I have a couple of pics that fit your criteria that may be useful to you. How can I send them to you?

@Terry, somewhat off topic but is there a size difference between the Regular heat exchanger you sell vs the Elite?

[Terry @ BMS]

No they are equivalent. The Elite is a little nicer, and weighs less. I think it's worth the extra $100. But we also realize this is a price driven market so have to offer the cheaper option also.

Terry is there some place we can email our logs to you? I keep posting on here but it always gets missed.

Hello @terry I was wondering if we can do a FF duty bias tune on our platforms yet? What does PID stand for and what does it do? I tried to look at my FF and WGDC they both 0'd out and my duty bias sometimes goes up. Thanks

[40Rolls]

Before I get some data logs this weekend after making an E30 blend, is there any settings I need to adjust on the JB4 for running E30? Would you recommend grabbing a few logs using map 7 before moving on to map 6 adjustments or is there a better map for e30 logs?

[Terry @ BMS]

Map7 is the most aggressive map. I'd start lower probably map5.

Just quote the thread or bump it if I miss it. Generally speaking I only need to see logs if there is some specific issue with the car we're looking for though.

Bump


Also any way i can make my stock ecu request more boost?

We don't have EWG control active yet so PID/FF won't do anything.

Not sure what the second question is.

[maxlegends]

I have a luxe and my stock ecu is asking for 8psi of boost and i want it to request say 14, and then add jb4 boost on top is it possible?

[EvolvingApe]

Hi Everyone.

Mr. Terry,

Would you mind checking out my logs? Both runs felt smooth for the most part. I might've felt some hesitation down low but it could've just been in my head too, not sure. Thanks in advance!

Do you understand how the JB4 works vs a full tune with ECUTEK?

[maxlegends]

Yes the jb4 is a boost controller which tricks and overrides signals that get sent to ecu and it can also adjust afrs and help trick the fuel pump. Whereas a ecutek is a direct change to ecu allowing u to play with more variables such as timing and ignition

[maxlegends]

And my question has nothing to do with the jb4, im curious what makes the q50 sometimes request 8psi vs 12 on the same exact car in different conditions. What makes those conditions?

Reread what I quoted in that post. That is not what you asked. But to answer what's quoted here, the ecu takes into account things like coolant temp and iats and adjusts the requested boost level. An example of this is if the engine is not warm enough it will reduce the commanded boost level.

oh max is here? let me get situated..

Looks good to me! How's the 1/4 mile times?

The factory ECU is LOAD based not boost based. It attempts to keep power equal under all driving conditions and climates, regardless of altitude, intake temps, humidity, and the sort. Boost is the variable that it's changing.

Hello everyone. I ahve a 2016 Inifiniti Q50 Silver sport running 93 octane with 4 gallons of E85 on map 7. Im just curious if you guys could take a look at these datalogs and see if all is well. Thanks

Seems OK but update the firmware so we can see fuel pressure!

@Terry can you please take a look at these logs. Both are 3rd gear pulls starting at about 2k rpm. It looks a bit strange to me in the middle of the run.

Mods: jb4 with fuel wires, stillen intakes, megan ldp
Map: 6

[jcoffeyy]

Sorry if this is a dumb post, but this is where I'm supposed to come to learn about this stuff right?

I just started diving into map 6 but I'm not sure what I'm supposed to be looking for in the logs to make sure everything is running right before bumping it up.

I havent installed my fuel wires yet. Should I wait until they're installed to mess with map 6?

Also, this is on 93 pump gas, AMS instake, BMS HX, Megan *********

Low cost LSD upgrade thread is finally up in this section. Pics wont upload so I linked to Q50.org thread.

I didn't get to check my 1/4 tbh but boy was the car hauling. I'm running 91 octane here in SoCal so I've actually gone down to Map 1 since then for fear of cooking the engine. With your input though maybe I'll go back up to Map 2!

That's awesome! I'd been looking for an LSD upgrade for some time now but was put off by the price. Now that you've provided an alternative though maybe I can finally give it a go. Keep us updated.
