Greddy does the same thing with there turbo kit on an civic SI

[Apox]

For the oil return, greddy provides a bolt to replace the oil drain plug...

[Apox]

In my search for the ECU wiring i found this list. Just have to take a good look at the car and compare it with the list.
With this i can wire the greddy in no time...

[EP_Marv]

mate ive got an EP1 ....

u go for it !!! EP1! FTW !!!

[civicboy]

top man, for doing something different

[Apox]

I don't know the name in english; but it shuts the turbo off so you can configure the pressure. I have a few other models if this isn't a good one for this project...

[coco-loco17]

good wiring information, i'm sure i will use this for my emanage set up, thank you

This is good news as this is a step forward to connecting the emanage!

[coco-loco17]

good pics mate, they'll come in handy, i just need a wiring diagram for emanage telling me which wire is which on the greddy unit

[neslug]

And some more wiringschemes














Hey coco-loco, I don't have VTEC, but I think Apox might be able to help u with this using these schemes. It's like reading Latin for us, but babies fairy tale for him ...

[coco-loco17]

are those diagrams for emanage? (there too small on my work pc )

also i don't think emanage deals with vtec as you can use it on other cars without variable valve timing

[neslug]

Those schemes above are honda workshop manual schemes, these below are even more interesting

This is the closest I can get, the wiring of an S2000. Good news is, half of the connections seem the same as EP1/EP2. Bad news is, some are different.... Apox will find a way for sure, and the vtec connections seems easy too



This would be my translation of this scheme from S2000 to EP1/EP2:

TPS signal: connector A15-red/blk-Throttle position sensor
VTM: ??? possibly S2000 specific differential/oil pressure signal (I really don't know)
IGP1: connector E9 -yel/blk-Ignition input signal
PG1: connector A:
4-blk-Power ground
5-blk-Power ground
RPM/NEP: connector E26-blu-Engine speed pulse

And specially for coco-loco=>
connector B15-grn/yel-VTEC Solenoid valve
emanage sure DOES deal with VTEC, allows u to modify your VTEC kick in point





Good news for this one! Same for S2000/EP1/EP2, tnx to Honda for making this easy
Don't know for the grounding:
PG1: connector A:
4-blk-Power ground
5-blk-Power ground
probably one of these...






I leave this one to Apox, as I have no clue what's this one about!

Probably connector A:
27-brn-Igniton coil 4
28-wht/blu-coil 3
29-blu/red-coil 2
30-yel/grn-coil 1


Phew.... this one took me a while to figuere out Enough wires for today!

[coco-loco17]

good work, im very impressed! hopefully my mechanic will make sense of it

[neslug]

good work, im very impressed! hopefully my mechanic will make sense of it

Even I can make sense out of it, and I'm nowhere near a mechanic's skills My guess is, it's noobproof, only we are screwed since it's not intentionally made for EP1/2

[coco-loco17]

yeah if we wire it wrong engine goes boom
