TunerCat shift point problems

What are the proper tables in which you change your shift points at?

I logged my runs last night with Datamaster and it is showing shift points of 6375 roughly. I'm trying to get the car to shift at 6000 but it keeps banging the rev limiter and will not shift at 6k on the 1-2 or 2-3 shift.

Do I have the dreaded high stall shift problem that is common in OBD1 cars and if so does anyone have the fix other than Brian Herter?

Anyone out there have 6k shift points that they can send me?

Also, i've noticed that TC changes shift points based on MPH, is there a way to changed them using RPM instead? I have the 1-2 shift set at 40mph right now and it seems ok after tweaking but the 2-3 shift I have set at 75 yet Datamaster shows it shifting at 84.


Help.

for WOT shifts, tables are kickdown up/down shifts, and kickdown shift rpm. Hot mode tables are for when the car is running real hot. generally just use the values from the normal kickdown tables.

key is to set the shift rpm about 300-400 rpm lower than what you want to shift at and also set your shift rpm to about 10 mph lower than what you want to shift at, take a data master run and adjust from there. shift time which includes clutch/tc time and actual shift time works into the equation which makes the shift happen at a later mph than what its actually set to. What i did was set the shift rpm to 1500 for all 3 values. then just adjusted the up/down shift tables to the mph i wanted. works like a charm. of course you still have to fine tune the mph like i said above.

sent your fixed bin file back.

you can still raise the rev lmiter to what ever you want and to change the wot shift points use the kickdown rpm threshold table. to explain: for the car to shift it has to meet two paramiters one is the mph (dont change it) THE OTHER IS A RPM if you want the car to shift later, up the rpm, and to shift sooner lower the rpm, using the table i metioned above. but sence your using your rpm table to shift if you set the rmp table higher than the rev limiter it wont shift.youl just bang the rev limiter. so just be sure the table is set lower than your rev limiter.


glad it worked for you.

you can see part of the fix in some of the tables but you can see all it. so if you try and put it on someone elses car it will not work, and the reason im telling you this is to keep from possibly messing someone elses tranny up.

the reason i cant share the fix is becuse i told the person that gave it to me i would not tell anyone.

by the way i noticed your car is still programmed in pe mode to run in the neighborhood of 12.3 to 1. thats kinda rich for a NA car.

Not even sure what PE mode is yet, just started tinkering with this. I believe the car does run rich but I won't mess with that until I get it on the dyno with wide-band.

Thanks again for the help
