The problem I am having is when I have TOG adjusted to where it's proper on the high load stuff, and IOT adjusted to where the car will idle nicely at 14.7 and 30-40kpa, as soon as it gets into the 50kpa and up zones it wants like -15 or more and creates a big transition. Trying to smooth that out by tweaking TOG and IOT but haven't found a solution. Any ideas?

Thanks

Post subject:	TOG/IOT question
When setting TOG/IOT, I know the goal is to get the raw fuel curve as close to ideal as possible. When adjusting the VE table, what would be considered an excessive amount? If I can get the high load stuff close with TOG but have to pull 15-20% out of the low load, is that too much? Thanks Shane

Nope.

There is nothing wrong with having an adjustment such as that. Does the car not repsond to the adjustment or do you just think it is wrong?

I just wasn't sure how much deviation I should see. In the manual they stress the importance of trying to minimise the amount of correction necessary through IOT/TOG but don't give any frame of reference (+/-10, +/-30?) After talking with Uve I am feeling comfy with the numbers I am getting now. Thanks! Shane

Take a look at the table, it probably has a change in A/F at the same cell as the VE changes. I graph my VE normalized to one A/F for analysis purposes. The curve from the normalized computed PW values are smooth lines where the raw VE is not. By this method I can change the A/F table and overlay the old data on the new and make a new VE table from the new normalized curve. Done it many times.
