when doing a swap has anyone used the FAST LS conversion self tuning kit? http://www.fuelairspark.com/fas/efi-...l-pack-engines

if so what are pros and cons...im swapping lq9 into a 81 firebird.

Also, I am new to the efi world with all my experience in sbc carb engines. any input on buildinga budget lq9 would be highly appreciated.

I would go with the Holley HP. It too has self-learn fuel maps, but has built in ignition for the LS. The FAST has to use a separate ignition driver. I like having everything integrated.

The holley will learn but I ended up taking mine to a tuner anyway just to get off on the right foot. Probably not necessary.

The trick with the holley is to turn on the learn function and drive the car a little. Then transfer the data from the learn table over to the base fuel map. It's as easy as typing numbers into little boxes lol. After about 300 miles and 2 or 3 transfers the car will run like it was factory tuned. The downfall is you have to tune the idle yourself. I did a lot of reading before hand, but it it's really easy to do. Took me about 30 mins and idle was solid.

The Holley manuals are a good start and also the Holley EFI forum.

I'm in the process of trying to decide between the Holley and Fast 2.0 for a LS Engine as well.

It's a tough decision.
Let me know what you decide on.

Hi Andrew!! Lol.
