Leave the settings at zero. As long as your still on stock inj.'s nothing needs adjusting.
Log again; RPM'S, TPS, timing, and knock.
Find an open road, third gear, from 2500 RPM floor it. WOT to redline. See what you get.
Your fuel pressure is set correctly, right?

 

[mhockeyjock]

Fuel pressure is set at 45, is this correct..

I don't know about 1g logs, but timing looks a little low around 3300 rpms. You might want to richen it up there, and a little more top end. I tuned my 2g so timing starts from 8 and curves upwards.

As far as needing an AFC with stock injectors, all DSMs run rich from the factory, particularly 1gs. If you know how to tune and keep your eyes glued to timing and knock, you can squeak more performance out of your car by tweaking the fuel curve a bit. Just be careful not to go too lean.

Should be at 43psi with the vacum hose off.

38psi on 1g. 43psi on 2g.

Thanx everyone for your help....

38psi on 1g. 43psi on 2g.

I was just gonna say that. It's 38psi on 1g with line off.

Check your timing, that's a lot of knock and your TPS is not even opened up all the way during any of the pull.....don't be scared of it, put it to the floor.

When you have raised fuel pressure like you did at 43, it lowers your pump flow.

Lower the fuel pressure, re-shoot the base timing to 5* BTDC and then go try again, this time make sure you are pushing the pedal all the way to the floor.

You might want to go a little richer across the board just to be on the safe side.

Post the new log on here.
