Default How do my logs look?

I think the car is running strong, yet I keep fouling plugs. It looks as if I'm running a tad lean, so I increased fuel pressure just a tad.

What do you think?

Default Looks good to me.

.86-.87 is a good place for the o2 readings and 180 g/s seems good too.

What injector/fpr setup are you running?

Every thought of going to some 310's and lowering the fpr to 3.8 bar?

Default Please explain..getting ready to install the K04 and

have been trying to find an alternate solution to raising the fuel pressure to force more fuel through the stock injectors. Installing a 5 bar fuel pressure regulator seems like a band-aid solution. I would prefer leaving the pressure at a stock 4 bar and installing larger injectors. Any advice? Also have you seen any problems running at 5 bar...burned out fuel pumps, etc.

TIA

Default What year car?

Because there are some chips out there for the ndbw that run 310cc injectors at 3 bar and some people have even tried running the stock dbw injectors at 4 bar. Some of those that are running the J31 chip for the 2000 have found the bosch 310cc with a adjustable fpr at 3.6-3.8 bar to work very well.

Default well the new MAF definately helped things!

those 02 readings look good, doesn't seem to be leaning out up top. As I've said before I've heard some stuff indicating that 02 readings aren't the best tuning tool. Got to get it on a dyno w/wideband anyway and see what kind of power you're putting down!

thats awesome, with 4 runs you can tweak the FPR on the dyno

Default Using 02 readings are fine if you can keep the exhaust temps the same

during each test. Higher exhaust temps will cause the 02 readings to lean out.
