R32 Gtst Rb20det Boost Cut?

[Stunn-R]

hey guys also wondering what the boost cut is on a 32?

ive run 14 psi and its fine , will 1.15 bar be ok?

[TTT]

there is no boost cut.

[Stunn-R]

yay thats what i thoughT! thanks heaps man!

[TTT]

there is an airflow cut so to speak though..

i had heard somewhere that rb20's didn't have paris hilton (aka rich and retard), LOL. but since it has to do with the rb20 i never bothered finding out for sure

[Stunn-R]

please explain! i thought there might be one, my avcr went to 1.3bar and it was poppig, i assumed it was a cut of some sort or it was just missing.. one of the 2 ..

*patiently awaits your post hahahaHahaa

They do have R&R, there's just a lot more tolerance than a 33 ecu.

[mad082]

well the ecu cut in my 33 was savage. like someone had jammed their foot on the brake for a second and then it kicked back in. that was at 15psi (about 1 bar). if you got to 1.3 bar then it's pretty safe to say that you don't have it

[Stunn-R]

ahh! very interesting stuff bubbA!

i miss my rb30s, vl turbos ftW! hahaha

[bubba]

Sorry, removed it coz it was a bit off topic

P.S. my 30 is twincam

[Stunn-R]

25 head? niiiiiiceeee

would love a setup like that ! one day... one day lol

[bubba]

sooooooooo much better than ye olde rb20

She was a daily driven 30 for nearly 2 years! Soon enough though mate, pulling the engine out tonight and putting it on the stand to strip it down and send to the machinist next week

Definitely miss her though, the laggy stag just doesn't quite cut the mustard

your AFM has a frequency range that it can measure.

it measures air flow.

14 psi = x amount of air flow.

17psi = y amount of air flow etc etc

once the amount of air going through is higher than the afm's limit, the ecu gets the message that it is getting too much air and the ecu adds more fuel..

so you get that misfire as it runs rich.

solution?

re-map of your ECU and an Z32 AFM.
