TCC output blinking when I mess with certain thinks like Hiway cruise

[Dieselbird]

Wow, good to know that I'm not the only one with the weird AFR table. It must be pointing at the wrong area of memory. Yeah you've definitely been helpful! At first I thought I might be crazy since so many people use this XDF.

Got to test on the way home from work, Turns out I hadn't messed with the Min CTS but changing my hiway AFR table back to the bogus numbers fixed my TCC problem. I guess I will have to check out some other XDFs for what addresses they use for that table

I didn't see it ever go into open loop signifying the lean cruise mode. Weird, more digging to do.

Side note, I did find something else in this XDF, the TCC table notes are worded kind of weird. I was never able to change the values to accomplish what I wanted until earlier today I read a post on here that explained the way the tables work

I had run a crudely modified timing table based on the PROM that was in the truck (labled ASDU but not?) I was pretty happy with that. I did a lot of BLM tuning and I had got to the point where I was getting the power I wanted but the mileage was not super. I could get 16-17 going mostly 60. I have an 84 firebird that I put a little diesel engine in that I drive most of the time so I didn't care too much and used the truck a couple times a month when I needed to carry stuff in the bed or tow, otherwise I drive the car that gets 60mpg as much as I can to save money on fuel. My car was out of commission for a while recently when I was waiting to find enough time to replace the clutch cylinder so I found myself daily driving the truck and got interested in tuning again to get a bit more mileage out of it. I really need to get my EGR put together but that's another story.

This time around so far I'm running a stock L03 FBody timing table and a stock AJUK fuel table and my BLMs are pretty darn close and the performance is great. I'm trying to sort out all the extra features like the lean cruise, DFCO and also get my TCC settings dialed in so it's not so aggressive before I do the BLM fine tuning again. I use the excel spreadsheet I found on here but I added more stuff to it to make it fancier.

One thing about the compression bump and good exhaust is I had to pop out the TBI idle screw cap and open it up a tiny bit to get my IAC in the ideal position at idle in order to get it to idle smooth.
