seeing all these built motor threads made me want to go drive. i played with the ebc a little, and logged some runs. its 71 degrees outside, which might have something to do with it, my sbc-id ebc is set on auto, 9psi, gain 30. my forge actuator has the 9-15psi spring and its set to around 13psi, i guess. here are a few logs, the boost is holding MUCH better. peaking out around 10 and dropping to low to mid 8s on some runs. others it peaks around 8.5 to 9 and holds steady to around 8.2-8.5. below are some datalogs, the one with the 3 blips is a 3rd gear pull from 3k rpms to redline. there are 2 pics to show peak and ending boost, the middle 2 are peak and ending boost on a 4th gear highway pull and the last is a pull from 3rd to 5th. dont know why RPM isnt logging, i gotta work on that. now im gonna turn it up and see if i can get it to hold 10psi.

 

Very nice-I love this BC and didnt know it could log-ha, thanks for posting.

 

Nice Tig! I can't believe it's that cool where you live. Here is Fla it's still hot as he!! at night. Good luck. You are the Davie Crocket of the APS world

 

Tig,

Great runs.. But seems like you might have the same problem I have.. I get only 8~9psi during the drag runs (1st, 2nd,3rd, 4th gear power shifting), but get like 11~12psi during the dyno style run (in 4th gear from 2000rpm to max rpm).

Your RPM might not be logging because you have to tell the zeitronix software to read the first cylinder's RPM. Try this.

 

ill try that leeboy, i recently downloaded the 2.06 version software from the zeitronix website and i probably didnt correct the settings. youre right about my boost, on runs from a dig, i can only build about 9psi, but on rolls i can build higher, i think thats pretty normal for these cars tho, higher gear starting from a low rpm builds higher boost, if im going 70 in say 5th and punch it, i get 12psi in about 2 secs.
