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 for E30+ cars. 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) Purchase EK1Lite from sxth and use it to read the bin from your ECU
2) Follow the process with Sxth to "patch" your bin
3) Email your patched factory bin to [email protected] along with a list of mods and fuel being used
4) We will work with sxth to ensure we have the correct definition file for your bin (e.g. may be a delay at this step if we don't)
5) We tune the bin and email it back in ekp format along with a factory ekp for the car for when you want to flash back to stock.
6) You flash the tuned ekp to your car with the EK1Lite device
It's a little more complex than say BMW flash map distribution as there is some labor involved and I imagine some waiting involved as sxth builds up their bin definition files. Due to the labor we'll have a small labor charge. We're going with $75 to start and then we'll evaluate it from there depending on how much time it actually ends up taking on our end. paypal to [email protected] when you send in your patched BIN.
I have not played around with any of the "exhaust burble" maps yet personally but those will also be an option, as well as raising the speed limiter for those who have upgraded their tires, etc. As is our company wide policy we will not disable any emissions equipment for you so don't even ask.
I'll update everyone when we've made a little more progress!
