okay, I have all that (as I just mentioned in my other thread, it is possible I wasn't using the .bin from the old EPROM).

I have set up the AutoProm as you mentioned, it beeps just fine. It...

Well.......

I copied the original tune from the original chip like it says to do so with the offsets. Programmed chip, and it works. However, I suppose it is posible that I forgot to upload that...

yeah, I have the AutoProm. I think I understand. I didn't realize I had to save the Bin, I thought it was live when you click the Update button. Which is also why I didn't know I would need to...

can I do that while in emulation/datalogging mode?

I'm sorry these are dumb questions!

alright, I can find the tables now (I didn't see tht it is projected behind the dashbord.)


I looked at a few tables and they aren't populated? Why aren't the populated with the current cal's...

okay, i searched an old thread and saw the parameter tree > category > patches > hacks

It says change to 0067. I think I did that? I dont' know it doesn't seem to be working.

alright, that is what I assumed. But, where do I get the hack? I'd really like to see spark advance.

For some reason it didn't have the right ADX file in there. I put the updated one in and all the variables are there.

However, when I click on them, they don't do anything. I'll figure that part...

okay so:

I found the new ADX files and XDF files and uploaded them and they work...kind of.

Files: V5.2 ADX and 5.9.3 XDF


There's:

Spark advance from hack*

so, lesson learned - never assume someone else did the right job.

I knew the problem lied in the PCM so I started digging around. The connector for the PCM had some really caked in there gunk,...

oops, i meant '7747 you're right.

Where can I find the comments on the hack so I can change it?

Thanks!

forgive my ignorance, what do you mean by "what code"?

its a '90 TBI truck...although I don't know if that tells you anything.

is there an ADX file for the '7727 that shows spark advance?

so, more of the backstory:

They had the original ECM (which also was a '7747) in the truck with one of the many chips they have that someone tried to desktop tune (that never worked) and someone...

Mark - Thanks for being awesome!

The driver was too new. I regressed to the one suggested. I'll try it now and see what happens.

EDIT: So, same deal it shows connected, but it will not read...

well, I kind of spoke too soon. It connected both, but it was not reading live data - all the values were just staying constant.

To answer your question though, the CEL works in the sense that it...

Okay. I just got both connected. Awesome!

I've done what you said. I moved both switches to the in-board side. The emulation part works, when I click the "acquire data connect/disconnect" button. The message indicator bar at the bottom...

I suppose I meant copying. Copying the cal from the 24 pin chip onto the new 28 pin chip per the intructions you linked me, using the offset. But, along the same lines, can a 24 pin chip be...

Okay guys, I've gotten to mess with it today, and now I need some questions answered.

First, will the truck start and drive without a chip?

I'm fairly certain I figured out how to read the...

This is good information guys thanks.

I think he won't understand about the ECM issue until we try it with this one and he sees that it isn't working. So I'm sure i'm going to have to try it.
...

I looked on the moates site and I didn't see those instructions! Thanks for posting that link.

What your said after that implies to my naivete that you can do it like I said and not solder it? Or...

Hi guys.

So, long story short. I'm helping my uncle (finally) tune his 90 tbi (originally) suburban that he converted to the old edelbrock efi bolt on deal.....like 12 years ago. The guys burned...
