BlazeRex Posted June 4, 2013 Share Posted June 4, 2013 Are you 'pro-tuned'? or is this some OTS basemap? Link to comment Share on other sites More sharing options...

CapnJack Posted June 6, 2013 Share Posted June 6, 2013 Do a 3rd gear pull starting a little earlier in the RPM range (2200 RPM) and repost your results. Link to comment Share on other sites More sharing options...
iNVAR Posted June 6, 2013 Share Posted June 6, 2013 1) List mods 2) Your WGDC never seems to change except from 0 to 67.06. That is... peculiar to say the least. 3) 5MT or 5EAT? Link to comment Share on other sites More sharing options...
ctlex Posted June 6, 2013 Author Share Posted June 6, 2013 Ill see if I can do a 3rd gear pull tomorrow and then report back. My mods are: Perrin top mount Cobb catted down pipe Perrin catback Agency power equal length header Invida up pipe Vf52* Deatsworks 740cc injectors Deatsworks dw65 fuel pump* gfb diverter valve/bov underdrive crank pulley k and n intake perrin catch can halman mbc and yes its a 5mt.

BlazeRex Posted June 6, 2013 Share Posted June 6, 2013 Yay! MBC! Probably normal temperature swings. Link to comment Share on other sites More sharing options...
BlazeRex Posted June 6, 2013 Share Posted June 6, 2013 That and you need to start at a lower RPM Link to comment Share on other sites More sharing options...
iNVAR Posted June 6, 2013 Share Posted June 6, 2013 This is a good example of why I think an MBC shouldn't be used on a street driven car and if it is, it should be made VERY clear to the owner what the pros/cons are. The OP obviously wasn't informed of potential shortcomings, such as having to adjust by hand for temperature fluctuations. Furthermore, we can't even diagnose anything from the logs because the PWGDC values are completely meaningless. Is his MBC broken? Is his actuator weak? Is it simply a temperature problem? We really can't tell.... Link to comment Share on other sites More sharing options...
ctlex Posted June 6, 2013 Author Share Posted June 6, 2013 Hmm I cant beleive I didnt think of that since its warmer out the air is less dense meaning less boost. The mbc came on the car so I just stuck with it. I doubt there are any wastegate problems since I just put the vf52 on 5k miles ago. Ill try adjusting the mbc and logging from a lower rpm.
