I am looking for a stock Bin file for an 87 5.7 TPI with 700R4 out of a camaro. I believe it is an ABYA bin. Can anyone verify that for me? I have looked at several sites, including Moates, diy-efi as well as eecis. Does anyone know where I can fine one? Also, I am looking for the $32B XDF file for TunerPro. Can anyone tell me where I can fine one?

 

You MIGHT get lucky here:

Moates has the $32B definition, but its called a Binary Editor File under Tunerpro XDF Files.

The only documentation I could find for a stock BCC code for F body 5.7 L TPI are:

ABWN auto 3.27 gear federal emissions
ABWT auto 3.27 gear federal emissions
ABWW auto 2.73 gear federal emissions

Moates has an ABWT in the stock binaries section. If you burn it to a chip and scan it with tunerpro or Winaldl it should say 8201 under prom ID.

 

Lucid,

Thanks for the info. I got on Moates site and was able to find what I needed.

Another question comes to mind though. Does anyone know what the difference is between federal emissions and California emissions? I need to meet California requirements and I'm not sure how much difference there is between the two standards.

 

In general they run less timing a little richer for the Cali emissions. This lowers the HC & NOX levels. Needing to meet Cali emissions I would start with a Cali calibration. Then leave the speeds/loads where the emissions is checked alone.

RBob.

 

That raises two questions: What bin would I be looking for to be California Emissions compliant? And any idea where I can find one at?

 

I had another thought on this subject. Could I get a $6E mask for my smog test? If so, can I change the prom id to match what would show on an 87, or is that even necessary? Also, again, which California smog emissions bin would I use?

 

This page shows a lot of the Prom BCC codes:

I am not going to say ARAP wouldnt work in your project but there are a lot of things that you will need to change to make it work. Its for a stock aluminum headed engine.

The spark tables are really aggressive, the EGR is controlled differently, the startup fueling is less, and a whole bunch of other differences.

In your case, it maybe easier to find a California Emissions Fbody BIN.

Ebay, craigslist? Have you posted up in the california section to see if anyone has a Cali emissions Memcal?

 

Great idea on the Craig's List. I never even thought about that. I will take a look into that today.

I looked at the chevythunder site and they list a lot of California Emissions proms for the 305, but nothing for the 350. I think I will shoot them an email as well and see if they have any further insight that can help me out.

Thanks for the possible new leads Lucid.

 

After quite extensive research over the past couple of days, including speaking with a PROM burning company I have worked with in the past, I have been told there were no California Specific Emissions settings on the 1987 5.7 motor. The 5.0 had specific settings, but the 5.7 used the Federal Emissions settings. As a final check, is anyone aware of anything different?
