Well,
used this equation to correct my fuel constant for slightly larger injectors ( 336cc(32lbs) vs stock sc 310cc).
310cc constant 0.32359
New constant = Old Constant x (old injector size/new injector size)
nc = 0.32359 x (310cc/336cc)
nc = 0.32359 x (.922619)
nc = 0.2985502
Plugged that number into the hpt program and reflashed car.
Results.
It worked. I didn't have problems idling before, but now at WOT all my pulls thru the gears to 200km/hr (he he) didn't go past 101% of duty cycle. The other day i was logging 130% duty cycle of the injectors (yikes). Its not a pernament fix, but does show that it works. Only pulled on MISfire code when the injector cycle was 100% from 180ish-200ish km/h. They were probably close to clipping. not good.
But ya, just thought i'd share.

i read on a post somewhere that duty cycle should be under 80 percent at all times!!!!
tuning with your duty cycle? i hope you have a wideband!!!

yea improvement but your still way past the red line on those injectors

It's sad that I am pusing 370cc injectors to 93% heh...
good lukc bud!

Phil - not really. 370cc injectors aren't even really good for 300 whp reliably so I can see you maxing them out pretty quickly
When I sized 550cc injectors they were barely good for 400 horses. Really puts the stock 252cc injectors into perspective.
Time for new injectrors, I'd say!
