perload switch A9L2 ?

Unread post by canuck1 »

I've been away from this for a while and can't remember if I'm using the correct perload switch setting in A9L2 (see image):

the parameter comments say

"PRLDSW - used for determining the value of load%.

Set for load% = load
Clear for load % = load/peak load
"

Does 'set for load% = load" mean check the box beside the word 'Set', then hit 'save'?
I know this is a question I've read here before, but searching doesn't yield the results to my question.

I checked all my old tunes and it appears I've never checked the box. I don't remember why I left it that way and can't find any answers searching!?

Thanks for helping me confirm I've got it set correctly.

set means checked
not set means cleared

its idiotic to set it as you will loose significant fuel control

You definitely need to read the fuel write up on the homepage.

Thanks. I have read the fuel write up (last couple of years) but don’t retain it well enough by the time I get back to work on the car. I’ll review it again. Thanks for the reminder about where to find the info.
