This sounds like a baller tool, but how would crome tune my car if it doesnt read a wideband. im pretty sure a wideband doesnt hook up to my engine harness, so how would it read and tune?
Any knowledge is appreciated.

 

It can't autotune unless you have a wideband hooked up. What do you mean the wideband doesn't "hook up" to you harness? It's not like a plug and play, you have to splice and wire it into your harness. BTW the autotune is not really that baller, it's not going to be anywhere as good as a properly tuned map.

 

crome uses the target AFR map to make changes as it sees fit. Sometimes it works great, sometimes it doesnt.....really depends on your luck i guess.

keep in mind when it doesn't work well, it adjusts the wrong way. So lean goes super lean.
I've had it work ok in the past, but IMO it's simply not reliable enough to trust.
As cool as it would be, there is nothing better than adjusting the maps manually.

 

It doesn't work well(my expierance) your better off setting a target AFR...
Logging you afr and select big range of cell that has somewhat the same AFR and adjust that.

You maps can look real nasty with auto-tune.

 

What is wrong with modifying target AFR tables?

 

The thing I've found autotune very useful for, is getting the part throttle maps smoothed out and driveable. I do the idle, drive around for a bit with autotune for part throttle, then go manual for fine tuning part and doing wot. I would definitely not trust it to do boost tables.
