Welcome to the site. Lots of folks here are willing to help if you have specific questions.
Ahh... Yes, the blue ones are different. ;)
The first year trucks were set up a little differently. The relays weren't all installed on the RH side of the cab in a neat row. The fuse holder is...
It really sounds like you love your Jeep and it seems like an extremely capable rig. I have gifted a 95 square eye to my son and it appears we are building a street Jeep. A good Jeep build would be...
Are you working with a square body R/V harness or the K truck harness? R/V had some different connectors and used some different wire colors.
There are tools to help remove the ecu pins. They...
Well, it's not quite that way. The ecm will still deliver injector pulses and spark pulses. The challenge is in how the ecm uses the information. If a V8 engine is spinning at 2000 RPM it's...
Yes, you're approved. My apologies for the extended wait.
As someone responsible for trying to prevent spammers who love posting bad links to illegal medications and other products, I'd like to...
We had one when I left dealer land in ~'97. Although Tech1 kept talking with OBDII, we really only used the Tech2.
How old?
Welcome! Glad we can help. What are you working on?
Hello. Welcome.
Love the sportside truck. They don't build them the same anymore.
Hello,
HPTuners is locked to your VIN and maybe other things as well. You may have to manually enter values from a 4.8 calibration into your pcm. It would help if you can identify your operating...
Even GM wasn't above using an adapter to run TBI. The early Big block TBI trucks used a water heated adapter on a carbureted TBI manifold.
If it runs well, stay with it!
Welcome to the forum!
Best place to start is with free stuff. It can handle an LS swap with no issues.
Those old Z cars are fun. I used to have a 240 back when Scarabs were still new enough...
For reference, 1995 and newer J cars (Cavalier and Sunfire) use an external ecm as pictured above. 1993-1994 J cars used an interior mounted ecm. V6 J cars from 93 and 94 actually used a 1227730.
Hi Tom,
Another potential source for 68HC11 OBDII ecm's is here:

Daewoo used 1.8L, 2.0L, and 2.2L GM engines and...
I would not use this logic when looking at calibrations. Calibrations can be released that solve specific issues in certain vehicles but are not appropriate for most vehicles.
Sometimes van...
Does this look right?

Yes! Very happy to hear it helped. Thank you for taking time to post the conclusion.
Thank you! I just used this.
Interesting. Did you use $900A as the address in Tunerpro? You may not be changing the MASK ID. I believe the correct address to set the "Experimental" Mask ID would be $8000A?
Hi,
I love projects like this.
Ok, in deference to In-Tech and his far greater experience than mine, I believe pressurizing the throttle body will expose the FPR to boost. The factory...
Maybe, yes. Check the size / number on the chip. At times GM used larger chips and burned the file into the highest addresses. Try changing the start address for reading to $8000. The file you...
You're very welcome. There are disassemblies on the page linked above. here. As Dave W noted, the filenames that start with B are actually $D8.
DRAC produces a 2000 Pulse Per Mile signal. ...
I'm unsure what you're asking. This picture shows waves similar to what the GM REF and EST will show if scoped while the engine is running. The top signal is from the pickup coil to the ignition...
Interesting... $85 / $D8 have the ability to guess at which sensor type is installed. The data word at $0043 contains a status bit for the type of sensor currently selected. If code is set to...
