So the other day I was driving in 6th, dropped to 5th and went about 80% throttle and the car just cut boost and jerked. This has happened once since then, both times in 5th gear. Ive been running the gst base map for about a year and have had no issues until now. I also did a pull in 1st 2nd and 3rd and all pulled just a hard with no issues. Also I was in sport mode manual today and the car was shifting very slow. Any ideas? Thanks

 

post some logs

 

Which version Base Maps? The V30 and V31 Base Maps all have pretty safe boost control in high-gear, low-rpm situations.

At 2000rpm, 5th gear, the boost wastegate solenoid duty cycle (BWGDC) is less than 25%. Boost target is also low at that RPM point in that gear... like, under 13psi.


If you're running V30/V31, I can't see that "boost cut and jerk" being as a result of actual Boost Limit cut. Older V27 Base Maps, sure.

As above, post logs. If you can get 24/7 Standalone Logging working on Tactrix, it's pretty useful as a diagnostic tool. My vehicle logs itself on every trip. Haven't needed to plug in and check those mini-SD log files for over a year, but it's great to know they are there!

Im running v3, I don't have my tactrix right now as my friend has it. Im not very computer savvy as it took me days to flash it, so posting logs would be a challenge for me. But the funny thing is, it only happens sometimes, I guarantee If i go outside right now and did a fifth gear pull it wouldnt do it, but tomorrow it would. Both times this has happened it was in the higher rpm ranges, I would say 3500-5000The car just suddenly stops pulling, it almost feels like fuel cut as ive had that happen before(ran stock map with pill ) I live in NY so its very cold right now, would that have any effect?

 

where in ny are you? if you're close enough I can take a look at it for you.

 

Get the latest version of the GST basemap on there my friend! Betcha it solves your problem.

 

I just upgrade to the latest map, went on the freeway, and it did the same exact thing.

 

Just to clarify with this did the gear drop(go numb/neturalise) on you and it revved out.

I had it happend from 5th to 4th lucky i wasnt 100% punching it but it scared the s*** out of me and I've had it only ever happen once before into 4th not sure though it its a supersports flash related thing.
