I'll make this new post & then merge it into the other thread in a few days...
03 CLS 6MT, mods in signature.

Ok on my car these don't do much. See dyno graph.

Before
HP 252.85 TQ 218.33
After
HP 252.79 TQ 219.39

Maybe it's the FL weather, Maybe it's the dynojet, I don't know. My butt dyno thought there was something but after the ECU adjusted it feels the same as it did before the install.
I did do an after dyno at Power Rev Racing's shop the day I installed these & that yielded 265/229 but I don't have a before on that dyno to compare.

Everything is working on my car & I'm running 235-45-17 tires on stock rims. The other cars I've seen dyno'd are 225-45-17's or stock size.

I'm thrilled my car is consistent in the 250WHP range though. That's a great number for just bolt on's.

Did you uninstall them and then reinstall them for this dyno? (I know that seems like a dumb question, but I'm still stumped). We have a pretty much similar set up, except for exhaust, mugen cooling mods and of course that your a 6-speed.

I did a before dyno, then installed them then dyno'd again. The chart is overlaying the before run with the after run. Notice the dates & conditions at the bottom.

are there any other 6speeds in line to dyno the mod?

but there is butt dyno right? lol

i wonder how much the restocking fee is...

Your running rich too, you should be doing around low 13's maybe around 13.5 before IMRC to about 13.0-13.2. Unless for some reason thats too lean for you and the ECU pulls timing.

Just do the dynos again if its not too much of a problem for ya.

fuzzy02CLS

iTrader: (2)

That's how my car has always run. The CL runs rich by nature. Even a stock car.

The fact that my car ran such high numbers on P2R's dyno is a concern. I'm not sure why it ran a 265/229. His dyno is a different brand dyno.

Accord_V6_400m

iTrader: (1)

Yeah figures as much, I could already tell it was a different brand. Get your car tuned my car used to be running in the 11's before I got the NEO and tuned it.

After you did the initial dyno, did you reset the ECU and drive around for 30 or so minutes? the ecu needs to adjust AFR to compensate for more air... when I installed my P2R TB Spacer and dyno'ed without resetting the ecu I made the same power but I was running leaner due to extra volume... there was quite a bit of power to be made if the mixture was richened up from that point.

iTrader: (1)

i thought the ecu resets itself no matter what unless u using a aftermarket chip and even then !!~~~~

disconnecting battery for 15 mins after mod = resetting ECU for new learning pattern

however i beleve some believes it resets itself after a couple of days

gc86

If left untouched the ECU will eventually adjust to the extra air volume and compensate with more fuel but if he just installed the plenums and did a dyno run he wont see any gain at all, even a loss in power wouldnt be surprising.

fuzzy02CLS

iTrader: (2)

The before & after dyno's were a week apart. ECU had plenty of time to adjust. I drove a few hundred miles.

Last I checked there's nothing made for tunning for a 6 speed. Nothing that doesn't require work to make it work.

I'm not into messing with wires or extra sensors.

I'm running 93 gas & am not too lean, The car runs great. The power is all streetable. I'm happy with this.

phipark

damn, can't see the dyno for some reason

i would think you would see about 10whp/10tq with the afc neo, which is very affordable and with a boomslang harness is entirely plug and play.

in regards to these plenums... it appears the only way to get gains is from a tune. IMO this are only as about useful as your throttle body inlet size.

fuzzy02CLS

iTrader: (2)

Here's the after dyno from P2R's shop... Note all dyno #'s are in SAE format. STD number were a tad higher on all.

TCM 01 CL-S

I'm puzzled, because right after the plenums I got an 8whp, 13lb/ft gain without the Neo being touched.

gc86

Im puzzled aswell.. and the inflated numbers on P2R's dyno are wack?

poisx7

iTrader: (1)

suspect ....... well something does nt add up.

poisx7

iTrader: (1)

whats the biggest TB one can put on ou cars, maybe i shud just try a bigger TB + the already installed CAI & Headers My guess is it Might be able to make some power.

What do u guys think.

I believe the bigger TB still keeps the same outside diameter. so that all other mods like the p2r /gaskets or spacers would still FIT.

wht do u guys think ?

typeR

inflated by whos standards? it is not wise to compare one dyno to another... i dont understand why a before and after wasnt performed same day as install?

fuzzy02CLS

iTrader: (2)

Because no one is open on a Saturday & the conditions were not the same after I installed them. It was rather cool for FL.(10-15 degree difference) I didn't want the cooler weather effecting the results.

iTrader: (1)

trust me change tire size to 205 40r 17 and you will love it . just watch out for pot holes

TCM 01 CL-S

Why the hell would you do that? The stock 215 is already a pretty narrow contact patch.

