Need help using jb4 please!

Timdelacerna123 · 10-24-2014, 02:38 PM

I have an EB2 335i ewg 2014 that has a mppk, mpe, injen intake, jb4 and catless dp. I don't have the EWG INSTALLED BECAUSE IM WAITIMG FOR MY FF WIRES. Is it safe for me to run MAP 2 guys? Thank you so much for the info!

Bee Pee · 10-24-2014, 02:41 PM

Yes. I don't have EWG or FF wires and have used map2. Benefit over map 1 maybe limited.

Enjoy

Timdelacerna123 · 10-24-2014, 02:43 PM

Thanks man. Can I connect the ewg harness without the ff wires?

infinitigor · 11-03-2014, 01:50 PM

Damn you have a MPPK and JB4.

Yes, with catless DP you should be fine to run map 2.

Side point, I haven't followed the install instructions on cars with the EWG as I have pneumatic, but arent the EWG connections and Flex Fuel wires totally separate things? Pretty sure the FF wires are to enable you to run E85 fueling mixes.

Map 2 should be fine as long as you run 93 octane

TayF80 · 11-25-2014, 07:05 PM

but isnt it necessary to have the FF wires to run stage 2 on the JB4? If the FF wires aren't connected, does that mean no power and just stage 1? or no jb4 power what so ever?

Mike_L · 11-25-2014, 07:46 PM

FF wires and EWG wires are sold separately, however, you need to run the FF wires to run the EWG wires.

The wires that change it from a Stage 1 to a JB4 are the CAN and power wires and the new control box.

ilyabarankevich · 11-26-2014, 08:17 AM

So, you need to have FF and EWG all connected to get more bennifits from the Stage 2 Tune? Im new to JB4 and trying to learn it more when i have to install it in Febuary.

MPPK is a flash tune, no?
How would the JB4 react on map 5 with MPPK?

It can make more power with all the harnesses attached. Without all the harnesses, its limited to what it can do since it can't control the fueling or wastegate. It still has substantial gains, but not as big as they are with everything hooked up.

It is safe to run Map 2. Make sure that you are on the EWG firmware if your car uses EWG.
If you don't have the FF harness yet, don't plug in the EWG harness.

Yes, EWG and FF are separate thing. You can run with just FF harness, but not just EWG harness. In order to install EWG harness, MUST have FF harness also.

No. Stage 2 can be run without FF or EWG harnesses. Those 2 harnesses are currently still on testing phase. It is not fully released yet. But, based on the S55 M3/M4 setup, they called it Stage 3 setup when you have the EWG/FF harness plugged in.

No.

Factory = Stage 1 (MAP 1)
No FF or EWG wires = Stage 2 (MAP 2 Requires DP)
FF and EWG wires are = Stage 3 (Also Map 2? DP + the wires)

^^^^ Would you say this is accurate ^^^^

Different power output.

any one know power difference? Boost levels?

Jera_Jakerz · 11-28-2014, 04:20 AM

WTH?

OP: As mentioned you can run MAP 2 in your current setup without the extra wires and although it is recommended to use the EWG Firmware for EWG cars, it is not required. In fact I did not use that firmware until I had the EWG wires 1) lazyness 2) I did not get the start up fault common with the EWG firmware 3) BMS checked my JB4 logs and confirmed it was working as advertised.

"6) To use the EWG add on harness the FF add on harness is also required."

I am actually confused as to why, unless it has something to do with the software and data required to make the EWG usefull...Yes it makes it easier to only take a part the AMP. In fact I have a hard time believing it because Terry has mentioned multiple times that these cars are not responding well to E85 (yes I know there are other benefits of flex fuel like straight race gas).

Bee Pee · 11-28-2014, 07:58 AM

Jera,

IIRC, with EWG harness only connected allows higher boost. Without FF to help tweak AFR then there were examples of EWG harness cars going too lean ie AFR too high. Either OEM ECU inherent protection or JB4 falisafe would intervene, either by retarding ignition/boost and/or LIMP mode or by defaulting to bypass map.

FF wires allows some control over fueling which allowed AFR's to stay within workable limits at higher boost levels.

Thank you!

I suppose I am too weaksauce to raise boost or push it hard until I get the chargepipe replaced...its just sitting in my garage waiting...
