Check this out...

Been doing some research and I noticed something interesting... For those of you that are looking to do, in the middle of doing, or have already done the 6MT swap, check this out:
So, here I am on car-part.com looking for 6MT motors; for the Acura TL, TL-S, and CL-S. BUT... I noticed, for the Accord V6's, there's really no options when you're looking for the type of engine(AT or MT) ... you're either just stuck choosing between the 2.4 or the 3.0.

Now, my question to you is... Theoretically, if there is no difference between the the J30's sensors/timing components that come in both the automatics or manuals, wouldn't the 6-speed ecu from the J30 work with a J32 if wired up correctly? Granted, you'd have a lower vtec engagement point and lower redline, that'd all be easily fixed through tuning. What do you guys think?

 

eh, richie's module has some sort of sensor connectors for the j30s and no connectors for the j32. Seeing as how the tranny sensors are being tapped into by richiev6, there has to be a difference between mt and at ecus.

 

it will work with a lot of wire splicing. and the redline cannot be raised no matter what kind of piggy back you have. if ur gunna go through all that trouble then why not just re-wire your current ecu?

 

I looked into that as well, I've watched my friend mess around with his emanage blue for his accord a while back and the rev limit can be raised. As for the re-wiring, I can make an adapter harness, no biggie.

^ I'm not talking about the ecus, I'm looking for any differences between the J30's automatic and manual engines. If there's no difference, I should be able to just use the J30A1 6MT ecu with any J32 engine. Makes sense? Think about it... The J30A 6MT harness is only $247 new from honda, the J30a 6MT ecu's only $50-$150 used from any junkyard, plus the re-key from honda's only $25-$69 depending on where you're located (I called around and asked)... Its looking way cheaper than anything I've seen on these forums.

Also, the '03 6mt's can control the IMRC of the J32a2 as well (I double checked in alldata and helms) to make sure. The only annoyance I see will be tuning which can be fixed.

... Just throwing ideas out there.

 

umm, what are you trying to accomplish? Are you trying to do a 6mt and motor swap?

Why go 2.4 or 3.0?

 

I've already done a 6MT swap, that's not my issue, I'm looking into doing one for a friend. The thing this, i discovered this while I've been searching around for parts. It's currently a J30a1 w/ the 4 speed automatic transmission. But since he's already got an e-manage ultimate, it'd be cheaper just using the j30a 6mt ecu mated with the J32a2 engine using the J30a1 6MT harness. The rev limit, and vtec engagement points, and IMRC won't be an issue and all of the connectors match everything on the j32 with the exception of the vsa connectors. I'm not worried about those either... see where i'm getting at here?

I'll compare the two:

J32a2 6MT ecu + a2 6-speed harness = $500+

J30a1 6MT ecu + a1 6-speed harness = $300-$400 (or even less).

So far, the total cost of the entire 6-speed swap's hasn't passed the $900 mark yet since we got lucky finding everything from a wrecked accord.

 

Now I see where your coming from.

You want to use a j30 6MT ecu/trans with an auto j30 engine.

I don't think anyone can solidly answer your question.

 

go to v 6 p . n e t

they can help you out a lot more when it comes to accords and they do a lot of j32 swaps

 

Now we're clear on my objective. My theory is that it should work since everyone lists the J30's automatic and manual engines in the same category.. mind you, I could be wrong. BUT, from what I've observed, the honda ecu wouldn't give two shits about what motor/sensors it's hooked up to unlike Acura's ecu which throws a bitch fit. A while back, I read up on the '04 accord ecus. You were able to use either the auto or manual engines with the same ecu with no variations at all. If this is the case, the j32 should work.

 

Normally, I would... but just posting on there's ridiculous. No offense. I'd rather create some buzz here since I've been here longer than over there.

 

non taken i'll take azine any day of the week, i just thought they'd be more knowledgeable about your situation

 

Knowledgable? Yes. Ignorant? Very. lol... so me making a question/informational thread there defeats the whole purpose since either it'll get criticized, flamed, deleted, etc. ... you know how forums go...

 

I'll continue posting info about this setup soon once parts come in. There's a few dudes on here that were asking me questions, so I'l have to come through with answers. lol

 

I would like to state that when searching for a j32 engine on car-parts. It doesn't list MT or AT just base or type S. However, as we all know... we can't use a cls 6mt ecu with a j32auto.

 

See I thought you were talking acuras.

Proof of said raised redlines? I've only seen i4's with higher r/L.

 

It does if u specify 03cl it asks mt/at/s/p

 

Sorry for not being clear if I wasn't. If you search, there's a whole bunch of people that have been able to raise their red lines in both i4's and v6's. Good example: the 240sx's, MKIV supras, civics, tc's, accords, and a few guys with J swaps over on v 6 p that are running boosted with the emanage blue and ultimate with the J30 and j32 ecu's. If you go to the emanage forums, I've seen DIY's where modding the emanage blue to the gold version unlocks everything the ultimate already does for only half the price. I'll be doing the Emanage blue to gold mod soon too once I'm ready.

I'd rather pay $150-$300 for a used emanage blue and just take the extra 15 mins out of my time to convert it to gold rather than spending the $500+ for the ultimate. I didn't realize it was that easy.

Sounds like you're looking for just the engine for the 2nd gen TL/CL..... Listen. When you search for the '03 CL-S engine, it'll ask you if you want the auto or manual engine.

Now... here's the eyebrow raiser... When you search for the motor for the '03 Accord EX V6 6-speed it doesn't give you the option of picking a manual or auto.. it just gives you... just one option.. the 3.0 V6. Mind you, if you look very carefully, as listed, from '03-'05, you have the option to pick either motor from an auto, or manual EX V6. What that tells me is the following..... The J30 ECU doesn't discriminate between the sensors/timing components of the automatic and/or manual J30a1.

With that being said, I've seen J32a1's, and a2's being controlled by auto j30 ecus with the 4 speed transmission.... logically, you'd still be able to use the J30 manual ECU with any J series motor no matter if it's an auto or not... make sense?

... Now, if this is the case, and this infact DOES work where you still get vtec, speedo, etc..... with the cheap piggy back, and wiring harness of the J30 or j32 (either way, you still have to do some repinning for the immobilizer unit wiring, IMRC, and 1-2 sensors), it'll be ALOT cheaper than going the full J32a2 6MT ecu, wiring harness, getting the timing components, blah blah blah.. get it?

 

Alright, I just looked over the differences between the J32a1/a2 and J30a1 ecu pins. This is going to be a piece of cake.

I got this. Let the conversion begin!!

 

doh I forgot that the TL doesn't come in 6mt cause I have the swap done lol.

 

 

bump.

 

all those non-hondas may have rasied redlines. but the hondas with v6's havent showed a raised redline. just because they are running emanage doesnt mean they have raised the redlines. that function doesnt work with our ECU's.

oh..i have searched. plenty of times. feel free to prve me wrong and show me a v6 honda accord/civic with a raised redline.

afaik only hondata has been able to raise the redlines--and tht was with the i4's

 

 

Any answers to my question about the J30 6MT ecu? Don't really care about the lowered redline, I'm curious to know if it'll work.
