So, I've got my simple first-timer build going. Want to make sure I'm staying on track in the correct order.


I've requested that my dealer order the Hondata heatshield, as well as Deatsch Werks 800cc injectors and a 65c fuel pump.


I've installed the Hondata reflash and have my Flashpro. I've replaced the intake snorkel with 3" performance intake ducting, the air filter with a K&N drop-in, and I've just ordered the RV-6 downpipe with high-flow cat. I plan to retain the stock catback.


My questions are this: At this point, how necessary are the injectors and fuel pump? What could I get out of them, with everything listed and a proper tune at a dyno? What order of installation is recommended? Should I go for an A/F ratio of 14.7 at the end? How recommended is the ETS top-mount intercooler, additionally, at this point? Thanks for your advice.

 

So, I've been advised that injectors and pump aren't necessary for what I'm planning, which is just a (somewhat) more opened up intake, RV-6 downpipe with high-flow cat, heatshield, and reflash.


So far that seems to be a decent total investment, coming in at about $1600 all told, shop-installed. I can datalog from that point.

 

if you plan to have it tuned and not really mess with anything else then youre fine with stock injectors and pump, if you plan to raise the boost alittle then 600cc is fine.. if you plan to go wild 800cc and pump are probably going to be needed.. not sure on our fuel pressure regulator no one has mentioned its limits yet but that should be in the back of the minds too

 

I suppose I'm still not entirely sure what my options are with just the opened intake with drop-in K&N filter, flashpro and hondata heatshield, and RV-6 downpipe. Beyond there there's more bolt-on mods - I could go see how much Ken boosts his but that might be more than I need! But is it correct to guest much more boost shortens the life of the turbo?

 

ken upgraded his turbo. your better comparing against me or hypnoti. and then only after vitviper and us get the tuning sorted out a bit more.

 

yeah, I noticed that you had the injectors done. How close were you able to get to the duty cycle with just the flashpro? Or am I treading onto the 'go read your post' part?


I've got a tuner who's interested in tuning it himself on a dyno. I could certainly post logs for comparison once I start properly datalogging.

 

I did everything in a matter of days and it all went in and I went to get tuned.

 

you've got the 800cc injectors, right? What boost pressure do you run?

 

yeah still some tuning to figure out im at a hault untill hondata opens things up. maxed out on stock injectors. raising boost even not at high duty cycle is up and down sometimes retards sometimes lets it knock the ecu logic is tough especially with drastic weather changes here in co.

 

14 psi spike to 17-19 on a shift @WOT

 

Ah, so, it seems based on this information that getting fuel injectors would be premature, if I'm not going to be upgrading the turbo. I'm planning on just heatshield, removed snorkel (replaced with 3 performance ducting, K&N drop-in filter, and RV-6 downpipe with high-flow cat, all tuned with Flashpro. It seems like I'm not going to run into the max duty cycle with that. All right, that's good to know.

 

not like you cant pop them in later.

 

That's certainly true! Anyway, I'm wondering if I should have it dyno tuned after getting the downpipe, or just try one of the maps and datalog.

 

Do you run that 14 PSI at all RPMS? Or do you run on a curve down to like 10 (the stock setup is like 12 down to 8 right?)

 

So, I'm getting the downpipe installed on Thursday, and at that point I'll be running the opened up snorkel with k&n drop-in and the rv-6 downpipe. I presently have the stock hondata performance reflash. Recommended to change it with the flashpro?

 

Do you own a flashpro or did you have a dearler reflash your ecu?
How much are they charging you for the rv6 install?

 

I own a flashpro.


He's only charging me $50 for it - he's the guy who sold me the flashpro, and he's kinda into the RDX. I'm doing a remote start with him, which is kind of his bread and butter, and some brake work covered by service contract. He's more than happy to do a little performance work on the side.

 

I wouldn't say fifty bucks is his market price - he's doing a bunch of other stuff after all.

 

ETS TMIC is a must.

 

Sure but aren't they like $900?


Got to pull the plug at some point...

 

Wow.. he must be a great friend. That is dirt cheap for the down pipe install.
From what i have read its a real treat to install!

