Ok cool....Thanks

Looking forward to completing this list, put a CPE intake on a couple weeks ago and my RV6 DP just arrived today. Flashpro is already on the car, looking at injectors next. It may be a little while before I decide to pull the trigger on the injectors, should I go ahead and get Vit to tune it with the intake and DP now is what I'm wondering. I know it'll be an additional $100 for a re-tune after the injectors go in but I'd like to experience it for a while with these parts. Wish Hondata would allow for speedo correction as well as MPG calculations through the stock interface as they've done on some other cars.

get the injectors now and get them done otherwise your going to max out the stock ones.

NBPDC505

Thanks, after looking over a datalog and seeing MAF as high as 4.8v and injectors at 98% duty cycle I see now I shouldn't wait. Need to talk to you about a 3.5" intake soon also it seems.

wspy

Is that 98% with the downpipe installed...or what?

NBPDC505

Yes, and actually after adjusting the tune to be at ~11.8:1 corrected AF throughout the powerband the injectors are at 100% duty from 6100-7000 rpm. There must be some headroom in there as the AF doesn't get any leaner despite duty being listed as 100% for such a spread. Boost targets I have set to 2.0 across all cells. Just for reference I have the catted version of the downpipe, shouldn't be a big difference from the non catted version though. Didn't want this car to smell like my supercharged rsx does at idle and redlights.

wow. i guess some new injectors are a must before you do much else then.

wspy

So if you were to go back to the stock intake (remove the CPE), what do you think the injt duty % would be at?

I know that's going backwards but was just curious.

The first guy to install a downpipe, back in '09 I think, was the only mod he had (made it himself)....That was a night n day power increase

New 2007 RDX owner...(last Friday) with 93,000. I am trying to educate myself as to beginning mods. Any links to threads to help would be awesome!

I had a 2000 Ford Lightning for several years (kids take the fun out of cars). I had many mods on it before I sold it:
Custom Tune (Street, track & highway)
4 lb pulley
FactoryTech valve body
Single Blade Throttle body
Fast Air Kit to modified stock air box with K&N drop in filter
Belltech drop shackles

All equaled dyno of 360hp.

well I'd recommend getting your tuner selected first. once you've picked a tuner discus power goals and ask them which injectors to use and get your injectors and flashpro injectors and tune as a bundle. they may cut a deal might not. if you're local to pa or near by id be happy to give you a ride in mine. so you can see what the upper limit of the stock based components are.

Lol, think twice; and weigh your options!

Hello Everyone!

I've just gotten a 2012 RDX and i'm wanting to get a Flashpro. I see that there is a CARB model for 495 that i'm considering as the only mods i see myself doing would be flashpro, intake (probably just throw a drop in k&n filter in) and maybe eventually an rv6 downpipe. Is the CARB model for me or is the full version of Flashpro recommended? I've been searching the forums for a few days but haven't found this brought up, apologies if it's already been addressed!

Thanks!

I really don't have a goal, it just seems like the base hondata flash is a no brainer. I'm thinking the farthest i'd ever go is what the stock fuel injectors can handle. With that in mind, i'm wondering if the CARB flashpro will do everything i'd need. I live in Minnesota and drive a lot for work so 91 octane is all i can count on finding when i'm out in small towns. In regards to "bang for your buck" the carb model is cheaper and if it does everything i'd need would offer a better value. I think upgrading the cam is way past what i'm looking to do but thanks for the heads up!

Hey which injectors did you use on your RDX ??

1000cc DW but in talking with some tuners they aren't fans of them as there seems to be some issues with the injectors being "matched" with regard to flow.

Thanks wrench

I'm thinking of this list:

-RV6 Downpipe (high flow cat version)
-ETS IC

I already have a K&N drop-in filter and FlashPro (with just reflash uploaded). My goals are to give the car more stop and go grunt. I do not track this car and never plan to, I only use this thing for the daily grind. I hardly ever go near redline, I spend most of my time shifting between 3 and 4K RPM and I only WOT off a light once in a while. With the (2) things I already have, would adding a downpipe and ETS give me a noticeable upgrade in low and mid ranges? I've read in another thread that the stock injectors might not be beefy enough to handle these (4) things I want to have, would I be ok adding the DP & IC to my existing setup without upgrading anything else?

my opinion, you're going to run lean( notenoughfuel) I'd recommend injectors and a good tune.

