[Terry @ BMS]

I got the software up and running and so far it works as advertised. Maps I've loaded function exactly as they do under the BB & Cobb environment. Only, with a little more flexibility than than we have via the free environment.

I initially was not thrilled with the licensing model but now that I've had a few days to think about it I've realized MHD will need to provide some level of support for this. So while charge per VIN wouldn't be how I'd structure pricing I can respect the model.

I'll discuss working out a special price for BMS customers who are only using this system to load JB4 back end flash maps. Maybe the system can send a ping out and the JB4 respond via CANbus to enable that special license. And for those who want to do their own tuning the existing pricing model seems reasonable compared to what Cobb charges. For those using the BB software currently we'll continue to support & develop those maps as free open source options.

With the MHD flasher are u able to just load the current BB back end flashes?

[Terry @ BMS]

The current BB flash maps can be loaded directly.

For those who run > 18psi, the race logic in this system will allow us to produce an improved version of the back end flash maps specifically for higher boost levels. I'm starting to work on that now. So far no issues having the flash map observe up to 20psi. If anyone is testing out the MHD stuff in a JB4 back end flash map format drop me an email.

I'am.

Question about the bolded part

Will the revisions to the back end flash maps, such as 22psi boost limit and increased torque monitor limits be able to flash thru the BT cable with the BB software?
OR
Will one have to purchase the $99 flasher module + $69 Monitor module + android device and various cables?

It's a unique basically closed flash platform, similar to Cobb. Each car flashed has to have a VIN license. In terms of what a JB4 owner will need to purchase to load one of these maps via their system, I don't know yet. I'm trying to work out special pricing with MHD for JB4 owners who want to load our high load back end flash maps. You can't load a high load map designed for the MHD system via the free software. But we'll maintain normal load versions of all back end flash maps for those of us using the free flash tool.

I understand,

I will be very interested in back end flash maps for the JB4 via MHD, I’ll be ok buying their modules and can borrow my dad’s Galaxy S5. However if there is a price for each map (pump, race, E85) it will be hard to justify the cost especially on stock turbos where the gains are marginal (at least from the descriptions and features listed)

Keep us updated, I hope everything works out!

Backend maps are free. They have always been free.

Regular maps yes, but what about maps via MHD flashing modules?

if free perfect!

MHD supports both free and paid maps so you can pick what you want.

Actually for back ends you don't need the logger module.

Terry, Trebila don't you think current backends can be improved due to the modifiable torque tables, even when targeting no more than 18 PSI?

my MHD backend I'm developping since a week is already heavily modified, compared to the BB backend.

if all that's needed is a flasher module and a cable I'm on board

Nice log, good timing recovery!

The JB4 back end flash maps have always been free and will continue to be free. You'll just need a license from MHD to flash via that system.

It's difficult to say. It certainly can't hurt, and I think the low throttle mapping changes we can do with the torque monitor set to 1.0 will be an improvement. But the biggest issue facing flash tuning in general I think is false knock. For some reason when reshaping the load curve seen by the DME curves that drop load more aggressively to redline have less instances of timing drops post shift than curves that hold load to redline. Despite boost, timing, AFR, VANOS, etc, being unchanged in those areas. So this causes us to run wonky load targets like 200 tapering to 130 at redline to avoid timing drops. Which in turn leads to more work on the tuning end to make curves like that work. Part of that work is spoofing torque up as a function of load so the trans will shift well. But if we could eliminate the root issue then things could be a lot cleaner on the flash end.

I would love to have special price for MHD flasher, for BMS backend flash

any news about it?
I dont plan to go beyond BMS

[Terry @ BMS]

On timing, for example, here are two runs with similar boost curves. Both running 10psi off a WG spring on 100% E85. Actual boost reported back to the DME is the same in both logs and neither log gets up to the DME load target.

One has an internal load target of 200 all across, the other 200 tapering to 135 at redline. The one with the taper has normal timing while the one with 200 all across has massive timing issues including post shift drops. Why load target effects the timing behavior even when not running boost anywhere near that target continues to baffle me.

[Levan-i]

i definitely want to became beta tester
what do i need to do?

Oh, I would be all over this. Looking forward to the backends being available.

Hi Terry. Which table are you referring to exactly?

[Terry @ BMS]

If you email me I can reply with the current IJE0S single turbo file I'm testing.

[ShocknAwe]

So, I understand this is in beta testing, can we get a flasher module? Or do us that are wanting to use JB4/backend have to wait until release.
