[Axianator]

see thread for transmission not working information. I doni't think it is tune related.

Yikes! I certainly don't envy all the issues you've had with your transmission...

If you're using factory values for your transmission functions on a rebuilt unit, then I would agree that the factory programming would not have much (if anything) to do with your current situation. More than anything, it sounds like an internal mechanical issue that popped up as a result of your parts reassembly process, which may have been aggravated by the final drive change.

Speaking of which, I notice that you haven't mentioned whether your gear ratio scalar changes were successful...

I viewed my onld tunes and it seems as though i've been running with the torque table at 300 across the bord for a long time. that kind of sucks to hear.

If you've been running calibrations with an Engine Torque table whose cells all contain a value of 300, and you've been doing this for the past several months, then you have almost certainly caused internal damage to your tranny.

Not to high jack the thread at all. Just wondering where I could get the MAF calibration codes and files (or whatever I need to program it)for the FMS 76mm MAF.

Unfortunately, I do not have a transfer function on-file for that particuar MAF.

Unless someone here has a calibration flow sheet for this MAF, I would recommend that you pop over to the Yahoo! TwEECer mailing list and post a message requesting the transfer function values for this particular MAF. If you're lucky, someone will provide you with an approximate 30-point transfer function for that MAF that you can plug directly into CalEdit.

yes it worked... sort of. after I entered the values it changed them all slightly. i'll post what caledit changed all of the values to.

and you've been doing this for the past several months, then you have almost certainly caused internal damage to your tranny.

Well it did die. all clutched burned and sprag retainer melted (plastic)

I re wrote the gear ratio changes and the stayed this time. I drove it and noticed no change. my TC will still only lock for about 4 seconds then unlock harshly.

I tried changing the tranny torque table in intervals of 24 like you mentioned in your liked thread above with no noticable change. I only changed it +24 on one bank and +48 on another bank.

I got home and tried changing the TV values. I bumped the dynamic TV 1-2 and 2-3 by +10 to 45 on the last 4 boxes. the only noticable change is that it take about 4 seconds to shift into thrid under light throttle. So I returned that back to 35 where it was.

i'm still trying to find that agressive shift.

Necroposting quite a bit here, but this release is quite useful for those of us still using CalEdit for the ATX, and isn't mentioned anywhere else - SHONut or elsewhere. So I bumped it a bit.

This is a very useful file though if memory serves.

if you contact popsracing he has a file that has significant updates beyond this one.

 

[hawkeye18]

Can't afford it right now! I'll contact him when I'm ready to get back into tuning the SHO for real.

i am aware that you know but anyone who comes across a thread form 07 might benefit from the advancements we have had over time
