idle fuel at 6.5-7 ms??!! with 1000cc primaries

I got my 20B running, and it was running fine for a while. But some how it wouldn't start, and keeps flooding. I'm seeing the fuel as being 6.5-7 ms during cranking/idle. I recalibrated the TPS, it seems to have helped during cranking. But after the car starts, it would barely idle since the vacuum seems to be low, so the car is choking with fuel at a pretty high load point a couple of bars before 0 vacuum..

Any ideas on how I can remedy this?

Thanks, Claudio!

I turned off all of the correction maps, and edited the main fuel map, and that was able to get the car running ok... The ECU is E11V2.

Still a lot of tuning left to do...

Another question have is the zeroing of the timing. Before I had read the Hitman's guide on doing this. I turned the factory CAS alignment one tooth, and that seem to have made the timing mark sign up.

However, after reading the Hitman's site, I understand that I'm suppose to use the software to do this. So I went through the Hitmans instructions, and timing seems to be lined up. However, the tooth in the CAS is still off by one. And the timing on the engine monitor panel shows "336 degrees BTDC".

I guess I should re-align the CAS and re-zero the timing?

lol, we ran into this with mine.... in my case the 3d coolant map kept turning itself on

the tooth offset # is also the amount of timing advance you can run, it needs to see the home tooth before it can fire the spark. the dumb thing is it will let you set the map to whatever you want.

mazda's system does a maximum of 48 degrees of advance.

AND you need to set the timing just flat across the board and make sure it stays all thru the rpm band
