Do you have any suggestions for better applications? Thank you very much for your valuable comments!

Is it a BMS PI controller running that end?

Yes, Terry.

I use BMS PI controller, and I set my AFR bias around 60.

OK, finally got the methanol hooked back up and used the ISO 7 T3 firmware for some pulls. So far, I'm just using the default settings and no IAT resistor mod. I have my bm3 flash on, and I noticed map5 on the stock tune targeted (and hit) higher boost than with the bm3 BEF.


Here's the last log after several pulls, what are the current suggestions? I assume I can increase meth boost and flow scaling, but how much is recommended? When I had just the BEF, boost started at 21PSI around 3000RPM and faded to around 18.

Change your meth additive to 50 and relog!

Made both changes, and I got one run in before meth stopped flowing for some reason. Even prime doesn't work again. I'm thinking I have a loose connection to find somewhere... Anywho, here's the single log I got after making the changes.

Oh, and I also got a code 21A503 clutch: stuck closed but no warning lights at all. Very odd, haven't seen that one before.

Blown WMI fuse maybe?

Of course it was. Put a 15 in there, will get some logs in an hour or two.

So I got some runs with the meth actually working. What do you think the throttle cut/DME_BT drop around 2800RPM is about? Without the JB4/meth the BEF runs around 20-21psi, so I know it's capable. Also, any idea what the clutch: stuck closed message is about? It happened on the first run, but not thereafter. Think it's time to add the resistor mod back on?

Ok so, what you need is a backend flash as before you did not run our OTS in conjuction with JB4.
So I told them that sounds good to me and asked what I need to do to make it happen (at 6:23 PM) and so far (as of 10:11PM today) I have heard nothing additional.

Hi Terry, what would you think of this and can you implement it for us to achieve boost target in every gear in one setting.

We need less FF to achieve the same boost in every-higher gear.
so could we implement something like this:

currentFF = FF (jb4 input) +(8-#gear)*4


e.g.

constant int = 4; ? could we use FUA for it something else i don't know.
int FF = 95 [jb4 input].

in 1st FF = 95 + (8-1)*4 = 128
in 2nd FF = 95 + (8-2)*4 = 124
in 3rd FF = 120
in 4th FF = 116
in 5th FF = 112
in 6th FF = 108
in 7th FF = 104
in 8th FF = 100

Thanks for all the support you still offer to this minority

FUA is for diagnostic use only, not something an end user would use.

Last safety = 5 after update to 7_T3 firmware, review another 7_T3 log posted in this topic and find that most have the same behaviour, anyone know why? What's meaning of last safety = 5?
Thanks

Hi guys

I cut the diode, do the update ISO 7 T3, set PID 25 auto shift 60 defaut wastegate 80. I left FUA 0 and FUD 0. Since I have a low boost on all the maps with the Default "120308 Boost pressure lower than expected". I completely unplugged the jb4 to see if the problem came from the car. I have the boost without the jb4 so the problem comes from jb4. Someone can help me?

You can post a JB4 log or if you prefer try 1-800-psychic.

If fuel trims are stuck at 25, indicating open loop mode at full throttle, you'll trigger the fuel trim variance safety.

If fueling is sticking in open loop at WOT then you should address whatever is causing that. Normally an o2 sensor fault.

I was seeing a ton of safety 5. Which O2 sensor? I still have my ****** on the second O2 from before the BEF that's on there now. Should I leave it as is, or disconnect the whole sensor? I've got no codes, but who knows if we can really trust that...

Find that OBDII Dash '4 Delete Fault Codes can't enable after upgrade to T7.
the setting can't be saved to 1, it will auto back to 0 = disable
