BM3 Custom Tuning help

[QTR FMS]

I’ll double check these
I also did get my car back, uploaded my updated tune without the psi limit and I hit the limp mode in 3rd. Limit it to 26psi again and I logged my car twice without the limp.

From the log, it seems you are hitting the end of injection limiter (RF Max 8) and the cylinder fill Limiter (131072).

You need to lower the values at the end of injection. You can make it 70 above 100 load.

And for the 131072 its basically a cylinder fill. It usually cause by overboosting or exceeding load, raise your load limiter and try to keep it 10% higher than your actual.

try the above changes then, make another log and it would be better to make longer full throttle log, in third from 2000rpm to 7000rpm if you dont have wheelspin issues. or otherwise 4000rpm to 7000rpm.

Edit: are you using OEM boost control or BM3 custom boost control feature.

Hopefully this is a better log

You still have 131072 code, which is closing the throttle down to 41%.

What are your Maximum Relative Filling Characteristic table values? and check if you are limited by other load limiter tables.

You might want to look at all load limiters, which I believe are 10 tables (some are already maxed out at 327%), and add 50 over stock values to get to 245% load. This should get you to 26psi more or less, and you can then fine tune it later based on your boost curve.

For load to torque, I only changed the last column from 200 to 300 and multiplied the values by 50%, this will make it easier to track limiters later.

You are also crashing your hpfp at 5000rpm and probably in the lower rpm, there are 4 rail pressure tables that look similar to the one below. Change the highlighted cells to 30MPA and then you can continue to fine tune the rail pressure as you continue to raise boost and adjust afr.

Your boost target is 25-23 psi, but the actual boost is 16 psi because your throttle is closing. This needs to be fixed before we try to raise the target further.
