Type S ECU
Has anyone ever tried switching the ECU to a Type-S ECU? I have a friend who works for Acura as technician. Today he told he he switched out the ECU on an Acura TL for a Type-S ECU. He was just experimenting & noticed that the car had better performance & pulled much better. JW if this has ever been done?

im gonna say wait for ihc, inaccurate, opel, bymer or NVA-av6 to answer this. for stroker motors like mine i would love to know if this is possible.

Hi speed

Sounds like BS to me. The engines are not the same displacement.

first ask him how he comes to this assumption, then firmly smack him in the forehead... kthnxbye

You would think if this were possible, people like Paul, Rodney, bmeyer, etc would have done this already instead of going with a piggyback.

I'd say your "acura tech" is full of shit.

Opel

was this his own car or a customer's? just experimenting? really?
i can only picture some tech doing an oil change on a customer's car and just decides to swap ECMs and REPROGRAM keys and take the car for a drive "EXPERIMENTING" ............come on man, give me a break..

you know what i think it is? I think this friend of urs is just an invented friend...
I think its you wondering if it would work, but were too afraid to ask through a thread, and be smashed down with no mercy lol

I'm not sure if 3.2 engine harness is same as 3.5 engine. If they are same, I dont see a problem swapping ECU's. TL-S ecu would offer more fuel and timing due to bigger engine.

04 TL ECU dont match 06 TL so probably dont match TL's ECU. Your friend is BSing

Yeah It was my friend, & yeah he works for acura as a techican. & maybe your the dumbass whose car he did that to, just FYI- we took your sunglasses also. Im here to ask a serious question, if your gonna be a moron, then you can just shut the hell up. I thought this was a serious thread, just wanted to share shit with acura members with a serious question. JW if this was ever heard of, its just like switching ECUs on a GSR for a Type-R. What great way to experiment on mods with an idiot like Opel who takes his car to the dealership!

If thats true then your a douche bag. Please crash your car into a wall.

Take a DEEP breathe.

Your friend is a technician at a Acura dealership.

You already know he is a dumbass.

04accordcpe

iTrader: (3)

first off, its not like swapping a gsr ecu, to a type r, because they are the same dissplacement einstein

second, if your acura technician friend has confirmed and supposedly done this already (unless imaginary like opel stated), then why even start a thread? just do it

lastly, where does it say anywhere, that opel stated he takes his car to the dealership?? are you reading imaginary post's too??

PowerCommander

Tell your imaginary friend there that he should have came up with all error messages and check engine light if that was possible. He better take that imaginary car back to the imaginary stealership. It does not work period.

I hate cars

Of all the people on this board, you pick Opel to call a dumbass and say he takes his car to the dealer.

IF it is possible, it would require a complete swap of the engine wiring harness (and most likely various engine sensors) for 04-05 cars at a bare minimum.

Even then, the tune is going to be WAY off. The cams have a different profile and are going to throw the A/F way off. Anyone know if the Type-S injectors are different? I would assume they are, which makes this even more hoaky.

I'm with everyone else though. I'm calling BS on this. There are 0 details in this thread that would convince me otherwise. If the so-called tech did this already, then WTF is the point in making a thread asking if anyone else has done this and what the thoughts on it are? Tell HIM to do it, put it on a dyno and then put up a how-to if there are any appreciable results.

I hate cars

I wasn't going to comment seriously but I'm bored.

From a purely engine management standpoint it can definately work.

The 3.5 is a small jump up in displacement and airflow over the 3.2. So small that the 02s could *almost* compensate given some time.

Not sure if Acura added larger injectors with about the same pulsewidth or used the same injectors with a higher pulsewidth for the TL-S. For all I know the TL-S could run the same injectors and pulsewidth and run 10psi higher fuel pressure to make up the difference.

When I went from a 3.8L to a 4.2L I was worried but I was told add 10% more fuel to every aspect; idle, cruise, PE, and WOT and I would be fine. Sure enough it really is that simple. Adding displacement with a similar to stock powerband is very easy to predict the VE tables. You can add fuel at a flat rate and it should be fine. The 02s can fine tune it.

As for making more power with the TL-S ECU, not sure how that would be possible assumiung the base ECU keeps the 3.2 on the verge of pinging with as much timing as possible and the AF is kept constant with the widebands.

