ECU *again* but the americans cant help

[rnbguy]

okay ive sourced all my parts for my turbo setup on my ek civic to run ~6 psi. Now im upto the most important part, the ecu. I cant ask americans on their forums because their setups (distributor etc) is different. So here are my options and i need your help, aussie aussie aussie:

1) S-AFCI with 450cc injectors (cost $300 all up) im thinking i can change the timing at the distributor right? or will i need a timming tool such as mtd or itc (another $300)

2) FMU : dont want it
3) hondata: quoted $800 for ecu and chip , then $850 for a tune. seems pricey but still keeping it in mind, is there a way to reduce how much their asking, such as getting my on obd1 ecu etc?

4) crome: (this is what i prefer but..) mapped obd1 ecu + harness ($250 shipped), tunning im not sure on costs or who in sydney does this? I need to know other requirements for our car to get this to work, some say a new distributor, others say you can just get a plug, input needed?

smart asses you dont have to reply to this post only people with knowledge please as i need to get this turbo in soon.

[Edgeauto]

What motor? If its a Y4 to run hondata or crome you will need a Y8 dizzy and make you own harness and run new wires to the dizzy for the extra sensors and to the injectors. If its a Y8 you can just plug and play with a harness and a OBD1 ECU.

[rnbguy]

yep its a Y4 so what i defenitly need is a Y8 dizzy and to run a few wires from injectors to new dizzy thats all?

also can the current dizzy have its base timming changed at all? or is that only possible with the pre 96 civics?

[ACTI0NMAN-1]

i believe toda can tune crome for you up in nsw.

[ECU-MAN]

you have to run wires from the ecu to the new dizzy. not the injectors. you can do jack with the current dizzy.

Thats correct:thumbsup: You will have to run 4 wires to the dizzy for the CKP and CYP sensors and an extra 2 wires to the injectors because ATM No. 1/4 and No. 2/3 pulse together. Base timing is set by turning the dizzy(sorry I don't understand you question):)

[rnbguy]

ahh right thanx, i see my current dizzy only has 7 wires connecting to it so i take it ur right i need a new dizzy for a obd1 approach... ill probably start with a safc usage first to practice tunning, i know this approach advances timming ive heard alot of people do turn back the timming on their dizzy 0.5 per pound of boost, can i adjust timming on my current dizzy by manually turning it back myself? how risky is this approach for say 8 pounds of boost?

what is another alternative to retard the timming? i know itc is one but their impossible to find... (in australia for now)

Um... That's a great price, as long as that person knows what's going on!

Dyno Dave is the man for jobs like that! You pay for quality, that's what i say. He's the only one that tunes my H22 turbo, with Hondata.

[rnbguy]

yeah i belive its a good price too but not for the budget im after for this project..

its really easy, i did this 2 days ago.

1st. start the car and make sure your idle is correct and make any idle adjustments. shut off the car
2nd. use a paperclip to jump the service plug. you will find this behind the passenger side kick panel (where the ecu is) its plugged into a green rubber boot thing. straighten out the paperclip then insert one end to one of the 2 plug slots, then insert the other end into the other plug slot.
3rd. plug in the timing light to your battery and the number 1 spark plug wire. you can't really screw this part up.
4th. start the car, the check engine light SHOULD BE ON (because of the service connector)
5th. check your timing, (for d16y8 is +/- 12 degrees) should be in the middle of the group of 3 notches on the crank pulley. they will appear to be still.
6th. loosen the distributer bolts (you might want to do this with the car off if the radiator fan cuts on)
7th. if your timing is off, rotate the distributer (yes while the car is running) and keep checking your timing to see if it is where you want it.
8th. once it is where you want, tighten down the distributer.
9th. remove the jumper from the service connector.
10th. jump with joy and crack open a beer (this is mandatory, the car will not run properly if you skip this step)

the rest is self explanitory
have fun.

got this from turbod16 as a reply to how to alter timming, what u guys think?

[Edgeauto]

Personally i wouldn't run a turbo set-up unless i could adjust the timing in the boost columns of the ignition map.

[rnbguy]

i would if i can grab a hold of a timming controller, their all overseas, im still looking...

[rnbguy]

dooooood all the tuners overseas are saying i dont need to change the dizzy????

they say it the same inernally as a obd1 dizzy

[Edgeauto]

Here's a pic of a run of the mill OBD1 dizzy. Remove your dizzy cap and have a look for yourself.

So the obd1 dizzys are a magnet pick-up and obd2 are an optical pick-up.

[ECU-MAN]

So the obd1 dizzys are a magnet pick-up and obd2 are an optical pick-up.

only d16y8 obd2 is optical, others are the same magnetic type like obd1.

[Edgeauto]

You can use OBD2 dizzys with OBD1 ECUs just notdizzys of D16Y4s

[rnbguy]

wait this says:

only d16y8 obd2 is optical, others are the same magnetic type like obd1.

so then d16y4 is like obd1 which means itll work with obd1 ecu right???

but then this says:

You can use OBD2 dizzys with OBD1 ECUs just notdizzys of D16Y4s

but didnt we just say obd2 ecus are the same as obd1 ecus (other then d16y8)

is there a misunderstanding here?

[rnbguy]

on a similar note, the D16y7 dizzy must be different to our D16y4 dizzy as in america you dont need to change the d16y7 dizzy to allow for the obd1 ecu, you just change the plug.

[serpo]

wow im so confused im so not changin my ECU LMAO

[Edgeauto]

d16y4-cxi and gli civic have an optical dizzy and no CKP and CYP sensors:thumbdwn:
d16y8-vti civic have a magnet dizzy:thumbsup:
d16y7-yanky civic aslo have a magnet dizzy:thumbsup:
just a typo by ecu-man

[rnbguy]

thanx also on that same note, do optical dizzys (Y4) mean i can or cannot modify timming directly (manually) at the dizzy itself

[creativepunka]

You can still adjust your base timing (@ the dizzy). It just uses a different way to pick up the crank rotations for the ecu. If you could chip the d16y4 ecu then you wouldnt have a problem, but you cant.
A y4 ecu can only read a y4 dizzy (optical).
And a y8 ecu can only read a magnetic pickup type dizzy. Y8, y7,y1 and so on.

[Edgeauto]

^^^correct^^^ I also test fitted an obd1 dizzy off a eg gli(d15b) which i had laying around on a d16y8 and it bolted and lined up perfectly, so i dont see any reason why you use 1 of these too.

[rnbguy]

very very useful information thanx heaps guy.

[rnbguy]

ive just bought a SITC hopefully it wont be a problem with the ek1 ecu :)

[ECU-MAN]

just a typo by ecu-man

lol blame me

I said


only d16y8 obd2 is optical, others are the same magnetic type like obd1
