  1. Hi mate, I noted your details from the durametric owners thread and wondered if I could have to use of the reader sometime that works for you? I note from the thread that you are abbots langley; I'm in Enfield so you're just up the road from me .

  2. Don't suppose you live on Abbots  Road do you ?

    there is a lovely 986 on there last time I looked :)

  3. Can't say I actually had to do this as I bought the whole instrument pod from a 996 but the original Boxster part can be modified (cut) to take the 996 gauges. Have a look at the Pelican Parts article: http://www.pelicanparts.com/techarticles/Boxster_Tech/90-ELEC-996_Cluster/90-ELEC-996_Cluster.htm The cutting is shown in figure 4 of the article. Looks simple enough with the use of a Dremel or the like.
  4. So an example of this feature to identify the current engine coolant temperature. 1. Identify the 'c-code' required - 6c in this case 2. Press the 'windscreen vent' and 'recirculation' buttons simultaneously for about 5 seconds: 3. Use the '+ and -' buttons under the left display to scroll through the 'c-codes' until you get to 6c: 4. Once the left display is showing 6c, press the 'central dash vent' button to display the associated value: 5. Now the engine coolant temperature should be on the left screen (89C in this case). Once you're done, either press the 'Auto' button to go back to norma
  5. It seems relatively unknown but the climate control unit of the 986 can actually be used to pull out a surprisingly large amount of sensor information from the Boxster's onboard systems. I've tried this on my MY2000 986 2.7 and it works perfectly; I'm not certain it works on every 986 as I've read that it doesn't necessarily work on newer versions. *** Disclaimer, I didn't acutally figure all this stuff out. I first saw this working on an MY2000 Audi A3 (which uses pretty much the same A/C controls as the 986) and found the following information for the 986 on the web a couple of years ago **
  6. Hi Bob, I'm glad you're finding the writeup useful. Good job on the 996 engine install BTW, I believe we have a forum member doing a similar job at the moment. In answer to your question, I believe the main boards in the 986 and 996 clusters were the same. Initially, I had the 986 code base (with mods to enable voltmeter, oil pressure gauge, etc) installed on my 996 cluster and it all worked perfectly, except for the analogue speedo calibration. The analogue speedo calibration was the main reason I had to go for the modified 996 code base. On that basis, if the operation of your main dials is
  7. I think I still have the EEPROM dumps on my laptop. If you want, I can email/PM the one I used in the end and see if it works for you?
  8. Part 5 - Coding, part 3 (Creating the final hybrid code) With the above information in mind, I could successfully modify the 996 coding to work correctly with the 986 systems, keep the PST2 happy and maintain the correct calibration of the analogue speedometer. From the base 996 coding, I had to make the following changes: - Copy the correct mileage (copy 00000000-0000000f from 986 code base) - Change the VIN (copy 00000018-00000028 from 986 code base) - Set vehicle type to 986 - part 1 (set 00000035-00000036 from ’09 96’ to ’09 86’) - Set vehicle type to 986 - part 2 (set 0000003b from '0
  9. Part 5 - Coding, part 2 (editing cluster EEPROM) (As mentioned before, I've only tried this on my MY2000 Boxter and I know of a couple of people who have done the same on similar age (or older) cars. I'm not 100% sure if the following will be suitable for CANbus cars as they have a larger EEPROMs. I expect it will work but have no personal experience of this.) This process may sound a bit scary but really isn't that tough. First things first, the instrument clusters will need to be opened up so you can get at the EEPROM on the main PCB:The PCBs of both 986 and 996 clusters are the same. And th
  10. Part 5 - Coding, part 1 (which method to choose) After trial fitting my new 996 dials, I found that basically everything seemed to be working, however, the odometer was reading the mileage of the 996 donor (happily only about 2,000 miles short of my actualy mileage). But, upon connecting my PST2, it gave a big fat "?" next to the instrument cluster and could do nothing further with the it. If I told the PST2 it was connected to a 996 rather than a Boxster, the instrument cluster actually came up fine (and everything checked out perfectly) but obviously just about everything else came up with e
  11. Part 4 - 996 instrument cluster installation I mention this step next as it depends on how fussy you are about doing a perfect job! :-) At a fundamental level, I found the 996 cluster installation to be basically 'plug-and-play' at this point. Referring back to my cruise retrofit guide (or many other sources on the internet) the original 986 instrument cluster is removed quite easily by: - Removing the mic cover and hazard warning button - Remove the screw behind the mic cover and hazard warning button - Pull cluster upwards - Remove hazard warning light switch and three cables from back o
  12. Part 3 - Installation of 996 oil pressure sender unit My next step was to install the 996 oil pressure sender unit. The original 986 unit is effectively just an on/off pressure switch to warn if oil pressure is dangerously low. The 996 unit has this function as well but also provides a feed to give a live reading of the oil pressure. The process of swapping the 986 sender for a 996 sender is very simple: - Disconnect the cable from the sender unit - Use a 24mm deep socket to unscrew the old sender unit - Screw in the new 996 sender unit and tighten with a 19mm spanner or crow's-foot wrench.
  13. Part 2 - Choosing the right Instrument cluster This seems to be a bit of a minefield of part numbers - looking through PET there seem to dozens of the damn things! Fundamentally, there appear to be two main types of cluster: - Older version for pre-CANbus cars (986 pre-MY2001). These clusters have BLACK, WHITE and BLUE connectors on the back and feature the older style digital segment displays. - Newer version for CANbus cars (986 post-MY2001). These clusters have BLUE, WHITE and GREEN connectors on the back and feature the newer dot-matrix style displays. NB: From what I understand, t
  14. Part 1 - Shopping List Thankfully I didn't need quite so many parts as for the cruise retrofit. I needed the following: - 1 x 996 oil pressure sender unit (996.606.203.02) @ £45 from OPC - 1 x VW electrical connector (000.979.010 E) @ £4.56 from local VW dealer - 1 x 996 Instrument cluster (996.641.105.02 70C) @ £110 from eBay ** See 'Part 2' for more options ** - 1 x 996 Instrument cluster cowl (996.552.060.02) @ £50 from eBay - 1 x Hazard Warning Lights button (996.613.121.00 A2) @ £13.54 from OPC - 1 x Surround ("Rosette") for above button (996.552.470.01 C53) @ £10.76 from OPC NB:
  15. Following on from my successful retrofit of cruise control a while back (http://www.BoXa.net/forum/index.php?showtopic=61570&hl=) the next mod I wanted to tackle was the installation of a 996 instrument cluster. I had a few reasons for wanting to do this: - I liked the idea of having the oil pressure gauge. My old MX5 used to have one, my MGB has one and it's nice so see exactly what the oil pressure is at any given time. - I liked the idea of having a voltmeter. Again, my MGB has one and since I had the alternator fail on the Boxster a year or so ago, it's nice to see things are workin
