  1. Its a 9.35:1 engine, and with the procharger c-1 running a 6" crank pulley and a 3" charger pulley its giving only 2 - 3 psi of boost, it has livened it up abit.... Those pulley sizes were given by procharger tech support for this engine as a safe start. Naturally 2 psi dont really need a ton of fuel or afew degrees of ign retard. Its running the 28 degrees advance. 12.5:1 afr under boost. Standard flapper injectors (with resistor pack) I have got some 3" aluminium round bar off ebay to make 2 more pulleys for the charger. One will be 2.5" the other will be somewhere between 2.5" - 3" I have a 3.9 inlet manifold and fuel rail, while the 3.9 injectors are not much bigger i understand they are more of a "standard" fit. So i can fit all that and easily source some high impedance big injectors that will fit, and do away with the flapper resistor pack. As for megasquirt vs omex vs any other engine management. Megasquirt has been submerged, iv cleaned mud off it, its never gone wrong, and if it did i could find the info and buy the parts to repair it because its open source. One of my interests is programming pic chips, so im wondering how long it will be before i decide to doctor megasquirt to do something different.... Its opensource so i can : ) i dont know enough yet to do it like. Professionals mite slate megasquirt, but the guys who wrote the code and designed the board for megasquirt know more then most professionals who fit other management systems. With megasquirt.... If you desire it create it yourself. + by next week i will be logging megasquirt with my android phone / motorola xoom tablet hopefully.
  2. Supercharger = Procharger C-1 Blow off valve = Bailey recirculating dump valve (demon tweeks) Metal plates are figured out by me with some card then scanned at a laser cutting place. The one that bolts to the charger its self I drew on cad then exported to DXF Silicone hose elbows EBAY Brake check valve (stops boost entering your brake servo) EBAY from a turbo saab. Water cooled intercooler was a used item from a friend. but they are available from http://www.chargecooler.co.uk Crank pulley from a 300tdi I think, but bored out and a Megasquirt / EDIS / Rover V8 crank spacer welded into the middle of it to get the stud patten. Boring out the 300tdi pulley The spacer on the back is just afew bits of tube that I turned so it was a close fit against each other then got welded while bolted to the pulley and another RV8 crank spacer.
  3. Yes a place in the alternative land rover manual would be good : ) I placed in carefully in the bin inside a matchbox lined with cotton wool..... however if this happens again I will keep this in mind.
  4. Once upon a time a spider lived in a fuel gauge.... Now we all know spiders like to live in land rovers. They do a good job catching flies, However flies dont often venture into fuel gauges so im not sure why it had ventured into said fuel gauge. Im also not sure what type of spider it was? It was small with 8 legs. Anyway a part of living involves dying and so the spider died.... The gauge then had the front cover un crimped and glass removed so the spider could be removed This was then refitted You can tell it has been tampered with but you dont see the back when it is in the binnacle
  5. If you connect the Brown / Blue wire to 12v and the pink wire to earth this is what the alarm LED looks like.
  6. Best just go check i switched it off before i go to sleep. its only got to go to 97000.
  7. My code for the Pic now looks like this Program Speedo main: ANSEL = 0 ' configure AN pins as digital I/O ANSELH = 0 TRISB0_bit = 1 ' set PORTB to be input TRISC = 0 ' set PORTC to be output PORTC = 0xAA portC = 0 while true PortC.0 = 1 delay_us(195) portC.0 = 0 delay_us(195) wend end. I have changed the delay to 195 microseconds. The speedo now counts at the speed of **** flying from a shovel. 175 micro seconds and the speedo does not count... like you said, its too fast for it. Remember if these pulses seem much smaller then what is expected, my pic is running with its internal oscillator so timing will not be as accurate as using a proper crystal. Anyway its now roughly moving at 1110mph.
  8. there happens to be a td5 kph speedo on ebay item number 170658501435 2 bids £10.51 5 days or so left. a bloody good photo too Im going to up the clock speed on mine to what you said and get this speedo run up finished today : )
  9. Hell, I go away for a day and change a steering box and we make some right progress. Would be real good if we could make something to talk to the 3 pin port on the back to avoid opening the case. I manage with this electronics stuff but dont get a great deal of time to use it. Id be interested in making a micro controller based LCD display / button arrangement to type a new mileage in to adjust the mileage from out side the case but have no idea how that port works. Great work, today we have covered some ground..... : )
  10. I think it maybe glued. The 3 pin programming port is at the bottom of the rectangular hole above the RH bulb holder in my photo. looks like 3 pcb header pins soldered to some wire and poked down the hole would work That would be most helpfull, although i guess its already on your tech post about fitting the new style instruments, i dont mind looking over that again... but for others who stumble upon this post it would be good
  11. Probably, however land rover got VDO to implement afew other features to solve a few niggles for TD5 models. These were a fuel guage damper circuit which also drives the low fuel warning lamp. So no more fuel light at half a tank on a roundabout I believe there is some cirucit in there to read the temp sender from a 300tdi and control the td5 style temp guage.... but iv not got that far yet. also it contains an alarm warning LED which i would also like to use on mine to save drilling holes in my new binnacle. Im not sure if this needs 12v or what and i dont know what voltage my current alarm LED is running at. More to come on this when i finally get round to it.
  12. Dont let the three torx head screws in the back fool you. These things just dont fall apart. I did remove them. but couldnt get the back cover to move. didnt want to risk breaking mine so went the long way and hence the run up circuit. A photo of the back cover. there is a seam right around the edge suggesting that the back cover comes away.
  13. In my program to make it run faster you would adjust the value in the brackets in the "delay_ms()" lines. cant drop them much lower but if you needed more pulses per second mikrobasic has a delay_us() command which stands for microsecond. there are 1000 microseconds in a millisecond. could be worth a try. Going back to the TD5 Speedo. I dont know the max pulses it can handle per second. If anyone can flash a pic chip i have a hex file you can use with the above program. We aint allowed to upload .hex files so i would have to email it out very good point for programmable VDO or the like. What you were saying about the eeprom, on the back of the TD5 unit there is a well recessed 3pin port which i am guessing is the program port. However i wouldnt like to tamper with that because i dont know how its wired and i cant talk eeprom. It would be nice to undertake correcting the mileage ourselves the quick way... but then i suppose we risk never buying a genuine mileage TD5 in the near future. haha.
  14. Above; circuit on tripad board with some link wires etc Speedo running at 120mph+ been going afew days now much quieter then a drill.
