If you change those two tables reciprocally, they should offset each other in the fuel calc. The load calc does not appear to be affected by the VE table. the MAF skew should fix the load calc, and the VE skew should correct the fuel.

Maybe scale MAF down 15% and VE up 15 % See what reported load looks like and if AFRs are close. Or maybe the other way around? MAF up and VE down?

This issue appears to have been related to an engine with a displacement other than 2261cc. The load calculations are based on the engine displacement amongst other things. Without direct access to a car with an engine with non-standard displacement, it is hard to test this.

Modify the bcs dc base table downward slightly with a focus around 2500-3000 rpm where the boost will tend to spike on initial spool up.

We published a new tune today to demonstrate the new load axis scaling on G2 MS3. It is for a stock turbo with a CAI and a RP. It has the load axis scaled to 2.25 and a peak load around 2.3. Obviously, a HPFP upgrade is required.

The rear O2 sensor has minimal input on fuel trims. It is there to determine whether the primary cat is doing its job. When running catless, expect to get and mask the catalyst efficiency DTC. Also plan to adjust BCSDC base a bit as the turbo will spool sooner and spike a bit more on initial...

Grimmspeed solenoid in interrupt configuration requires 30% less duty cycle than stock. Use that as a starting point then fine tune from there.

This was a major effort. All of the relevant tables have had axis scaling enabled to allow load > 2.0 You can read more here: https://www.versatune.net/forum/viewtopic.php?f=1&t=4075&fbclid=IwAR1jjBfwJq3NvlK7UPPlX78XxzGEdHhZ-yYqbAEaVqCH1PA_BXd2b8N46rU

You need to put your MAP sensor values in 3 places in the tune under the sensor calibration section, then flash the tune. You also need to set the parameters in the dashboard for it to log correctly. If any of your multipliers are too large and are not accepted by Tune Editor, you can enable...

Would Justin be willing to share the unlocked tune with me so I can try to fix it? I made nearly 500awhp on my ms6 with VT. I don't know what the problem is with "big power and VT"

We have published crackle and pop tunes for MS3, MS6, and NC MX-5, This is my Gen2 daily with a crackle and pop tune on it. As always, you can order at https://www.versatuner.com

PIDs/s is dependent on the processor speed which is different for each generation. Newer Skyactiv ECUs consistently deliver 200 PIDs/s.

Logging rate is limited by the ECU software and hardware. These are very small embedded processors running a real-time OS that has to service a lot of interrupts on time every time to fire injectors and spark plugs. You can't delay firing a plug because someone wants to know the boost pressure...

Both of you are gen one platforms?

Does MAP correlate to Load? I'm wondering if it's a reported load issue, not an actual load issue.

What issues? It's hard to follow dozens of forums and Facebook groups.
