Any thoughts? I am gong to start gathering parts for the 3.5 swap. Wondering about the VSC, the TL-P doesn't have it, what do you guys think will happen? Any thoughts are welcome.

dands99tl

Well, it's on it's way, got it for $10 shipped, guess I'll just have to wait and see what happens. I will post my findings after I try it out. I figured with as cheap as it was, couldn't go wrong. If it doesn't even work I won't really care a whole lot.

YO you gotta be carefull dude, the TLS ECU has a LOT of differences over the TLP... There are serious differences in fuel curves, ignition and TCS will probably flip out...

you should NOT swap them unless you have a diag computer to monitor everything going on... No one has ever tried this....

dands99tl

I do have access to an OBD2 diag computer, so I will just simply plug it in without starting it to see what happens. I know there are major differences, but I plan on upgrading the engine, so I since the ECU so was so cheap, I figured I would start there. Do you know the differences in the TCS vs. VSC? Does VSC control the brakes and throttle?

etxxz

you got some balls broda!!

while you are at it, you might wanna think about the manual trans swap you wanted, if you do them both at the same time it will be more economic...of yourse, you'll still have to drop en extra 2Gs for the tranny...instead of 4-5.

ill check on you later.

TCS employs only wheel braking up to about 20MPH. VSA is a full-time traction system employing not only wheel braking, but engine throttling as well.

Get ready for a fried ECU!

Why would you say that?

I am looking at a similar issue. I want to swap a TL-S CPU into a 00' TL. Bad idea eh? What do you think the overall result will be? Shouldn't i see some power and torque improvements? IDeas...

Why not just look for a TL-S engine and swap it. Getting TL-S parts here and there would likely give you minimal performance gains and maximum headache gains. I'm sure someone has totalled theirs leaving the engine/ tranny still intact. With swapped parts like these, even if you got them to work, prepare yourself for a voided powertrain warranty.

dands99tl

My car is WAY out of warranty, so I'm not concerned about that. I just got the ecu because I plan on doing a swap, so when I do, I will already have it. My plan is to do a 3.5 swap with various Type S parts in the mix. I should have my ECU friday, so this weekend I will try it if I have time.

A dands99tl good luck man

If you need some help Pm Austin519's or here
Austin519's HP
He as done the swap on his 02 TLs.

One difference beween the TL-S and TL-P is the TL-S has the 2-stage intake manifold. I assume it's ECU controlled so there might be an issue putting the TL-S computer on a TL-P with respect to that. I don't know if the 3.5RL has the 2-stage intake or not so I wouldn't know the compatibility there. Just something else to think about...

dands99tl

Well, FINALLY had time to try the ECU yesterday. No dice. Removed the stock ('99 TL-P) ecu and compared it to the '02 TL-S ecu. Noticed that the main plugs are all the same between the 2, BUT on the other side of the ecu is single small plug. The plug on my TL-P was smaller than the one on the TL-S. I think this is the side that controls the TCS, but not sure exactly. I thought I would try it anyway. Plugged in the 4 plugs on main side. Turned the car to the on position, D4 flashing, TCS light on, CEL on. Will crank but not start. OH well, it was worth a shot. I will get a picture posted of the 2 ECUs next to each other so everyone can see what I am talking about. Anyone have any use for an '02 TL-S ECU?

Looks like you're gonna need a new wiring harness. Then you need to figure out what all the pins do, where they go, etc etc.

I don't know that I would wanna be around the first time you start up your TLP with an TypeS ECU.

dands99tl

Yeah, I'm not gonna bother pursueing putting the TL-S ecu in. I think the TL-P ecu will probably run the 3.5 swap just fine with the aid of a VAFC. I got such a deal on the TL-S ecu I thought I would go ahead and give it a shot.

The other thing I'm not sure of is if the difference in the plugs is a '99 vs '00-03 thing or if it is a TL-P vs a TL-S thing. Whatever it is, it makes a difference as the TL-S ECU would not even start my car at all.

If anyone wants this TL-S ecu for a UNICHIP core let me know.

fla-tls

Where did you get a TL-S ECU for $10???

dands99tl

I bought it on ebay, guy had tons of them. I figured for as cheap as it was I wouldn't really care if it didn't work.

hzm82

Acura has a design ECU to go along with the trans swap. Those are probably the org ECU that you got off ebay.

fla-tls

That's true, the 99 is a 4 speed. Perhaps that larger plug on the TL-S ECU is for the transmission.

fsttyms1

the big reason you would really want to get teh ecu to work is if you do the 3.5 conversion with the type s intake and cams, you are going to need the type s ecu to tell it when to get the 2nd stage actuator to work and MOST importantly so that the redline is raised. other wise the type s intake and cams wont be used to the full potential. i would start doing some research on what pins are different and get the wires swapped to match the correct spots

dands99tl

DUH! Besides the lights that where on, I just thought of something. Not sure why I didn't remember this. The ECU is made to work with a certian key right? Our keys are "chipped" so that you can't just break the ignition and twist the start mechanism like you can on older hondas. Even if I get around that issue, I still have all the rest to deal with.

Does anyone out there that has '00+ TL-P have a picture of their ECU that they would like to share with me? I'm trying to figure out if the plug difference is year specific or model specific.
