Disclaimer:

I forgot to log knock correction, so these logs aren't as useful as they could be. Still, some people might like to see this stuff.

The conditions:

12C, light rain, 94% humidity, winds W 19km/h, pressure 100.71kPa, 94 octane, sea level, VDC ON, S#, AUTO-.

Notes:

The first and third logs were taken in 3rd gear while the the second log was taken in 4th.

Looking at the logs it looks like I'm hitting a maximum of 19psi in 4th and tapering off to 14psi by redline. Another thing I've noticed is that the '08 speedo seems to be much more accurate than my '05's. At 80km/h, my '05 would show a vehicle speed of 76km/h where as my '08 shows 81km/h.

I'll post up some new logs later that have KC field.

Hey, While your at it can you log injector times? BTW, This turbo seems very capable to get more out of it, however fueling looks like it might need to be upgraded. The duty cycle is almost maxed.

I need to get some logs done on my car. Did you use the cobb ODB dongle to log. Did you need a special driver?

I used my old Tactrix cable (OpenPort 1.3 iirc) + latest Enginuity definitions. Drivers are included with ECUFlash.

I agree about the fueling too. At the minimum I'm going to get some Deatschwerks 650cc injectors before I go stage 2.

data is hard to read. You should post excel spreadsheets

I had already done this for myself so I'll save you some work.

I guess i'm going to have to pick up the Tactrix cable because I've had no luck with the Cobb cable. Is this the correct one? tactrix

Thanks

yeah, this is why the injector on times is important to me. I'm wondering if bigger injectors can be avoided with increased fuel pressure with tuning alone.

Thats is of course if the OEM injectors are rated for higher pressure.

IMO, you are probably fine with Stage 2 and these injectors for peak torque since thats a bit lower in the RPM range, but if you want to run more boost at redline something will need to be done.

Thanks for posting those logs BTW. Once I get my logging connection figure out I'll try to post some too.

Has anyone here modded their injectors on an 08 yet? I can't imagine it has changed too much. On 05-07 I think doing this put the injectors around ~950cc.

07-08 injectors are topfeed where 04-06's are sidefeed. Topfeed's are alot more common so it will be cheaper and better selection for us.

Thanks for that and yes that is the right cable. You might want to wait a month or so because the maker of those cables (Colby) is working on a CAN version. With the 1.2/1.3 cable you can only datalog; you can't download the maps/ECU memory.

Last I checked the CAN version should be for sale on June 1st...

its been a while since ive been to a tuning session but from what i remember its not uncommon to get the sti's injectors to 110% duty cycle.
