Wastegate Duty Cycle
Hey all, I've just started to datalog my car and noticed that my Wastegate duty cycle was at 96% and would hit 99/100% with any throttle response. Is this normal for a Stage 2 OTS tune on BM3? I'm new to actually tuning and I'm just trying to understand what this means, if it's bad I would like to get it looked into, if it's normal for a stage 2 tune I'd like to know that. I'll post my parts list below. Thank you
List: Pure Turbo Stage 2 MST Turbo Inlet VRSF Chargepipe VRSF Intercooler VRSF Catless Downpipe Akrapovic Catback Exhaust BM3 OTS Stage 2 Tune - Boost is set at a max of 16.7 psi but I hit 18 sometimes at WOT. https://bootmod3.net/log?id=64be082cae729b0e48f0ab21 <- One log from the other day Last edited by Lyfe.In.A.M2; 07-27-2023 at 06:44 PM.. |

Hard to tell because you didn’t floor it at 2000 rpm.
Redo your log, full throttle 3rd gear 2-7k. Yes power will fall after 6500 due to the stock turbo but it’s standard practice.

yeah, its pretty normal looking at this particular log. Typically it hits high 90's until it reaches target then starts to open. Your's does this, watch it. When you first get on it, the wg closes until it reaches or gets close to target then opens.
but like others have said and my tuner instructs....Do a 3rd gear pull from like 2500-redline. |

I'm wanting to go with Jordan but I can only find custom tunes for 93oct instead of 91oct. I'm looking to go full e85 but not atm. Any recommendations? I live in California so 93 isn't available and I don't want to run an E mixture.

Custom tunes are just that, custom. It will be calibrated to whichever fuel you want to use. Until that can happen just take it easy.
