How about another funny issue i've personally noticed..
This is also a different table: A0014
Its the IAT multiplier. It says to put anything above 1.00 to multiply the VE table upwards, but I've found that in colder temps, I have to put something BELOW 1.00 to increase fueling, and anything above 1.00 to REDUCE fueling (hotter IAT's). Has there been a fix for that? I'm running COSv5 OS# 02020005.
Thanks,
Adrian
Hi Adrian,

Thanks, still not sure why its backwards? It must just be the way things are calculated.
It may not necessarily be backwards since the A0014 table is only as good as the data it recieves. Any variation between reported temp fron the iat sensor and actual air temp can have the table heading in the wrong direction once adjustments have been made.
Or like you say it could be ass about in the software.
The Tremor at AIR
Well usually you're wanting to add more fuel when your IAT is lower than what your IAT's were when you set your VE table. For instance if you tuned at 70F IAT and have all your VE table values set at that temp, the IAT multiplier is to help you compensate for the difference in colder/hotter weather. So, with colder air, 30F IAT's you would want to ADD fuel, hence a value above 1.00, but in reality you have to input a value below 1.00 which according to the description of the table would be taking away fuel, leaning out. But it actually adds fuel.
Sorry I haven't logged anything guys, work has had me all over the country the last two weeks, and given the state of things, it would not be wise for me to turn them down. Hopefully this weekend I'll find myself in town and with time.

Brandon, take your time, no worries, we've all been busy too.
Not sure why it would add fuel.
The value is a direct multiplication of the VE table numbers.
Lets assume your VE number is 1.000.
If your IAT table value was 1.010 then 1.000 x 1.010 = 1.010
If your IAT table value was 0.950 then 1.000 x 0.950 = 0.950
So given that the VE numbers end up lower I'm not sure how it could cause a rich condition.

Ross
