    Thanks Rob.
    Didn't realise you were using an ECU for the DBW. I'm looking for a standalone DBW system that can read the DBW pedal, operate the throttle body butterfly and provide a TPS output for an older ECU that doesn't support DBW.
    Mega squirt had one but it looks like the company was bought out or closed down. I'll keep looking. Thanks again
    PS. took a look at the specs for the KV8.. Looks good..lot of money

    Knocked over another little job.

    I'm using one of the BDE oil filter relocation blocks to make a little more room for the turbs, and also to help the filter clear the larger oil pan.

    Downside of that is now I need somewhere to put the filter. I'm using an Aeroflow thermostatic filter block, that conventiently has room for a combination temperature and pressure sensor. I used the raceworks sensor as 1) it has a DTM connection so I'll be able to boot the connector on the harness side for proper racecar things 2) it doesn't hurt that I'm a raceworks dealer...

    Anyway ended up settling on the nose cone for the filter location. Easy access, won't make a mess when I change it, room for the sensor.

    Had the local engineering shop weld a bracket onto the upright for me.

    A few coats of paint. Autolac have a pretty good product which is essentially two pack in a can. Costs a bit more but matches well.

    And installed with a Raceworks lifetime oil filter.

    So with the location of the Oil Pressure & Temp Sensor finalised I can map out the last little bit of EFI harness. Oh and no consider I've removed the sub fan, the AC condensor, the factory airbox, etc, I'm not concerned about putting the filter in front of the radiator.

    Looks good. Are you going run the front fan? I recently setup soft start and shut down on my cooling fans using those new nifty Hella Solid State Relays. Not cheap. $100 a pop.

    Just going to run the standard clutch fan - it seems pretty hard to beat in terms of airflow.

    I've got those two little fans on the oil cooler as they helped with stop/start driving with the previous iteration of the build - might have to look into a simlar relay setup although the current draw on the smaller fans is next to nothing by comparisson to the larger ones. 3A from memory although I'm not sure about the inrush current.

    Took a good look at the 350Z DBW pedal and knocked a a pedal for the ZED pedal using the 350 pedal position sensor.

    Nice work! Cheaper than a whole pedal!! Love it

    looking good, will you be making a batch of pedal adaptors? also I believe the v35 pedal is the same with out the alloy cover

    Yes I will get a few mounts cut at once and see if there is interest in them.

    The mount is easy to produce but converting to true DBW is not a small undertaking - not many ECUs can drive two throttle bodies and the work involved on the wiring and power supply side of thing is substantial. But short answer yes.

    Mocked up harness finished and laid out on my living room floor for measuring.

    The furthest point from the firewall is for the IAT sensor which is up near the intercooler. Good spot for the sensor as it won't heat soak, not so good for tidy wiring but it'll all be OK once it's in the car.

    And drawn up ready to start cutting some wires at last....

    Hi Rob, One of the many things I learnt when I worked for the PMG, later became Telcom Australia, now Telstra was how to make forms or what we call in the auto trade wiring looms. Back in those days we would lace (tie) forms up using wax string. You're off to a good start taking all the measurements but now you should transfer your drawing onto a forming board. Go out and grab a bit of chip baord board say 1800 x 900 and mark out your loom. Use 3" nails at all the branches and ends to tie off the end points. The main body of the loom (centre) will be the 2 sections that run in the valley. I'm sure you'll work things out from there. Done quite a few after market ECU looms over the years.

    Thanks for the generous feedback. I'm planning to do a concentric lay on this one although I'm not really sure how that's going to come together - I'm comfortable with the process etc but the layout of the harness doesn't really have a central trunk to work with in the same way it would following more of an OE layout.

    At the moment I'm waiting on a big big box of tefzel and an A/S connector and I'll start the actual assembly... will keep the chipboard suggestion in mind!

    nice one options are good for the market , i thought you could use elite 2500 and this [​IMG]
