Jst picked up a 05 cluster in red for 34 bucks of ebay . ive wiried lots of clusters before but i hear there is some mods that need to be done to make the temp gauge working. any one have any insight as to the mod needed.

Thanks and i will post pics soon as i find harness plugs for it lol.

oh and a little teaser

Still working out alot of bugs.

Full write up to be done when wrinkels are ironed out.

 

sex! lol

i've thought about doing the 03-05 cluster swap also, but elected not to since i have yet to find any hard info on how to make the temp gauge work properly. its not quite as complex as the s2000 cluster, but i imagine that it doesn't just accept the standard analog 0-5v signal either.

 

yea i saw that vid. there is one other one on there and he states he has the temp gauge working . Didnt get in to to much detail on how he did it but i did message him about it.

he stated he had to do some re soldering on the cluster board. I wonder if any one on the 01-05 board would know what the the temp sensor impedance or voltage is.

My speedo is shot in my ek so why spend 100 on another ugly ek cluster lol. could pass it up for the price.

 

my ek's speedo is also on the fritz! lol. i would like to do a swap like this but i feel like i'm just going to have to settle for another ek cluster or maybe one from a crv. and of course trying to find a 5spd crv cluster is damn near impossible also.

 

oh helllllllllllls naw im jealous as hell... i tried doing the conversion to my eg and the cluster got fried... HOW DID YOU CONNECT THE POWER CABLES for the cluster???? please the information is greatly needed since i bought another cluster because i really want the cluster swap into my eg and it didnt fit with the eg dash so i put in a gsr dash which it looks just as nice as the ek dash with that cluster...

 

here's some info on the coolant temp gauge on the 03-05 cluster. it's not looking promising however :/

"Engine Coolant Temperature Gauge

The engine coolant temperature gauge is controlled by the CPU built-in the gauge assembly. The CPU receives coolant temperature information from the ECM/PCM via the multiplex control unit, The ECM/PCM receives coolant temperature information from the ECT sensor."

so it sounds like it works similarly to an s2000 or rsx cluster.

found this also. after reading through a bit of it i think it's clear why no one has come up with a simple solution to the problem at hand.

the only time i've seen someone with a functioning temp gauge on a newer cluster is when it was also used in conjunction with the newer ecu and multiplexer unit.

 

the only other option i see being remotely plausible is installing the guts of a standard analog temp gauge into the newer cluster. no idea how hard or easy that might be, just speculating at this point.

 

yeah d16 is right i looked into the temp gauge thing and it will only work if you get the fuse box from that car because the multiplex is INSIDE OF THE FUSEBOX.. thats some weird stuff honda is busting out on the newer cars..

 

i cant see why the temp gauge would not be a normal gauge after this multiplex crap.
I will know when i get my hands on it.

temp gauges are pretty simple +,- and a signal from a thermp resister. i need to find out what the 05 thermo resistor reads (ie 0 to 1 ohm ect) if they are the same i will need to bypass somthing in the cluster to simplify it back to a standard 3 wire set up.

I will update when i recive the cluster. in the meantime any other tips would be great.

Thanks

 

opps

 

in my mind without looking at the guts. the gauge has tp be a standard electroinc gauge that needs power and ground and a signal. i am hoping that once i bypass what evee is in the cluster i can go directly from the ek temp guage plug right to the 05 cluster . mabye im thinking to simple lol.

 

correct ^

that's the problem, its not a normal gauge even after the multiplexer. think about it. quoting what i posted above from ALLDATA, "The engine coolant temperature gauge is controlled by the CPU built-in the gauge assembly". which means the gauge has to actually decypher the signal from the multiplexer. there's no way the gauge on its own can interpret an analog 0-5v input.

if you read in that other link i posted above you'll also notice mention of a startup signal that precedes the data relevant to the temperature. because of this i'm thinking it will be extremely difficult to replicate such a signal.

 

i see what you're saying, but unfortunately i don't see it being that simple. by all means though tear apart your cluster and see if you find anything interesting. if you find a way to make it work though, i'd definitely be alright with that lol

 

I see what what your saying. Ihate when thinkgs dont work the way they are supposed to lol. I am dl'ing a service manual now. curious to see what it says.

I hope the guy from youtube gets back to me, it may be a hoax vid but he says he bypassed somthin on the cluster board........hope hes not full of it.

 

very neat. I did the dc2 integra cluster into my 96 ek hatch. Was a pain in the *** repining and what not but turned out awesome. Good luck!

 

i hope so to. maybe it is that simple..

of course if it was legit why has he not already shared this wonderful information lol

 

well heres why i call B.S on his vid.

The vid you posted is clearly in a ek. the cluster doesnt "beep"
the other vid the dash/ car is not posted. and the cluster beeps when starting. makes me think its in the orig car or he has the multiplex stuff working.

 

^good point. i'm not sure what to make of that

 

found it! this is what they use to make the ect work on the s2000 cluster swaps. looks like it can also be used on other clusters.. like civic ones perhaps

http://www.modifry.com/products/ect/proghelp.htm

not exactly plug and play right off the bat.. but looks like this should do the trick though. i might have to look into getting this now lol

 

the diagram i found shows there is a drive circut that controls the needle sweep. so im sure theat my bypass idea is shot . but i stil want to find out what the 01-05 ect sensor range at for signal.

thanks for the link, some good reading in there

 

the ect sensor on the 01-05 is a standard 2 wire 0-5 volt sensor. just need to find out what signal comes out of the multiplex unit.....

I am goign to take some impedance readings on my ek ect (cold and warm)and see if it specs up to the 01-05 civic. ....hope this thing gets here soon so i can get started. still need to find plugs though........thas not going to be to fun

 

i dont mean to thread jack you guys but does anyone atleast have a random pic with the swap done, i cant quite remember what the em2 cluster for the coupes look like

 

i think the best you're gonna get is the video i posted above. i can't find a single thread anywhere on this particular swap

 

i don't know if this would help but here you go: (not specific to your temp question though)

https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/2004-civic-cluster-ek-2720309/

I'm interested to know if this would work. good luck to the OP.

 

thanks. i did read that. no mention of temp gauge. but the site thats from is somwhat local to me . so thats a plus
