OBD1 High Stall Problem

What table(s) in Tunercat do we have to change to fix the high stall problem in OBD1?

ive fix several of them but you need to be sure its the stall and not tranny slipage or something.

waht size stall do you have?

None yet. Want to do my homework before I buy one so I'll know what to change in tunercat w/ it. :) Would be awsome if i could find some information on what table(s) relate to this.

sorry been gone this weekend.

im sorry i cant share what tables it is. theres one in the constants tables and some and the main tranny tables. if you get a stall i will help you if send the bin file to me. but i cant tell you what the table are because i told the person that told me i wounldnt tell his his secrets.

just a heads up, some people say that some times the fix dont work. but ive had 4400 stalls do great for a daily and preform great at the track. never not been able to fix one from tuning.

I am having the high stall problem. I just need a tunercat.

Would you charge for this? I'm thinking of getting a convertor but am not looking into higher stalls 'cos of this problem, although my cam likes higher RPMs. This would help out immensely. I've asked about the fix but nobody's willing to say, you're the first person who's actually said you'd be willing to help, I respect you for that bro! :bow:

no i will not charge, but if you go and by a 3600 stall. theres no garuntee i can fix. but im willing to help and try.

ive fixed 9 or 10 of them for people on this board, and have never charged and never will. im here to give all the help and info i can give, and in exchange ill take all i can get from the other people on the board.

Good man!

I seem to remember some information posted in this forum in the past...or maybe my memory is failing. :)

Actually there alot of ifo I found out while searching this issue. First thing I learned is this seems to be a huge big secret for some reason. I have the fix but never had the chance to use it before taking the motor out in preperation for a 383 so I dont know for sure if it wouldve worked for me. My only question after looking at the tables etc is does the fix has it's cons? Does it slow you down etc?

First off I would like to thank 97z-M6, for his response in willing to help fellow members, there are not too many out there like that. Second, I am thinking of doing a m6-A4 conversion, and will be running an Edge 3800 stall. I am trying to do a little research on this high stall problem, or sometimes referred to as "Stall wall". Is there a for sure fix for this? I am running OBD 1 as well. Also I didnt mean to hi-jack this thread. The question I have asked also pertains to the information trying to be seeked by the thread starter. Thank You!

From the research I did with the search and from everything Ive read everyone will tell you to get it done by pcm4less, Ion, or Fast chips. No one will openly say what exactly it is.

I found some stuff out. I'm going to post it when i have some time later this afternoon :)

Hey, i'd like to do a M6 swap in the near future, so if you wanna swap tranny's i'd be down, i've had a recent rebuild and currently have a 3200 stall. Just a thought, if you havent already bought an automatic.

i know some people change to obdII to fix the problem, how hard is it to change to OBDII? Do you have to change the whole wiring harness or could you hook up your PCM plugs to the OBDII pcm and just get a tune with the crank sensor and rear O2's removed? I think that's the only 2 main differences between OBDI and OBDII.

there is a garentee fix by ed wright, but remember if ed tunes your car, you cant scan it nor can you change programming. so your stuck

i did get the fix from one of the above names, but it wouldnt work on the 4400 stall, i had to change 2 other tables. in order to make it work. and it has not failed me since. and none of the persons mentioned above will garentee the fix but ed.

it took about 12 hours to figure out the fix for the 4400 stall, and it was acctually a better driver than the 2800 stall he had before, but the drive quality took alot of torqe covertor tuning.


Honda Hunter i have never heard any bad issues from this, and ive heard back from all but one person i helped.

Hey 97Z-M6, i've got bryan at pcmforless changing my tune for my 3200 stall, do you mind if i send you the file and let you look it over to see if you can further perfect it?

yeah send it on. vincentbergeron@yahoo.com


load it first and see if it works. you might not need to send it. but ill look at it.

send it on

ok, i sent you the .bin file. I cant load the tune till i put my cam in cause the tune is for a Lt4 hotcam plus he threw the stall fix in there too. I could have got him to make another one with just the stall fix and no cam, but i didnt wanna make him go through all that.

Why cant you scan or change the programing? Is it really possible to stop someone from doing it??

he locks your file..I think you can still scan it, but not download the file or alter it..

That's BS. No fix is worth that much. Now I want one of his files so I can unlock it and feel better.

lol ... yeah, the professional/shop versions of most of the Edit sofware let you lock the tune ... interlectual rights yo! pretty gay but how would you feel if you spent countless hours fine tuning and fixing shyt and someone just coppied it and made mad dough with it? This is why I preffer to learn to tune my own car so I save a bunch of money and get the satisfaction of saying I did EVERYTHING!

I guess I understand. Still pisses me off though. Hey Im from Gaithersburg as well.

well i spoke to Bryan Herter over at PCMFORLESS this morning, and he said he has a for sure gaurantee fix for this problem. He states "the VSS signal goes crazy because the tail shaft flexes, and sends the computer into limp mode." But he has the fix.

yeah bryan did the fix for me, i cant load the tune in yet and prove it worked. He told me the same thing, the tailshaft flex on a hard launch sends the computer into limp mode or something and it just shifts into 3rd and stays there to you get off the gas for a few seconds. He said some cars actually got stuck in 3rd gear till you cut the car off tho. My car took off, then would bogg and rev up but go pretty slow, cause it stuck in 3rd gear and wouldnt drop down till i let of the gas for like 3-5 seconds.

95whiteta, I sent you a pm, waiting for your reply..

There is no trick to fixing it. On a hard launch, the vss loses signal and the computer goes into "limp" mode.
You need to make it so that the pcm doesn't use the vss for it's wot shift calculation.

...wow, this is the first time I've posted in here in a while. :)

looks like it should work. but for a stall thats above 4000 i would change one more table but it should work for you
