Guys.
I have been running this gen7 for about 1 month now and have shared with norbs and some other the data I am seeing with my logs. The RPMs seem to be very jagged....is this what other logs from you guys look like too?
My car runs mid 10s nearly every pass 3000+ DA weather, N/A...doesn't miss a beat going down the strip and runs within a few .001 nearly every run, through the 1/4 mile intervals, when you break them down.
However these logs for RPMs SUCK. As you can see the output seems to be indicating that the RPMs are surging, but the car is smooth as silk going down the track.
If you look at the very end of the log, there are 3 peaks. If you scroll through that section - from peak to valley is a 600 RPM difference! In other words the RPMs while they should be climbing, are going up, then back down according to the logs.
I have a pretty loose converter on this car, its an 8" race converter 4800-5000 stall speed.
The sample rate for the log is set at 10 frames/sec....which shouldn't be too much I wouldn't think.
Can someone send me a log of their car through the 1/4 so I can compare.
If what is happening in these logs is truely happening, then I may have a problem somewhere.
I should also add that I have seen this same sorta RPM reporting when using my stock ECM, and logging runs on it last year. Do you think its in the distributer?
Any thoughts...I guess the main thing is do you guys seem similiar traces of your RPMs through the GEN7 as this?
