Hello! first post for me here... I have a '98 camaro with a forged 347- I am entirely new to EFI LIVE and am learning what I can. in the meantime, I just finished rebuilding the motor and tranny, and got the car fired up and recorded some logs of the car running. I saw a few things on the run that really worried me, so I'm not driving the car until I figure out what is going on. I'm tuner-stupid, and if someone can look at this i would be really grateful
power parts-
the car is a '98 z28 M6 transmission
forged rods and pistons
10.9:1 compression
trick flow 215 cnc heads
vengeance ported fast 90
nick williams 90mm TB
FAST 36 lb-hour injectors
stock z28 MAF
kooks headers + catted Y pipe
stock z28 exhaust catback
VRX5 camshaft, 236 238 duration, .601 .605 lift, 113 lsa
scorpion roller rockers
asp underdrive pulley
anyhow, the car is strong, but I think there is more to be had- and it has some serious issues if the log files are correct... I've attatched three log files and the base tune that vengeance set me up with.
I've got a few things in particular that I need to figure out:
the car starts very hard. I have to turn it over for 5-10 ten second bursts to get it to fire. the third log file shows the hard start, and once it starts, i have to feed it with the pedal for the first ten seconds or so until it calms down and idles at 1300
throws a cam position sensor code
* the lean fuel trim hovers around 8-14, shouldnt that be almost zero at full throttle?*
** EFI live is showing anything from -10 to 40 for the timing!**
the maf is showing a max of around 240 grams/second... I think this motor should be taking in a lot more air
very light surging around 1800 rpms
and lastly, the air bag light is on
anyone help me with where I can start with this? I've spent some time with the downloaded tune tool and it scares the crap out of me! I'd spend the rest of my summer trying to figure out how to tune a motor like this