I have a catless rv6 downpipe and I wanted to know if new piping in a new muffler will actually make much of a difference

x2lacrosse

@wrench

I know you're one of the few performance gurus here, so your feedback is appreciated.

Would the 'lean' condition be due to the IC? If so, would just the downpipe be safe and would I even feel it in the butt dyno (in day to day driving)?

Lc46em

It will make a difference nothing astronomical those cats slow up your flow rate one benefit is faster spool now it's not going to be like upgrading to a newer turbo but noticable. I just upgraded my exhaust to 3in piping with a magnaflow muffler and a magnaflow resonator just waiting for the weather to break before I do the catless downpipe and midpipe install.

x2lacrosse

Thanks 4 your thoughts. So the lean condition referenced by Wrench, is that caused by the IC on stock injectors? If not and you had to pick just one to go w/ my existing setup, which one do you think the butt dyno would notice more (in daily driving)?

Lc46em

The stock injectors are fine for a stock setup once you start modding and deleting cats you run lean if you plan on installing the catless downpipe that alone without a tune will cause you to run lean. As far as gains honestly both make more power a bigger intercooler will flow more air and the colder the charge the better performance. If I had to pick off my experience with my Subaru the catless down pipe made more power than when I went front mount so I mean every car is different and every tuner is different.

Lc46em

I can adjust trans and shifting and all types of sh*t
The stock ecu on these is crap I mean hondata really was limited in what they could let you modify which sucks. I'm working on my 6.2 tune on my truck and I have more options with that it's sad .

TheWrench116

he's already catless 1
spending 7-900 on an exhaust will make way less power then similar money on a tune.2

Lc46em

A tune will get you more power no question about that. A tune with full exhaust with ger more power. And wrench you can have exhaust made up for half of what you said 3 in from cat back was 300 plus my magnaflow setup .

muffler and pipe thats mandrel bent cost half that. there are other areas that are much more cost effective to spend money. hence the thread title. MOST bang for your buck... that said ive got a 3 inch turbo back on mine. its loud and the thing droned until i added a few resonators ( more $$$) so between the 2 70$ resonators 100$ muffler and 500$ worth of mandrel bent pipping maybe made another 10-whp?.? VS a tune picking up 40-60...

HONDATA flat out dropped the ball. they stopped developing this platform. maybe they will revisit it. i'm not holding my breath. i was a tester for them through a tunner then they just stopped trying to unlock more things for us.

the list of things we need are SPEED DENSITY fueling and RAISING line pressure in the transmission SCALING a 4 Bar map sensor also and finally FLEX FUEL SENSOR.

Time to contact Ktuner

Lc46em

Wrench have you built anything besides a rdx ???

Lc46em

Tuner vs exhaust vs tuner with exhaust lol difference in power numbers. Best bang for your buck is get a real tuner who knows what he's doing

CSmoney28

TheWrench116

iTrader: (1)

and with a tune you'd be making more power.

as far as builds. I've been to the dyno enough with this vehicle to know that there are other places to spend money besides a catback.
90% of your exhaust gain is from going catless on a stock turbo. The complete list minus a turbo upgrade doesn't flow enough up top. You run out of turbo long before the exhaust becomes a resriction. If you want proof look at Bill, he's running an upgraded turbo on the rv-6 downpipe and a factory cat back. He runs 10psi across the board due to tuning issues that hondata has yet to fix. But he'll vrake 300 wheel horse power long before your 3" exhaust on a stock turbo.
If you don't understand that I can't really explain it any better.

Lc46em

Lmfao wrench just because your built your RDX 6 years ago doesn't mean shit neither does your Dyno time. You sit on this forum pretending to know stuff and use your smart ass remarks to try and justify your old build lol. I have put together more cars in the past 2 years than you have in your lifetime. I have 5 cars sitting in my driveway the RDX I've had for 2 months lol and have over 3k into it. My ej207 Verizon 7 cost more than you have in the build. Don't come at me side ways little boy

Lc46em

Wrench you tend you put your cheap ass build on top of a pedestal and than think you know more than people lol because Dyno time ? I put my own shit together lol I weld my own exhaust I build my own engines and I tune my own shit . I don't go buy my stuff I built it hence built not bought son. From now on when you address me come correct or shut your mouth.
