Dyno last night

Re:Dyno last night
Ya nice torque numbers.. Your graph is very flat which is really nice..
But i would add some more fuel right where your peak hp and tq is.. I usually aim at 11:5.1 all the way across..
But i like my cars very safe.. Incase something goes wrong.

Re:Dyno last night
i was running that original bin that you got at .5*/lb and it seemed ok, but i never dyno'd on that bin. however, i looked at the duty cycle and they were almost maxed. as you add timing it'll get leaner and you'll need to retune the afr. when i altered that bin and went to .75/lb it was much richer and i had to lean it out, which is what i wanted to do to lessen the duty cycle of the injectors. i've been too lazy to install my walbro, so i am still running a stock fp.
i ran as much as 27.75* at 11psi on that one map and it seemed fine...next time i hit the dyno i'll have both chips handy to see if there is any bump in hp and if i can hear any detonation. i never heard any before i was running it.
biggest thing is you want to tune afr at a conservative amount of retard then bump up the timing and retune afr each time and see where the hp is. once you stop making more power, if you don't have detonation, egt ok, and duty cycle is ok...then you should be ok.