Accord_V6_400m

iTrader: (1)

As opposed to a different dyno

rjurado_1215

do those plenums affect after market injectors? mine sit a little higher

Accord_V6_400m

iTrader: (1)

No, they do not

typeR

so why not pull the plenums on this most rescent dyno , then reinstall? dynos even same one are best if the part in question is tested before and after on the same day

J32.4.Life

Thank God I didn't jump and buy these.

Don't have the time right now. And dyno's are $. $75 for 3 pulls, it's getting expensive.

PowerRev

Why dont you come to my shop when you have the chance. We will uninstall the plenums. Dyno the car. We will then reinstall them and dyno the car again. This way the conditions can be the exact same.

I think the main reason your not seeing a gain from the plenums is because the ecu is adding fuel and pulling timing because of the added air fuel. When you add a mod to these cars. Most of you say you have to wait until the ECU adjust. But what you will notice is if you install a bolt on, and dyno right away. You will see a bigger HP gain. The reason being is becuase the ecu didnt adjust yet to the extra flow, and the car will run alittle bit leaner resulting in a HP gain.

What happens is that when you dont have anything to tune the car. The ecu eventually learns the added flow and matches back up the fuel and timing to make it back to what it thinks is stock. When you have something like a VAFC, or some other type of Piggy back system. It actually overrides the stock ecu to keep the air fuel where you set it to be.

For example, if you turbo a CL on a stock ecu. Without anything to tune. It will start running worst and worst every day. But if you have a Emanage or something. It will always run how you set it up to run.

So in this case. If you come back to my shop and we do both b4 and after. you will see a gain, but you will in all honesty want to get some kind of something to tune the car. You will not only be able to make more HP, but also be able to always have that power there. This rule does not only occur with the plenums, but will be the same with headers, intake etc. you will actually see a bigger gain right after install, because stock headers are so restricted, that even after ecu compensates from aftermarket header, that you will still have some gains, but not as much as right after install.

Older ecus didnt use to do this. On a newer car like a 2006 Civic Si for example. Alot of people install intakes on the cars, and they go and dyno a week later, and find out that they have the same HP as they did before the install. But thats only becasue they dont have any kind of management that will not let the ecu go back to stock.

PowerRev

But if you have the time, since you are local, i would really like you to come by so we can do this b4 & after dyno. I dont want to have any disappointed customers from something that I know works for sure.

Also just a quick note. On a butt dyno, when you can feel something, normally means gains are there. Reason being is becuase when you do a specific mod to a car. Like exhaust for example. It sometimes makes mid range gains, so where you can be 60% throttle and can feel more HP. Sometimes gains are more in the daily driving situations rather than full throttle situations. So mid ranges gains can be there, but not Peak numbers. Not saying this is the case. just a side note.

If you guys can dyno the car from 2K at least. I want to see the low end gains of thi product since the car factory limits the volume of the IM to a certain amount before the IMRC 3800 switchover for a reason so I want to see how the net increase in volume affects the velocity of the air at low engine speed operation.

fuzzy02CLS

iTrader: (2)

I'll keep that in mind after the holidays are over.
I stated from the beginning these are on MY car. Someone else's car may have different results.
Another dyno test would be conclusive I guess. Just need to find the time.

On a side note, they do look good actually. I've gotten used to the under hood look. The guys at the dyno shop were raving about the quality & how they look good.

I agree with everything PowerRev had to say about our ecu. Also, defenitely take the time to go to his shop so that they can show you what these plenums can do. Then in time, invest in a piggyback that will allow for tuning.

Accord_V6_400m

iTrader: (1)

Got to agree with Chris and Power Rev, just get your car tuned with them and do the whole dyno procedure once more. Im suprised as many people as there were jumped on these so quickly and said they new these plenums were junk Lets just get these retested and unti then everyone can hold their opinons/accsations. These already made some great gains on an auto so so far so good.

Mike

what would you guys recommend for tuning? the neo or emanage? didn't your neo reset? after a reset can we plug the settings back in and roll?

TCM 01 CL-S

For the record: my neo hasn't reset since it was installed. I am using the boomslang harness.

Accord_V6_400m

Its weird Apex'i couldn't find anything wrong with it, its as if someone got into my car and changed the high throttle tune to all +5 figures.

Just right down the tune in the space provided for you in their owners manual and you should be good, I just never thought about doing it before this.

Emanage is more advance with cool ignition features and 16x16 maps. AEM FIC has 21x7 maps but not as many gizmos as the GEU, however Greddy as you might have noticed from all the threads and differnt boards has horrible customer service, they can't even seem to help themselves let alone us.

But yeah you can just change the settings back and roll, or like me roll with the rich settings. The low throttle setting s dont really seem too affected 0 and -1 values, although I don't remember what those values were and how lean they might have been. The Greddy Emanage has been known to "unclamp" the MAP voltage SIRSIG is a example of this, the MAP voltage was off and the car was pulling timing like crazy.
