I wonder if the 2009 TL non-AWD has been detuned.
The accord 3.5L has 271HP and the 3.5L TL type S has 286HP.
Do any of you think an ECU upgrade could take the HP up to 300?

 

You need to increase the bore and stroke too since AWDs are 3.7 liters. hahaha..

Seriously, e-shift performance has been making high flow cats that increased 3Gs for 20 good HPs... none for the 4Gs yet. You could probably get 20 from an intake/exhaust combo too.

 

There's no way you'd actually feel any difference an extra 20 horses would bring. Save your money for other mods.

 

Intake ==> around 7 HP ==> $250
cat back ==> around 3 HP ==> $800
ECU ==> 10 HP ? ==> $750 ?

total 20 HP, $1800

I agree that it's probably not worth it, but it feels like there
is something programmed in the car that deters the car from accelerating.
It feels like the car starts to accelerate and suddenly the power decreases
and it feels like Im driving a tractor.
Why does the automatic NSX feel 1000x faster when it has less power than the TL? Is it because of weight? If I totally stripped the TL (seats, spare tire, a/c, etc..), would it be as fast as the NSX? Or is the NSX just programmed to accelerate much better?

 

Yeah, the NSX is close to 1000 lbs. lighter than the TL.

If you wanted HP, you should have gone with a 135i with 3.0TT engine. Just with a $700 chip mod, you can produce up to 400 engine HP and 300 to the wheels.

 

There will be products soon enough. It's a brand new car. I think we will see some intake and exhaust stuff. I would like to see a lightweight pulley as well.

 

Simple....If you want faster acceleration, wait for the 6 MT 4G.

 

1. the NSX is RWD
2. the NSX is Mid engine
3 the NSX has less drive-terrain losses
4. the NSX has a much higher rev limit
5. The NSX is made out of aluminum and is tons lighter
6. The NSX motor is titanium and thus can wind up faster.
7. The NSX was engineered to go fast with little HP.

 

The 3G TL has the same tranny from the 2G so Acura has detuned the engine during the lower revs so the 3G would not have the same tranny problems.

 

this is a semi incorrect statement. The very early 04 TL's had the same trans as the 2G, then they implemented v2. of the trans. This was used until mid 2005 where it was changed to a new design that provided even more lubrication and cooling. in 2006, acura added a torque limiting algorithim to the ECU to combat the bad torque steer that people complained about on the 2004 and 2005 TL's. It limits torque in gears 1 and 2 only when at a stand-still to my knowledge.

 

HP/lb - sums it all up
