port polished l98 heads 2.02 1.60 valves with this cam from comp 08-305-8, HSR intake and fuel rails, stroked to 383, running 36lb injectors. I have a speed density car 1991. Anyone running a chip on a similar setup? cant afford the fast xfi or accel right now. Any input would be great. thanks

 

why couldn't it? granted, it's going to be a PITA to tune with that kind of duration, but the aftermarket ECUs aren't any more versatile than a well documented GM ECM, which you running $8D, you definitely have one of the more well understood masks.

 

not sure which one I am running. All I do know is that I have a LB9 in a 91 formula WS6.

 

if you've never changed it, then yes, it's $8D running on a 1227730 ECM.

 

ya its never been changed i bought the car from the original owner and he never did anything to the car. As far as ECM's go how good is this $8D

 

well it's been patched to allow for a lot of things the factory never intended... i believe there is a thread for it, something like S-AUJP or Super AUJP, something like that. there was also a boosted 8D mask that was at least being attempted at one time, i'm not sure of the results though.

 

well hopefully PCMforless can hook me up on a great tune

 

tip: buy from a knowledgable individual, not a company.

 

why u say that? I have seen more good then bad about PCM. I would rather dyno tune but I have yet to find someone that can actually do it here in town

 

more often that not, a company just does generic changes with no regard to how it actually performs(hypertech is horrible for this, actually had one of their chips from ~1988 in an 85 IROC).

with the kind of motor you have built, i wouldn't trust those kind of changes. and depending on what they're charging, you may be able to tune it yourself cheaper.

 

not sure what exactly is need to tune myself, guess Ill have to research it

 

assuming you have a laptop: an ALDL cable, a chip burner and a chip or two.

ALDL cable could be made yourself if you're good with stuff like that, or buying one isn't too expensive ~$60 at aldlcable.com

burner: a willems is super cheap, but requires a bit more conectration than a BURN2 from moates(~$85)

chip(s): $5 each at moates.net. and since they are EEPROM, they take all of 1/4 second to erase and maybe 3-4 seconds to program.

so for less than $150, you can ensure it's a perfect tune. i can hook you up with some autotuning stuff to get fuel corrected pretty quickly using tunerpro V5 and either excel or openoffice.

 

cool when I get the motor finished Ill have to hit you up for the programing thanks

 

i want to chip my 88 iroc 5.7 and wanted to know what chip would you guys prefere and does it reprogram the settings for the transmission too? thanks
