  1. I have to check in datalogs if the cut% stays the same even if 0bis detected durung shift. Settings really depend on power level and engine. I don't use 40drg retard on all cars. If 10deg works for your application, leave it. Back to fuel &ign cut. Shifting out of gear will be faster, if ign cimut is appkied instant, rather than waiting for next inj. event.
  2. Sorry I've forgot about this thread. I got similary expierience as Vtrsp1. Even with 15% fuel enrichment, i can not prevent big bangs (and following overboost) in all situation. So the only solution seams to be fuel cut. I'm using 60-85% cut depending on gear an up to 40 deg retard. Adam I was hopping that the cut is faster with the use of ign+fuel cut, but now I've read your explaination, there wouldn't be any difference. That gear 0 is detected between shifts is a bit strange regarding gear dependant settings. As I mentioned above I use different cut leveles based on gear. Now if it is detecting zero for some time, it takes gear 0 cut mid shift. I think there should be abother status integrated "betweeen gears", so gear cut level of the gear shifted out is used for the whole shift process.
  3. I like to start a thread where everyone can add his Math channels, so a database is built. Please only post Math channels with short explanation in this thread. To keep it simple any discussion must be done in other threads. Boost error channel = Target Boost - MAP Boost error parameter can then be used to control an electric Blowoff Brake bias = (rear+ front break press)/ rear break press Front Wheelspeed Difference = LF wheel speed - RF wheel speed Used to tune your LSD differential settings Slip right = nondriven-wheelspeed - RR wheelspeed Setup an Aux and turn on a driver warning light on the right side of the dash. So Driver knows right rear wheel is spinning faster ( eg. attention after a curb). Add the same function another for left. Then it looks like this :-) from 3.00min Boost error channel = Target Boost - MAP Boost error parameter can then be used to control an electric Blowoff Brake bias = (rear+ front break press)/ rear break press Front Wheelspeed Difference = LF wheel speed - RF wheel speed Used to tune your LSD differential settings Slip right = non-wheelspeed - RR wheelspeed Setup an Aux and turn on a driver warning light on the right side of the dash. So Driver knows right rear wheel is spinning faster ( eg. Attention after a curb) to another function for left.

    Math Equation

    You can use the generated math channel as: - logging channel - input for other function - axis option on tables So it's up to your creativity what you can do. Combined with Virtual Aux and timers the possibilies are near endless! A few example: Boost error channel = Target Boost - MAP Boost error parameter can then be used to control an electric Blowoff Brake bias = (rear+ front break press)/ rear break press Front Wheelspeed Difference = LF wheel speed - RF wheel speed Used to tune your LSD differential settings Slip right = non-wheelspeed - RR wheelspeed Setup an Aux and turn on a driver warning light on the right side of the dash.

  5. I agree ETC table should allow also negative corrections, for "quick and dirty" adjustments. Sometimes you can tune charge temp correction perfect for normal operation temps (60-110 degree coolant temp and 0-80deg IAT) and when you finished with the whole tune, you see next day that the cold start is to rich. Means you need negative ECT trims.
  6. Even better would be to make a General adusment function for different tires. For example setup a WET switch in the car, which switches tire diameter, rain light, DBW Map etc.

    Torque managment

    Hi Simon Why not unlock the function for use with all ECU's? A torque ctrl function will be good for WOT and partload.
  8. Yes thats a good suggestion. Even better would be a propper fuel film modell or at least some kind of short and long term acceleration enrichment.

    More Virtual I/O

    Do you use the lates firmware? It has 9 VA, if I remeber right. Or is rhus still to less for your application?
  10. I'm using fuel cut most of the time to prevent the very hard bangs during shifting. But the downside is, the power cut feels a bit slower. I would really like if LINK will do a IGN And Fuel cut option.
  11. I like to add another point. I'm really missing a delta function where you have two cursors to see the difference between two points. Once GPS mapping is possible a distance mode for the X-axis will be needed, too.
  12. Hi It would be great if you can share you results, regarding high pressure pump, trigger pattern and injector charakterisation. Thanks.
  13. You can span one axis of the target boost table to a rotary switch, so you can do up to 33 different boosst tagets. If you use a potentiometer you even can get infinity many boost targets.
  14. Sorry if i hijack tjr thread. Why is ign and fuel cut used for rotary and why not also on other engines?

    Co2 boost control

    Please elaborate what you want to achive. Maybe its already possible.
