Someone told me that if I wanted to go Meth, I can consider running both Cobb and JB4+, letting Cobb run stage2+FMIC and the JB4 to run the meth. Is that possible? :S

[Wedge1967]

You can, but if you really want control of your meth, get the Aquamist HFS-4 Injection System.

[bigdnno98]

+1 most cobb users that run meth use the HFS-4 kit. The JB4 with BMS backend flash (loaded with Cobb AP) is an option but mostly for high concentration e85 users + meth or ugraded turbo guys.

Dzenno is running this setup. He has a DIY in one of the other forums.

He ditched the JB4 and is running strictly hfs4.

[cn555ic]

Oh. I see. But he still has his DIY if others want this setup on the other forums.

BMS offers a flash map that is used in conjunction with the JB4 to enable additional fueling, VANOS changes, and more advanced timing curves, when appropriate. It's not a Cobb tune per say but rather a map BMS has designed using the Cobb Pro Tuning suite that is loaded using a Cobb AP. You would continue to use the JB4 in basically the same way with regard to mapping, settings, in dash features, etc. For example meth on map 3 with a variable additive.

The new G5 ISO boost control combined with the BMS flash map is pretty impressive stuff. I can't wait until more on here are running it.

Most people running G5 ISO with backend flash hang out on the other forum

[slostjoe]

I just ordered my Cobb BMS Flash. I already have FBO, JB4 G5 ISO also. Can't wait!

[marv85]

You can but there is no real gain out of it if you plan to maximize your setup since stage2+ agg has relatively conservative timing.

If you want to run COBB and make use of a protune then get the HFS4.

if not, just stick with BMS and their meth kit.

However If you will run the BMS flash (which needs COBB) then I don;t see why not run COBB. There is no need to overly complicate the setup...

Running Stock Snails, prob not since you'll have a lot going on at once. The JB4 might outshine the COBB by itself when you upgrade the turbos since it's a little better with Boost Controlling.

DON'T quote me on this since I'm still running Stockers (with NO intention of upgrading)

The isolated boost control provides superior absolute (rather than load based) targeting along with a host of features. The JB4+bms flash is going to be a lot more enjoyable than a cobb map alone.

You could consider it but it is not the only option.

The idea was that Cobb Stage 2+ doesn't run enough boost alone to take full advantage of methanol, so you run JB4 to add a little extra boost and fuel along with it's inputs to safely run a a failsafe/flow sensor. The reason people weren't stacking a Procede was because of the cost.

You could also just tune your Cobb via ATR or Protune and use a different methanol kit, like HFS-4 (seems to be popular).

The reality is if your going to run JB4, you mine as well just run the JB4 alone with methanol, i dont see why it is so necessary to stack tunes. I would go with the new G5 board though, especially if going upgraded turbo's.

It should probably go without saying you may want to consider the PROcede it's also more then capable.

The stacking of Jb4 was popular before ATR and PRO tune were available with Cobb.

I've nothing but great things about the JB4 ISO and Cobb stack. Go for it.

This.
Without a means of adjusting the tune to take advantage of meth OTS Cobb maps just weren't aggressive enough. So people were using the JB4 to throw more boost at it.

Now that ATR/PROtunes are readily available just get an HFS3/4 and let Cobb run the show.

[neilvosko]

ya, i have the G5 iso and looking to add Meth so was considering the BMS flash, but my car hates e85

[Knifemundo]

Do you need th G5 boards for the backend flash? Can you use the G4 board?

You need to stack if you're:

1. Running RBs with 6AT and want more than 1.28 bar peak boost (18.6 psi) or run out of fuel
2. Flatline on 6AT
3. Run high concentrations of E85
4. Run a non Aquamist methanol kit

And the reason stacking Procede isn't as popular is because you need to modify the harness and Vishnu doesn't support or condone it unless its their own flash.

I'm not a huge proponent of stacking either but I am out of necessity.

It hates E85 because you're probably maxing out your trims. Getting a base flash would help you in that regard.

I don't feel the flash is necessary if you are running pump+meth on stock turbos though.

I just realized I am responding to a very old thread. I fail.

this is NOT true

Me too to correct you
