TBI Maf Help
 

Hi everybody, I know this has been talked about, and I've probably missed something simple, still new to all of this. I feel like I've been reading dimented24x7 posts till my head hurts, so sorry for the long post.

I Had the 8062 4.3 , did a v8 swap in my s10 awd with the 7747, upgraded the 747 to the 27sf512 chip, then repinned my harness, got the g1 adapter, and upgraded to the $0D 427 ecm. I love this ecm, and have been reading meticulously on converting to maf. To be honest I'm stuck. So here's my story..
I started the the BJYL, and by using Fast's 700r4 xdf and EagleMark's tutorial on blms over on another website, got my VE table where it's been better than ever before.

I got the 5.3 maf, and have it all wired up. I have the signal for the IAT sensor, but not for the MAF. I loaded up the 0DMaf and made the changes to by bin, but never got a signal. On top of trying to do it with my bin the maf.xdf I have is a constant checksum error with aldldroid and will not connect with computer even with checksum disabled. Unplugging maf has no effect, So I'm assuming it just running on stock ve tables I put in.

So I did something probably pretty stupid, I had found a maf-experiment bin, and transferred a lot of settings from my bin over to it assuming it had the code in it, and viola, it worked, got a maf signal, and a horribly rich stumbling, fell on its face died. I Think maf signal went straight to like 5000hz or something. the maf.xdf does connect and read with this particular bin.

Yes, I did change the frequency table to the stock 5.3 one, and added 5gm's to lowest cell. I changed the INJ Flowrates for my inj to 7.7.

my questions were, why didn't my bin work? And/or how do I import the maf code to mine to execute?
Can someone help me with a somewhat generic 5.7 700r4 bin for an auto set up for maf I can make changes to?

My truck is a 1991 chevy s10 5.7 TBI Awd 700r4 mostly stock 3.73 gear ratio, (just changed to dual 2.5 exhaust, H02, and thats about it)

Sorry for the newbie questions, I had read for what seemed forever but you know if you stare at something long enough you'll space some things out...ha
So thank you in advance.

You might want to try posting on gearhead-efi.com. I know Fast355 regularly posts on there and ran the MAF setup for some time on his van many years ago. I have not seen dimented24x7 post here in some time.

Thanks for replying, I have talked to fast, and his recommendation was to talk to dimented, because he lost a lot of info on his hard drives about 5 years ago unfortunately. I checked Dimented's last login been a couple years. haha.
