Hello. Have a restored 69...

...Camaro w/ an LT1 that I’m a little skeptical about the programming of so here trying to learn and then verify and fix it.

Are you able to post the flash from the LT1 computer?

Here's the bin file. I only pulled it yesterday from the 1994 vintage ecm using EEHack and have not figured out what the best next step is to read what I have. I'd appreciate input on what would be good if the bin file isn't ideal to read etc.

Thanks

Have you seen the gearhead-efi $EE information available on this tread? http://www.gearhead-efi.com/Fuel-Inj...rmation-EE-EEB

In post 10 is the TunerPro .xdl file so you can see the information in the .bin file you posted.

YouTube has some helpful, but sometimes confusing, TunerPro video's that might help.

TunerPro download is available here: https://www.tunerpro.net/downloadApp.htm

welcome, nice to have another LT1 around

best way to see what's been done is compare that bin with the original calibration in tunerpro using the bin compare tool with a good definition so you can tell what's been changed...

i'll do it but also walk you through how to do it yourself

- download tunerpro (best bin editor), don't need tunerpro RT
- download EEX xdf (see my signature, best tunerpro definition...biased opinion for sure but nobody here will argue with you)
- open tunerpro and load XDF and your downloaded BIN
- in the parameter tree select 'view by: parameter category' so the eex xdf is easier to read
- browse through some stuff in your bin to get used to tunerpro a bit

now to compare.

- find a factory bin based on calibration ID assuming it's up to date with the base bin used (i checked. it's 16207211)
- download factory bin from my site http://fbodytech.com/bin-files-2/bin-files/ (the actual bin is http://fbodytech.com/bin/EE_16207211.bin)

we can see here your bin here is for a b-body car, so.. iron headed engine?? automatic? or....

- load the factory bin into tunerpro's 'compare' menu
- use tunerpro's tools -> difference tool
- ignore everything below 0x2000 and between 0x10000 and 0x12000 (no need to do anything just dont pay attention to those values)

okay so the first thing i notice is this doesn't look like your b-body bin. too much different, transmission..fan.. o2 sensors... so who knows whats been flashed to it. the calibration ID is obviously not what matches your bin. it's just too different.

thing is the calibration ID isn't stored in the bin itself it's in the EEPROM (which is USUALLY set by any sane tuner but it's not a guarantee) in your case i'd say cal id you dumped from eeprom when you read the bin is incorrect

lets download this and compare with yours instead...

http://fbodytech.com/bin/EE_16209461.bin

that's better. some diagnostic codes common to a swap have been disabled, a/c stuff, skip shift has been disabled, etc. but the bin roughly matches. a bunch of timing advance has been modified, stuff like that

actually looks like a fairly professional tune. nothing really stands out too much

anyway poke around and if you have any questions about specific stuff let us know

Will check it out. Thank you.
