Me being very pissed at my car lately I've been doing the usual cry baby thing. Instead of trying to find out what is wrong I intend to cover it up with money and bling bling mods. Seriously the lean problem my car is having lately has got me thinking into scraping my VAFC for a Hondata setup. It might help my problem out and is just better in general.

1. Hondata S200- $295
2. P28 ECU from classifieds around- $130-$150
3. Kenji adapter harness- $150 (or something close to that)
4. DSM 450cc injectors- $100

That comes out to around $700. Then I could sell my stock ECU and VAFC to drop the price down to $400-$450. Sounds like a deal to me.

Is there anything I'm missing? I'm guessing Hondata can run any injectors correct?

 

I understand the reasoning behind the Hondata, but why the big-*** injectors?

because hondata can run them without any problems and they are cheap. Well the size at least, not sure if them being DSM injectors would change that.

 

no need for 450cc. 270cc, or even stock should do you good.

edit: that is a good price. from what i hear, DSM just makes them pack an extra punch.

 

I can get the skunk2 harness (I know the individual who makes them for skunk) for 120

what extra punch? 270cc != stock?

450cc's == dumping lots of extra fuel to a motor which probably doesnt need 450cc...if the stock fuel pump can even keep up.

unless of course, I am a "guines"* and am missing something

450s are monster size for an N/A setup. I even had a problem leaning out my car with a turbo setup and an AFC hack with DSMs. 270s-310s and a good tuner would be good enough.

 

but Hondata can run any size injectors. It won't be dumping my car with gas if Hondata does it's job correct? If I'm not mistaken SGT runs 440cc's on all of his NA setups.

I know just slapping in 450's would be WAAAAY to much fuel, but since I can get them for a good price and hondata can handle them why shouldn't I?

because you don't need them I use them on my turbo setup...but on NA, total overkill!!! stick to stock and get somethin else with the cash...your car will never go beyond 50% duty on those injector...A REAL WASTE!

 

Would too low of a duty cycle ever be an issue on an injector? 450's just sound like overkill for your setup. True, Hondata can do whatever it wants to with them, but I'd be concerned about some physical limitation of an injector that size.

I'd imagine Steve has a need for 440's.

 

if you choose too large of an injector the spray pattern will be poor

 

1. Hondata S200- $295
2. P28 ECU from classifieds around- $130-$150
3. Kenji adapter harness- $150 (or something close to that)
4. DSM 450cc injectors- $100

Don't forget labor to have someone socket the ECU for you if you are not able to do it yourself.

 

dont go with 450cc, way too big. if you dont have something to tune with from the start, the stock ecu map will not be able to run the car. Trust me, I found out the hard way. even if you plan to run hondata, you can lean it out, but you still have a crappy spray pattern and u wont get the power you should be making, not to mention the stock fuel pump will be struggling. I went with 370cc instead and Im still running very rich on my NA setup and I need to lean it out.

if you get used injectors, make sure to clean and recalibrate them, 450's would be too much unless you plan to turbo it or build n/a setup, even if that, don't install them until you get the setup done. 310's should do the job, - it all depends on whp you want to run..

 

i have a set of RC 270cc ill sell you.

 

check out the calculations from rc's website to get an idea

I think the DSM 450 are only good for 240 hp at 80% duty

 

someone quickly explain duty cycle please.. i think i may know what it means, just want to be sure

 

450... bah!

Ed and his 850's

On subject, how would prelude injectors due?

Duty cycle refers to the amount of time an injector is held open vs. the amount of time available at a certain rpm before the next injection event happens and is expressed as a percentage

80% being the most you should run safely

 

theres also a/f ratio, which isn't addressed at rc website.. - thats if you tune rich
also, rpm.. our cars tend to rev a bit higher than average.. like 9K and up..
