That actually sounds kind of fun. Sameday track sessions swapping out hardware and datalogging the whole thing and video.

If one is lazy to datalog, what setting would you run if you only had DCI, upgraded IC and extra OC. Stage 1 or 2?

Hi Adrian, The dyno seems like the best option. Neither a BT or V3 datalog is going to show us how much boost is being held through shifts, only whether or not the throttle blade is open, and what the boost level is in front of the throttle body. It's also not going to show how smoothly that boost is being applied. Doing full 1/4 mile passes on the dyno is very common and a great way to troubleshoot shifting related issues. This goes without saying but datalogs will also be captured to correlate to the runs. Is it possible to enable the V3 to log via the BT cable? This would greatly simplify things. Many relevant parameters are blocked out / not viewable in the V3, like target boost. Also since TPS is being sampled directly it won't have the same latency you would see picking that signal off the filtered CANbus. Mike |

If you need a car to perform the test on, I'll volunteer. I live in Portland, but could drive down to SF for the weekend.
My car is mostly stock, especially compared to many around here. Riss OCC and Rix boost gauge are the only things I have close to engine mods. Let me know if you need a test car! |

Although Boost will read differently on the manifold side of the throttle body to the FMIC side of the throttle body, it will be within 1-2psi once the throttle is above about 70%. So if were to log the DBW throttle position and the pre throttle boost, we would have a good idea of what the boost is downstream of the throttle. If the bogfix is working correctly on both tunes, the actual time the throttle is closed will be very short. I know this is the case with the Procede. There are inidcators that will tell how fast the turbo is spinnning during the change... the slower the turbo is going, the lower the boost will be immediately after the throttle opens when the engine starts consuming boost gain. With the CAN bus, some parameters are broadcast on the CAN bus and do not require the diagnostic system to access. This is generally data used by other modules like the display cluster etc. Other parameters can only be accessed via the diagnostic interface. Unfortunately only the BT or Procede can use this interface at once... not both. Some of the recent features are reliant on this data, so therefore we could not run these features if we allow the BT to take the diagnostic interface. At any rate, the Procede logs quicker and for most CAN parameters is recording exactly the same information (the only exception being one ignition parameter that records the actual ignition with Procede CAS effect), so I am confident that you could log JB with BT and Procede with its own logging and compare the results.

man if this NLS system works anywhere near as the WOT box my friend uses on his stage3 srt4 in HOM/METH then it will be awesome! i've been waiting for you to do something like this shiv! since my friend did it with his car not long ago...i would jump ahead, then hold, then get passed ~110mph...now..i shoot ahead in 2nd and before i reach 100mph he is passing me.
it will be interesting now because alot of his gain would be during that shift at ~100-105. he runs 12.1@116-119 shifting slow because his clutch would slip...now he has a sweet clutch and will break traction in 3rd at 40mph... so we'll see how it goes! this is looking up shiv!

I'd love to see a neutral third-party head-to-head comparison! This is the best way to get a true fair comparison without the theoretical back-and-forth that can go on forever.

Attached is a datalog from a little testing tonight. This shows how quickly the throttle blade (blue line) is following the pedal input (purple line). What you can't see on this log, or any log unfortunately, is how much boost is being held through the shifts. But trust me its plenty, I was getting very sideways during shifts. Will need to rig up a camera and videotape the boost gauge for that one. . |
