Dies after idling for a few minutes

Ok, so after extensive experimentation and adjusting, I've gotten the car to start and idle using silverrotor's base maps. The only problem is, it'll start, idle but then die after a few minutes. If I try to start it again, it will start, but then it'll die within 30 seconds or so.

Which adjustments/screens should I be checking?

Keeping an eye on the wideband, it looks like it starts going lean as it dies. Fuel issue?

post start enrichment possibly keeping it running. When it times out, EMS uses base map. Base map to lean maybe? Just a guess.

Do you mean the water map? I just tried jumpering the fuel pump to make sure it wasn't shutting off for some reason..same results.

Was able to keep it idling by upping the fuel in the water map .. waaay up..at 82 degs, i've got it up to 41. s/b at 0, so something's definitely up. can someone poin t me in the right direction? Im assuming that if the water map sb 0 at 82 degs, there's another map that sb up that i should probably be adjusting.

Replaced the primaries with an old set of 720's. Works better now.

The main fuel map is lean. Once it is out of warmup enrichment there isn't enough fuel to keep the engine running.

I get that, problem is, as I implied when I said 'so after extensive experimentation and adjusting', I'm unfamiliar with this--which is why I then asked 'Do you mean the water map?'.

So I'll ask again--do you mean the water map? Is this the map I should be adjusting?

Which screen the 'main fuel map' that you are referring to?

That's the matrix table, so only available if the system is in matrix mode.

I'd get some screenshots but I'm nowhere near my car, and of course can't just open a saved map.

Here's the manual:

Page 15 starts the explanation of adjusting the fuel map.

Tx for the info. Starting to understand how the water, idle, crank and load maps work. Ordered secondary injectors from injector dynamics. Gonna continue tuning once they arrive.
