Well a stand alone is probably easier and the best way in my experience in the long run.

[Emperor]

i totaly agree

-the whole harness is much simpler
-NO MORE MAF
-I can add whatever (boost control,shiftlight etc)
-I can run a Map for german fuel (jap juice have much more octane-->expensive sh** here)
and and and

i was always a fan from Megasquirt (LOL) and now i bought one and i will see if it fit me


if not i convert to a Honda ECU^^ that stuff i know very well

[Draconis]

How you going to convert to a Honda ECU to control the rb20? That I havent heard of before.

How you going to convert to a Honda ECU to control the rb20? That I havent heard of before.

was more a joke, but its possibel

many 4age owners convert theyre cars to a honda P28 or p30 Ecu, since you get with a chip kit, an emulator and chrome already a full standalone for a couple of bucks

a d17 ecu with the gay hondata motherboard would do the trick on a RB too

[Emperor]

ok pals

radiator is ordered:thumbsup_anim: Mercedes 190 w201
and i start to strip down the harness, what a bloody mess but i can sort out stuff like CAS and MAF

no the interessting questions
-how can i find the important relays?
-which signal use the s12 tach?
and

why is my ECU plug (RB20) complete diffrent from the manual pinout?

[Emperor]

FUUUUUUUUUUUUUUUUUUUuuuuuuuuuuuuuuuuu
ive snaped a bolt

ok, sh** happens

but

the special super expensive remover tool snaped too

sh**
must bring my head to a specalist and let the studs remove

lol

[Emperor]

finnaly a rad which fit


but soooooo small 30x30 cm LOL but very thick

[Emperor]

Benz VS Nissan


fit awesome (sr20 e-fan)





mehh must run a loop and add a filler neck

muhahaha no more CAS

[Emperor]

i start to wire the unit tmrw
i was abit sick today so i only could do abit work

[Emperor]

and so my journy into the land of megasquirt beginn

ive start with easy difficult hehe injectors


tps gave me a hard time to find since i was looking for a 3 wire plug-->ok nissan thx anyway for a 2 wire system

can someone show me a pic of the iacv plug? i only found the acv^^ lol why iam asking looks like noone cares about :-P i still keep on posting

[gerryb]

Its not that, its just that I don't think there's any 'current' Aus members that have an RB20 swapped s12, so no one has that info. Colin in the US is maybe the only one current that can help. iacv maybe = acv ? as in same thing ?
If it was me íf you haven't already I'd try googling RB20 and megasquirt to see if you could get lucky.

This guy advertises those in NZ and says he does a fitting service for locals. He would have done an RB20. Try to join that site and contact him, (worst comes to worst you could post your loom to him:

[Emperor]

thx for the link

but i dont think its such trouble when i found out in which wire i must tap in:closedeyes:

still waiting for the edis and than it should be more easy

and btw
my rb harness is already a cut down mess, cause i need the plugs but stupid as iam i forget to write down which plug goes where:suicide_anim:

also the color meaning is still unknown, for example
my tps have only 2 wires which one is 5v ref and which one is signal?

[Ruffels]

just sold my Rb Gaz, but i never altered the cas wiring when I did my loom, i just used a complete standard rb20 engine loom and computer, and just spliced off the computer for power, earth, ignition, fuel pump relay etc... so not quite sure what you need, unless your basically making a loom from scratch?

[Emperor]

jup ruffels

since some senors ,plugs etc are broke or missing its the best option for me
well iam soon done with the harness:thumbsup_anim:

wait for my edis and i can finish the thing

just must improve my soldering skills:whistle:

serious when i find out which wire is signal and which ground it start to get real easy


can some one show me where is the main relay? as you can see i must tap into 87 (hot when ignition)

[Emperor]

yeahhhh lights and starter work again:thumbsup_anim: also found the perfect place for my intercooler


my wiring mess

those fu**ing stupid manifold makes every work more complicated than it should

[Draconis]

She's in there and things are working! Very nice. I would keep an eye on the cooling and the engine's temp. when you get her finished. If possible, remove the intake plenum (top half of the intake manifold) while you work if that makes it easier. Just be sure to cover the intake holes and put new gasket stuff when re-installing the plenum. But for sure, the wiring will look like a mess. I have a picture of my wiring while the RB26 was going in and it was nuts.



Btw, I am really liking how well that intake fits. It's as good as ARC induction box. As Borat would say, "Very nice!"

[Emperor]

serious
iam already over that level:whistle: but seeing is believing right?




wasted spark FTW


seeing your wiring mess reminds me on my harness bevor i start to cut^_^
from the old harness is maybe 20% left! CAS and Maf stuff makes the biggest point:D

yes cooling is still a problem but it will do the job until my budget rise again and i can afford a custom one
a good e-fan and sidepanels will help alot and dont forget its a dual core->twice as thick than a SR20 RAD:o

my intercooler? yes that was the suprise of the year ..... a part which fit whithout giant mods on the body

[Draconis]

Looks like you got things well in order. Very much interested in seeing it getting closer to finishing. Well done so far.

[Emperor]

thx

haha i have a problem with my coil------->no idea where i should mount it
