They are both roughly the same and positive. Wouldnt he want to drop the injector scaling just a touch and see what happens?

I had thought the fuel trims were getting better, since we've made a lot of changes to the latency. What's still wrong?


What injectors are you running?

Looks like you have knock between shifts...you need to address that since more than likely its throwing an octane flag thus richening the mixture for an instance.

IMHO if there is no knock at all through redline ie 1-2 counts then the car is no where near the limits of the tune or the fuel you are using.

You're right, it is not. we just started getting the DD tune right, and then I drove to sea level and hit the drag strip - not the best way to get a tune dialed in, hah. I don't knock on every shift - just the ones I botched. however, it seems I always get a quick lean spike after each shift.

Yeah keep playing with it, you'll get it in no time. Try to lower the ignition timing in from 0-100 load limits and from 6000rpm-8000rpm, to lower the knock tendancy through hard shifts.

Warr what are you doing in SD? You can try giving Reese Tuning a call. They are in San Diego. 619-749-0156. Hes got a DynoJet and might be able to help you out with the tune for sea level.

Oh, don't need any help from a shop or anything. I have tuning support and am doing well, but I was looking to get some thoughts from EvoM folks.

I'm in San Diego at the SCCA Solo II National Tour - today and tomorrow.

If your getting a lean spot between the shifts like i did with lean spool off then richen up the low load areas in the higher rpm range from 5000rpm and up between load areas 80 - 180. This flattened out the lean spike allowing boost to come on back quickly without knock and increased timing for me
