Probably none if youíre keeping the same settings, are already happy and donít have issues. If you want to go higher it may help. No software fuel limiter, for one. It might let you go above that additive level.

You are asking generally difficult questions because it's hard to compare that way.

There are 5 BEFs, right? A stock, E85, E85+meth, Race, and Race+meth

Race gas is high-octane fuel. It's probably the overall best thing you can use, but it's super expensive, so few people use it. Instead we use ethanol or methanol or both. And there are BEFs for those options as well.

So, if you're stock and are on 91 octane fuel, you'd better use the stock BEF. If you're going to use an MHD map instead, you'll see that there are stage 1 and and stage 2 91 octane options.

"Stages" seem to be used by the industry to designate hardware/bolt-on modification levels and therefore are somewhat orthogonal to fuel choice. JB4 handles the "stage" selection mainly by map selection. Stage 2 is typically for high-flo catalaytic converters or c4tl3ss d0wnp1pes plus maybe an intake upgrade.

So pick the BEF type that mostly matches your fuel, and then set the JB4 to a map most closely resembling your hardware.

Or, same thing for an MHD map. Pick either stage or stage 2 to match your mods, and then look at the various fueling options for each stage that they have. For example, MHD stage 2 has an ethanol variant, as well as a 91 octane, 93 octane, and 95 octane variants as well. Stage 1 has similar options.

This is why you can't just straight up compare a JB4 BEF to an MHD stage 1 or stage 2 map.

MHD has come up with a new better way for us to disable various nuisance fault codes. Should be in their next app release and we have the corresponding JB4 BEF maps here ready to go when they do.

Ok i understand what you are talking about,i was only asking as i am already currently using jb4 set at 5.5 psi flat and using the RACE bef map with a c4tl3ss d0wnp1pe on shell v power 99 octane (uk) fuel i was just curious if id see any improvements going to the mhd stage 2 map or not.

im guessing that i wouldnt see any improvments as im already running into limitations from the fuel therefore needing meth or another way to boost octane to see any more gains in my case.

You might notice other things with the MHD maps because they are flash tunes. Like how smooth it is, or that more power is available without going WOT. But let’s say you switch to MHD Stage 2 93 / 99 - you’re going to get better advance but probably less boost than a JB4. Depends on what you’re after. If it’s winning races, or dropping your 1/4 mile time, you may simply want to maximize fuel and power.

Per Terry, the correct file is actually RACE on 91 octane.

Good to know, wonder what the b58 STOCK is for then. The name is misleading.

For the WhasApp group drop an email to MHD.tuning@gmail.com as they are the admins and can share a working link. Tell them you want the JB4 thread.

Agreed... it was a bit confusing.
By the way, are you running the ewg wires on the b58 by chance?
I'm buying it soon but worried the wires aren't long enough to reach the drivers side.

I used to. They help with controlling boost at higher levels esp with meth or map 6. Took them out because I’m running MHD stage 2/e30 atm

Perfect and much appreciated. I think I will wait for awhile until more info appears. I would love to have more info on level of improvement on JB4 using the MHD. Apples to apples comparison.

So far, I am picking up 5-10 % over the JB4 for the same map settings.

We will see.

Thank you for your response.

Not long enough. I had to move my JB4 to the passenger side. Even then, it was a tight fit for everything to reach.

Thank you for your response.

Wait, can you clarify? What did you do that is giving you 5-10% over the JB4? Or do you mean that is what youíre deducing from othersí experiences?

I am basing on it some of Terryís comments. See page 8. Not sure how to copy it here.

The argument appears to be improved timing. That makes sense to me.

When I optimized map 6 flat, timing is the key, not boost.

will there be other changes to the updated maps to improve performance or is it just to keep up to date with MHD.

We have JB4 and MHD maps for it ready to go, running on a couple cars already. Just email me once it's installed and I can send over what you need.

Always little changes but fixing the fault code deletion of annoyance faults no longer needed when running an aftermarket flash was the top priority.

I dont use BEF, and I'm running Vrsf catls, BMS CAI, JB4 Map3 v13.

Also, I dynoed on map2 on mustang with 340whp and 363 lbs.

This is the BEF thread but sounds fine for an MD dyno, those are not normally useful for internet comparisons but great for tuning on.

Hi guys...is there a reason why I am unable to clear codes on the jb4? Is there a setting that needs to be checked. It allows me to read but doesn't delete them...
