hey mate,

well i have your program working on my laptop now (can't get datascan to work properly...)

its an awesome program

i take my PDA everywhere as its a phone/diary/resource (i use it to store all the resource data i need for uni), so it would be quite handy if i could work it on my pda

...but having a full-time pda in the car would never be something i would do as my car isn't hardcore enough for that..

sadly, i have abandoned the idea :)

we'll ill see if they work well first. if so, u can have one for the cost of postage, and ill only hold you to provide some good feedback/suggestions for future improvements :)

u already have the null modem, all u would need for perm car setup would be to mount it somewhere, and get a car charger adaptor.

i gotta save some face after insisting it should work :)

also would be good to find out how cheap a pda can be gotten to run it. the pda i got is pretty much the lowest spec ive come across (133mhz, 16mb) so it will be interesting.

shouldnt count chickens just yet though, best learn from past failures :(

will let u know when ive got them and whether they work or not.

Pete that HP548 loaded .net cf and ecutalk successfully. Now I'm waiting on the null modem and sync cable.

So far:

DIY Consult $50

HP548 $90

Null modem $6

Serial Sync $8

We'll be in business by the end of the week for the princely sum of around $160. Giddyup.

got the two jornada 540's today, tested both and they work pretty well suprisingly, given its only 133 mhz cpu.

updates sensors about 1-3 times a second depending how many etc. basically its fast enough to be cool/useful.

pretty happy. they can be picked up for as little as $40 on ebay (http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...item=9708012766). the racs_aus or whatever the seller is of that item regularly sells them.

Why is stuff always cheaper AFTER I've waited patiently and thought I paid a fair price. $40? Bugger.

Peter I'll paypal some money over to you and you can bid on my behalf when I upgrade the 548 :)

btw whereabouts in Western Sydney are you? I'm in Blaxland.

blacktown area.

surprisingly the 540's i got were actually 547's, ie 32mb memory. 547's supposed to be same as 548 except 547 dont have USB cradle, however this even came with a USB cradle :thumbsup:

one had a slightly duller backlight so im shipping it off to warren when he sends me his address :)

this one went for $30:

Ok Pete, next task: universal pda cradle/holder/something tidier than glue-on velcro to mount the pda on the dashboard.

Any ideas? I checked around but didn't find much. That said, I'm the guy that looked and looked and then paid twice what you did for a pda! :D

Nice score on the 547, sounds very nice. If it works as nicely like you've mentioned, perhaps I'll keep the HP and leave it in the car.

Good on you for shipping one to warren, there should be more of that in the world :D

something like this?

i havent looked in to car mounts at this stage as i dont drive my car enough/long distances to use it

Nice! That's what I'll need to purchase.

I ceased procrastinating today. I pulled the laptop apart, cleaned the heatsink, re-pasted the CPU, loaded .net framework, loaded ECUTalk beta and plugged it all together.

10minutes later I traced the power loss to AFM1. The voltage drops to 0.8V whilst AFM2 is still outputting 2.0V+ :) The car actually stalled at the lights tonight, due to AFM1 dropping out and the ECU didn't catch it in time.

I came home from work half hour ago and played around for a bit, trying to suss out which one was AFM1. I worked it out when I managed to trigger limp-home mode when I pushed hard on one of the AFM plugs.

So, I found AFM1 and it appears it is a connector problem. I thought it might have been a bad/corroded earth - I'll do a little more fault finding over Easter and hopefully clear this up for good.

Pete if you let me know your PayPal email, I have $25 that would have gone to the Datascan people. You offered your program gratus and I appreciate it mate. ;)

Successful operation on HP548. HP ActiveSync -> null modem -> Newkleer DIY interface -> ECU.

I felt that the display was much laggier than I am used to seeing on the P4 laptop. Then I read your PPC 'Known Issues' and I may have selected 6 or 7 bytes of data. That said, when only AFM and AFM(RH) were selected it did not refresh as fast as I would like. Price you pay for a 133MHz PDA :P

Peter the only other issue encountered was that the number of sensors available (R32 GTR) ran off the page and I was unable to scroll down to select.

I am very grateful for the time and effort you've put in to ECUTalk, hats off! Perhaps a nice Ipaq 4700 would do the trick :) I take my PDA everywhere I go so it is much handier than lugging the laptop and having it loose on the passenger seat.

Cheers,

Mark

and the AFM problem was dry joints inside the meter itself.

i dont think the slowness is due to known issue, its just that ppc u have. like on the now second news post on the site, the 548 is pretty much the crappest PDA speed wise u can get that it will 'work' on. the fact it works at all is pretty good - its a pocket pc 2000 (original ppc) which is now like 6-7 years old.

my testing was roughly 1-3 updates a second maybe, which isnt that fast obviously, but since the jornada 548's can be got off ebay for like $30-40, cant be expecting too much.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
