tuning my self ...
i have v 2.5 dsmlink and im wondering what lbs a min im getting at air flow 236gm ? im at 15 psi on a hx35 h1c
and what afr's are safe for e85? im getting under boost 11.8-12.1 regular aem wideband cruising afr's are still 14.1-15.6 and last timing tables under boost what is too much from what i have seen i shouldn't peak past 23 degrees ? or keep adding untill i see knock ? my global is at -34 with pte 880cc injectors and 480 dead time |
Re: tuning my self ...
You can right click on the "airflow" in your dsmlink and change the display preferences to lbs/min.
AFRS look good, however I wouldn't go beyond 17-19deg of timing. E85 doesn't knock normally, but when it does... Shit goes BOOM. |
Re: tuning my self ...
i just tweaked it some more i have the timing tables set to flat all the way across and moved boost afrs starting 11.5 and working its way to 12.0
i think i need to tweak dead time a bit im at 480 the 02 dosnt seem to cycle well |
Re: tuning my self ...
I like 12.5:1.
Careful with timing, as you can wreck stuff by running too much without ever seeing knock. Cylinder pressure skyrockets with too much timing. You need to tune for power not knock. My knock sensor became totally useless once I switched to E85 4-5 years ago; 1G's are a little different since the knock sensing system is over sensitive IMO. |
