Fuel injection
 

Ok, so many questions...some of which may have already been answered, so if you have a link to other pages...then lead me on to them please.

I am stepping up into the FI fun bag. I have LS1 engines which are currently run through a Fast management system. the Cavalier i just purchased has the Big Stuff system.

So, i have two full systems (ok i would need to buy the engine harness for the big stuff, but the cost of that is not in the mix of my decission of which to use).

I have read here the benifits of both manufacturers, does anyone have the cons of either manufacturer and/or system. the LS1 has been running fine on the fast system, but which ever system i choose i will be learning the system and tuning myself until a time of which i see i can go no further and will look to a tuner for assistance.

I also wonder about dynoing a FI engine. My local dyno shop ids discussion the move towards updating their dyno for FI, but until all this done am i limited to adding a carb and regualr intake for dynoing purposes? Once the dyno is set for FI i would assume i bring my FI computer and my lap top so the changes and mods are on my system?


your thoughts and comments are appreciated.
Regards
Ian

The only change required would be the fuel pump and fuel regulator, and I highly recommend running the fuel regulator you are going to use on the car for this anyway. Don't waste your time with a carb just for Dyno purposes as the camshaft and intake should be tuned for FI and it won't give relevant results.

I have tune most systems used. I much prefer the FAST.

I have experience with EFI systems on my dyno.

As was already said, no valid data will be had without the parts you run. Period.

Granted the set-up time is longer, extra plumbing and wiring, but all is good.

Bring 'em down.

As stated above, add high pressure pump and regulator and make some pulls. Works great.
