Hi,
So - I've read this thread and a bunch of other resources and am contemplating giving a go at cooking up a mild tune for my 2004 V70R MT sapphicama.
To get started, I predictably got some questions I'm hoping someone might be kind enough to help me clarify.
Current mods are as follows:
- B5234T3 block bored to 81,5mm with K1 rods and Wiseco 9:1 CR pistons (so slight deviation in displacement and CR from stock)
- Stock tune, stock injectors / maf / coils / fuel system / Pierburg TCV
- DO88 intercooler and intake piping
- Turbosmart shorty external CBV
- 3" Ferrita 200cell catted DP
- BSR catback
As it is, I'm running with the TCV unplugged (due to overboosting with it connected ever since the installation of the IC and DP which were the last mods). Even on WG pressure occasional aggressive pulls trigger a reduced engine performance message and the ecu intervenes with the power output. Now, before I even think of flashing anything, I want to figure out what exactly causes this. For that I would need to get some datalogs done and I think Vida isn't going to cut it in the long run...
So question one:
I have gathered a bunch of flashing / logging software recently made available but I can't figure out where to get the parameters list file (.exm) or if there's a way to generate it from my bin or what.. Or how exactly would one get to log with these tools?
In an effort to get an idea of what maps do what and which are going to need modification for a reliable tune, I've been comparing some QKHJ stock / Stage 1 / Stage 2 bins and am beginning to get a mild understanding of what it's all about.. However - I only have my current stock tune (which is QHHJ) in .veb format - I received this from Contrast and successfully flashed to replace the BSR Stage 1 tune that the car came with (and which ultimately lead to cracking the original engine :/) before any mods to the car and it's been fine. This veb file makes no sense to me when studied in TunerPro or WINOLS. I also have a 2003 stock QHHJ bin and I can easily locate the maps with their offsets when comparing this with the QKHJ bins. Which leads me to:
Question two and three:
Can a QHHJ .veb file be converted to .bin that would match a respective xdf?
Am I correct in understanding that a QKHJ bin could in theory be flashed to replace a QHHJ with no ill effects?
And finally, without trying to jump ahead of myself - I gather the increased CR of my engine would unavoidably call for changes in timing maps.. any pointers/experiences with this kind of setup?
I'm just getting started with this whole mapping idea and wouldn't be surprised if I'm actually in hopelessly above my head or id I can never actually summon the bollocks to flash anything but it would be an educating exercise never the less
Thanks!
