  1. The gain value is within the range I would expect it. I'm using similary values.
  2. No problem, just set tps lockout to max (110%) and Map lockout to something like 500kpa. I recommend to use link can lambda or internal on Furry and Thunder ECU, because they can dectwct wrong sensor which sets CL lambda to openloop. On analog lambda it could be possible that a wrong sensor leans mixture out.
  3. I tune near each week G4+ and G4X. Yes, I really feel what LINK claims. The faster ECU and asynch injection leads to better throttle response. On the g4+ you allways see a lean spike during fast throttel opening. On the G4X you won't see that. Idle stability is much better, too. And Maths are such a great tool!
  4. Sorry my fault. You have to do it the other way arround. Virtual Aux PWM Aux with condition VA PWM > 50% and turn off delay: 0.2sec But yes we have to wait for VA PWM update
  5. I would try to use an Virtual Aux with on condition Aux pwm > 50% And switch off time of 0.2sec or so This gives you a boolean including hysteresis.
  6. Just had the same situation yesterday, but luckly found it quickly. I also found that cylinder level turned off when i switched between first and second order filter (7 and 14khz). Then i had to switch to another second order filter and back to make it work again. Seams like a strange bug.

    Reading boost pressure

    The parameters you are looking for are MAP and MGP.
  8. why not using a VA aux to Switch ON and off? You can implement a logic with a Timer, start and reset timer with DI = ON and then VA only turns off if timer X < 15sec.
  9. If i remember right, numbers in Pwm table means: 0 % = 12V 100% = 0 V Means you have to flip your numbers in the table. You should check current requirements, too
  10. 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.
  11. 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.
  12. 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. 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.

    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. So Driver knows right rear wheel is spinning faster ( eg. Attention after a curb) to another function for left. Then it looks like this :-) from 3.00min
  14. 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.
  15. 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.
