cost of gen 7 vrs FAST system
looking at the fast it seems like ther's alot of junk you need to get to make it compatible (like crank senser, edist box) while the GEN 7 seems to be complete, or am i missing something
for the turbocharged ls1 what is the better value?
FAST Edist box: ~$300
FAST crank relay: ~$100
-------------------------------------------------------
~$2400
I believe the Gen7 is more than that, I think a Gen7 is $2800 or more with the wideband
I just bought a used Edist box for $200 I found a few of them out there.
is the $2400 have everything you need or are there other things like 3 bar map sensor or other add on sensors
whats your experiance so far with the Fast system John?
and i still need edit or hptuner for the stock PCM to change gear ratios clear unneeded codes right?

I am running a bank to bank FAST system, and no Edist. I am still using the factory pcm and harness and LS1 Edit to control my timing and my idle.
I am waiting for the FAST crank signal decoder box that would allow me to run the FAST as a total standalone. I am currently using a crank solution is not showing consistency for me at my power level.
I have been talking to Craig @ FAST about the crank part for four months, it should be out soon, but I have a lot more urgency than they do since I want to dial the car in at the track in early April.
Did I answer all your questions?
if your using edit to control your timing and idle, what is FAST doing
just controling fuel? and reading how much air is coming to aviod the MAF meter limits?
and how are you not using an Edist? i though the ls1 had to. or is that because your not controling timing?
do you plan on using the Edist? once you get your crank sensor?
When you go to standalone do your factory gauges and other things in the car work?
or do you have to switch to aftermarked gauges
what are the benifets of running a standalone over a piggyback?
I take it if i go stand alone i dont have to worry about codes for not having EVAC or No ABS, so i dont have to purchase edit or hptuner.
but will the alarm, locks and such still work?
thanks for the help John.

I am running a FAST b/b with no Edist at current. I am using the FAST to control fueling and LS1 Edit to control timing. I am running in speed density so my fueling for boost is working off of my 3 bar map sensor. You would need a 2 bar map sensor for your car. I don't know how Gen7 does it or maybe they add a map sensor too. Once FAST releases the crank signal decoder box, it's a splice-in deal... maybe a plugin. It will converter the factory 58x2? (I forget) signal into a 4x. I will then wire in the Edist and control it all thru the FAST. My gauges will all work except my speedo.
I have an extra 2 bar map sensor if you need one, I used it for a few dyno pulls but we went to a 3 bar map sensor.

Cool , thanks for your help.!!!
So at this point, it works, it cost around $2300.
Now I am going to use the new FAST crank signal decoder. That means I can control the timing thru the FAST system which is the way to go. I will be then removing the MAF. The MAF currently is still being used to report load to the pcm to affect timing.
A new Edist is $300, and the new Crank Signal Decoder is supposed to be around $100. So realistically you would be around $2600 new if you shop around. I have seen used FAST's for as little as $1500, and used Edists for as little as $200. You could get into a used FAST setup for as little as $2000 if you really look around. Make no mistake, the performance and responsiveness of a FAST system compared to a stock pcm is 10 times better. And you can make changes instantaneously while the car is running. And datalog. And it can make up to 25% fuel changes during a pass.
Okay, now it's my understanding that when I convert over, I could remove the stock pcm and harness but I will loose all the factory gauges. So I am researching what I would need to do to make them work. Worst case I could do aftermarket gauges. But I am more likely to run it as a piggyback since it's almost racing season and I can try aftermarket gauges in the late fall when I have more downtime.
With my setup, a few other things that you might not know. I am running a second IAT sensor, and a second coolant temp sensor. I'm guessing this is necessary as a standalone, but maybe once I do the Edist and the Crank Sig Dec I can remove those or they would be become unnecessary... I don't know but I will find out.
Which wide band does the fast use? Hence how much is a replacement?
email me if this looks like a possiblty.

so most likely my needs would keep it as a piggyback, with the controls to control fuel and timing.
i think im still aways from getting it, but hopefully next year i can fit it into my budget.
If I go standalone I lose tach and speedo. I already lost speedo when I went T400 (which can be addressed by adding a sensor to the T400) so I think I will go standalone once I have the car up and running with the other FAST parts.
