Verywell - PROCede

Well considering the JB3/135 still used off the self parts for the exhaust, it sounds like some compromise is still being experienced. Maybe in AU they have other exhaust options...

The extra touque is removed from the PROcede map on purpose, to keep it "compliant" with the latest ECU. They could easily bump that up to close to 450wtq as we have seen in the past.

It would be nice to get a non-doomsday (a pre-29.2) map dyno from vishnu to see their touque potential....

Any facts behind this?? I noticed you said it will "most likely" trip the warranty code....

From speaking with Terry the map/run did not trigger any detection codes....

I thought Terry's 135i was v81?

The conversion is about 1.15 or so. So 400 at the wheels, means 460ish at the crank. I could be off a few points on the conversion

totally false.

i just got a bmw ecu upgrade and i still had my JB3 in the car with it defaulted to the high boost map.

rixster, kindly get up to speed on your facts.

Your "high boost map" doesn't make 420whp and 430lbft of torque. By Terry's own admission, that 422whp tune wasn't intended to be 29.2/MSD81 compliant. IIRC, his official answer was to get a GT1 to clear the manipulation code if you want that kind of output. So you might want to get up to speed on your facts.

Didn't we already establish that Terry's run didn't trip the warranty code? That's what is being disputed above, not whether or not he intended compliance.

LOL... I am trying to figure out if you are serious (and mistaken), or joking... Your "high boost map" is not the race gas "turbo melter"(as terry calls it) map that dyno was from.

He didn't make that map for v81 compliance... it will trip the code eventually, and it probably already did.

Terry seems to think that the warranty code only shows up along with a limp... but it doesn't... it shows up without any feedback to the driver whatsoever, and then is ready to be seen by the dealer.

The solution? run a map that is stated to be v81/29.2 compliant. Both jb3 and v3 offer such maps...

How much hp do you all think can be achieved from our stock turbo's (safely) before we need to think bigger turbo swap and/or engine rebuild? ... is 500+hp at the wheels possible? Experts, please comment.. thanks!

Here is the BMS JB3 Dyno to compare with the one Rick posted of Shiv's car.

Race gas map
Riss Racing downpipes
Riss Racing catback
Code3 intercooler
BMS dual cone intake

Basically same mods except for the forged diverter valaves.

Wow.. JB3 ftmfw..

Hmmmmmm...that's not what I experienced.

I got a limp mode/half filled engine light when my detection codes were triggered.

I cleared the limp by restarting the car, but the codes had to be cleared via scanner.

Are we talking about the same codes?

Implausible fuel/boost.

If its off by enough, it will be triggered with a limp, but if it "rides the edge" for long enough, a soft code that you never see will be stored. "Mass Airflow Exceeded" or something like that.

v3 users can choose to run the non-doomsday pre-29.2 maps if they wish, and there will be no limps, but the code may be tripped... which is why we suggest that people use the v81/29.2 maps to play it safe if they care about that... is it "too" safe? maybe... but better safe than sorry.
