Good Afternoon all,

I am looking to get a chip burned for my 1988 gmc k1500 auto w/ 350.
Does anyone currently offer this service?

It is stock.
I ordered a egr block plate and need to tune out the egr setting.
I also ordered a smog delete pulley to get ride of that. I will plug up the holes in manifolds.

I was getting 11mpg, so after my tune up I hope to be a bit better.
I did platinum ac delco plugs, wires, new map, iac, coolant sensor and bunch other maintenance.

Thank you,
Ron

:welcome:

If you post the chip information or broadcast code (BCC) http://www.gearhead-efi.com/BCCFind/ there is a good chance myself or another gearhead-efi member can help you. Sometimes the BCC is not in the gearhead-efi library: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?304-1227747-ECM-Information-42

To disable a functions like the EGR and Smog Pump, the chip is programmed so the EGR and / or Smog Pump will be enabled "ON" at vehicle speeds greater than 255 MPH or enabled "ON" when the engine temperature is greater than 305 degrees Fahrenheit. Sometimes a "Hack" is required for the chip programming to disable the EGR because the chip programming does not allow speeds of 255 MPH or temperatures of 305 Fahrenheit.

I found 0055 on the type of chip pictured to the right in the link provided.
Is that enough characters? I took picture of cover and board. I can recheck in the am if needed.

Thank you for your reply.

Unfortunately, the BCC will be aliphatic not numeric. Usually the aliphatic BCC is something like AUMR, ARJT, or AMUL.

As Dave w mentioned 4 letter code on the ecm Iirc it also will be on silver tape affixed to the prom provided everything is stock and unmolested.

I found it, unfortunately had to clip the plastic bar blocking it. It is AMUR.
hopefully I can reattach that piece or it will be fine without

Ebay sometimes has used TBI Chips with code AMUR: https://www.ebay.com/itm/Prom-Chip-AMUR-1987-1993-Chevy-GMC-5-7L-350-TBI-700R4-MD8-1227747-EPROM-16120054/312694366617?hash=item48ce096199:g:yo8AAOSwf4BccDK e

There are actually two parts required for the TBI Chip, the EPROM and the plastic EPROM holder. Basically EPROM holders are only available used.

awesomeThank you very much for the for the link.

Do you know of anyone who burns these chips? In my research I found some older sites and a couple people did not respond, could be holiday related though.

I looked into burning my own, but I am not planning on modding anytime soon. The last owner unplugged the emissions but did not tune out. I have a egr block off coming and smog delete pulley. Trying to get truck running smoother.
