Alright guys, let's see what happens today. At a bare minimum I hope my torque curve flattens out a little.

Good summary, will see how the final result is with essentially full bolt-ons.

Looks like about 25whp gain from everything except for spacers/TB bypass/tune. So we'll see how much the tune adds in terms of whp.

Very expensive $4000 for 25whp gain so far...so should be good reference going forward to others who want to mod base 5AT TLs and expected gains for the dollars spent

TacoBello

The 5AT TL loses 53hp from the crank to the wheels?

Is it just me, or is that dyno reading a bit low?

TheTLProject

It's a dynapack. Since I'm getting out of here early due to having the wrong harness, I'm gonna try to find a dynojet to do today.

TheTLProject

Also it's been brought to my attention that I have oil leaking from my oil pan and VTEC seals. Subframe and oil pan are covered in oil and dripping to the ground. That's what they said anyway. I haven't seen a single drop of oil where I've been parked.

Just clean it up later with carb cleaner. In for the dyno numbers/sheets

TheTLProject

No point in dyno since nothing has changed enough to make it worth spending 100 bucks on a run. The tune can't be done today. I need the correct harness. FUCK ME. Oh well. It's gonna be a while till I have more money to finish the project.

TacoBello

Patience, young grasshopper

If you get it all done super quick, in six months you'll be kicking yourself for having nothing left to do to your car enjoy the journey!

foxriderar77

interesting finds, I would think the new tune will have some decent gains

TheTLProject

The technician was saying all that officially will be adjustable with the FIC is only air/fuel ratio. Nothing more. Nothing less. Guess I better start saving for that adapter harness....sigh

You'll get some gains by adjusting AFRs, just won't be drastic gains..

Guess your saving for Hondata? or liquidate assets and get a 6spd TL-S

TheTLProject

Can't use hondata on my year/transmission combo. FIC or J&R ECU are only options. I'll be lucky if I get 5300 for this car. That's what I paid for it bone stock.

If it makes you feel better, my car is even worse to tune (06' RL). Think my only option is the FIC.

TheTLProject

Your car is also way more powerful out of the box if we are talking about the newer 08-up ones. I want your cams.

Many of us have (or had) this issue. It costs about 650 to replace (that's a cheap quote), and i've pushed it off since all I do is check my oil regularly and add as needed.

I have no oil spots when parked and have always had to fill up oil, but when I got my TB job done they mentioned that leak. i told them i don't see spots parked and they said it mostly comes out under pressure when driving.

TheTLProject

Yeah the car drives amazingly well and not a single engine problem. Stock acceleration times were better than advertised back when I first bought it but I can attribute that to the BFGoodrich GForce Sport Comp2 tires, I will definitely be buying those again.

Mine has a J35A8 (05-08). The 09+ has a J37A2.

If your interested in J35A8 RL cams shoot me a PM

sooo where is the dyno? video? Car doing better?

He said he had the wrong harness so no tuning, no dyno

TheTLProject

But I do have an exhaust clip. I put a resonator on and it removed the nasty mid rpm rasp I had. Tuning will be in a few weeks. FIC is mounted inside car not wired up for now.
