I was wondering if anyone has ever used a LS1 computer on a Gen-I SBC. I think it would be a nice upgrade to the 730. It is flashable and uses coil packs instead of a distributor. I am not sure how the LS1 computer measures RPM’s crank sensor?

 

If you have any close personal friends that work at the CIA, maybe they can hac the security protocol and then maybe find someone to reverse engineer the code. Or just go out and spend some rediciulous amount of money for an editor.

While Windows, and the EPA have pretty much trained people into feature creep, their really isn't any need for the trick of the week in ecms.

If you want to engineer a cam synch pulse, then you can use an eDIST to run coil near plugs on your 3rd Gen. F.A.S.T. makes it, BTW I run it on my lil 6, and it seems worth while.

 

I am not sure what you are saying. You saying it’s not worth the money to pay for the editing software for the LS1 computer just to have the benefits of the LS1 computer setup?


Excuse my ignorance but can you explain what you mean.

 

Using an LS1 pcm over a 730 won't gain you a thing.

A 486/25 is 25 times as much speed for what an engine needs. Using a Pent III is just massive overkill.

There's only one LS1 editor and the beginner package is like $2,500.

 

I would not use the LS1 computer because it has a faster processor, if it even does, I don’t know. I would use it because it uses coil packs instead of a distributor, the tables support higher RPM tuning, you can flash bins onto it (Big Plus), it has a second fan output (can be updated using code change on the 730).

Another note, LS1 editing software is $550 at http://www.carputing.com. This is way too much but Tunercar is coming out with cheaper editing software.

Anyone ever put a LS1 computer on any engine other then a LS1? Also how does it measure RPM’s? A magnetic crank pickup?

 

1. Add a F.A.S.T. eDist for $300, will run coil packs off a 730.
2. maybe...
3. with a 29at256, not a real big deal.
4. yup.

still have $250 for udder stuff....

IIRC the LS1 has several pickups that need synched back to the PCM.

Oh yeah.... might as well shimmy up to the bar and get a 4L60E too....

 

I did some research on the eDist Electronic Distributor. My question is now what type of trigger do you have to use with it. There is like 100 different crank and cam triggers out there. Also does the eDist Electronic Distributor unit still allow the 730 to control spark advance? Or will you have to program the eDist unit separately everything you want to change your timing tables?

 

I know the feeling, not a lot of info from FAST on it. However, I know of folks successfully using it on both a DIS system (w/hall effect sensors) and '730 PFI system (with the regular HEI module for crank and an added hall effect sensor for cam).

In both cases the EST signals (from the ECM) are passed through to the coils. In this regard the ECM still controls the timing and dwell. There is no spark curve timing to program into the eDIST.

If starting with a distributor it becomes easy to add the cam sensor to it as the rotor and cap become redundant.

RBob.

 

It intercepts the EST line from the ECM.
Think of it as just a switch that points the point signal to the right coil to fire. It does nothing to alter the timing.

But it does need the addition of a Cam Synch signal.

 

A Romulator makes that moot.

If you want CNP, don't forget it's $30 +- for coils, in addition to everything else. And no *standard* plug wire end at the coil will work.
