Still trying to get my car to cool properly. After several different attempts, I put a mechanical fan on and it immediately started to behave. Today, I finished up a shroud and ordered a fan, so I should be able to resume Sniper development soon. I'm already pretty close on my tune up.
I've been running the Sniper EFI system for a while and timing control and I also am barely getting into messing with the settings. I have it on my 430 with TA 284 Cam. Runs really well but I hear some pining at times when I got WOT. you are right, the WOT timing tip in is like an on switch, I need to figure out how to smooth that. I don't get the pinging if I ease into the throttle. Will most likely play with the settings as well but I also began running hotter after messing with the timing. I am running a Derale dual 12 inch fans with box shroud and a champion radiator controlled by the sniper Unit. Can't wait to see how your table ends up.
Either of you have any files you can share for base timing, AFR, and fuel map for a stock Buick 350? I have the Hyperspark dizzy and the Holley coil unit, and am running the progressive linkage and extended throttle arm, but I have offsets for those. Just wondering what AFR table you shot for, and your advance table.
Rockable, would you be willing to share the sniper AFR table and timing table? Or even the config file? I have a stock Buick 350 with stock exhaust manifolds.
This is what I used. Make an excel sheet by entering your timing values. Then copy and paste to the Sniper table. There’s a lot of good info on this forum. https://forums.holley.com/forum/holley-efi/sniper-efi/38339-revised-base-timing-table-generator-tool
