my guess based on 4.3 and 5.7 similarities, i would say the same as a 5.7 350.
not sure what those are but for the points i would guess and try .013 or so not going over .020 play around in those...
i put pre assembled heads on my first build that i tuned, i will never trust something i did not do again. bent and snapped off a valve that powdered a piston, busted cam into 6 pieces, powdered a...
what octane fuel do you run? i run 93 on the stock cam and 195* thermostat and all the engine mods(headers, afpr and whatnot) with top rpm/map spark at 29 and no knock. is something rattling around...
do you have catatlytic converters?
so no chip mods on ECM? the spark advance in datalog would only show your actual spark advance if the hack was burned into the eprom or "chip"
my intermittent code 33 ended up being a bad map connector. couple dollar ebay fix. might not be your problem. check connectors, maybe a short(which is hard to trace til it fails compldetely) make...
what is this table why does it look so rich?
I heard that. my old dual plane high rise intake wasnt fun in the winter due to icing. Paired with the vortec heads and being my first tune(4 yrs ago) it was a PITA
I have considered a new comp pin...
how about a pic of the underside of the holley where the fuel hose fittings on the gm pods come thru the holley?
Thanks for that fantastic answer. its difficult to search thru all the threads for answers. I've just been wondering about weather effects for a while. AE seems like something that should be good all...
yes i have an WB afr guage hooked up. no changes were made besides changing to a new icm when hesitation began. could the icm fail in a way where it works most of the time but sometimes changes my...
I was wondering about if AE should be adjusted for cold weather and then raised up for when summer rolls around?
I'll start here. c1500 Silverado 5.7 very light short cab step side. with two...
i had two icms go out in 3 weeks now. but my connectors where a little loose.(maybe they loose connection enough with engine vibrations to shorten the icm life?) maybe check your pigtails? also my GM...
it seems most don't last long but every once in a while, one finds a good ICM that lasts a lifetime. dang even the acdelco ICM failed?
are you running a modded computer?
i just had one fail a few...
my plan is to get this one to last twenty or so more years at least. ill throw up a project thread on here when i finish transitioning between laptops
I'm interested in a small quality vid that i can play over my speakers while i watch. totally awesome that that is working out. i like. and im still not sure what happened to that engine. cam or...
Been away for 3 or so years and figured I would post here again since I had to reactivate my account. It's also a good place to record what I'm about to post.
So hello again everybody, new and...
i blew that engine up, and now have a slightly modified stocker with my own chip burn. building a new powerhouse for it soon with new tranny.
and that supercharger woulda been sweet :cool:
very nice, I have an extreme EFI throttle body bore on my 5.7 throttle body and it measures 1-31/32 of an inch. they say it flows 720cfm.
*pretty sure I got it from extreme EFI.
and lionel.....what the hell are you doin? seriously?(both questions are rhetorical) 4yrs later? someone just wanted to talk about a transmission. stop..just stop.
cdeez, you need to just ignore this lionel thing.
you could boost your bpw up and make sure your highest numbers on your VE tables don't add up to over 85
correct me if I'm wrong. but I was thinking cold warm up afr should run a touch lean to help it warm up faster?
can someone point me towards a good wideband tuning AE post or thread?
i got my bungs in now for both narrow and wideband, tuned to the wideband and the thing rips tires, but then a few minutes...
