Highway enable not activating

**sciroc** · 07-06-2014

I have enabled the hiway patch and it shows it is enabled but it is not going into OL, which to my understanding it should when all the qualifiers are met and it goes into hiway mode. Is that not correct?

I just looked at the highway lean cruise code, it is supposed to be in closed loop.

Can you post up a link to the write-up you found that information? I was under the impression that it would go into OL during the highway mode due to the AFR moving toward the 16:1 area and if it remained in CL the ecm would constantly adjust to get back to 14.7:1 thereby working against itself.

This is where I seen the reference to it running in OL during Hiway lean. EagleMark made the reference.

This is my latest datalog and bin file. The hiway lean isn't engaging and I do not see why...all parameters are being met and the patch is showing up as installed

I'll try to take a look at your data log later tonight.

But it does go Open Loop when it enters Hyway Lean Cruise. Sure hope your tune is in order before you enabled it!

Post your bin file too!