If anything I would expect less ignition timing from the TL-S with it's longer stroke.

The ECU can only add power in one of two ways.... More timing or more/less fuel. The end.

It's all really speculation as to the differences at this point.

What's not speculation is the insane amount of adapting and wiring and the amount of headaches involved along with all the other systems that use the ECU that may or may not work with the swap.

On this topic, does anyone have the specs of the base vs. Type-S cams?

And just FYI, the injector part numbers are:
16450-RJA-A01 - '07 -Type-S
16450-RCA-A01 - '05 - Sport (6-MT)

I couldn't find any specs on the displacement of the injectors. I believe the '05 injectors are 270cc, right?

You are all wasting your time. I smell troll......

bmeyer

iTrader: (3)

Meh. There are TONS of troll threads that are a complete waste of time, but the bright side is that there are some valid questions that some from individuals other than the OP that either reiterate or expose other valid information for the community. Had I said "F(*&^% this troll." every time one posted, I'd have left years ago. Hell, I still teeter on the thought, but it's the valid information that keeps me coming back.

OP, have your friend swap out ECUs and come back and tell us what you think. If he was able to do this so quickly while at work, he should be able to do this to your car with no problem

Bayam0n

the real question is, was you friend testing this out on the 3G type-s? or the 2G type-s?
maybe it might work with 2g type-s to 2g TL, but I don't think it would work with the 3G

i wanted to test my ECU when i was having problems one day. Looking at the wiring diagrams and connectors compared to 04-05, theres an extra plug i believe and pinout diagrams are completely off. signals where negatives are and vice versa. compared to a type-S, i can assure he did not just swap out ECU's like if it was plug and play.

And to bmeyer- "Even then, the tune is going to be WAY off. The cams have a different profile and are going to throw the A/F way off. Anyone know if the Type-S injectors are different? I would assume they are, which makes this even more hoaky."

there have been people with type S cams in the base TL obviously not able to tune the base TL and i haven't heard it causing problems...

bmeyer

iTrader: (3)

@InFaMouSLink

Right, but his 'buddy' is attempting to go the other way. With Type-S cams in a base engine, you're adding more air into the system and effectively leaning out the mixture. With a Type-S ECU in a base model, it's going to enrich an already slightly rich mixture and take away from the car's performance.

The claim that he was able to, presumably, take a customer/dealership's car, drop a different ECU in and *feel* the gains doesn't add up at all.

Opel

I give all you guys credit for taking the time and effort, to explain all this...I sure as hell had no motivation to do so, and this is why: Even at this point after all the input you guys provided, I have high doubts that the OP is anywhere near convinced.

OP, since your "friend" tried this and it worked with positive results, how come your thread states questions rather than "Hey guys, this is what you need to do, this works etc"

And btw, I'm sorry I exposed you the way I did...hope I didn't rub you the wrong way, despite the name calling and all that, I'm still cool

worldon1finger

Ok we can not put the tl-s ecu into a regular tl car unless it is manual. The auto tl-s has VCM where as the auto tl does not. I do not see any benefit from doing this even if you are manual. I have the tl ecu in my accord and I love it but I did it to help with my air fuel ratio out since I have a J33 build. It definately helped me from adding much more fuel with my fic and keeps it more steady.

tenzingsherpa

^^ i was wondering when u were going to reply. lol.

so brett u definately sure the manual tl-s ecu can work on manual base tl?

although i wanna say its not possible, im really not knowledgable when it comes to ecu swapping, tuning etc. i would like to know the pros and cons of using a tl-s ecu.

worldon1finger

According to Paul if I remember correctly that the manual tl and tl-s ecu's could be swapped but the auto tl-s has VCM so it can't be swapped. I would just tripple check with Paul if your looking at getting an ecu for your car. I must say with the tl ecu the car runs much better than with the accord ecu.

Isn't the TL-S ecu Denso while the regular TL is motorola? Huge difference there......

iTrader: (4)

since when did the tl-s come with vcm?

Dan1629

I thought it was called vsa but anyway, Don't think your friend did anything of the sort. doesn't seem probable on many levels. Yea his service manager let him screw around with ecu's on a customers car. yea ok! yea yea thats it, thats the ticket.
