    The R32 wouldn't be too far ahead in G forces etc than your beast. Seriously, it would be fine. It's the one part on the cars that really gives zero problem. Check the belt occasionaly, and drive. I'd run one on a streeter no problems at all. The trick is mounting the tank somewhere that the car doesn't oil fume excessively (boot and vent it). That's really no more of an issue than getting the front mounted catch can breather to not stink up the car.

    Maybe have a chat to the guys at C&j Motorsport. They're good guys despite their *somewhat grumpy demeanor* (they have a low dickhead tolerance but you're not one), and have always tuned the cars and had them very reliable. Whether they can work with your ECU I'm unsure.

I've also written some code for a PIC-18F microcontroller that reads the serial stream from this tech edge and will produce an output serial stream that uses the innovate protocol.
    I got the techedge DIY unit, was pretty dissapointed with the junk case they give you. Its just some generic piece of crap plastic case from jaycar (probably $2) with some hack job cutouts for the various headers and plugs. Their site is absolute crap, and their support is possibly the worst ive ever had. My kit came with a couple of bits missing, sent 4 emails over 2 weeks with no reply, then called them and he acted like I was wasting his time (because he was going on a cycling trip in 1 week) and he said he didnt have time to do these sorts of things.

    The dickhead has no idea what it means to run a business or support customers when he screws up. That said, they shipped it out quickly when i bought the unit, I would just get a prebuilt one if I was doing that again. Or get a different one all together lol. No one needs all that stupid logging crap on a wideband

    Define "too far" . Although seriously, I was Probably more referring to the car in the earlier, Dutton type days. It's was only on 265 rubber and no aero or suspension geometry alterations. In fact it's still remarkably "stock".

    Haha yep! I program logic controllers for a living so when I saw the logic builder in advanced mode that was a revelation. You can program it to do whatever you can imagine. As long as the ignition and fuel timing outputs are accurate its the ideal ecu for me. Some find it awkward and confusing, but its speaking my language.

    Only thing close is the new fully programmable motec ecus at about 5k a pop.

    fine
    911 has it from factory, it's been good. but holds a lot more oil so takes longer to warm up though.
    i would have assumed if this is a street car mainly, there would be better ways to spend the money though?

    911s have had dry sump for donkeys years. My mate has a 67 engine that he's always messing with. The dry sump system nerve seems to miss a beat.

    it was quite an experience, I'll agree! Funny I was pretty happy with the case, needed the swarf trimmed off but looks good in black and everything fits well fully assembled.

    I heeded your advise about customer service so i didn't even bother getting in touch with them with my issues, it probably took an extra 2 hours work to sort out the problems i encountered, the root cause of which was poor or scattered documentation of known faults.

    the documentation is woeful and scattered all over their website. (Takes me ages every time to find the serial protocol info page) and there are several mistakes on the PCB. one of which is a dead short between 5v and gnd on the Red LED control circuit which renders the whole board inoperable... it is mentioned in the instructions on 3 pages in 3 different ways and no note on the PCB layout graphic. I found it checking the assembled unit against the processor schematic, and after cutting the track on the PCB it functioned correctly. there are two other faults in the PCB design that need to be corrected with patch wires, and its Rev 2 of the kit! Oh and one of the smd caps soldered to the preassembled wideband board had broken off in transit so that had to be resoldered back on, which was fiddly.

    other problem I had was poor serial comms to the unit. very patchy...spent a bit of time checking for bad joints, then i saw the parts list for the serial chip stated an HIN202 was to be used, but my kit was supplied with a MAX232 instead.. the HIN needs 100nf charge pump caps (that are the ones supplied with the kit), i checked the datsheet for the MAX232, and it needs 1uf caps instead.. so off to jaycar, got some 1uf tantalums, I had to work out the correct polarity direction before installing them but now everything is rock solid at 19200 baud. i'm not sure the cap size is that critical in this application, so maybe it was just the rework randomly fixed a cold joint. but who knows. using the chip makers specs has to be the better way.

    display is very fast (10hz digits, 50hz bar graph), and thermocouple inputs are reading correctly with good response.

    but if you're not familiar with electronics and ICs i would definately not recommend the DIY kit. if i had to rely on tech edge support to diagnose my issues, from what i've heard i'd be waiting a long time. but if anyone wants to give it a crack i'm happy to help them out.

    Hahahahaha that sounds fucking terrible even for a DIY kit.. its beyond what you would expect a at home DIYer to be able to make work

    Im very familiar with component level electronics and id do a credit card reversal if i encounted that bullshit

    Nice work Alex. What a pain in the arse. It sounds like you got there in the end. That was a good pickup on the MAX232 requiring different caps.

    Car is booked in to fit sump, breathers, quaife front diff, HKS2530s, coated midori seibi dumps and mines front pipe.

    finished the design on the Serial protocol Converter too.. nice and simple. input port is centered, output is offfset. Fab will take around a week. will post the code for the PIC18F when i'm finished too. will be a useful bit of gear for converting one known protocol to another. currently powered by 12v on Pin8 of the input rj45 (techedge supplies this) that feeds a 78L05 5v regulator. but you could add separate power terminals otherwise and feed it a separate 12v, or remove the reg and give it 5.

    Yep

    Sump -10 on passenger side to head drain, 2x-12 on drivers side. One blocked for future, one piped to oil cap.
    Diff
    1.2mm restrictor (this one is shit because head needs to come off just for this.. New studs/head gasket..)
    Nitto Rear head vent/drain

    Anything else while its out?

    Drunk and on holidays

    Mines r34 ran 258 x 10.8 lift cams

    Seems to work. a heap of local sydney lads swear buy it( mostly cock lovers)

    I guess that means the head needs to be stripped and clearanced for the huge lobes too?