DO you have a reputable tuner with an AWD dyno near you?>

 

Yes there's a very reputable tuner about an hour drive away

 

How much of a 'must have' is the TMIC?

 

damn near mandatory unless you get creative and fab up a front mount. or start spraying water meth.

 

and yeah I'm at 14+-1/2 around my shift point 7200rpm and I'm spiking 17-19 when I shift. so it mooooves.

 

Would you say the ETS intercooler goes hand in hand with the injectors? IE, increasing the boost means that you're increasing the temperature, you need cooler air, etc?


I'm considering tuning it with just the intake, downpipe, and flashpro and see how I like it for a while. Intercooler + injectors + pump looks like it would be another $1500 or so.

 

I'm looking to go front mount. that is my long term goal. I wouldn't be able to run what I'm running if I didn't have the capacity that the ETS intercooler provides. if your running more boost then it is even more important. I knew that one day I would be running a bigger turbo capable of more airflow and higher pressures. I'm very happy with how the ETS intercooler has preformed being its only a top mount. I'm looking to get a more is better approach with the transition to a front mount. more surface area better cooling higher boost pressures 20+psi and the stock location wont work for this.

 

Ah, I see. Well, I'm going with an approach of trying to get the most efficient mods to have a little more fun on the road and stop there.


Perhaps, good sir, when you're ready to go for your front mount, you might sell me your used ETS? Maybe I'll be ready for a little graduation then.


So in short, if I'm not upgrading my injectors, can I get away with not upgrading to the ETS?

 

and from a log that hypnoti sent me he was at 72% duty cycle on just an intake and flashpro ... hmmm seems like your going to need more injector soon.

 

mods would get grouped like this flash pro + injectors
every thing else...

 

so that 72 percent intake and flashpro - what about just intake, flashpro, downpipe, heatshield? Then have that setup dyno tuned?

 

that way I can just ignore the problems with raising boost much, after all, keep boost at 12psi max, and get injectors and tmic later, if I please. If I don't just get an RDX when they bring the turbo back (which seems certain)

 

Looks like based on the Hondata website I can safely run the injectors up to 85 percent, I suppose. He was at 72% at 7200 RPM?


I think I'm starting to get a grasp of it!

 

I double checked he was at 78 % that's a hard life for the injectors. the closer you get to the edge of the envelope the more likely it becomes that a thing will fail. your car your build your bills.

 

Well, admittedly that would only be the problem at high RPMS right? This is a daily after all - I'm just going for a little more power on the road.


However, I'm new to this. I don't want to be so stubborn as to be at the 'your build your bills' point. If injectors are a must, then so be it!

 

sorry this was before coffee and food. if you want to get them get them. if you run the injectors hard and they go static you run the risk of having a cylinder go lean (BOOM) I look at it as cheap insurance. way cheaper then a motor. and once the tuning issues are worked out and they will be, you will be able to max out the injectors with ease.

 

no worries man, I appreciate the time you're taking to help me check myself.


So I should be keeping my injectors at a low duty cycle pretty much full time?


So, my downpipe, replaced snorkel, K&N drop-in, hondata heatshield, and flashpro injectors to not be running the risk you described of running too lean? Can't just leave it at the 410s and tune?

 

if you run everything but injectors and set your red line at 4000 you'll be fine. if you want to use the full potential of the factory rpm get the injectors.

 

Well, I was planning to run neither the full short ram air intake, nor the ETS intercooler, nor a full custom exhaust. Just an opened up version of the stock cold air system with K&N drop-in, and the stock intercooler, with rv-6 downpipe w/high-flow cat bolted to the stock system, heatshield, and flashpro.


Is that a mistaken plan safetywise? I wanted get as much power as I could for about $1500 in parts. So that was flashpro and downpipe. Figured I could open up the intake a little, not a lot, by using the K&N drop-in and replacing the snorkel with performance ducting, and the heatshield's also not an expensive part itself.

 

if you touch the boost or even drive hard in the summer your going to have some major heat soak... this coupled with a tune that's not perfect due to lack of fuel = bad times. if your waiting on me to say do the injectors. nike...
