Big Stuff 3 would get my vote.

BS3. It comes with a complete LS1 Harness, and was designed to work with the LS1. Both the Gen7 and Fast have a few issues on the LS1.

XJGPN, what is the LS1 issue that gen7 has?

2FAST4U

Same here Gen7 is hands down the best oh and soon it will be even better! A little something with the FI guys in mind

I have the gen7 w/wideband and so far so good oh and I have the stock pcm and gauges in the car!

Do you still have the factory computer on board to communicate with the BCM. Or is it, take the whole harness out with computer and replace with big stuff 3. The reason I ask is cause I am doing a swap. Insted of making a harness or buying one for the LQ4. Then buying software to program it and then not a have a versitle enough setup for my turbo project. I would like to have something like big stuff3 to put on there and have a nice super clean install. Besids the fact that its a S-10 with a turbo, intercooler and more pipes then a pluming supply store, just sort of running out of room. $2295 is a pretty good price really considerring what you get. I was thinking of using MS but just don't like the idea of the timing control issues.

The high RPM miss issue... I know they were working on a solution, and for all I know it is fixed now... but when I was comparing the 3 not too long ago, it just seemed as though BS3 worked a little more seamlessley with the LS1 engine whereas there were a few hiccups when going with either FAST or Gen7. Take what I say with a grain of salt though as I don't have any firsthand experience with any of these standalones on an LS1, just from my own research it seemed that BS3 integrates slightly better... and the fact that it comes with a complete Harness for an LS1 makes it seem ideal for someone using the LS1 in an engine swap.

I have a friend that spins her Gen7 to 8500 RPM without issue on a SBC.... Jobs Work.

That being said, I prefer BS3.

Yes, I said "HER"... she can be found running 7's now.

The high rpm miss issue is LS1 specific... I hate defending my position more, since as I've already said, I haven't seen it personally. I just heard of a few instances of difficulties with both the FAST computer and the Gen7 surrounding crank trigger issues... I know these problems don't always happen, and I know that they will probably be solved soon. BS3 just seems to integrate with the LS1 ignition better than FAST or Gen7. I've used DFI on a friend's SBC, and I am about to help another friend do a FAST setup. They are all fine computers, and I really feel that the power you get out of any of the computers has a lot more to do with your tuning ability than which stand-alone you go with. So, I really don't think you can go wrong with any of them. Just in this case, the BS3 sounds fitting

PS- does that car have a Lenco? It looks vaguely familiar. I think I saw it at Jobs shop back in 99.

2FAST4U

Yes I have heard of that issue too. In fact MightyMouse had that problem long ago! But it isn't a problem with the Gen7 as much as the LS1. I have loged the data on many of my friends stock or moded cars and in every one seen missfires! I realy think it is a LS1 thing truck coils and good wires/pluges can help!

This is why I had a post about the new redesigned LS2 coils.

The BS3 will come with a harness that will plug and play with your LS sensors. You may need to change the MAP sensor plug for a 2,3 or 4 bar map for boost.
I have personally run 1500hp with truck coils.
I have personally run 8800 rpm with N2O and F car coils.

This system will fill all your needs.

Thanks Kurt, your alright!
Looks like I will be buying BS3 soon.
Maybe I will see you soon agian, when I head up with Zippy.

i never had a high rpm miss. i would lose spark under high load. this was directly and ONLY related to the POS moroso spark plug wires that i had on my car. the wires were so noisy that they shut down the coils.. something technical like that, ask craig at DFI

my car has now been to 6900rpm at over 800rwhp with it on stock 98 coils and stock wires no problems

Kurt,

Does BS3 have the ability to load different dwell tables? I assume it does since you are using it with both the F-body coils and the truck coils.

Thanks,
Andrew

Coil charge time in milliseconds is adjustable per RPM, although we use the same numbers for both coils.

Ok, I'm done doing research on this topic, just ordered BS3.

I know if I went with Accel or FAST I'd be kicking myself later after the project is finished.

Where did you order it from?

Boostaholic

iTrader: (4)

There are a number of vendors who have it, most don't "stock" it except W2W, Kurt said he was expecting some in about a week?

I ended up getting mine from LS1Speed because I was already making a big order from them, so I just rolled it into one, W2W has a better price though (About $50 less)

BS3 all the way. We run it on the Formula and I will be running it on my CE with the tranny control for my 4L80E. This is by far the best and most adaptable system out there. If you race your car. Get the replay. It is nice not having to take your laptop down the track with you. Plus the amount of inputs in can record is crazy. Check this out. Say you select to record RPM, BOOST, FUEL PRESSURE, TIMING, and TPS. Well lets say a month later your running your car and you notice your voltage is dropping during your pass. Even though you didn't select to record voltage a month ago. You can go back into that replay log and select it now and it will show you what it was. The system automatically records all connected inputs. You just decide what ones you want to see at that point in time.
Plus you will never receive the tech support that you can from BS3 compared to the others. John Meaney loves this stuff and is continuing to make the system better every day.
