I have never personally tuned an NC MX5 but this is my understanding of it. When you enable the AFR Override table, you can then set your AFR targets for when the car is in only in open loop to whatever you want and ignore the factory open loop AFR target tables. By default, the table is set to 14.7...

Trying to understand how this works, when my accelerator pedal position never seems to register above about 67% on my 2012 mazdaspeed3. Relative throttle position seems to cap out at 77%. How do you ever see a pedal position at 98% or more?? On Gen2 Mazdaspeed 3s the throttle generally maxes around...

I suppose if the supplier sent that, then that is what should be best. They are a bit higher than what I would've expected, especially 25-30 degrees by redline. What camshafts are they? But as I stated, the cam phaser physically can't advance past 35-36 degrees of VVT advance, so anything greater th...

I may be wrong, but I believe the VVT cam phaser maxes at around 35-36 degrees. Meaning you physically can't go more then the 35-36 degrees of VVT advance, which you saw. What does your VVT map look like? It shouldn't be set to 40 degrees across the board if that is what you are inferring. On natura...

It is possible to have a flat curve with load during WOT depending on your airflow, however I haven't seen this before on a set boost. Either way, best thing you can do is to provide a log and see what is happening with the car. On another note, there is no need to change your Volumetric Efficiency ...

Say as you wish, but I assure you I am aware of what I am doing. Quoting you and only quoting you, "I would not go above load 2.3 (pump gas) on these engines before 3500rpm. At 3500rpm upwards it's fine." Maybe English isn't first language, but from my understanding when you say 3500rpm up...

I'll get logs with that next time I'm out, unfortunately can't go for a drive at this current time. However I do have 2 logs, one which was driving with 100% wastegate and the other which was only running spring pressure at 0% wastegate. For some reason the forums doesn't upload anything I attach so...

I have recently installed a BNR S2 on my car but I'm having issues with boost control. Originally when installing and taking it for the first drive, I was seeing boost levels of 22-23psi+ (!!!), while wastegate pressure is only 1 BAR. Turns out one of the covers on the back of the turbo was partiall...

There is definitely someone who can explain this better than me but this is my understanding. Like you said load is basically how much torque the engine is producing. The reason the targeted load drops off above 5000rpm is due to the stock k04 not being able to reach higher loads (with the stock BCS...

Interesting about the load, you mean I can increase up to 2.4-2.5 or more as long as torque doesn’t have any unnecessary jumps.
