Advice on Race Gas map for Procede v4 Rev II - BMW 3-Series (E90 E92) Forum

So very close to my house I have access to 110 pump gas, just wondering with my setup (in my sig) what ignition correction and user torque settings should I use? I assume 0% ignition but what UT?

With regards to ignition torque I think any time you are running race gas you can run it at 0 regardless of other mods.

Assuming the 110 is leaded which I am sure it is, and based on your sig you dont have catless dp's you should not run leaded gas. Stick with 100 out of the pump. MS109 is the best though.

Agreed. Leaded might cost you your o2 sensors.

Because you don't have full bolt-on mods, you will need to try different stages and use the custom tuning guide to review your logs to tell what stage is best for you.

what would be the isssue with running leaded fuel with the cats? I plan on getting catless but havent done so yet. Why does it goes the 02's to go bad with cats vs catless?

I think it will destroy your o2 sensors. 1) o2 sensors are costly 2) They will throw all kinds of codes if they are damaged. I would wait until you are catless and use the procede o2 sim before running leaded fuel. VP109 is about 104 octane and should be plenty. If you want more throw in a meth kit.

The lead will destroy the material in the cats. They will become useless and cost about 1k to replace. Unless you dont care about your cats at all or your 02 sensors being replaced then run the leaded gas... I had to replace 2 o2 sensors from running leaded gas and they are not cheap. I switched to ms109 and went faster and havent had to replace a sensor since. This is with a fully catless exhaust as well.

What type of power would this setup possibly produce with MS109 unleaded, with my setup with the stock cats? 360 370whp?

Probably around 380whp if you run enough boost. If you are racing at the strip on MS109 (105 octane), I would run at least stage 3, and I would try stage 4, both set at 0% ign corr. You only need to adjust UT if you want to lower the boost from the target. If you are MT I'd expect you to trap ~113-114, AT 114-115. A cheaper alternative to ms109 is sunoco104. It is only 1 octane point less than ms109 (105-104) but is only 2/3 the price.
