Silly me,

I just foud out my Howell chip is using an AA mask.

Looking at TunerPro using the Super_8Dmv1.ecu,
Constants
Chip Code Mask
AA

Comparing it to the AXCN bin, it's 8D.

What is this? Is it compatible, or is it time to start over with a AA mask?

I looked around for an AA mask to no avail.

It's in a 7730.

Should I simply change the mask on the new chips I burn to 8D?

Thanks.

 

Interesting. That isn't a mask id at all, it is the value used to bypass the checksum calculation (the $AA). I'd check the Howell bin for table locations and code fragments to see which mask was actually used.

Thanks for replying on a Sat.

Ummm... Sure. How do I check for fragments and which mask?

I think it would be easier, now and in the long run, if I simply were to take the AXCN and convert my Flags, Constants, and VEs to the AXCN, and make it my own... right?

I also changed the cylinder volume size to reflect my BBC(402). I had to do that with the Howell bin anyway.

Most everything is the same with the Howell and the AXCN bins. Even the injector flow-rates are the same!?!?!?

I simply converted the VEs to my calculation 108/128 x [AXCN VEs] and it's pretty close! I get ~ 128 - 134 BLMs.

As it was before, even when I first got the Howell BIN, the AEs and PEs were wrong anyway (pretty close to stock with some weird stuff numbers in the upper temps).
