Hello,

1990 corvette with ECU 1227727, has ANHT chip. I have the Moates APU1, and was inquiring about burning a chip with the AUJP as I wish to datalog wideband gauge and I've read this is what I need. Anything special I need to do, or just burn chip? I get a bin from a 350 and possibly same hearing 3.07:1.

 

Can’t help with that but If you want I could write a tunerpro patch to anht to read the wideband off pin f14(?).
anht is almost identical to axxd so it’d take 5 minutes to write the patch.

post up your xdf and bin if so.

 

Hello,

That would simplify things greatly, how ever, site would let me upload the .xdf file

I think c21 on the 727 is the same as f14 on the 730

 

save as .txt file to upload.

 

hello, here are the files, I also added the adx. Im also running the waterproof 1227727, and the equivalent to the F14 pin on this ecu is the C21.
my 90 corvette ANTH IS the .bin
$8D-1227727-1990Corvette is the .xdf
$8D-1227730-V1.1 is the adx

Let me know if anything else is required.

Thank you.

Marc

 

When you guys says C21 vs f14 are you saying the software reads the same address but the pin is different? I assume so as all the A/D read addresses are the same as the 7730 from what I remember.

 

Honestly I can not answer that, I've just read that pin c21 on 1227727 is the equivalent to f14 on 1227730.

 

I’m seeing this:
https://www.thirdgen.org/forums/atta...900d1185458709
which tells me the lookup for pin c21 will be identical. Makes sense because as I said, the code is nearly identical anht to axxd.

I got your stuff let’s see how motivated I am.

 

Exactly what i was told and found. Top 7730 with 2 connectors, bottom 7727 with 4 connectors.

 

****************DISCLAIMER I do not have a test car. That means you're the test car. Use this at your own risk, this is UNTESTED!*****************

This patch **SHOULD** read C21 Voltage input and save to 01C5 (raw) and 01C6 (filtered with Wideband Coef) and with the ADX will output a scaled datastream for an innovate LC2 wideband sensor. Any other wideband will need the scalar changed to suit.
the supplied XDF has a datalogging "scalar." "Input Logging pTPS_AD x09" The value here determines which value is in your datastream. OEM is TPS raw, so you'll lose that when datalogging, but the other TPS will still work. Change the value to any of the values mentioned here to datalog. You'll have to change the supplied ADX file to suit whatever you hook up!

This patch also **SHOULD** read A14 and save the V to 01C7 (Raw) and 01C8 (Filtered with Empty filter coef)

 

I completely understand me being the test car/guinea pig, and with the instructions i have found for wiring the innovate W/B i think i should be in a great position. thank you for you time, and i will let you know on how things worked out.
