This is killing me .. anyway to raise the rev limiter 2002 TYPE S
Ok 2002 Acura tl type s .... this car needs another 800 rpm at least ... the car wants to run harder up there and wants to stretch its legs. Now i know theres a main ecu, but is there a secondary ecu that controls the shift points for the transmission?
If so wouldnt it be possible to get someone to write a code for the ecu to raise the limiter ?

im going to call up a buddy of mine he can write any progra up .... but would i need something for the transmission ecu as well ?

it would be like 900=1200 a piece if i do get it to work ... well whos from saying i cant just have an entire ecu program written that matches all the factory settings except for the shift points, and then just swap it out with the stock ecu ... ?
sorta like tricking it into thinking it the same ecu

The first thing you have to do is float your valves, you know when your pistons move faster than the valves can. Oh wait...that's after you raise the rev-limit. I hate to be sarcastic, but if there's ever any way to destroy an engine and void any warranty associated with it, this is it. I believe the guys over at Honda kinda did an okay job with this engine. I agree, a higher limit would be nice but...are you planning an extensive valvetrain rebuild first?

umm sure if you say so ... i know that ive had many people into their laptops and tune their cars via that on stock ecu ... and not have any reprocutions of raising the rev limiter, boost, adjusting the air/fuel etc. ......

...also, if you're really going to do it, where will the ecu get the fuel map from for the last 800 or so rpm? I agree, it can easily be done, I just can't afford to replace any valves and seats, so I won't do it.

hurley i dont think its possible for a piggyback system. only way would be actually reprogramming the ROM of the computer
piggybacks tell the computer false information ie: want your car to run rich... the piggyback tells your computer your funning lean thus it putting more fuel in. vtec is a selenoid relay that activates. meaning all the processes are still being done by the computer.

I don't think it would help to raise the rev limiter. I have quite a few mods on my car that help it breathe better. But even with all of the mods the dyno still shows it peaking in HP at 6300 to 6700, and then falling after that.
It doesn't help to run the engine at higher RPMs if you're getting less horsepower in return. Besides - the internals weren't designed to go that fast.

its just my gut instinct that the car has another 700 or 800 rpm in it left .. i mean it can hit 7150 easily in second gear .... just wants to keep moving in all gears.

would you not be able to mod the air/fuel ratios on the unichip?

GReddy E-manage stand alone engine management system. Get a copy of the base map from scalbert over at a-cl.com and then work from there. That should be a fully programmable ECU. And be optimistic, if doing this causes bent valves, its an excuse for someone to get off their ass and create a new titanium valve train! That way a disaster turns into innovation! Good luck with everything.

our engines can handle more rpm with out damaging valves and other components, i have no doubt in that. (from past experiance with other hondas) but the problem come from it just not making more hp at those rpm's with out major remapping of fuel,air,spark ect.. that and needing different cams to take advantage of the rpm increase. if some one would start making different cams for our cars it would be a nice way to get more power and rpm. as for reprogramming the ecu, it cant be done. you will need some type of stand alone computer to manage all that. if hondata would make something for a v6 like they do for the 4bangers then alot of stuff would be possible
