Not on my end. I was all fired up to get started when I originally posted but I had to put my TBI conversion project on hold. Hopefully I can get back to it this summer.

Does the 7427 reset/"zero" the IAC when pin B is grounded, or is that just the earlier ECM's?

Since Mark shared this with me in another thread I thought I'd pass it on:

I'm 99% sure Toyota used a 4-pulse generator; I would check on Mud or Pirate before spending a lot of time on it.

I'm a fellow TBI noob and I've been trying to figure out "hardware" issues- including VSS for a transfer case- too.

That's an 8 pulse (8,000 pulses per mile) speedometer sender, probably for an...

This is for a '7427 PCM and I will probably omit the ALDL connector for a permanent install. So can I just de-pin the white/black wire that terminates at pin B from the PCM and pitch it?

What do you do with pin B on the ALDL connector?

Mark:

I don't even know if there's a hack for the OBDII PCMs, but could you possible extract the MAF flow/frequency table data?

I've found tables for just about every other MAF except for the...

I loaded BRDW into TunerPro and (using $0D definitions) ran a comparison with BJYL, focusing on the spark tables. Even to my uneducated eyes the results were surprising; main spark tables were...

That's exactly why I'm interested! So what is the BCC?

Any idea what bcc's they used?

What is the normal input from the VSSB to pin F13 on the '7427? Some sources say 2k PPM, but others say 4k PPM. And when do you need to set the "Output Speed not from DRAC" flag?

Thanks. Any idea on what types of vehicles GM used the low-profile horizontal TPS' that point to the side instead of up? Looking under the hood of every '85 to '93 GM vehicle in the yard will take...

Okay, I'm off to the wrecking yard this weekend to find a Weatherpack TPS that will fit my throttle body. What year did GM switch over from Weatherpack to Metri-Pack fittings on the TPS? Any...

I spent some more time with the $0D bins and the TunerPro Difference Tool and have added additional pages to the spreadsheet showing the tables values for BJFC (4.3 manual), BDXK (4.3 auto) and BJYL...

As a newb I can appreciate how confusing these different numbers can be; $5B is the mask which controls which parameter (xdf) file you need. The "bin" file a/k/a "broadcast code" or "BCC" is AXMU...

CdeeZ:

I sent a copy of the spreadsheets to Mark and I think he's going to post them, but if you want send me a PM with your email address and I will send them to you tomorrow.

I'm hoping that...

Okay, its official, I have too much time on my hands.... I started comparing several bins using the Difference Tool in TunerPro. One of the first things I noticed is that there is a lot of...

I've been using the Difference Tool in TunerProRT to compare bins, and notice a fair number of entries marked "Item Not Defined." For example, when I compare $0D bins BJFC and BDXK I get "Item Not...

Mark, hope all goes well.

I compared a $0D 4.3 auto bin to a $0D 4.3 manual and then did a separate listing of the differences between an $0E 7.4 auto and a $0E 7.4 auto. My next step is to compare a $OE 5.7 auto trans bin...

Just out of curiosity I used the Compare feature in TunerPro to compile a listing of the difference between manual and auto trans bins in $0D (4.3L) and $0E (7.4L). I excluded some of the minor...

Is there a way to copy and/or export the information compiled by the Difference Tool to an Excel spreadsheet?

Edit: I'm running TunerPro RT

Can you elaborate? If I'm reading your message right, you seem to be having second thoughts about your earlier recommendation that I start with a $0D/4.3/manual bin now that you've had a chance to...

Okay, in an effort to give something back, attached are three manual bin files compatable with the 16197427. I can take no credit for this information, particularly BJFC which Greg apparently...
