JET Memcal adapter: Difference between 305 and 350?
A bought a used Speed Density ECM from a 91 Transam (305 TPI). To my surprise it came with a JET Memcal adapter and chip. I will be using this on a 383 Superram. I believe there are 3 chips...one is the PROM, the others are limp home chips and ESC Filter. My question....are the limp home chip and ESC filter the same for any engine?

Use the latest memcal to base your work on. They make slight changes from time to time, and it works out best starting with a given rather then a maybe.
If your working on a SD 350 an AUJP is what you want to start with.

Differ from what exactly? SD 305 and SD 350? MAF to SD? V6 to V8? TBI to TPI?
Also, is this a "piggy back" Jet carrier that you plug into your Stock Eprom so the ESC circuitry flows through?
A stock SD 305 memcal can work (though not optimally) on an SD 350 car. There is a difference in the knock sensors which affects the ESC circuitry. Your best to get a stock Memcal that is the closest to your car. That would be an SD 350, since GM never made a 383.

Glenn....read the message..not the topic...its the difference in the two chips (besides the PROM) that im asking about. I will be using a 383 SuperRam Speed Density setup...and I have a JET memcal...I will program a custom PROM...but the other 2 chips I am wondering if they are different....and i think Grumpy answered the question. Thanks
