If I go the route im planning, I will have a complete N* drop out drive train(I believe its from a 94), so I'll have the wiring and ECM and I have a couple of the 7730 ECMs laying around
Im planning on bolting it to a Getrag, but I think you already said above it was for a standard tranny right?
Other than ECM all I really need is the flywheel and a good bit of metal fab work right? Ive done 3.4DOHC turbo's and 3.8SC's as well as half a dozen 2.8's so the fab work is not a big deal.
Im not sure yet, as of right now Im trying to decide whether I should rebuild the turbo 3.4DOHC in it, or go N* or 3.8SC. I can get the dropout N* for $400 so thats a big selling point....
Hey, how compatable would your program be with a turbo? which year N*'s are MAF? All?

The chip is $50. It will work with a getrag. The computer will not work with a 94 northstar. You need the 96+ intake(or TB) for it to work, which is a PITA to install on a 94. I went through the steps in another northstar thread. Basically it involves drilling and tapping the heads. Not for the faint of heart.
Turbo is not a problem, but it hasn't been done before, so expect speed bumps.
96-99 are MAF and are plug and play with this computer and harness.

what ever happened to the paddle shifting for the northstar 4t80E who would I look into gettting that thing from? I will probably use the comp to deal with the shifting till I can get the paddle shifter. any info on that?

well what are you doing messing around on here?? j/k Git R Dunn man... I was talking about the company that made them... I saw a post that had them on it and was kinda intrigued on how it all went together. do you know the post I am talking about... if you could make up something for the 4T80E then I would GLADLY give you the business...

It looks like it's almost a done deal in that I will be swapping my 3800SC for a 97 Aurora 4.0. In the distant future, it will get a small turbo. My biggest question is what option do I have for the trans control? For the time being, I'll be using the 4T80. Will this ECM control the trans? You were working on a trans controller. Did you finish it? Will it work on the 4T80? Or am I going to have to use the stock ECM?

The ECM won't control a transmission. The transmission controller I built is finished, but I sold all the ones I had.... don't have parts to build any more, it would cost too much to have more boards made. If you were really interested... and willing to pay a premium to help offset the board costs, I could probably be convinced to put together another small run....

I noticed you have an ALDL plug wired in there also, but what codes would be left to check for, once the egr and all that "extra" stuf has hit the dumpster? Also, if I hooked up my Auto-X-Ray to it, what car would I tell it that it was looking at?

Why yes, yes you may. (Actually I'm surprised you don't have it already! Maybe tomorrow...)
Correct on the ALDL plug... It works like any other GM computer, it'll let you know if your MAP or TPS readings are off the charts... Coolant temp... etc. You can use the ol' paperclip trick to pull codes.

WOW! $500 for a system using factory components that is 98% plug and play! That is truly a steal! Kudos to you Ryan, we may have to talk in the near future.

Ryan, how does your ECM setup take to aftermarket cams and/or ported/polished heads and valve jobs? Would it need to be re-tuned, or would it figgure itself out?
If it would need to be re-tuned, what software/tools would I need to do it myself?
Also, I've got the N* harness. Would you supply whatever other connectors I need, the programmed ECM and schematics and basic instructions so I could do the wiring myself? (I'm rather wiring savy, but just lazy )

It can adjust for minor differences between engines, but not cam swaps or anything major like that.
I include a freeware copy of tunerpro with the definition file. To tune the computer, you will need an ALDL interface, and an EPROM burner. The burner is about $30 on ebay, the interface is about $40 ready-made... you can also build one yourself for about $20 if you're savy.
I can supply whatever parts you need.

Ryan I am just waiting to get my Holley back and then it will go up on Ebay and will send you the money for your setup.
How much would it cost to get some boards made up and how many do you have to get made at a time?? I mean crap TCI wants $658 and PCS wants $700 then $150 for the harness.

I don't know..... I have 2 prototype boards for my "next generation" TCM that could be reprogrammed with the old code... I could assemble and sell you one, I'd have to get back to you on a cost. Unfortunately it means the old install instructions won't match, so I'd have to redo those as well...

Another question... Will the 7730 run enough of the emissions equipment to allow it to pass a sniffer test? Although Georgia doesn't do a visual inspection, other than looking for a cat, it does test for NOx. Without a working EGR system of some sort, it's not likely it will pass. I'm pretty sure the same situation will hold true in other places.
I'm not planning on doing another swap anytime soon, but this will no doubt add another option.

No news on the 2000 setup. Nobody has given me the info I need from a service manual.
Emissions are "disabled". However, if one were inclined, you could install an EGR from an early 90's w-body (which may or may not need an adapter plate). However, I have not tuned any engines with an EGR before, so I'm not sure how difficult a task it would be once you installed one. In short - you can do it, but it might take a while to "get right".

I have a stand alone GM Transmission controller out of a diesel pickup for the 4L80E. I don't know if you know anything about them but seeing as how you did the work on the GM Computer to make it work on the Northstar, maybe this would be an option for you to use instead of starting from scratch with a whole new TCM everytime?

The coil on plug setup IS the problem. The 2000 ECM controls the ignition directly - there is no ignition module to interpret the crank sensors, and fire the coils.
Or are you asking if those engines were COP? If so- yes.

Interesting thought, but it's a PITA to reverse engineer something. The next gen TCM will be the "end all" of TCM's. It will be programmable, and offer automatic shifting. So in that respect, it will be the "last".

what if you added a wheel to the end of the crank, and a trigger. Could you then use one pf the ecm setups if I were to ditch the coil on plug setup, and use the reguar DIS on the older motor?
Sure, you could do that today. What I'd like to research is whether you can use the stock trigger system. External crank triggers aren't all that elegant of a solution. Plus you have the problem of them getting damaged or muddy or whatever...

He also said that he thinks there are 2 control modules. One for each bank.
A wheel, or a northstar wheel? You need a northstar wheel. Anything else won't work.
I don't know what we're talking about anymore, but no northstar has 2 control modules. The <99 uses one ignition module that interprets the crank signals and fires the 4 coil packs. The 2000+ has NO ignition module. It has 4 coils on each bank. They are directly controlled by the ECM like an LS1.
