If you are in the vicinity of the Stuart highway this week keep an eye out for the solar cars. There will be a display of the cars in Adeliade next weekend. the web site is Global Green Challenge / Home Mike

Hello all, My VX SII Acclaim has/had a feature when you stop the engine and open the door the headlights will turn off. However, in the past few days (not exactly sure when) it has seemed to stop working, now when I leave the car the lights are still on. I guess the fault lies in the guts...

I have finished the IR design so I no longer need beta testers for that. I now am looking for someone(s) to test my steering wheel to PC interface Hi all, I have finished my circuit for my steering wheel to IR converter. I would like to know if anyone is keen to test it out for...

Hi all. So I have built my steering wheel control to IR converter (JVC only ATM). I have successfully removed the old stereo but now I have to bolt the new one in. So I'd like to know if there are any good howto's about the place. Mostly I need information on how to remove the side...

Leaving aside the question of if it is the right thing, I was thinking what to do with the government handout. I am thinking that if we all go out and buy a plasma then it will be for nothing and perhaps only prop up china for 30 seconds. With that in mind I am going to pay a local installer...

Hi all, I am after the loan of a vt or vx steering wheel radio controls. I am building an adaptor to sit between the controls and an aftermaket radio. ITEM: vt/vx steering wheel radio controls LOCATION: Newcastle NSW CONDITION: any DELIVERY/PICK UP INFORMATION: I'll pay for...

I just bought a VX SII. Up in Newcastle we have had two decent falls of rain since I got it. Both times the rear footwell on the LHS has a puddle of water. I cannot see where it is getting in. Any Ideas where I begin my search? Cheers Mike

Hello all, Today as I went to start my car it turned over but no spark. Mr NRMA came along and got me going (most of the way home) by thinking it was a dodgy connector, gave the plug a wiggle and it lept into life. Tonight I removed the coilpack/DFI module in an effort to get to the...

Hi VT-VX type people. Thanks to some hail in Newcastle my VN is now no more. I was thinking of buying a VX to replace my car some time ago but now I have to start looking seriously. So I have two questions (for a start) 1) How can I spot the difference between a VT and VX. ie the...

Hi all, I have just got a set of new injectors and have skillfully managed to lose my gregories. Can anyone supply me with a link or a step by step guide to removing the old and replacing them? Or fire off a scan of the pages in the gregories? Cheers Mike

Hi all, Like most VN's my auto is now so bad that I have to get a good book to read while waiting for it to engage in reverse when cold. I went and bought some nulon auto fluid additive that claims to fix/help worn seals (a known culprit in the slow gear selection). My question is that...

Hi, At work I have got the job of looking for impressive videos of a safety type bent. If you have links to downloads (ie not google video as I cant install any players on the video I show it on) I would appreciate it. To start the thread take a look at this site, it is the US NAVY safety...

Every time I drive past a bowser this idea looks more attractive. Would someone who knows a bit about the rear diff setup in an IRS commodore take a look at the spec sheets for this UQM motor and see how difficult it would be to fit in the back...

Hi all, I mave made a number of serial MAX232 ALDL circuit boards for use in VR/VS/VT, they are my own design and work with V8's. This is a pre-etched circuit board BUT to make you will need to, 1)prepare the board, clean off the tracks with turps then meths 2)drill the board (0.7mm...

Not sure where this one should go so I put it in the pub out of the way. I was wondering, has anyone heard of a throttle body that instead of a butterfly valve it uses a iris (think like a SLR camera). I just thought of it and wondered if anyone has tried it. The advantage as I see it is...

I suspect the answer to this is a negative. In the memcal how interchangable is the knock sensor and limp home resistors between cars? For example imagine I have a VN6 and I get a memcal from a VP V8, remove the eprom and put a VN V6 program in. Will the knock sensor (if fitted) and CAL...

Hi I recent won (the only bidder gotta love that) a 16183082 "remanufactured" ecu from a VN. The bloke selling it claims it was from a wrecked vn and as he was selling other stuff from a vn and the memcal has a ATJR 4357 which according to Bob's memcal page is a '89 VN I have no reason to doubt...

I was about to point someone to my great opus in the electrical section about ecu plugs and stuff and I found that it has fallen off the end of the page not to be seen. What is the timeout for threads? Mike

Now you all done it. In a vain effort to stroke my ego I offer my opinions on most things scientific. I Have a Ph.D in Chemical Engineering and a degree in Electrical Engineering, so I can bulls%$t my way though most engineering, physics and chemistry questions. If anyone is wondering about...

