anyone have a problem when doing a reflash of the PCM with the change engine oil light coming on? I have reflahsed my 99 and 01 and both after the flash change engine light came on.

the only time that has happened to me was during an OS upgrade. Reset the light and all was well.

Has been noted a few times now, strange, we are 'supposed' to be resetting them after a full flash....will look into it.

If anyone wants to do us a BIG favour, can they please send me a tun file after a flash with the light on and one with the light off after the reset.
I will double check what my bench PCM's do.

Cheers,
Ross

I've put quite a few miles on mine (2 oil changes and more than 20 flashes) and have yet to see the change oil light. Usually, I see it by 3500 miles or so when I haven't flashed the pcm (spirited driving plays a factor). It's now been close to 5000 miles and no light.

It will only occur after a full flash.

I had the same problem a couple of times.
