*** MHD F+G-Series V1.48 - Added B58 GEN1 ST2+HPFP maps, updated maps to V3.1 ***

MHD Tuning · 04-30-2020, 08:35 AM

Todays update brings many new things to the B58 GEN1 platform.

We added our new ST2+HPFP maps, these maps require a upgraded fuel pump, you can either use the stock B58TU1 pump (Supra, Z4M40i, M340i...) - BMW OEM part number 13518631642 or a Dorch / XDI HPFP.

The power gain across the complete power band is pretty impressive and the performance numbers are simply incredible. At the moment we offer 95/102 and E30 variants, 91/95 and 93/98 variants are in beta testing. The B58 is a high compression engine, low quality fuel and high boost can cause issues and we always want to offer 100% safe and reliable maps, the ST2 maps already nearly maxes out those fuels, thats why we need some more time on testing the low quality fuels at high boost ST2+HPFP maps and then decide if results are good enough for a release.

We also updated all our B58 GEN1 maps to V3.1 with big improvements to the low end and overall drivability.

The top speed limiter is now fully deactivated on all B58 cars (294KPH before) and we applied some changes to the cooling options (better intake air cooling).

Performance results on B58 GEN1 ST2+HPFP E30 map from one of our beta testers (M140i XDrive 8AT):
1/4 Mile 10.72s @ 128MPH (B58 GEN1 stock turbo world record!)
100-200 KPH in 6.9s
0-100 KPH in 3.0s
0-60 MPH in 2.87s
Dynojet: 522HP / 743NM

Do you have a dyno for the prior version to 3.1 map update?

Currently running the Supra pump with E35 on the Stage 2+ 95oct map. While cruising on the highway had the following codes pop up:
- DME active codes -
118001 - Mixture control: mixture too lean.

- DME shadow (inactive) codes -
11CF30 - Mixture control: Multiple fault.

Reminds me of the tuner codes id get with JB4 on my 335i. Wondering if anyone else has gotten this with the new map.
