I've tuned my IX using ecuflash. And one of my friends recently bought an VIII which was supposedly tuned before. However the car was running very lean so he asked me to look at his tune. After making adjustments to the fuel map I looked at the timing map and was shocked with what I saw. I have no idea if this is just some weird way to do timing or if it is just really bad. Looking for some advice if this tune should just be thrown out and started from scratch. Mods are, intake, tbe, walbro 250, 272 cams, stock turbo.

Sorry for dropbox link, photobucket was killing the image quality.

Thanks for the help.

 

What were you shocked about?

 

All the ignition advance in the idle region of the map.

Also I meant ignition not timing it was just a long day.

 

Timing and ignition are used interchangeably here.

Timing map doesn't look completely out of normal to me, I don't see why you'd start from scratch. Do your friend's car have big cams? Would explain the added timing at idle.

 

Possibly added timing (the corner of 24's) to catch a low idle situation...

 

It does have large cams. I was just wondering if that much added timing was normal.

 

I gotta say, having between 15-20 timing at idle does seem pretty damn aggressive!! As for the rest, no one can say if there's too much timing without comparing it to a log. Some cars do better with timing than others - plus the mods and supporting parts play a huge factor.

 

Id say that seems a little high at idle. What 272's are they? Something with a low lift like bc or hks wouldnt need nearly that much timing to idle smooth I'd assume. Im slightly confused on the load values...? 14 point jumps after 100 load all the way up to 380?? I could be wrong but I doubt a stock viii is getting anywhere near there. If it were me I'd rescale the load and work with getting rid of the blockyness of the map.
