AFR bias is not active, unless equipped with port injection.

Good morning Terry!

Yes, my car is equipped with Fuel it PI and BMS PI controller. The fuel was E45 + dual cm5 meth (75:25)

That's why I am confused higher AFR bias actually worse the FP_H dip after gear shift. Could you share any possible causes and solutions?

Thank you very much for your help and time!

Cheers,

Li Wang

So you're running both PI and WMI? That's pretty unusual. Why?

Are there any wiring differences for the FSBv2 on this firmware? I tried to hook my meth back up last night, and I'm just getting nothing from the pump. I checked some things with my multimeter, but I don't know what specifically to look for where.

Other than that, this firmware is awesome. I'm on my stock tune at the moment, but with map 5 and 93 octane, I'm hitting 17+ psi on the regular.

Should work the same way. Select map3, press purge button.

The V1 and V2 FSB have a wiring difference with the solenoid though.

Yeah, I missed that at first but then corrected the issue based on the install diagram (as I had the V1 before, and the V2 now). Would that fry anything if wired incorrectly?

Finally had some time to play around with "Ver7.3" and it is really great! Boost surge at 3000rpm is almost completely gone and part throttle driving is really smooth

However..
#1 As soon as I disconnect the interface (PC or Mobile) boost doesn't come on until 3800-4000rpm; so I still need full time CANbus. Obviously I cannot log this so not sure what to do from here - maybe just accept it
#2 That Map3 Target drop persist. Only happens on Map3 and around 4800rpm. I'll check later if full time CANbus solves it.

Hi Terry,

My daily fuel is E35-E45, and daily 22psi flat boost target.

I use PI to help the weak f30 n55 hpfp, and I use dual cm5 70:30 to cool the IAT. I found with higher IAT the timings were very low, although octane maybe is sufficient for this boost level.

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

Cheers

Li Wang

Is it a BMS PI controller running that end?

Yes, Terry.

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

#1 Hazard flashing if meth flow below e.g. 80 in map3
#2 Gauge sweep to active map on start-up
#3 Hazard on full time if safety is triggered

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!

Meth Flow Scaling is 60 by default. If you set it at 40 a lower flow/volumen will be interpreted as full flow - less safe.

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.

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.

Very sure you dont need to do anything, just wait for the BEF

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
