Title: B58 MG1 torque/boost limiters? Post by: marchewa on February 27, 2025, 02:33:31 AM Hi, I'm not to experienced with mg1 B48/B58 ecus and I'm writing hoping for some guidance
I think I'm struggling with some kind of torque limiter (which was not present in previous MEVD based ecus) as I can't get more than 1 bar of boost and about 580Nm on dyno in 2,5-5krpm rpm range (see vehical log screenshot below) in two different cars. I attach ols project of one of them with defined changes (note that some safety maps are maxed for test purposes, this is not final version as I'm still searching for reasons of low boost). Too big file for attachment so uploaded it here: https://drive.google.com/file/d/1lcI2DzuatVWFKhmKuj0A0zg0DS9Xf3Rx/view?usp=sharing Tested two different cars (X3m USA market and M240i EU market) with similar results. One of them with XHP software with maxed torque limiters. I appreciate any help. BR Title: Re: B58 MG1 torque/boost limiters? Post by: h2esk on March 06, 2025, 06:50:10 AM Too low torque request?
