Can the 8062 be flashed ? Is the any compatibilty of componets between a 8062 and a 7427 ?
The 1228062 is $4E and can burn a chip for them. We have a $4E info thread:

It's basically a 1227747 C3 160 Baud ECM. If your trying to swap most all the parts on motor are same except the ECM and plugs. We have a thread how to rewire the 1227747 to 16197427. There's some details below:

What are you trying to do?
I have a 87 S10 blazer with a 3.4 gm crate engine,auto and the stock [?] ecm. I have a few mods:4.3 tbi,freeflow exhaust[not hedders] and will add the caddy cold air intake.I assume I could pick up a little power and or economy with a tune.Right now I have the stock 87/2.8 ecm in it. I have a spare 8062 [4.3] and the 7427 I just picked up.If one of the other ecm's will work I will save the 7427 for another project,I'm here to learn.
It will work and would be easier to use what's there. Also a little easier to learn and tune on.
BUT! The 16197427 is a much better PCM.
What program do I need to open these files ?
Never mind,looks like Epadlite is working.
Yeah but you'll need TunerPro RT to use them. Open them in TunerPro and find your bin as well, then you'll get a better look at tuning software.

Free but we frown on those who don't pay the $39 donation/registration. This software is WAY better then comparable costing hundreds of dollars.
No problem if I use it I'll be more than happy to donate.At this point I wouldn't know where to start.
For the above application should I have gotten a 7427 out of a vehicle with a specific size engine or does it matter ?
ECM vs. displacement doesn't not really matter. However proper memcal for cylinder count and knock module does make some difference. For your application one from a 4.3V6 TBI/CPI would probably work well.

What Greg is saying is inside the 16197427 PCM there is a Memcal. On the memcal is the chip with bin file you tune, then there's a netres chip and a knock module. You can tune a chip but you can't tune a netres or knock module they should come from like engine.Quote:

Don't even really need to open the PCM except to make sure the BCC on the memcal matches the the tag on the outside of the PCM.
Check this out....

Thanks that's really handy,I confirmed that the 7427 is for a 5.7 engine but was surprised to find the 8062 was for a 2.8,I have stripped more than a few S10 in my day it gets confusing if you don't mark stuff.
