Datamaster showing "blips" of ~46ms inj dc @idle

Yep, just what the title says. DM is showing "blips of 20 and sometimes 46 ms duty cycle, yes 46 not 4.6. Is this just junk in the data stream or is this possible? I'm trying & miserably failing at tuning this POS $58 749. I haven't left the idle params.

I have my own little hole in the ozone over my house with all the HC's I'm producing. Should be good for tanning this summer.

hey i'm in CT also, i just started working on the $58 code from $8D and it seems a lot more involved, granted i only have a 305 but it's super rich compared to the 8D i started with, but i just got my procharger and need to get it to work, if not it's $8D and the FMU

i think something is wrong with the $58 ADS file, i'm showing 6ms at idle compared to the 1.x with 8D

The blips are normal. It is caused by the PW RAM location being 'worked on' as the code is executed. All depends upon when the ALDL stream acesses the data.
