1994 Corvette EEHack Data-log Review
I was wondering if someone with more experience was able to review my data-log from earlier this afternoon regarding my recently rebuilt 355 LT1 with a LT4 Hot Cam kit and increased static compression (10.7:1). I have not had the PCM tuned yet but would like to possibly review before I do. I am unable to fully understand (at this point, currently learning) the data collected.
Besides the LT4 hot cam kit, everything is new (rotating assembly, heads machined, all new gaskets). The fuel injectors are stock (22lbs) and the throttle is stock, heads have been cleaned up and verified as 54.4cc.
I plan on tuning once I am able to pull the factory tune and save it on an external device.
Thanks in advance.

I would really like to hear about this also. It is a real shame the C4 section doesn't have a "Scan and Tune" subforum, because it probably needs one worse than any of the other era vettes due to it devolving into an arcane art, passed down generationally by clicks, grunts and drunken cave drawings on the wall of the garage.
Some tuning parts are available, but nobody I know in my area can tune one of these things. The owner is therefore probably left to choose between an expensive trip to somewhere far off, or going it alone with little support.. Which is a shame in the midst of this otherwise robust source of C4 information, completely covering every other aspect of the car.
I don't think it is owners unwilling to spend the money, either. I see people here spend inordinate amounts on less vital aspects of the car all the time.
Many of us could learn a great deal just from being exposed to discussions about tuning and the inner workings of the engine management system.
