Would it be ok to import the arap maf tables to my 89 stock 350 bin.

 

I dont see why not, but that is accomplishing the same thing as just changing them, I would think. I have been looking, and have seen alot of different maf tables on stock bins. I have another arap question too. I ran arap.bin in my 87, and it wouldnt shift. When i compared the arap to my stock 87 (abwn) there was another flag enabled on mine. Does anyone know what the b2-b7 flags are in the vats and trans flags with winbin? I used the stock 89 AUJM i think, and same thing, so I enabled b2 & b7 like my 87 bin, and it shifts norm. Any help would be much appreciated.

I just got done importing the AUJN timing tables and WOT timing to an ARAP bin. Works absolutely great, Just fired up the scaner and drove around town with 5 knock counts from startup and not a single knock under running. Now its time to figure out how to lean it out at idle without touching MAF tables and Voltage vs injector tables

 

tpi-roc, I'd still like to get a copy of that bin, if possible. Would like to try it in my 87. TIA

I mailed it to everybody who requested it.

If I remember or see this post again when I get home I'll send one to ya.

 

The arap timing is way to advanced for my mild setup.It would'nt even start.I got it to start by putting the timing @400rpm to my stock bin.As grumpy says give the engine what it likes.My engine puked with the arap timing.The stock tables doo need changed but I'de rather have less spark.I like the tops of my pistons to stay attached.But thats my car with a stock cam.The maf effects alot in the code.I just wanted to know if my tuned spark table will be off.But I guess I'll try the arap maf tables.

I also tried the arap bin in my 87. WWWWAAAAYYY too much timing. I think its for the alum headed vette, which would explain all the timing. I think using a stock or similar timing curve imported into it would be the hot ticket. Like what tpi-roc has. I am using the stock 89 bin at the moment(AUJM). Seems to like that. Gonna go and scan the car in a few, to see whats up.

 

Yes...in fact, I have found this to work better some times. Just remember that there are some other settings that also need to be taken over. Don't forget to change the "MAF Table Scalar" to the maximum gms/sec for each individual MAF Scalar Table at addresses: C5B3, C5BE, C5C9, C5D4, C5DF, and C5EA.

These are values people seldom change when they dink around with their MAF tables and then wonder why it doesn't run right.

This is just one of the many "getchas" when you screw with MAF table entries. And why we don't advise doing it unless you have read the "hack" entirely and know EXACTLY what you are doing...which few do.

 

Grumpy has said not to touch/mod the maf tables period.Your statement indicates otherwise.Could you explain?






There is only one thing that I don't understand.If the vette has the same pn maf as an fbody then why is the table different?Better yet there is several different stock f-body bins w/ different maf tables,how?why?

 

Glenn, I don't understand these addresses... I've got a 16K bin, ie; 0-3FFF. Where do I get C5B3.

Is there a better way to use ARAP without the wild timing, maybe copy the spark over from AUJN?

 

I am wondering the same thing. Also, with injector sizing, and batt voltage, when I get my idle rich enough, everything else gets overly rich. Ive been trying to stay away from the maf tables, but don't see another alternative. I have been thinking of changing just the idle ranges of my tables some. Can always put them back if another idea comes up.

Oh, I think I figured out the answer to my own question... the 128K rom gets loaded in the C000-FFFF range. So the address in the bin file would be 5B3, etc.

 

Wow, I made those changes, and the car runs so much closer to 128 now. Thanks Glenn.

 

I did this.

 

And no one really seems to grasp how the code runs in so many parrarel ways.

If you sit down and really look at how things relate, every little damn bit of code ties to other things. Change the MAF and you changing timing, TCC, PE, IAC / throttle follower, all you AE stuff.

Then when you do esplain how to synch things up folks want to agrue over one element.

Like I've always said there is a huge difference from it's Right to it's CORRECT.

 

Given what you just said do you think the arap maf tables imported will have ill effects on lv8?
