[Gmecm] TBI for 455 Olds - 454 BINs

Wade...

Just wanted to chime in one more time.

Regarding the Dynamic EFI EBL ECM setup, this is a great way to be able to actually tune the ECM yourself.
In fact Robert Rauscher makes it easy, as it has a self-tuning function built in, and also has data logging as part of his software.

You can just send him your ECM to convert, and if you ask nicely, he can load up a starter BIN for you.

If you do not wish to go this route, if you need an EPROM burned, by now I think you see there are several of us with that capability.

BUT, you really don't need to send us the ECM.
All we would need is your present EPROM from the ECM (if that).

As for me, the 2732s are so cheap, I would just burn you one and send it to you for cost of postage.  The EPROMs are only around $2.50 apiece these days, and I have several.

But my recommendation is you visit the Dynamic EFI site and puruse what Bob Rauscher has to offer.

You can also email Bob and discuss what you are trying to do, and he is real helpful.

OK.  I guess it's my turn after finally getting to read the posts.

 

Been having to deal with issues at home - my wife has MS and developed a bad
case of gall bladder (or what the preliminary indications are - more tests
on Thursday and Friday).  We live in eastern Tennessee so - getting anywhere
takes an hour or more.  HA.  But we love it here in the mountains.

 

Anyway - here are a few things to bring up to date for the group (many
thanks to all who have the time to devote to this)  J

 

The engine is a stock 455 from 1976.  It is low compression, but high torque
and runs very well as is.  It is a stock 4-bbl version out of a Delta 98.

 

Transmission Lockup - I currently control this via a manual switch - it's a
lot more efficient for me given the cruising that we do.

 

The Trans was built to stand up to the torque of the 455 .  It currently has
a gear driven speedo.

 

The camshaft will remain the same - I was told that it was stock.  I am
probably going to rebuild the engine sometime this next winter, but for now,
the cam is stock.

 

I DO NOT have anything ESC or Knock related to a BBC.  All I currently have
are those items for 5.7s and 305s.

 

As far as running the ESC and Knock - I am not a against it but if it is a
major headache, then I could go a different route.

 

Distributor - currently running a stock HEI style with in-cap coil.  I read
where the Howell uses a lead from the Tach output to sense engine RPM.  I am
unsure if this substitutes for the ECM needing to know how fast the car is
going but since I don't need to have the ECM lockup the torque converter,
this is optional as well.

 

Given this info - I will take "off-forum" any further info needed if that is
what someone wants to do.  

 

I do not have the means to burn a chip but would be more than willing to
send my ECM to anyone that would.  As well as take care of their time with
$$.

 

I certainly can't express enough gratitude to everyone responding to this
project.  I knew that I couldn't just bolt on the TBI and related controls
and use the 5.7 tune, so this is great info.

 

It took me a little while to read thru the posts and I may have missed one,
but I'm going to print them all out so I can reference them.

 

Looking forward to hearing from you all.

 

Wade.
