A friend in DFW is doing a J32A2 swap into an S2000 and need a hi res pic of the ECU off a 6 speed.
Here is his request.

I will need pictures good enough to read the component values for all components on the main circuit board.

This will be an awesome Frankenstein when done. The athleticism of the S2K witht he heart of a 2nd gen.

why doesnt he just buy an ecu? he is going to need it

pmptx

I think he is looking at how to pinout connections.
Otherwise, dunno, he may have something else up his sleeve.
The guy is a Honda guru kinda like Kris.

is that what you wanted?

pmptx

I will push him the link and see if it works, if not, can I have him contact you?

Hi, I'm the friend pmptx mentioned...

I'm looking for a shot of the inside of the ECU, the circuit board. Good enough to read the silkscreened component references (R101, R202, etc.).

I'm trying to avoid buying a 2003 CL-S ECU, they are >$700 new and I can't find any used. I also haven't gotten a response out of richieV6 and his supposed black box that I've been hearing about to convert auto PCMs to manual ECUs.

I'm trying to identify the internal differences to see if an auto PCM can be converted to a manual ECU internally. This is usually possible on the 4-cyl Hondas so I am thinking it will be on the J series as well.

assclown, could I possibly get you to open it and take a pic or two of the circuit board? I'm looking to ge a shot (or multiples) covering the whole board, high enough res to read components. I'll be glad to share whatever info I find out.

Thanks!

For anyone that's interested...

Good luck marcucci. Can't wait to see this Frankenstein come alive

marcucci

Thanks, I appreciate it. I'll get a lot closer once I find an off-the-shelf ECU to use!

If anyone is wondering... I am trying to make the car smog-legal, which means that since it's an S2000 (2000-2009), in most areas it needs to have a working OBD2 port. That means I am stuck with a stock (ish) ECU.

From what i have read the Auto eprom cant be reflashed, the manual can. Richies modules dont convert it to a manual ecu, they just trick the ecu into thinking things are working properly

i'm not sure if its a 6 speed but he can answer all the questions you have

Kris,
Marcucci does to S2000's the same type magic you do to our 2nd gens.

Now that I have both is is awesome to see them coming together in this way.

BTW, not my car he is working on, although one day

marcucci

fsttyms1, I understand that Richie's box only tricks the ECU. AFAIK all Honda ECUs 96-04 or 05 (depending on model) use OTP processors w/o external rom and are not flashable. By 04/05 all processors went to a flashable design.

But right now I just need an ECU that-
1. has a viable OBD2 link
2. will set the ready flags and not puke auto trans or other codes

If I can swap some resistors out on the ECU board to "change" it to a MT from AT ECU, I'd like to try that.

If it's programmable, I can handle that, too, but I have to SEE one of these things on the inside first. I can't even find one to do that.

DC3328, thanks for that link- I will try and contact him. This is the sort of info I am looking for, but it looks like he is doing it to an auto ECU... not sure if he will share that info.

I'd still like to get that pic if anyone w/a 6MT is willing to help!!!

To sweeten the deal, I'll pay anyone who can get me a usable pic $50 via PayPal.

fsttyms1

This> than all!! If this comes together it will be awesome.

ehhhhh. i don't feel comfortable breaking it apart, i believe it's got a tamper tape seal on it and i bought it used for my 6 speed swap, and i'm just gonna end up using a TL-S ECU instead. i can sell it to you for $375 shipped if you'd like.

