That is good info about the ECM and Gen 4. I'll have to take a close look at this engine before I make a decision. THANK YOU!!

Thanks! I was looking at the LS droid page and there is something about discontinuing support for some hardware??? Is PCM Hammer still in a BETA stage? I'm just a little confused I guess. Are...

OK. Thank you. I'll look at both of those.

Are they easy to use. I'm not even close to being a computer nerd! lol Well i guess I can learn but old dogs take a long time to do so! haha I...

I've decided I'm NOT going to rebuild the 5.7 small block in my 90 C1500. Instead I plan on swapping a LS into it.

My question is... Will Tuner Pro RT directly flash the ECM (OBD II) of choice...

I decided to purchase a ready made cable. i got mine from 1320 Electronics LLC out of Cocoa Fl. (www.1320electronics.com) This cable has a box in between the OBD1 port and the PC. Look at the web...

There has to be a place to drill and tap for a fitting as tayto mentioned. This would be my solution. Maybe drill and tap where the OEM brake booster location would be??

Because I'm a little slow and ride the short buss more often than I like.....

I have a 1990 C1500 with a 5.7 and TBI. As far as I know nothing has been done to the engine or computer.

I want...

Will give the remote access a try. Otherwise I'll be in WAY over my head! Still a laptop will be the best. Maybe I can talk the wife into a new laptop???? She has mentioned it!

Thanks Dave!

Well first I need a lap top with windows. Quite sure a chromebook won't cut it??? Guess i could try it though. Ya never know for sure.

Downloaded a copy of TP on to my PC to look at and read...

Dave w. Thanks in advance for the data logging help when I get there. I assume running the engine with the stock chip "causes no harm" it just will not be optimum and may hurt mileage and...

All I have is a Chromebook which is the biggest POS I've ever used. I've looked a little at the data logging so will have to look closer. That is kind of beyond me at the moment as I get along with...

I know I will be close to that 9.5 CR. When I worked on the heads my work in the combustion chamber amounted to smoothing and rounding off the big lump of the spark plug boss, cleaning up and...

As the title states I want to rebuild my "90" C1500 5.7. I'm not looking for high performance. I just want a nice clean running engine with a possible boost in mileage. What I propose to do.
...

Thanks Dave! My goal is to have a nice clean running engine with hopefully a little better mileage. The cracked head resulted in a dry cylinder that made for a dry piston ring and wore slightly...

I purchased a 1990 C1500 about six months ago. So far it has been a challenge with finding a cracked head, water pump shedding its impeller, fried ICM and thermostats. My intention is to build a new...
