Here's a pic from last night's construction efforts, before I wired up the grounds.

It's getting tested on Thursday this week, assuming the engine is back together.
Juhuu,
This is great news,
I have just ordered a new board, so i can install it in my Legacy turbo, are you going internal map, or still using external?
/Skassa
Internal 3 bar MAP - the test subject only has a MY93 MAP that isn't up to the job.
OKay,
IÃ,´m really looking forward to hear, if the trigger system is working :).
/SKassa
Will this be for sale ?
And at what price.
It will be for sale, assuming it all works!
I'm not going to put an exact price on it yet until I have got the first one working reliably, however I am hoping it will be a similar price to the Nissan S14 adaptors.
Did you have any luck on the startup of the engine?
Did the trigger config work?.
regards,
Skassa
The engine's still not properly together. Slight problem with getting the turbo delivered :(
Hi.
What about the flyback wire, when mounting it pnp?
IÃ,´m about to assemple my vems, and make the wiring to the 4plugs in the loom,and would like to know if this is just left out, or do i have to make a new wire for that?
Regards,
Skassa
There's a couple of +12v feeds to the ECU. One of them is definitely for flyback purposes according to the wiring diagram.
I'll see if the whole thing works at the weekend - the engine is finally built!
Okay,
I did not check the wirediagram, i just looked at the pinout,
are you using the stepper to run the ignition module, or runnnig it some other way?
Thanks,
Skassa
I'm using both the water pump and fan outputs for the radiator fans, so I'll be using IGBTs to drive the coils. (This will be done directly if the ignitor unit gives me any problems)
The secondary reason for this is that my v5 RA has a 4 wire stepper, so if that ever gets VEMSed, it'll need the stepper driver to be a stepper!
I have today been working a bit on this wiring on my vems board,mounting another lm1815 chip to make the second vr input trigger.
So it now got primery and secondery trigger made to VR
I just saw this..

As you can see the tps voltage goes from high to low, and not the otherway around,
that dont seem to be suported in megatune,
So do i just switch + and - on the tps??
I can also see that i have a lot more wiring on the oe plugs, then you do??
I dont suppose you are going to run it all with VEMS
Regards,
Skassa
VEMS will take TPS going from high to low or low to high.
A lot of the existing wiring is for things like MAF, Lambda, A/C, and so on.
Okay, then itÃ,´s no problem with the tps.
regarding the lesser wiring, i can see it says, before ground wires, which there is lots off :)
I've never run out of grounds on any of the adaptors that I've made, but there arent too many spare ;).
The 5 that come from the VEMS are joined together (ground cluster) 12cm from the EC36 plug, then I usually take the ground on the chassis plug that is specifically a sensor ground, add that to the ground cluster, then use that wire to give the serial plug on EC18 a ground.
Then you'll need one to connect the sheild for the wires to the VR inputs.
IÃ,´m also on my way now
(http://img.photobucket.com/albums/v41/Denmark/Legacy/legacy053.jpg)
ItÃ,´s setup for 2 Vr sensors, EC18 pin12(secondery) that is showed as EC36 pin13 in the Phatbob manual!!
I just run out off the crimping, but will add it when i get some,
this is the complete wiring,
just IAT and wideband missing, so itÃ,´s,
boostcontrol,aircon cut relay,fans, iac, knocksensor,mapsensor.
The ignition is setup as, the first 4 ch are logic,and the 4last are with fets, inj fet 1234 are injector 1-2-3-4, injfet 7&8 are iac close& iac open
aircon cut relay p259 ch0, to cut aircon when going wot.
fan control p259 ch1.
then i just need to be able to configure a tacho output to the cluster.
/Skassa
You dont seem to have the grounds joined... Likely to kill the p259 without it.
Okay,
I just didnt thinkit was nessery,
I have all the sensor, and shield on pin26,
and the rest on the last four grounds, that are internaly conneted, is it really nessesary to connect the externale?
/Skassa
Its VITAL thats why I drew:

Okay,
I will put a wire a cross the grounds, then :)
Thanks,
I did the last time acutully burn the p259 chip, so that could be why ::)
/Skassa
Its easily done
Yep.
Did you see that you in the manual writes that itÃ,´s EC36 pin13 that is for a VR sensor, but itÃ,´s EC18 pin 12.
No i just need the time to plug it in, to see if i can get at trigger signal..
/Skassa
Dnb,
Did you have any luck with getting the engine finished, and if.
Have you tryed ,if the trigger setup is working?
Now that i have put a wire across the ground wires,
I will today try to plug mine in, the problem is that i dont got a 12v supply,so i have to put it into the car, to test.
and i dont even know what firmware that comes with my board(number1484).
/Skassa
It will probably be something around 1.0.3x to 1.0.5x
As for a 12v power supply... I use a spare drive power connector inside my PC the VEMS only draws a few milliamps so you can have fun testing it on the bench.
Thanks,
Do You still think that i need to put in the older firmware,like 1.0.73 ?
Smart move with the power, but i will now go and plug it in the car, and try the subaru setting that is written on Wiki,and see if i can get a cranking signal ::)
/Skassa
1.0.73 is the firmware to use, its running hundreds of engines for over a year now.
I think you need to start afresh with the config and tables for this install.
Sorry for my absence - no further progress on the VEMS side of my Scoob project. I got caught up quite badly in "real" work
Okay, i know how it feels, i would be a lot nicer, if the same money con into the account, and didnÃ,´t have to work for it,
then there would be better time, to project like this :)
Maybe you could review the trigger, injector and ignition settings, to check if it looks right?
