    Lean Spikes Between WOT Shifts

    True. I worded it incorrectly.

    Lean Spikes Between WOT Shifts

    Reviewing data and I am noticing minor lean spikes between WOT shifts. It's probably not something to worry about very much but I would like to see if I can make it a little better. What area would I make adjustments to first? Wake up load correction table?

    flamethrower tune help

    In the Motorsport Anti Lag setup I believe. Lots of fuel and retarded ignition timing.

    Misfire issues?

    I am going to say it has something to do with the fuel table values differing so much in that one area. Someone correct me though, I am still learning. You can see the INJ PW jumping around because of this.

    Closed Loop Over Boosting

    Closed Loop Over Boosting

    I changed stage 2 ON from 30 to 50kpa and logged the run. Still doesn't show stage 1 to be active. I didn't get to adjust WG duty as the day ran short due to a flat tire. nov11 01.llg

    Rich spike on throttle change

    Following this. I having a similar issue where it goes rich for a moment after stabbing the throttle. I found adjusting the accel hold to 2 INJ events helped my engine setup. Try some adjustments on the accel sense and decay? I'm going to try adjustments in the clamp table this week, starting with lower rpm first so I don't possibly run into a lean spike during full throttle gear shifts.

    Closed Loop Over Boosting

    Okay, now it makes sense. I'm not sure how my tuner went about doing it. What area of the table should I address some attention?

    Closed Loop Over Boosting

    Here is a longer pull that I logged a few days ago. Okay, if I understand correctly then perhaps try a stage 2 setting of 15kpa to start? pull 2.llg

    Closed Loop Over Boosting

    I am looking into fine tuning the boost control. I am reading the help files to get a better understanding on how closed loop control and PDI works. Have a look at my log and give me an idea what area I could look into for adjustments. I can see that my boost integral (%DC) goes into (-). Whats happening exactly here? now.llg

    ECT Sensor Calibration

    Rb25. I have selected the correct sensor calibration but it reads roughly roughly 15 degrees different from my aftermarket Defi gauge. I have my Defi sensor located in the block between cylinder 5&6. My factory sensor is located in the intake manifold right at the water neck outlet. What would be the best sensor location for this type of engine? (RBs are known to run warmer at the rear). If the block sensor reading is best, how would I go about setting up a table to suit?

    Lean warm/hot restart

    Funny, I am having the same issue. Would like to hear what others have to say. Good read here in regards to same problem.

    Fuel Table Cell Numbers

    How important is it to get the fuel table cell numbers close to 50 in the middle of the table as stated in the help files? I have not gotten that far into the table yet without a proper dyno and knock gear, but with the rate I am going my numbers seem to be around the 30's, low 40's in the middle. What would be my next approach to get these values a little higher? Perhaps start by changing my Master fuel from 8ms down to 6ms and do the correct calculation on the fuel table to bring my AFR's back into target? I also need a little better explanation on what the master fuel trim % does? Mine is currently set to 0%. I can't quite grasp the understanding that the help file information is giving me.

    VCT Setup - GP Output

    How do you guys like to set up the VCT trigger on an RB25? I was recommended this way as shown. The car runs great so far, I have some good street miles on it with very minimal issues. I find the way its currently setup its switching on and off lots with light cruising because of the (AND 3) switch condition. Perhaps just try a few other switch conditions and see what the car likes best?
