Okay guys here's the first two runs I did with my 2005 TSX 6MT. I only have about 2000 miles on the car, so I suspect much more power later in its life. So far, I have added a Comptech Exhaust, and the Hondata reflash.

I am using a 2004 ECU in my car right now, even though its a 2005 vehicle. So far I've experienced no problems, so I'm sure its safe to do.

Today, I will be adding an Injen intake to the car, and then getting two more Dyno runs done. I will TRY to video the runs, I dont have a vid camera, so we'll just have to see about that. I will however get the Dyno data plotted.

Car: 2005 TSX 6MT Nighthawk Black

Mods: Hondatafied 2004 ECU, Comptech Exhaust, A-Spec Suspension, A-Spec Rims, Rear Spoiler

 

wow.

comptech header makes a big difference apparently. hondata put down 210. i'm sure comptech is happy to hear that.

exhuast - the gains are lower than taewlee w/ injen cai, which is expected.

 

even though he has exhaust, it's proven to do almost nothing, so I would say this is basically a dyno jet of a stock low mileage tsx with reflash.

Too bad you weren't able to get baseline dyno before the hondata flash with jsut the exhaust but still good info! Thanks!

 

Dyno jet vs dynapack, so can't compare directly! BUt you are obviously right about the header. I think a tsx with stock intake/exhaust but new header would make a big difference!

Edit: I'm doing a quick excel sheet of a comparison between this dynojet dyno and one of the other stock dynojet dynos we have. It'll be up in a few minutes!

 

Isn't the dyno Hondata used known to give at least 10 more HP? Not a fair comparison.

EDIT: Owned by the Tinky.

 

i have that exhuast too.

 

this is great and all, but can you add this to the hondata check in.

thanks.

i guess i'm the hondata check in moderator? hehe

can a mod sticky it for me?

 

Jeff at TOV used the same dyno. His mods were DC Header, AEM SRI and Hondata Head Gasket.

Peak HP was 190 and peak TQ was 164. Considerably more.

 

after removing the stock header, i'm not surprised that higher flowing aftermarket yields big gains with hondata.

 

Z! Buy a new header and give me yours ASAP!

 

I don't think Jeff had his car shipped to Honolulu to run on the same dyno

 

I suspect he'll be at 180+ once he adds the Injen.

But as we know, Hondata isn't about peak power. He's pushing almost 174 at 6500RPM

 

I didn't mean literally you asshat. They both used a DynoJet.

 

the TOV TSX runs exceptionally strong, enough that I think it can't be compared to others. Their baseline dyno was more than mine w/ a CAI , and their's w/ a SRI was more than mine w/ a CAI and hondata gasket. Their SRI only dyno was also more than jtso's and stokeless', so they're going to be high no matter what. i'd like to see the TOV on a different dynojet or someone else's on that dynojet to verify that its not the actual dynojet reading too high.

I think tekn0mage's is on par. I dyno'd w/ CAI only at 175whp, and considering he has an exhaust 1-3whp, and reflash 2-4whp, that sounds about right if a CAI makes 8whp.

 

The first post by prov on this page is two dynos, both from the temple of vtec shop. http://www.acura-tsx.com/forums/showthread.php?t=1272 I"m not going to bother using one ot compair because it seems this particular dyno reads nice numbers, even if is repeatable between cars.

Edit: looks like we dont' have any completely stock dynojets other than those two. So i'll go ahead and use them. We'll just have to realize the "stock" line reads a little higher than one would expect.

 

well, tell toda to hurry and make one.

 

sticky this

Sounds right.

Lets also keep in mind that his car had only 2K miles.

 

Caveat the baseline stock tsx is slightly stronger than most and teknos only has 2k miles.

 

His HP curve is flat from like 6500-7600 rpms...that means lots of area under the curve for acceleration..nice!

 

And the results are in! Feast your eyes on this:

Same car. Same dyno. Injen CAI added.

Net gain: + 6 hp, + 8 torque

Overall, very happy with the gains. However, one thing to note... with each Dyno run, the Air Fuel ratio got better and better. The A/F from yesterdays run was mid to low 12's, today was in the 13's, and it was getting better with each run. This could be attributed to the ECU "learning" (note: we did NOT let the car "idle", opening up throttle is about the best way you can teach your car).





I will check in with the Hondata thread next. Since my setup was changing today, I didnt want to post two threads to Hondata check-in :-p

 

FYI... WOT puts the ECU in open-loop mode, which means it ignores the O2 sensor input. So the car didn't really lean anything.

 

So I should've let my car idle for how long? I think I idled for like 4 min then I took it out for some WOT runs.

 

Nice dyno. Just wait til your engine lossens up even more

 

yeah that dyno definately looks yummy. now whenever i am driving my car i am thinking about how much better it would be with hondata... i can't wait to get it.

 

update:

I just love my car gang. The only sad part is... getting on the throttle really turns heads. Everytime I've let it open up, immediately the people turn around to see what's barreling down the road. What a great machine.
