for those who may have been wondering...
I just got my motor running with cos3 and with the a/c pressure sensor input for the ecm controlling the (1)efan and temp sensor on the other still works after converting to cos3.... also shifts at part throttle in 4low.

I will look soon and let ya know... But the Efan nor the 4low part was originally in the base tune. The engine segment was swapped onto a 4x4 trans segment tune and the efans were turned on via tuner cat and then copied with efilive to get that part working and then converted to cos3. Edit: Base tune OS # 12212156 Cos#. 02020003 |

A while back when the 4low shifting issue was going
On I misinterpreted the original ? The regular tune files and even cos3 will shift in 4 low BUT you have to floor it then let off.... Then it shifts... The converted file works like a normal shifting setup. I Originally was thinking guys tunes would not shift at all... But now it's clear what was going on. |

Yeah Iv had mine working with a 4l60e for a while now. I used a base tune I think s10mods put together. It was a ZR2 base tune with the e-van engine segment swapped into it. So what was used for the base tune with a 4x4 4l80e?

If you get the base tune file from him let me know I would like to do the 4l80e swap one day. Actually I think he has it posted on the efilive forum but I didnt know if anyone had tried it or not.

I was running that one modified for the 454 for about a year now. If you need it, I can send you
My old tune and just change the tables to fit your setup. |

Ben,
I can send you my current tune cos3 tune and you can copy your parameters over to it if you want.... But "I" personally didnt fix this issue... I believe it was S10mods that did it for me by swapping my engine segment over to a 4x4 4l80e tune file |
