First Log using obd-II from Digital Tuning

[DSMvroom]

Both are 3rd gear pulls. How do they look? I had a P0120 Throttle Position Sensor and a P0201 Cylinder 1 Injector Circuit that i cleared and then did the pulls. Looks pretty good to me, but is that drop in timing when i mash on the gas normal?

Nice logs.
Maybe take teeny tiny bit out between 3700-4500 based on the second log.
It is normal for the ECU to pull timing when full boost hits.

 

[DSMvroom]

Based on the numbers I'm getting, do you think it would be safe to turn up the boost 1 or 2 lbs?

I'm currently running 15psi steady and the timing curve is consistently similar.

As I understand it, the computer will pull timing when it detects knock so using that sort of mentality, wouldn't it be safe to keep turning up the boost until i see the computer start to retard timing?

At any rate, a 190lph is on the way to help suplement.

 

[gsxtacy]

I would say your lean from 3500 to 4999. Your timing just lags at 10 degrees there for awhile. Like tooo long.

5000 rpm is the most important increment of our cars' power band, its the HP/TQ cross point. Might wanna richen it up just a bit.
