MS43 330i Supercharger

Postby Renovelo » Fri Jun 15, 2018 11:03 pm

Here is a customer's tune for a supercharged 330i.

Specs:
  • Supercharger: unknown model but it looks like an AA kit
  • Injectors: Lucas/Delphi #D3165BA
  • MAF: stock
  • Headers
  • Full exhaust
Injector notes: From our other research, the 330i comes with ~24.3lb/hr injectors stock. Here, ~40lb/hr injectors were used. This equates to an injector scalar of 24.3/40 = 0.6075 which is very close to the scalar we actually used in this tune.

Final power/torque:
  • 289 whp
  • 268 ft-lb
Note: this was the customer's final tune. If you use this as your base tune, you might want to remove some timing to be safe until you can finalize everything on a dyno.

Sorry about that! All attachments should be fixed now. We recently moved our entire site to a new server and had issues when transferring the attachments.

Must be a Rotrex C38-81 supercharger!

Interested to see this is running a stock MAF. My 330i SC appears to be maxing out on the MAF, so looking at MAF scaling will be useful

Yes, this customer was using the stock MAF sensor. From what I remember, the logs showed that the sensor was reaching it’s max value after the redline was increased slightly. Since it was so close and happened right at redline, we left it alone. If your setup is flowing considerably more air, then you’ll have to use a special version of the firmware we developed where the MAF sensor range is doubled. Email us for more info since I don’t think we’ve published this tune for MS43 yet (only MS42 has been published).

Hopefully this fixes my issue with my car, I had the AA can tune that came with the kit and ran fine for a few weeks and then stopped pulling, I've replaced almost ever sensor and tried many different things including a custom tune except it keeps pulling timing even thou there is no knock, Even tried sunoco 116 today just for testing and made no difference.

Hello, could I use this map with retarded timing and adjusted fuel maps, for a different supercharger, I have eaton m62 and plan on putting it on m54b30 in bmw e30?

Sure, you could use this as a starting point for any forced induction build. Be sure to note the injectors used in this example along with the fact a stock MAF was used. You’ll have to make the appropriate changes to your fueling if you’re not using the exact same injectors. If you’re using a larger MAF, you’ll have to account for that too. We can’t tell you how to tune ignition as this can really only be done using a chassis dyno. For that matter, the majority of your tuning should be done on a dyno.
