New owner/ JB4 maps E30?

[StingerKMA]

New to the stinger forum not to the stinger world. Been working for a Korean car company for 10 years now and I just purchased a 2019 GT2 rwd. Already installed intakes and agency power bovs. Ordered a Jb4 along with step 1 plugs and a diff brace. What's a good map to start with on e30 when I eventually mix. I heard map 3 and some say 5 with E30. Eventually going to install cpi kit into stock IC until I pull the trigger on a BMS fmic. Thanks in advance.

Welcome aboard! And thank you for signing up. I'm glad you found it. Congratulations on your new Stinger GT! What did the Stinger replace for you?

Also noting that I'm moving to topic out of the community lounge and into the Stinger JB4 forum.

The maps are designed around common octane limits, so generally it's Map 1 for 91, Map 2 for 93, Map 3/4 for E30, and Map 5 for "race gas" (but some people's cars handle it fine on E30).

But different cars react differently so it's really a good idea to work you way up through the maps, learning to read the logs along the way and confirming you aren't having any issues. Plus you get to incrementally enjoy each upgrade.

Good to know. Is there any real benefit with the ewg wires? I'm sure I can tap into the oe wires and install a terminal into JB4 if I really needed to down the road. I heard they'd only benefit from a BEF? Is this correct?

EWG wires are typically used to solve overboosting (by opening the wastegates sooner/faster). They could improve performance by reducing underboost (by closing the wastegates faster to build boost more quickly), but bigger gains would come from getting "fuel wires" (O2 sensor connectors) that let the JB4 lean things out higher in the rev range.

That's why fuel wires are recommended as a performance upgrade, while (from what I've seen) EWGs are more as-needed if you have overboost problems.

BMS sells connectors that go in between the OEM harness and sensors, so you can tap into those connectors instead of piercing the car's harness.
