Too high on menu 12 will force boost over target which will then lead to funky throttle and/or fuel trim behavior depending on the JB4 version being used.

Half the time when we change something to improve it for customer A we make it worse for customer B. Although, I'm pretty happy with 26.6 currently.
I do both (tank and live). The economy reads high in the car by a bit, but its consistent. Can't cover up a 5mpg loss - it means 3 trips to work instead of 4 per tank. I have a straight flat bridge and set cruise control and play with it; feeling and reading. The issue I am at now is that I can find a good setting for cruise, but then tip in is bad and the wastegates are too open on accell (no punchiness, makes a different noise, requires more throttle. If I set for punchy throttle, I lose a ton of economy. Basically while two options (10 and 12) are great, they don't fix the heart of the problem which I the algorithm. Settings that trade off performance vs economy can work, but throw in rattle fix and there just isn't a good answer. The wastegates rattle from improper adjustment. As our cars age they will get more out of spec (mine need adjusting again). Eventually it makes more sense to just fix the problem rather then tanking economy or performance to cover. That's my $0.02.

Can someone PM me one of the ISOs from 17-19? Preferably closer to 19 since I think 17 had some weird tip in setting.

Terry,

Have you ever thought of setting menu 12 to a performance/economy versus rattle fix toggle and then having 10 be the adjustment within that wastegate logic?

Thanks!

Default confusion - 09-20-2013, 08:09 AM

I'm very confused as to what this latest ISO is doing. Terry, could you break down what this update is? For instance, do I have to change the FutureUseD setting or did you change it? The way things are worded in the ISO update is confusing for a few people I know including myself.

Ok got it, I only read what the update was on page one and that confused me but after reading 76-78 it makes more sense. I'm still not sure if I need to make any changes to menus 10,12 though.

If your not experiencing WG rattle and you are happy with your pedal response.... no need to make changes.

Does menu 12 have anything to do with the car oscillating back and forth or kinda surging at low speeds (20 or 30mph)? I was able to fix this in ISO25 by changing meun 10 to 70.
now its returned in 26.5

Just converted my G5 board to ISO, holy sweet Christ this thing is GOOD, no more low throttle jitter, very smooth, not peaky like before…

I’m going drag racing today and I have some questions.

I see the 18.5psi max on racing map 7. What is the max boost on Map3?
I see setting of boost additive 0-75, What is the 75 boost target? (if that is the correct question to ask)

Map 3 is still a variable target based on the additive, meth flow, and timing advance. The range is 0-80 where 0 is around 13psi and 80 is around 20psi peak. We suggest 40 for pump gas, 60 for E85/race gas, normally.

I accidentally changed Menu11, the default is still 80 correct?

Also, maybe someday we can get a FutureUse option to swap menus 10 and 12 to menu 1 or 2? When you are trying to dial it in its a lot of button presses to get up and down all those menus each time!

Menu 11 adjust itself but 40 in dash is the default.

No plans to reorg the menu as it would cause mass confusion. It's a lot of clicks but once dialed in should not need to be touched.

The 26.6 firmware is by far the best firmware I've seen with the G5 module, smooth with zero waste gate rattle on my car (FBO, MT and BMS flash). Those who had trouble with any of the previous '26' firmwares should definitely give this one a try as Terry did a great job combining the best of 25 and 26.

Meth will flow on map 3 and map 7 without adjusting any FU values.

Thanks,my meth was low. It's flowing fine now. Map 7 does kick ass better than 3 I noticed.

Default new user! - 09-22-2013, 02:20 AM

Hi guys

New user here, from Europe. BMW 335i ´07 E90. I have a few questions for you experts...

I have a JB G4 in my car now, and I am about to install JB4 G5 (bought it from a friend, orig. purchased from BMS in june 2013) with USB cable + DMS DCI.

I presume my G5 board is not loaded with ISO software yet.
It is correct that I need to snip the 2 diodes on my new piece of hardware? – just want to be very sure before doing this 

Software – which is “the best” version right now? I have no interest in beta testing, I just want the most stable version there is..

When I want to update the software in JB4 – can I do it with my laptop, in the comfort of my couch? Or does the JB4 need to be installed in the car?

Install – my previous JB4 G4 is from august 2012 – are there any changes to the wiring harness, or can I just hook the G5 up to my G4 harness?

Do I need to reset the JB4 in a anyway, as it used to work in my friends car? How?

I live in Denmark, and I will be running the JB4 G5 + DCI + octane 99 (shell Vpower) – all else stock. Which maps will you recommend for me? Map 1 and 5 should be ok, but what about map 2? Isn’t map 2 running lower boost than map 5?

I hope someone will take the time to sort me out – thx in advance!


regards René

1. You need to spend some time reading the N54 ISO section, it takes time to get used to it.
2. Yes, you need to cut the 2 diodes, because your G5 board is before 8/1/13.
3. The latest version is posted on the N54 ISO section at the bottom for download. only N55 is beta ISO.
4. JB4 needs to be installed in the car to update the to latest firmware.
5. Just install the new G5 board and forget about being creative with the harness
6. No resetting needed, just install the lastest iso firmware.
7. At 99 octane Map 5 will give you higher boost than map 2. Use map 5.

26.6 has got to be the nicest software version yet. Honestly don't know what more can be done. Buttery smooth acceleration, amazingly low end power even before warm up. I cannot hear an ounce of rattle at any RPM weather accel or decel. I have had two new sets of new turbos and since running ISO have always had rattle until now. Great Job Terry!

Agree 100% upgraded from 25 and I have to say WOW. Car runs the best yet. I did not even have to mess with settings 10 and 12 as the car feels just right at what I was running on 25 which was 80 and 28.
Great job.

For me, it's 26.5 FTW. Throttle feels better in smoothness and response.

Great job.
For those of you running 26.6, did you keep FutureUseD set to 20 (using ISO25 low throttle logic)? I'm still on 25 and love it, but I have settings 10/12 almost maxed out.
