Tunerpro RT $4F connection problems

Sounds good. So you think there is still some power left on the table?

I actually think the vacuum line was for my MAP. I'm not looking at it right now, but I just remember thinking that there was no way I wanted to mess with switching it around. I'll have to check the local bone yards.

Just so I get this right and make it easier on you, I'm going to type it all out and you can tell me if this is right. To adjust minimum air, I turn ignition on, connect pins A and B, unplug the IAC, start engine, turn down screw 1/4 turn, shut off engine, plug in IAC, start engine, make sure its in closed loop, rev engine, let it idle, shut off, reset ECM, repeat whole process.

I'll try the LD file tomorrow! As always, THANK YOU!

Vacuum for MAP is always there and center rear of TBI, between fuel lines.

IAC = no... your combining the proper way and my shortcut and got it all wrong!

Proper way is engine toatllly warmed up. Turn off, cross A and B turn key on and walk around to pull plug off IAC, it will be closed by the time you get there. Remove A and B, start engine and wait for Closed Loop, adjust idle to 100 RPM below setting in bin file. Engine off, plug in IAC, clear codes. Should end up 20 to 40 IAC counts CL idle.

My way, or I should say another way I found that works is while warmed up CL idle and looking at Scan Tool/TunerPro and IAC is low or high, so if low/no counts close throttle blades, if high, open throttle blades. 1/4 turn, turn key off 10 seconds, this clears the power off which is usually 5 seconds and resets TPS to 0 %, start engine and rev till closed loop, let idle and check IAC. Rinse Repeat. I can do other things while doing this, usually have my next few steps/checks already planned, don't get to close to me while working on one, I may change dierection and knock you down!

Haha I'll remember to stay out of your way if you are adjusting your idle!

Glad I asked about the methodology of getting that adjusted. I got mine adjusted so I have about 20 iac counts. I had to readjust my TPS because it didn't reset itself. I was also able to order my burn2 today so I'll finally be able to figure out what my bin looks like.

In that data log I posted on here, why is it that there are only values in one of the MAP columns? Is something not right with my data logging that it didn't fill in all the boxes? Also can you look at your spark advance to see what the timing is ACTUALLY doing or can you just look at the bin and see what its SUPPOSED to be doing?

TPS voltage will not reset. It is the TPS% that resets in the ECM to 0.

Well the reason the BLM history table was only doing one line was this ALDL data stream only has MAP voltage, the value for MAP kpa is a conversion from voltage and it was wrong. I fixed it.

But the BLM history tables in HD or LD do not match the fuel VE table so they need to be redone. Wish I had time but not going to happen till fall! Here's a write up I did on how to make them and you can readjust to match the VE table.

There is also no spark advance in the ALDL data stream so best way to see where you are in bin is to use data tracing, I set up the spark table, take a look here on how to use it and make it work for other items.

I just looked at a $4F bin file Main Fuel VE table and it is by far the worst thing I have ever seen in my life!!! Click on graph to see? The GM engineer who built the fueling for this should be hunted down and shot! Main Spark is also a disaster... I know what we have today is better then what they had then, but this is ridiculas! Rocky Mountains are a flat plain compared to these...

Maybe while I'm in the hospital with no internet for three weeks I will do a write up on how to build a smooth spark and fuel table to start with...

Hospital for 3 weeks? I hope everything is OK!? Thanks for fixing the file!

Well hopefully the guy that burned my chip worked out my fuel table but in all reality, who knows what he did. Hopefully my burn2 will be here in a couple of days so I can have a look and upload it on here, of course you will probably be stuck in the hospital when I get it so I will try to patiently wait!

With my lack of knowledge, I'm not sure what you mean by "the BLM history tables in HD or LD do not match the fuel VE table so they need to be redone" but I'm always up for learning so I'll look into it.

I hope everything goes well in the hospital and thank you so much for all your help!

Lots of guys to help while I'm sidetracked. Read the history table thread I made and it'll get you into what is possible with TunerPro. Basics are done! Just that MAP and RPM do not match VE table, once you read and look you'll see what I mean.

I got my Burn 2 in the mail today. I hooked up my chip and tried loading my bin with flash & burn and then opening it with tunerpro but when I open it with TP it doesn't show that there is anything on the chip. All my numbers are 0. Do I need to change my chip and buffer addressing? Right now my chip is 000000 to 00FFFF and the buffering is 000000 to 000000.
