Interesting, at a glance the file looks fine but someone has been in it and didn't fix the checksum or the file is corrupt. I don't have a clean read of that .bin to compare, sorry.

Here is that...

Thanks for the files. hehe, you wouldn't believe the hodgepaws of adapters I have had to fudge together over the years. Good job :)

Rapid CEL is generally a bad checksum.
If you want to post your .bin file I, or someone, will check it for you.

The checksum(70BB) is correct so that file should be fine. Looks like a good read.

If these files aren't already in the archives, please read both memcal's and post the .bin files :)

Yes yes yes, thank you all for this great site :)

Thanks Shannen,
It turns out when I updated my email, it turned off my automatic messages and discount codes. That should be working again very soon so I will post when the discount codes start...

The '6395 and '7427 both have red and blue connectors. I haven't seen any physical differences myself. Maybe some others can comment if I am wrong.

^^^^^^^ very nice. the 7427 is an incredible increase in TBI technology, do not fear it :)

There are PWM EGR valves and solenoid controlled EGR valves. You could hook up a LED to that pin to verify and it seems there should just be a bit setting to tell it whether it is discrete or PWM. ...

I have no personal experience but seem to read those gauge thingys with external 0-5v do work well. Like you just asked, seems buying one and then re-sell when finished and pay forward kinda. Use...

Ok, one more edit :laugh:

Here's a link to summit for one of the widebands I use. https://www.summitracing.com/parts/avm-30-0310 It is Bosch 4.9 sensor(very good) and has a nice 0-5v linear...

I did not double click, has happened twice now. Doesn't bother me, just noting for the admins.

Yep, can't edit, new server has big issues :(

Here's a link to summit for one of the widebands I use. It is Bosch 4.9 sensor(very good) and has a nice 0-5v linear output. Like you I don't use a slow ass gauge but rely on my data acquisition. ...

The '7747 is pretty archaic and I don't think there is a prime pulse, from memory. If your injector/cu in constant is correct(very critical)...then all you should have to tailor is IAC counts during...

Hiya,
If you are talking about the in tank pump, replace with '96 vortec pump, drop in replacement capable of more than 60 psi(the regulator controls this anyway regardless of pump, unless pump...

I have a broken one of jets, definitely different firmware and doesn't appear to be any avt variant.

Google drive does not like my winXP lappy, post the 4k 2732 file here, I would like to figure out the checksum. It's not your issue but I am curious.

Something I found on the net about your other programmer. https://www.eevblog.com/forum/repair/how-to-program-eprom-m2732-21v-with-tl866/

I show 2732 to be 25v programming and 2732a to be 21v...

I can imagine the frustration you feel, it's like de javu of stuff we lived with in the mid 80's while we were learning :(

If you don't mind, post your 2732(x) .bin file and I will burn to stuff I...

Hiya Folks,
Just an FYI, I usually get updates to my discount fairly often and update here. Weirdness, I just got an email telling me my discount code will expire on the 26th(which I knew when I...

Welcome to freeware

The most common thing I have seen over the years is the EGR is still active in the bin file and there is no actual EGR.
