I downloaded BLM Locker, but haven't managed to get it to work. I keep getting a "file size is too small" error, and it won't let me do anything.

All my files are tunercat 32kB .bin files.

Anyone have any idea??

 

Well, unless the blocker is for 94+ Cars I dunno.

Where did you get the blocker anyway and I'll try it.

 

It shouldn't be for just 94+, I saw a couple of posts about it and it said any Tunercat or LT1Edit file.

http://carprogrammer.com/WOT_BLM_Locker/ is where I got it. I do believe that's the original writers website too.

 

All my files are 128kb and have always been that size... maybe SD is different.

 

That could very well be the problem.

 

I've never gotten it to work on a DA3 car.

 

Says its for GM 16188051 which is 94/95 LT1 (flash). The 128k rom size an earlier poster confirms that. I'll take a peek and maybe can make a patch for you. I'm sure all this patch does is force load the RAM byte for BLM to 128. Assuming you know which RAM byte it is.. thats no big deal.

 

Fastbird93, please test this rom:

I think I isolated the BLM stuff and locked it. That is an otherwise STOCK rom from my automatic 1993 Z28 (I did change the PROM ID to 6969), so please change / import whatever you need to make it run properly with your TunerCat.

I would test it, but I have my intake manifold off and tranny out

If it works, lemme know.. I'll write a lil patcher for it like that guy did.

If it doesnt work, back to the drawing board! Gotta show the 93's some love, I don't like MAF's anyway.

 

I looked around to see what you did, and couldn't find it. Care to share???

I've got to drill my BBK tb for a bleed hole today or tomorrow, and then run the car with the tune that's in it first, to see if that corrects the split BLM issue. If it does then I'll be playing with the tune, but if it doesn't it's going to be back to the drawing board. I just don't want to start messing with things until I KNOW what the cause of my 100% split BLM issue is.

 

I hear ya, ... the whole BLM locking is pretty band-aid from what I've been seeing. Basically I dasm'd a 94-95 ROM after applying the blocker (it only made 2 changes) and found similar code within the DA ROM.

Still a little confused as to how that works on the EE stuff, but I'll figure it out... anyway thats how he did it.
