Hey guys,
Been playing around with the flashing system for a couple weeks now and overall it's pretty impressive! It lets you load flash maps (and updates!) at home without having to ship and mail around your ECU.
We've got a pretty solid JB4 back end flash map developed now. Changes include revised air/fuel targets and scalar mapping for more consistent fueling, rescaling some annoyance limp mode limiters like turbine speed or boost too high, revised calculated torque for improved shifting, and of course bumping up ignition advance for more power. With the BEF loaded you continue to use the JB4 maps as normal for determining how aggressive you want to run, boost by gear changes, etc.
We're also working on a BEF for use with straight E85 which has proven more challenging than expected. Fortunately SXTH has been really helpful in adding tables as we ask for them to keep it moving forward. For example we had to make cranking fuel changes so the car would start properly on cold mornings, spark dwell changes to prevent spark blowout at higher RPM, etc, etc. There are still a few things to work out but progress is being made! Note to run more than around E40 requires the Fuel-IT high pressure pump, CPI, or WMI.
One of the differences between the way we do flash maps and what some other tuners do is that we're fully transparent about what table changes are made. We're not trying to keep any of the flash changes secret. For example attached are the current cranking and dwell changes we're testing on straight E85.
The next step is to expand customer testing. The process is:
1) Order your EK1Lite here: https://burgertuning.com/collections...ducts/ek1-lite
2) Follow the process with SXTH to "patch" your bin.
3) Email your EKP serial, last six of VIN, and Calibration ID to [email protected] along with a list of mods and fuel being used.
For example:
EKP serial: EKL322410521.
Last six of VIN: 123456.
Calibration ID: IKKN3TMW_F0C
Mods: Intake, muffler delete, CPI
Fuel: Looking to run as much E85 as possible, 93 octane only, etc
Burble: We can do a light exhaust burble, indicate if you want it.
4) We will work with SXTH to ensure we have the correct definition file for your calibration ID, expect a delay at this step if we don't.
5) We will do the tune and host it on SXTHs portal (if its not already there!)
6) You copy the tuned EKP to the SD card and flash the tuned EKP to your car with the EK1Lite device. Note you can also download factory maps off SXTHs website for when you want to flash back to factory.
Our BEF maps are $75 each. We're working on migrating maps in to the SXTH map portal for distribution in which case payment is made via their website. Alternatively we will have you paypal [email protected] if the map isn't yet hosted.
Note as is our company wide policy we will not/can not disable any emissions equipment for you so don't even ask.
JB4 BEF Standard Options:
RACE: Ignition advance set to around 17 degrees peak, AFR around 11.9:1 at peak HP, suggested for those running good quality 93 octane up through 30% E85. Typically cars that are not running CPI.
RACE_IGN: Similar to RACE but ignition advance has been raised to 21 degrees peak, suitable for aggressive WMI applications running 93-E30.
E85: Ignition advance set for around 21 degrees peak, AFR around 12.4:1 at peak HP, suggested for those running E40-E60 mixtures. For higher boost JB4 maps CPI, WMI, or HPFP are required.
PUMP: Mild timing changes, AFR set to around 11.9:1, suitable for 91 octane and lower grade fuels (I'm looking at you Canadian 94) where timing corrections are an issue.
All can be done with or without mild exhaust burble.
JB4 Settings Once Flashed:
1) Turn on option 0 to disable JB4 fuel biasing (since AFR targets are set in BEF now)
2) Turn all other options off, including option6 which is only used for non-BMS BEF maps that run higher boost targets
3) JB4 maps will operate as before, pick the map based on how aggressive you're looking to run. We suggest starting with a lower map like map2 after flashing to evaluate and ensure everything is working properly. And you're welcome to email in a log post flash if you want me to check it out.
