Need a chip burned 1992 B4C camaro

[kacy]

OK Ive been getting some work done to her, Shes running and driving and I finally got off my ass and welded up the exhaust , and welded in a extra O2 bung right at the y pipe merge, and picked up a used LC-2 wideband and Im gonna get it installed thenext warm day, but Im having fits with My rockers and valve covers, bought some tall aftermarket covers because my vette valve covers where hitting the top of the polylocs and not letting the gasket seal so I had oil leaks that scared me for a min. My plug wires where shit, kinda knew that so I got off my wallet and bought a new set of under header taylors, and figured out the remote coil really needed to be grounded to the engine not laying around loose. . So now its running alot better, found a tune for a 92 5.7 auto camaro and loaded it into the ostrich and played with a few settings , and i forgot the cam has alot more over lap. so That explains the ecessive richness at idle. I,m gonna try and tune it in open loop , but at least now I can drive it and it sounds bad ass, but its breaking up in the higher RPMS , I gotta go get a new timing light and reset the timing. Also installed a nice gear reduction starter I got off a 96 camaro LT1 , so that solved the not starting when hot issue. Its getting there and I couldnt figure out why I couldnt datalog with TPRT and tonight while messing around I figured out it needed a ADX file..lol Im an idiot.

it happens as everyone learns... where did you move to in FL?

I moved to FLA in may I think and stayed till august, I liked it, just wasnt finding the kinda work I needed. came to N.C. in august and finally had the time and money and urge to work on her. not working out though, it got greedy and drove it since it seemed to be running fair, I was loving the way it sounded with the exhaust hooked up and running on all 8 tanks to some new plug wires and timing set to a known value. burned the coating on my new headers . sad thing is it runs worse with the 350 tune and the 305 tunes seems alot better I drove it tonight with the 305 chip plugged back in. ran like a stripped ass ape, think it needs more fuel pressure tough, still had a slight stumble at the upper end of the RPM pull .

Holy shit I just figured out how to use the compare tool on turner pro. holy shit its like I know halfway whats going on how, I can see the differances in tunes between 2 or more.bins on any table...I can see it so much more clearly now, I was honestly about to give up. and go carb.

Going carb would be a waste and a step backwards. If you can tune a carb, you can tune with EFI.

The breaking up at high speed/RPM you speak of is because WOT is open loop, and I would guess your running lean. Alter your VE tables, and watch your wide band in these ranges. No factory chip (305/350/whatever) is going to *work* for you, some might have a few attributes to fit a certain situation better at times than others. I wouldnt look for pointers by reading other chips. If your engine isnt knocking or pinging (read knock counts too) then you dont have too much timing. A lot of timing is not neccessarily good, but most often extra timing will run better than too little.

Get a timing curve that doesnt knock or ping, and correct your fueling from there. Then you can fine tune the timing and fueling until you get something you really like.
