Maybe I will hook it into GND (Control Systems) Sounds like that may work? Other Ideas?

So I have this kinda working, the ground seems to be really tempremental. Evo scan connects gets one set of data then fails then I wriggle the ground and it comes back etc etc. I will have a look at my diagrams now as I may just splice into an actual loom ground wire...

Not a bad point at all. Though I am pedantic and want to do it neatly PLUS I really cant be assed running all that wire heh... Where's ReubenH and his mint wiring diagram skills when you need him ;D

Haha yeah good point! I have just found this in the stash of pinouts I have: Now just to find the one from the TT ecu which is seeming more difficult that I thought!!

No what pins at the ECU are TX/RX ie pin 3 = TX or pin 3 = RX I have got an obdii pinout with SSM RX/TX but I need to know it ECU side. Thanks so much for your help so far Garry it has been invaluable!

All I can say is WOW!!!! 8) ;D I will definitely try this but surely I can find where those TX/RX pins from the OBD plug go to and just re-locate them to the right pins on the ECU?? I'm fairly sure with a tiny screwdriver it is actually possible to get the little pins out and put them in a new hole... EDIT: what pins are RX/TX??? I did have a look at my manuals but cant find it lol

So I got the cable, nicely with a subaru logo on the front (Nice one Garry really made me laugh) ;D Can't seem to get it to initialise though. Maybe during the single turbo conversion the pins changed??

you can add a huge amount of space with gaskets. More than enough to drop the compression ratio

yeah if a garage was to do it, probably be better getting an STi engine ;D All my prices are with me doing the work / clubsub helping out hehe

Not necessarily. Head gaskets probably be about $500 max

Take engine out and then measure up etc. There is probably a chart floating around somewhere listing volume of different blocks. Then just get the headgaskets to match. Yeah its not going to be cheap but cheaper than getting a whole new engine

You could always just get thicker head gaskets...

So an update for anyone else who is watching, Garry is sending me the cable to try out (thanks heaps ;D) and I have just ordered a $14 Male OBD2 connector from carplugs.com Will get this all up and running with evoscan (hopefully!) and get some pics up and possibly a how-to

work out the litres per hundred k's is what I meant

I reckon I used about $250 on petrol and only did about 800kms max (over xmax/new years)... Work that one out ALTHOUGH, a lot of that time I was on full boost in a passing lane

Is the block up to it! heh I thought I read somewhere that the v5/6's can do it too... maybe I'm mistaken

Yeah but the ELM chip does all of the INIT stuff that I really cant be bothered coding for. ALSO, if SSM is TTL, then thats perfect but info on it seems to be quite hard to find. ie what pins does it operate on, how to initialise, what commands does it accept (if not the same as obdii pid's) But thanks for the info so far - its awesome! [quote name='gazzy2000 said: Hey chrisjunkie... I have a TTL-232R (USB to TTL serial) cable here that i was using on my v5/6 ECU. Log1call was helping me get it connected with evoscan. I am happy to send it to you to borrow and if you get it connected and want it just give $20 Let me know? Let you know... b]YES PLEASE![/b] It would be really cool to use to get used to SSM comands etc. Will borrow in beginning but may find that my netbook in a mount actually is a lot cooler than an LCD AVR circuit + it requires less programming Are you Auckland based? ALSO, do you have the software? EDIT: never mind, seems like they find it hard stopping google getting onto the download link page :LINK HERE (not sharing a pirated link merely a search result to a page hosted on THEIR servers)

is SSM or OBDII TTL levels? Cant seem to figure it out

So I think I will just spend the money on the ELM323 chip. Supports ISO and does all the OBD bus init etc. MUCH easier solution PLUS it operates at TTL levels. Will post up when I do get this going at some stage P

Im not seeing any fuel reg vac line??? yeah we put mine under the manifold like that too but that is definitely tidier and nicer looking with the STi red ;D

Damn work haha I would have done it fairly similar too... oh well saves me a job

ah cool! SSM - completely forgot about that! Will have a wee look around now hopefully there is enough info floating around on teh interwebz.. EDIT: doesnt SSM only support newer models? RomRaider doesnt seem to support a v5/6 sti ecu EDIT2: Will have a better look tomorrow. Bloody tired now and not thinking straight

Ah ok, so even though there is 12v available on the port, the k line is still only a 5v line? All im curious about is how do i send and receive? I mean TTL serial has 2 pins whereas on the obdii plug there is just the k line. Can you remember where you found this info or even the baud rates? My original post's link, is that the way to send and recieve on the k line? Haha sorry if I'm being real noob but im new to this obdii stuff and whatever I put into google gives me pretty shity results. Cheers, Chris

If Reuben doesnt beat me to it, i'll do it later on tonight... You dont have to go to coil packs (what you are thinking about when you say on top of the engine). I still have the individual coils but there is still re-wiring necessary. Check back tomorrow and i should have the diagrams for you!

thanks for the awesome reply! Not wanting to interface with computer rather with a pic or avr programmed to diplay stuff on an lcd. Will program this myself. Can i connect a max232 chip straight into the l and k lines? Looked at the elm chips but would rather not spend 30us if i can do it with cheaper chips. Any more info would be aweome!