Sorry have I missed something? WB/NB O2 that one has a 0->5V output the other a 0->1V output? Is that it? Mike

I am cleaning out my electronics junk pile and I have a box of stuff that is otherwise going in the bin. The box has a lot of diodes, electrolytic capacitors, a few bananna posts, some 75 ohm coax, some 1W dc-dc converters. There is no car related electronics, just bits and pieces. If...

Carbon fibre engine covers. Which to make? Over a family BBQ I got to speaking with my uncle who is an expert on all things composite. We were talking about making some engine covers for beer money, I own a dodgy VN and as such am not too interested in one for my car (although the intake pipe...

Hi all, I am about to embark on changing the Y piece on my S1 VN. By Y piece I mean the bit after the headers and before the cat converter. My question is how much of a pain is this to change? Can I do it whilst the car is on the ground or is it better on the stands? I am also...

Hi all. I am going to be ordering a bunch of OBDII plugs from overseas. They are used in the VR/VS/VT and the GENIII data cable. These are the blank plug and shell only. I get them for about $6 US plus postage (bulk order). If any one wants a few I can tack them on to my order. Bear in...

I have bought a delco 808 from ebay with a memcal. I am planning on playing around with some piggy-back boards. As I don't want to have my engine attached when it all goes pear-shapped I would like to simulate a motor. Does any one know of (or has a good link to) information to fool the ecu...

Hi all. Those of you that have followed my stupid questions on memcals may have guessed where I was leading. I recon I can build and program a microcontroller to sit inplace of the eprom in the '808 memcal. It would then be loaded with an initial rom image. It is then possible to change...

As far as I can workout (ie by reading the other threads)the 1227808 runs the 128kbit (16kB) rom. If you substitue a 256,512 or heaven forbid a 1 Mbit chip you can select the "program" by altering the extra address pins. Now what would happen if you could do this cleanly (no mechanical...

This is the cable for linking a GENIII motor (V8, VTSII and beyond) to a laptop. It is based of the elm32x chip so it will work with a bunch of software (some free, some not). This cable is also optoisolated which is an advantage for 2 reasons 1) you car cannot kill your laptop and vice...

ECU DATA LINKS I have made one or two of these so I’d thought I would share some info I have found to help anyone who wants to make their own. VN/VP: There already is an excellent thread on this topic on the VN/VP forum http://forums.justcommodores.com.au/showthread.php?t=5723. But I will...

Calm down this is just a hypothetical (at the moment). On SBS they have a news show from the states and from time to time it has a story about GM's financial woes. Now the question, what or how would holden survive/change if the parent company was to dissapear or become serverly affected...

I like most VN owners (I guess) have done a very good job of ignoring my stuck open thermostat. As a result my car rarely gets to temperature. I was reading a bit about ecu operation and heard something about entering closed loop mode. As my water never gets warm, will my ecu always run...

Just thinking the other day driving a 4 cyclinder car and not seeing the fuel gauge move..... What would happen to an V6 engine if you were able to switch off one of the cylinders? I imagine that you would need to change which cylinder didn't inject each time otherwise you would be out of...

OK so Mike being very poor, is going to change his trans oil himself. I am planning my great excercies and get stuck on the last point. Basicially I need someone to tell me that it is all going to be fine and I am being a fool. 1) Drive car up on ramps 2) Allow to cool (we dont want...

On Sunday September 25 the race begins. I advise anyone who can get near the Stuart highway to take a look at the these cars. For those of you who don't know the race is from Darwin to Adeliade with a car powered only by the sun. The average speed of the top cars in this year's event is...

Before anyone leaps down my throat hear me out. With fuel being the stupid cost it is and biodeisel being relatievly easy to make my thinking goes like this.... People have potted a 3.8 V6 from our favourite car into a hilux ute. You can get a Hilux motor that drinks diesel so the great...

Hi, I am playing around with ECU cables. I have found some stuff for the VX onwards and I need someone to take a look. I need someone to confirm that the holden uses the J1850 VPW protocol on the OBDII plug (under the steering wheel). All is required is a quick look, no pulling anything...

Random musings from a deranged mind. Would it be possible, when posting a new thread for there to exist a check to see if a similar thread already exists. Perhaps this 'feature' could be for people with less than x number of posts. This could limit parallel discussions on "can I chop my...

Just wondering, following on from the "flash you lights" poll. Has anyone here stopped to tow a stranger's car off the road or to a safe spot. Mike

I have designed and got working a USB to OBDI cable. This will work with a VR -> VT. The software to use is EfiLive V4. It has an evaluation copy that will run until the end of this year. I have one cable ready to go and if anyone else wants any more it wont take too long to make more...

Assuming anyone cares. But after 8 weeks or so in various casts and leg braces my Achillies now reaches my foot. So after an 8 week rest I can now drive again. The first thing I have to do is sort out my rego. Which pedal is the brake again...... Mike
