  1. Can't tell if that's the right cable or not. I always look for some reference to Triumph motorcycles, like this: But assuming you do have the right cable, you need to make sure you have hooked up all the ecu power and ground wires, and no loose connections. Just hooking up one or two of them isn't going to do it. Use similar gauge wire that's in the car too.
  2. Wait, what? VS was down?! Who did the re-solder? I've had to do mine multiple times now. You've got to clean off ALL the old solder first, or it will just break again (ask me how I know.. ). Look at the solder joints with a magnifier; you'll see the cracks if you look carefully. Or @Matty Moo could take care of you too:

    That bites big bananas!! Seeing Marlon cry makes me sad too..
  4. Not common AFAIK. What's entailed in "flashed ECUs"? Do you have anyone's mods incorporated?
  5. Good stuff! You could add instructions on how to use these channels here and on the wiki too. Yeah, a bit sad, but it's up to the rest of us to keep it going, as best we can..
  6. Interesting? I generally agree there may be ambiguous info at places in this thread (as it is wide open after all) but the standard channels that have been known to work for some time are the tank pressure and the rear O2 sensor inputs. The thing about the latter is to NOT use the rear O2 reference (ground) pin of A19 since this will cause an offset; use A18 or other known good ground reference pin instead. Has someone said the accelerometer input works for logging? Don't recall hearing about it. Not too surprised if there's some signal conditioning circuitry in there for that channel.
  7. Thanks for the reminder; every once in awhile I actually think about getting back into it (on part-time basis). It's more fun as a hobby than a business I suppose..
  8. Seems a zener would be a more appropriate solution, no? Thinking two zener diodes back to back (maybe a resistor in between) across the VR sensor leads?
  9. Awesome results! Wasn't sure what you meant by "synch loss" but then found this link: Now I see. Good shielding on the VR sensor?
  10. @black855r I'm assuming you're going for AFR readout for petrol fuel. So looks like the 30-0300 AEM gauge has the same transfer function as mine, which is AFR = 2.375 * volts + 7.3125 // note the output units here are AFR, except for the 2nd term (2.375) which, if you think about it, is in AFR/volts (AFR per volts) units. As my old algebra teacher used to emphasize, it's very important to understand what your units are in an equation. So we need to figure out how to convert that 2.375 term above into something the ecu understands, since we're hooking up the output voltage from the AFR sensor to an A/D (analog to digital) convertor in the ecu (aka the tank sensor gauge input) which we happen know is an 8bit convertor so it has a numeric output range of 0-255 bits. Then to convert the AFR/volts term to AFR/bit, we need to multiply it by a term in units of volts/bit. That term is 5v/256bits, which is the voltage span of the A/D divided by the bit output span (i.e. 2^8 = 256). ==> 2.375 AFR/volts * 5volts/256bits = 0.0464 in units of AFR/bit (rounded to 3 significant digits). AFR = 0.0464 * x (in bits) + 7.3125
  11. Help us help you. You'll need the analog output conversion table for this gauge which will be in the instruction manual. What's the AEM part number? Various manuals can be found here:
  12. Wait, what??!! It's more than weird, it's the friggin apocalypse!!
  13. Kind of boosted engines 101. It's why lots of people add bigger intercoolers. Do some googling on it; here's a decent explanation: So what does "supporting mods" mean exactly in your case?
  14. Nope; same message: "Sorry, there is a problem This attachment is not available. It may have been removed or the person who shared it may not have permission to share it to this location.
