can anyone tell me what they are supposed to be set at? I am getting random knock counts, nothing higher than 01, and I am trying to track it down. it doesn't occur at any particular rpm or psi. I bought the utec used and I just want to make sure that the settings weren't changed. I have a vf39 with sti pinks at 18 psi, a/f no higher than 10.5.

when in doubt, reflash the eeprom using the flash program available from txs.

you might want to save your settings if you have a custom map. if not, just use st. 4 parameters AND the st. 4 map.

how are you reading your afrs?

I have a wideband. I made a few more wot runs today and It seems like most of the knock I was getting was after shift. ecu was running mega advanced timing immediately after shifting. I entered some nice low timing values in the 0% column and all seems to be well.
