By changing this setting in TP and then uploading you have changed the mask ID in both then. I'm not sure how you would change the mask ID in the AutoProm without changing it in TP first.Quote:

Six_Shooter - Well the last time I tried it, I loaded the bin to the AutoProm, then turned on emulation, then remembered to change the mask. That didn't work. I will try changing the mask first then load, then emulate.
Oh yea, no driving today, gotta replace the brake master cylinder. :doh: :mad1:
OK. got it down the road to get gas. I was able to Emulate by changing the mask id first. Funny, I never read before that you had to do that. Anyways, I got the thing to idle down, iac sits at 14 steps. Put it in gear, iac opens up to like 45 steps or so, but if you put it back into park, it only closes to like 21 or 24 steps so idle is a little high. If I restart it does it all again. I can upload a datalog if that would help. Any ideas?
I am using the following.bin, def, adx.
I've looked at the .bin file that was downloaded. I think maybe to much advance in the near idle table. The reason I say this is because I just finished tuning a 383 with 9.8:1 / Single 670 CFM TBI. I also did a '427 PCM upgrade and used the $OE. The 383 is actually running best with a stock $OD BDWL timing tables and 92 Octane fuel. No knock sensor, with this 383 so I kept timing on the safe side. I also set the initial spark advance, and main spark bias to zero.Quote:

Thank you dave, I will give that a try.
You also asked earlier and I did not notice an answer. But yes you have to upload bin to autoprom when you change it in TunerPro. Also when you make a change to bin you need to save it, I think the command is commit! Then it is loaded to AutoProm.
You only need to use the "commit" function if you are using the hex editor to make the mask ID change. Editing the mask ID using the XDF, you just need to save the bin. You can save the single change by using the "save" button in the XDF editor box, then save the bin, as well.Quote:

Thanks guys. It's all working now. I got the speedo pulses figured out, now both the datastream and my speeedometer match. I got the LM-1 configured and the datastream is showing within 0.2:1 of the controller, I am sure that difference is just a ground offset, close enough for me though. Only thing I can't get to work right is the PCM control of the radiator fan. I have it wired up, the code written in the .bin, but no joy. I would like to put that bit in the datastream and add it to my TP dash so I can see if the PCM is actually turning on the output. I just haven't taken the time figure it out. I still need to go though my datalog, and make some adjustments to the VE but I am getting ready for work now, so that about does it for this week. Here is the datalog from this morning. Have a look and feel free to make some suggestions, Thanks again.

You followed all of the additions and changes needed for your specific code in this thread? viewtopic.php?f=9&t=153
Just to point out that, there is a couple hex characters that need to be changed to enable the code to work. This over writes a couple characters that are already present in the bin.
Yep, I changed the the entries at address 7C07 from D567 to 7120. That inserts the beginning of the fan control routine into the runnning code right?
OK guys, somehow I go the idle issue fixed, it goes into gear, and back to park, and idles right back to normal. New problem. I was not getting any PE but I got PE to come in like it is supposed to and sometimes it runs WOT great. However it doesn't run great all the time. In the attached datalog @ 2:15 and 4:25 you can see I start to go WOT, and everything looks good, TPS, MAP, SA, BPW, injector DC, it just goes lean and drops RPM. I immediately let off and get back on and it goes like snot, WBO2 is slightly rich, but good enough for now. I don't know where to go next.
UPDATE: I moved the external regulator closer to the TBs, the lean spike before the rich spike must have been a split second pressure drop between the throttle bodies and the regulator. I got the 1>2 shift sorted out, and I think the 2>3. The trans needs a shift kit/plate mod and the PCM needs the shift param's tweeked. I am going to take the injectors out and have them cleaned and flowed so I know for sure. AE still needs some work, but WOT is much better @ 12.5-13.2 AFR.
