The LT1 That Could

Should I expect any shifting problems with a 3500 stall on a 95? I will be getting it tuned for the converter, but I have heard stories people had problems after tuning as well. bad tune?? or just a bitchy PCM??

I know BH can do it no problem a friend had shift issues with his 3K stall in a quick bolton Impala till he got an update for the TC from Bryan and all has been well since.

Ed Write Designed the only true fix for it

Ok so EW has a fix for it and I believe he had the fix before BH but that does not mean BH's method is not a "true fix". EW is the original LT1 tuning god, but people should not feel that by using BH or madz28 that they are getting less. I know a couple guys that had EW and BH each dyno tune their cars, each ended up with just a couple HP different, just for the cars to be that repeatable on fairly aggressive setups is impressive, call it a tie and both exellent tuners. BH costs less and will do mailorder and free updates, to me that is a tie breaker as far as whom to send my money to.

To the best of my knowledge Madz28 does not as of yet have a software fix for this he instead recommends swapping to OBD2, other than that I would not hesitate to use him.

Well 96 I do get tired of butting heads with you. SO I will concede just to get it over with.

YES The TRUE fix has been copied and can be had cheaper yes.

BTW "I" was the one that came up with the swap to OBD-II to fix the problem. I shared it freely with everyone. It works great and i still swap back and forth. I found the OBD-II system to have more finess then the OBD-I sytem IMHO. MADZ28 does good work.

I hope this helps some and I will make sure not to say another word around here about it.

Hey 96capricemgr what are the symptoms of these shift issues (or are you refering to the stuck in first gear after flashing the converter to high off the line?)? Can anyone who properly knows how to use LT1-Edit fix it if there are issues or is this a BH or EW secret (besides what TF4lv mentioned about OBd2) only

The OBD2 swap does work and any contribution like that to the community is appreciated. To me though why swap to a computer system that means paid updates ,more expensive looing and scanning and the tuning software costs 5 times as much. If it was the only way around the high stalll issue then sure but there are other options so why not use them. As far an Ion(madz28.com) doing good work, I will probably end up having him dyno tune my car at some point since he is closer to home than BH(Bryan Herter of pcmforless.com). Matt the shift thing is the issue, I just let Bryan deal with on my pcm, at this point I limit myself to small changes and drivability improvements, Tom might be of more help than I.

Yes, if you take it to either PCMforless or Madz28, they can tune your car for that size of converter...No prob..

BH is Bryan Herter- owner of pcmforless

Guys, don't get into arguments over who did what first. Ed Wright did my first tune back in 94 and he was good, but just like anything else, something can always be improved on. Since he was the only tuner at the time, $400 was a must pay deal. now-a-days, $75 for program w/ free updates and $95 for a cable.....I'll give you one guess who I'm going with, and Bryan hasn't failed me yet.

I had an ST3500 in my 94 and was OK until I stalled it up. if i left off idle all was fine.

I have a 93 T/A converted to mass air (OBDI) and have a 2800 vig stall. A few times at the track I have OVER stalled my car and it sucks ***! I will be converting to OBDII so I can use a higher stall.

With the right tuning you CAN use a high stall with OBD1 the OBD2 swap is unnecessary. If you have the stall issue with OBD1 get the right tuning and it will be fixed.

Explain to me what would be changed in the tune to correct this???

All I know is BH can do it and I have heard as was discussed earlier in this thread EW can fix it too. Ion has not figured out the fix yet so I am thinking this may be more than just tinkering with standard tables. These sorts of things are one of the big reasons I use a proffessional tuner(BH) for my tuning then I just tweak it to make it fit me and my car better. No tuner is going to get everyting spoton from several hundred miles away for a car and driver he has never seen, they can do pretty good work though and the tinkering I have found myself doing is usually minor, a degree or two of timing here a few mph change to lockup points, on the dyno my AFR was dead on perfect.
