Spare PCM is in, interior lights still turn on with doors, locks work, everything works when key is forward. Thats a good sign i hope.
Here goes nothin.

Reading PCM, it is from a 97 ultra. Hopefully it will open in DHP!

If i change the VIN to my cars VIN, does the OSID change too? The OSID for this PCM is the one listed as supported for DHP, i hope theyre right.

Edited a few things and flashed back to the PCM, everything went smooth. Car wouldnt even crank but there were a few security codes, i am currently on the second cycle of the security relearn, hopefully it at least cranks if not runs after...

Still wouldnt start after security relearn, so i got a hold of a 98 LS .bin and spent the rest of last night and a little this morning switching some fuel/spark tables to my spare PCMs bin file.
Im about to do one more write, if it doesnt work im going to have to put the stock PCM back in until later, i have work at 3 evil
Hopefully itll start with the stock PCM still lol...

You know how to export/import tables as XML files, right? Speeds things up.

No lol, havent looked into the actual tuning as much yet, i didnt even know if i was going to be able to tune. That probably wouldve been something good to know last night but oh well at least it runs now lol

Yeah, you're going to kick yourself now, but glad you figured it out!

Damn, then i wouldve went to my PCMs tune and just imported the same file that was exported? I saw the import/export last night but i knew nobody was around to answer questions so i did what i knew would work

Yeah, you just export the table as XML from the BIN you want to copy from, whatever table it is (Spark, MAFF, etc.). Remember where the file was saved. Open your new BIN and import. Select the file you saved and it's done.

This isn't only faster, it also keeps errors at 0%. You might want to go and redo anything you manually keyed before, export/import the tables and re-save, just in case you miss-typed anything.

Now it's time to firm up the shifts, raise shift points, and advance spark timing a couple degrees. Dump in some premium and tear up the roads!

BE CAREFUL! Adjust 1% or 1 unit each time if you don't know for sure.

Re: XML - I like to export as CSV, so I can open and freely edit and graph with Excel. This is especially helpful when working on your VE table - it's nice to put it in a 3D Excel graph and look for anomalies/spikes.

Really glad to hear you got it working! Glad my suggestions were helpful!!!

Good info; I forgot about CSV. I'm going to try using that next time.

I just realised something after i drove to work and the tranny seemed a bit funny, im not sure if the l36 park ave trans and the l67 park ave trans are different, but i think its safe to say they have different gears.
I hope i didnt mess anything up by driving like that. Back to more editing when it slows down here.

Found this link at 3800pro: http://www.3800pro.com/forum/pcms-tuning/33347-ducken-dhp.html

Scroll down and find this post:

"Go in and turn off the security stuff, that will prevent it from starting, or do a security learn. Once a new PCM is in a car, the BCM will revolt and not let the car start...."

I don't know it it's relevant to your situation or not, but just something to be aware of.

Oh yes, the NA motors had 3.29 gearing and the SC motors had 2.93 gearing. You'll want all the transmission tables from your old PCM.

Sorry I hadn't thought of that!!!

The only thing really out of whack is the shift points. You can drive it, but don't get on it until you bring everything back over.

By everything - off the top of my head I am thinking about pressure tables and gear ratio tables. There might be a spot with tire rotation as well. Hopefully all of this is inside the transmission pull-down and you can just export the whole thing.

Car is running/driving. The no crank was solved by security relearn, the no start was solved by compying the fuel/spark tables from a 98 LS. Now im having trans problems.

A quick search says park aves have 3.05:1 gears. IIRC gear ratio is found by multiplying first gear ratio by axle ratio.
Im assuming the axle ratio is "Drive_Sproket_Ratio" in dhp?
If so, does this look right for the ratios?
First gear: 3.05
Second gear: 1.56
Third gear: 1
Fourth gear: 0.7
Reverse gear: 2.38
Drive sprocket: 1

(3.05x1=3.05:1) right??

Anyone?
Also, should the tranny be making a bit more noise with higher pressures/etc.?
