$8c 1995 4.3 cpi?

[EagleMark]

Have you tried using the $0D adx? That is what it comes back as for that truck.

I have that bin and looked at it in $0D and looked like it would work until I got to the fuel tables?

I also have an $8C and $8CB XDF, neither of which work for that bin. No hack found for $8C...

The $OD.ADX might not be correct, see attached .xdl's. The spark advance is WEIRD!

There's a lot more wierd then spark advance... I can't find any other ADX for it, or an accurate $8C to read the bin, lots look good with $0D till you get to tables.

Since it's a 16197427 how about a $0D bin to start?

It hurts me to write this ... TunerCats offers $8C. Maybe I need to use DataMaster TTS for this Tune? I think $8C might have some parameters for the electronic transfer case? Not sure if $OD would good option just yet.

if tunercat does have the correct 8C(and it wouldn't be the first time they've mislabeled an odd calibration), then it could be converted to a tunerpro XDF....

just saying.

EDIT: ask tunercat to send your BIN their way and have them verify that the XDF is correct for it.

TunerCat does have an $8C and $8CA for those trucks.

But I have an $8C but it came in a folder marked "8C 1227748 90 2.5TBI L68" and $8CB that don't work...

EDIT: From the ADX/XDF Lookup "16245358 27C512 $8C 95 C & K Truck, Van, 4.3L $8C.xdf Maybe OBDII ? A309.ds or A217.ds ?

So what PCM is it?
