Terry already confirmed that RS's can handle +5psi on race gas. Also my boost logs haven't had anything on them so far to be concerned.

Met a q60 red sport guy today have been runnning +7 on jb1. He said no issues, he is on e85 mix. I have ran +4 on jb4 on 91. Car pulled really strong, but I toned it down to +3 max tapered.

Wife out for a test drive now. She loved the JB1 but felt it was a little harsh.

Curious to see if she finds the JB4 more civil. I'll post a firmware update tomorrow that enables code read/delete and refines boost by road speed user adjustables.

hey terry, i dynoed my 2017 3.0t thats currently on map 6 of jb4 with a peak boost of +8 from 4k-6k rpms. just went and got the car dynoed and this is what i got.

https://imgur.com/a/i4X3o


pretty sure it was low due to the heatsoak. all i have is a catback exhaust. the air/fuel at the bottom drops significantly after 4krpm. can someone explain to me why i got so low?

Have the JB4 log to match so we can see the tuning details? If timing is going too rich it might be the DME enriching the air/fuel due to higher calculated EGT readings or could be an indication you have boost turned too high for the octane level.

She likes it a lot more - says it is nice and smooth all the way through 6k rpm unlike the JB1 which she felt was a more abrupt hit. She feels more confident getting on it now.

I haven't driven it yet - been too busy waxing my new F150. Also a twin turbo that will eventually get a tune.

Hey All,

Just ordered the Infiniti Sport Exhaust w/o mufflers and the full. Z1 race p1pes. About to order an intake. For those of you who have the AEM, Stillen, or Powerpro intakes installed, are you able to push all the way to +7psi on the JB1/JB4 and have you had any issues with the intakes?

Thanks

I had the AEM intakes and while there were no drivability issues, I was getting constant MAF malfunction CELs with them even after the software update. I did get the same CEL code on stock intakes the other day which made me chuckle a bit. My car is super sensitive it seems. My brother had the Stillen intakes on his RS. No CELs but constant drivability problems so he went back to OEM as well.

Pretty good numbers, but like Terry said sometimes less is actually more. What fuel were you running? What were the AF ratios and timing? Remember, these turbos are tiny and inefficient at higher boost, overwhelming the cooling system and ultimately producing less power.

What do you think, rs awd on 94
psi_curve[0] = 30 '1500
psi_curve[1] = 30 '2000
psi_curve[2] = 40 '2500
psi_curve[3] = 40 '3000
psi_curve[4] = 40 '3500
psi_curve[5] = 40 '4000
psi_curve[6] = 40 '4500
psi_curve[7] = 40 '5000

You're probably reading boost wrong, then. I dyno tested all the options and all made the same boost/power output.

Added new JB4 firmware to the 2nd post.

Enabled boost by speed. Values of 0 disables. Otherwise "1st gear" sets maximum boost added below 31mph, "2nd gear" sets maximum boost added below 55mph, and "3rd gear" sets maximum boost added below 84mph. Generally speaking this feature will be used by RWD vehicles and in most cases only in 1st gear, with a setting of say 2psi in 2nd gear to assist with traction as needed during launches.

And here is a log of that function in action. I've set 1st gear to 1psi, 2nd gear to 2psi, and 3rd gear to 3psi, so you can see in the log how the feature works.

The first production units are still not on my desk. When I have them expect to see a post in this thread about it.

So, installed the jb4 firmware, limited 1st gear to 1 psi. Definitely gave the car some traction. When I come out from a turn on a stop, I usually hear the tires burn at half throttle. Now it takes a little more to burn tires from a stop, but it just goes, no wasted power from spinning. Again, thank you Terry.

any benefit to AWD vehicles? ill stilll update as there is other functionality enabled with this update, just wondering. Btw you were right about before the Sport mode just draws out the gears longer, i just feel the difference in standard mode more than in sport mode.

No need to limit boost on AWD cars, from what I've seen so far.
