Hello, I'm trying to do a little research and I would like a few more people's logs to look at. What I need is really easy.

I need a short log file showing your injector transition area. This could be wide open throttle, or a roll-on... doesn't matter. I just need to see one run where your secondaries kick in. The only columns I need are Time, InjFP ms, and InjFS (mS)


I would like some examples with stock 550/850, 850/850, 550/1600, 550/1300... etc.

All I need to know is your fuel injector sizes and the short log file that shows you on the primaries only, then activating the secondaries.

Thanks,
Brian

Here's a couple for you. One is cruising at 60mph, and the other is a WOT run in 3rd gear. My maps aren't all that well tuned yet, but I'm running 4 850's. Honestly, the logs are a little old, so I can't remember if these are using the old transition settings or some tweaked ones.

Here's the other...

Thanks for the logs. I am trying to figure out exactly how the PFC handles transition and I still don't have enough info..

I gave it more thought last night, and that should be the stock transition numbers. I had changed them a while back, but for the WOT run, I think I had put them back to stock...

Well please share if you find anything. I don't understand it either. I had read about the "staging points" but I still don't really fully understand why it does what it does. I know I have a lean spot at 3500, which doesn't make sense to me, since when I was changing my transition settings a while back, it looked like it was changing roughly the 5000rpm area...

I really hate my 850 primaries. I was going to try to tune them out, but I think I'm gonna just live with them for now and switch back to 550's first chance I get...

Good luck!

Attached is a truncated log for your analysis. I am running 1300s with a lag of .2 and a transition at 40%, stock primaries.

Books and Brian, do these knock levels seem to high? When do you start getting concerned?

My knock levels are considered high. Although not recorded in that file, my knock readings are in the 80s while under vacuum in the 2,xxx rpms range. I have tried but failed in my attempts to isolate the cause of my high knock values. There is a thread (in this section) discussing what I had performed to resolve this issue. Eventually I replaced the knock sensor without successfully reducing knock. I have reduced timing and increased split and I believe my AFRs are relatively safe. You'll notice this as you examine my file for those data points.

On a side note, if you open the file using Excel the columns tend to align better.

books, are you using a torque brace that the knock sensor might be hearing?

I am not using a torque brace. The knock levels will exceed 80 around the 2,000-3,000 rpm range while the car is in neutral.
