Terry, didn't you learn a few things since then? I remember a thread where you found some maps that you didn't know about back then. Was that only for Cobb boost control? I can't remember exactly anymore.

That thread has the current back end flash info as it relates to OEM turbos for the N55.

So I'm thinking of reinstalling my JB4 but want some clarification on how I switch between different fuels.

eg.
If I have a Vargas turbo, shotgun hpfp and upgraded lpfp and want to run 100% e85 then could I potentially do it with the backend flash you provide?

Then if I had to run normal 98ron petrol do I have to switch flashes or would changing maps with the JB4 be enough?

We'd have to custom make a 100% E85 back end flash. Once the shotgun is installed do a log and throw it on the support section or email it in and we'll get to work on that.

If using 100% E85 map and going to pump you'd need to also change the flash map. The fuel scalars, timing advance, etc, would all be set wrong to use that flash with straight pump gas.

Terry, for those of us that can't get a back en flash, an additional injector can be an option? Maybe using the nitrous activation cable? For example: https://splitsec.com/product-categor...r-controllers/

I'm no expert, but I do remember that was the solution for fuel needs back in the days.

If I was able to pick up a cobb v2 used would that work for a back end flash?

why are you asking basically the same question again. Yes, if it has been unmarried from the previous owners car then you can install any flash you like with it.

Well I tried searching for the answer but I'm new to this platform and don't want to drop hundreds of dollars on a device that may not be compatible. Thank you for your help though.

Hi, Terry, I am thinking of going with the Vargas stage 1 in my FBO E92 N55. I understand that I will likely be able to carry 17psi (maybe more?) all the way to redline with that unit and the factory fuel system. Aside from setting a custom boost curve on map 6, will any of the maps compensate for this extra flow or are they all programmed to taper off quite a bit in the high revs like it does with the stock turbo?

In short, will I be able to capitalize on the extra air flow using any map other than 6?

Thanks for your time!

Not fully, no. Map 6 is pretty easy to set up. I am finishing up my Pure stage 1 install tonight.

Adding in the 3.5 bar TMAP sensor will enable the JB4 to hold more boost to redline on all maps.

Reaallllly...

So if I add the 3.5 bar TMAP sensor, I would be able to enjoy the flexibility of map 5 but with overall higher boost levels...i.e. no tapering up high?

Yes. Once equipped with the 3.5 bar the JB4 uses a different set of map targets.

Couple quick question for dct equipped equipped cars that can run the backend flash:

1. If I have a DCT car with PURE upgrade how do I apply more pressure to clamping pressure on clutch plates? does the base backend flash already do this for my application 98GOB?

2. For the stock fuel system, is E40-E60 fuel ok to log with for base suggested settings on custom map 6 with low targets like 16psi? If not, what would be the highest ethanol content that would be safe on the stock fuel system?

Thanks for the informative thread.

We've already increased it to the maximum with the current back end flash, at least what we believe to be the maximum. If slipping continues with the back end flash in place let us know and we can try reported torque even higher.

Thanks Terry. What ethanol mix do you recommend with the stock fuel system and stage 1 turbo? We have 91 octane in ca, would some e85 be required to bump up the octane a little bit?

You should be safe starting with E30 and most cars are ok with E40.

The BMS Cobb maps are in the first post. Load the appropriate one. Then use the JB4 as normal.

When you plug Cobb into obd port it will tell you what ecu version you have. For example mine was 98GOB. So write it down after it tells you your ecu version. Then go to the front page of this thread and download the attatched specific file for your ecu version into Cobb access port manager on your computer. Load that file into your Cobb unit then flash the car....

yea I am 98g0b. I have the map downloaded now and uploaded to my cobb. I will install cobb and back up ecu data while on jb4 map 0 then flash ecu with special map. then unhook cobb throw it in the glovebox and change back to desired jb4. Sound right?
