant see anything either..

red_dragon · Posted: Sat Nov 14, 2009 9:20 pm Post subject:

guess HP was too high for the graph Wink

red_dragon · Posted: Mon Nov 16, 2009 8:39 pm Post subject:

to pootie and ny4pd is there any version of crome that allows tuning on the fly

No chip burning thing ?
