Gents, If you drive, deaccelerate and you notice your trace block goes to the last column there is something wrong. And overflow condition exist during table lookup. This can cause lean/rich conditions. It's not good in anyway. Problem: Map value 90mbar Column0=110mbar What happens the lookup routine will search till no where to find a value 90 or smaller and read the fuel/ign value from there. It's not my code it's stock honda code. I show reading from last column but it's really reading anywhere. Solution: Lower column0 mbar to 75 or 80mbar. i'll post some datalogging screenshots later This are just number out of my ass.

This is a perfect example of what you see when it jumps in decel. It always happened to me in the one spot; so I just ignored the erroneous log readings and sifted around them. Image

Same here, first thing I noticed the first time I was datalogging. I thought it would be my Nokia datalog cable or something :wink:

Calvin, Lowering the first collum value to 85 has worked for me also. The latest version cought the error even after I lowered it to 90 85 seems to be working good. Thanks .

I have a problem when changing the mbar value in collumn 1. collum 1 was stock set to 127 mbar when i created the basemap, i click on 127 to get it changed lowered it to 85 but when i hit the enter button ectune automaticly changes the mbar value in collumn 1 to 11,31 and changes collum 1 to B1. I tested it with other value's 60 up to 120 but always get the same results. I run version 0.0.2.1 r9 vacuum in mbar and get the error msg when deaccelerate.Hope you got enough info Thanks

We have reported that bug to Calvin. The only way around it is to hex edit the rom, or enter -70 for now. Fix is coming.

Is the fix ready yet? I get the message every time I decel from high rpm, and all logging stops until I hit 'OK'.

I was referring to a fix for this. I can't lower column 1, it just replaces it with 11.31
