List your:

Factory rom Id
3d rom id
Map sensor
Map sensor scaling
Map:kpa table
Kpa : load
Injectors scaling and latency (include make aswell)
Reluctor wheel if known



My hopes are we can find a trend for the cars that cannot seem to get past start idle and die.

Help won't be immediate most likely. So this isn't a replacement for setting up your 3d rom thread .

 

Though SD works great on my car and a few others I have done, one issue I noticed was making sure the map sensor scalings are correct since not everyone is running a 3 bar sensor and not everyone is running a 4 bar.

What I noticed with one car was it started loping like it had cams and held vacuum at 8in/hg and after the engine warmed up would idle normal. After going through everything making sure it was all set up correctly just this one simple issue of not having the correct scaling selected caused the car to run fairly bad to start. On top of that it caused the fuel map and VE map to be off.

I know it may not help everyone who is having issues but it can help some as I totally overlooked it without thinking.