I paid $450 i believe and i never used it (still collecting parts right now) it's been sitting in an ESD bag since i got it.

either way, i can't wait to see this S3500 come to life!

marcucci

assclown, I am interested. I think I'm too new to PM here. Please email me at todd at marcuccimotorsports. com

Thanks!

marcucci

Oh, and I've PM'd that guy Don to see if I can start a discussion on ECU conversions, since he apparently knows more than anyone else on the planet about these.

i have a 6 speed ecu for sale

note: the 03 ecu for the cl had a flashable eeprom. they switched to one time eeproms after that and before that. only the 03cl has it

looked at your blog. i would use a 2nd generation cl engine and use ody internals. this gives u the freedom of drive by cable and no DBW bullshit.

also has open heads for replaceable headers. no dealing with BS cats on the manifold.

the immobilizer can be removed from the cl-s ecu and the car will run fine.

guages are hardwires and no CAN cable is needed. its a simple resistance setup.

not to mention the 2nd gen heads are the free-est flowing. its been proven. a j35 build on a 2g block can push 290+ hp. good thing is the blocks are all identical so u can just swap the heads onto your current engine and use a 2g manifold (also replaceable with the 4g manifold that yeild 10hp down the powerband)

paul also makes an 80mm manifold for the car

marcucci

All I can say is that when I looked at it, the DBW only adds some minor wiring/relays and the DBW controller, and the cats can be deleted (I have to do custom headers anyhow) and the integrated manifold doesn't look too ugly. For what it's worth, the 04 TL base under the same/old HP/TQ rating did slightly better than the 03, albeit with higher compression.

How? In my experience it's integrated to the ECU and can't be "removed", though you can copy codes into keys and/or program new ones in. I saw the j32a2.com posts but didn't see any real discussion on how to do it.

That is something I was not looking forward to.

I'm interested to try a J35A8 or see an actual dyno b/c I would guess the numbers are higher than they advertise. The valve sizes are the same on some of the newer J35's and J37's, and I'm sure the castings are improved, but that doesn't mean they flow better.

At this point I'm not looking to build, it's not in the budget. The first one I do will be a simple swap. I'll play with an actual build later on my car (this one is for a customer).

I've noticed that the VCM motors and some others come w/piston sprayers. I also have read but haven't seen any real confirmation that some of the J's don't have forged cranks (which I thought all Hondas had).

Help me out, I'm a J forum novice- who's paul?

Thanks...

phee

iTrader: (5)

paul is nva-av6 on this forum. some blocks do have piston sprayers and im speaking on the 01-06 j series motors.

i picke dup my j32a2 for 360 bucks. that leaves a lot of room to build considering your budget seems like 1500 for an engine.

the 2nd generation guages are the ones i was referring to earlier.

some of the oddy cranks are not forged and some of the other j's arent forged. im not sure if the j32a2 is forged or not. doesnt matter if youre not going high boost.

we can run about 8-9 psi with a good tune on stock internals. this yeilds about 475hp using a gt35. (turbo size matters) --strictly speaking about a j32 from the 3g tl.

the higher comp of the 3.5-3.7 lowered the ability to boost unless u use the j37 block.

i think he is talking about P2R. they make an adapter for the 09 SH-AWD IM for the 2nd gen's j32

phee

iTrader: (5)

no. im talking about pauls 80mm throttle body and honed out manifold

marcucci

I'm not really willing to tear down a motor w/o a proper hone/clearance, and even on the cheaper motors this could run several hundred to $1k in parts and labor. I could half-ass it but I don't want to put a car on the road for someone that isn't going to last as least as long as it would have before I touched it. So building isn't really cheaper for me.

FWIW I picked up a 45k mi J35A8 for $1400 shipped. I can find the early J35's and J32A2's for <$500 all day long in good shape in the D/FW area. I was very specifically looking for the J35A8 to try and get as much power out of it and still use a 6MT ECU. I couldn't find any J32A2 6MT ECUs anywhere until I found this forum.

I'm very interested in doing it, though, I think there is a lot of potential in the J's that most traditional "Honda" people that play with the 4's are ignoring. Cost is going to keep coming down on the motors, too, w/Honda making hundreds of thousands of them a year now.

Does anyone here know about the compatibility of the 01-03 AT, MT, and 04+ cam/crank sensors? I'm curious which sensors work w/what ECUs and what types they are.

shipped. fyi

Thanks, appreciate it!

and your item is shipped too good sir

can't wait to see a j powered s3500

i forgot to mention i have a j32a1 (54k) if you or any of your guys need one
