F.A.S.T.questions Who all here is using the FAST system. I kind of on the edge here. I don't know if I want to go with the Bank to Bank or the Sequential. I talk to Cartek and they recomened to just use the Bank to Bank with there crank-trigger conveter and have the stocker do the timming. Anybody running FAST on their car and do they use the car as a daily driver? Does the car stay streetable, and to anybody using the bank to bank...what kind of gas mileage do you get?
Thanks
Gary

Re: F.A.S.T.questions read the post about the big turbo motors. Brady and the others use bank2bank. apparently theres no real need for sequential. get the wbo2 though. fast makes an edist for your 8 coils, but I don't know now the pcm gets the cam signal...not that technical. call sean at MMT. he had fast on his LS1.
Re: F.A.S.T.questions about gas mileage..
I went on the power tour this year and got 19-20mpg!! (3000 miles in 10 days) I was ecstatic. That's with a TH400, 3.50 gears and 30" tires..
As Ryan said, it's bank/bank. It starts and idles fine with 83# injectors. On board wideband O2 sensor is invaluable..

Re: F.A.S.T.questions 
Hooked on phonics worked for me 
Thanks guys, big help in making my decision. I was worried that bank to bank would eat gas like crazy. I want the car to make crazy power on demand but still be able to be driven on a 500 mile road trip. I'll probably go with the bank to bank do to financial reasons. When I was talking to the cartek guys they told me it's a real headache to set up the sequential because of the cam position sensor.

Re: F.A.S.T.questions Another vote for the bank to bank setup - it's not that bad to setup the sequential if you have access to an oscilloscope, but it is not really worth it either. Emissions is the big reason to do sequential (HC), the other benefits are very small.

Gary, it's not difficult to set up a sequential box, but our converter box is not synchronized with the cam so it can't be done with our converter box. You can run a sequential box with it, but the benefits of a sequential would be null since it's not synchronized to the timing event of any one cylinder. The only benefit of the sequential in this case would be for the sake of maintaining better fuel rail pressure stability and not firing all the injectors simultaneously like on a batch fire system. Bank to bank systems address this problem and are almost as good as sequential units handling this fuel instability problem with out the extra complexity and expense of a sequential.
How many of you would be interested in a synchronized version of my crank trigger box to use with eDIST?
