Help I bought two 1990 corvette proms for a stealth ram swap into a 72 chevelle figuring they would give me a starting point. They are part number 16134302 with ANHU 1613 on the proms themselves. But when I read them they are coming up as a $26 mask not the $8D?? I checked both of them to see if they showed the same and they do. I cannot seem to find anything about a $26 mask, anyone know anything about these.

Thanks for any info

 

Is this a Memcal or just an eprom? What are you using to read it? Maybe post a picture of the memcal and how you are reading it.

FYI, there is no such calibration as a $26 listed at Tunercat. Maybe you are reading it incorrectly, the eprom is bad or it was re-programmed with something else along the way.

If it is a GOOD memcal, you can always get the ANHU bin and reprogram the Memcal. BUT I would be more concerned that you have the proper $8D memcal in the first place as the memcal is critical for SD ECMs and needs the proper netres.

 

I just looked on Moates' Fileman, and couldn't find an ANHU bin there. I wanted to check to see if may the wrong byte is being looked at for the mask ID.

 

I am using a tectronics e-prom flasher to read it. I checked both chips and they both are showing the same thing. But the funny thing is that I have had one of them in the ecm and was able to scan it and get good data readings and the car would start and stall because of the theft system. I have read many other chips before I am pretty sure I am doing things correctly but I will double check myself tonight when I get home. I came up with the same dead end on the $26 mask so I must be doing something wrong. Will keep you guys posted on what I find.

I figured worse case I can get a different bin as suggested and use it. I joined moates site to try and get into the fileman but it won't let me in, do you have to be a member for a certain time to be allowed in there??

Thanks

 

Oh I forgot to add that when I try to open it in tuner cat it comes up saying need $26 def file.

 

You should be able to access fileman without being a member. Make sure the proper username and password is put in the fileman login pop-up. The site tells you what to put in.

 

I played with it again tonight and I figured out what I was doing wrong. I made an adapter that plugs into the prom that I can put into the pocket programmer socket. When I was putting it into the programmer I was pushing it down to far and must have been grounding out the pins inside the programmer. I lifted the adapter up some and then the chips read fine.

Made some changes on the chip burned it and plugged it into the chevelle and it fired right up. Now just need to put some seat time in it to work out the bugs.

Thanks six shooter for the info on moates fileman site.
