87 turbo 2 engine starts up great when at normal temp but when its cold it takes a little longer too start 550 primaries and 1600 secondaries,when it does just about start if you press the gas car falls on its face any ideas thanks,

 

mess with the water map

 

As mentioned, you will need to tune the water temperature correction map. Also, you'll likely have to add some cranking fuel in the CRANK map.

 

all fixed thanks

 

having the same probs guys

 

i used to have a hard start with my AEM EMS cuz im running the stock 850cc injectors (high impedance) and 1600cc (low impedance) . sold the ecu cuz i tot the ecu had a prob. Move to a microtech and still having the same prob...

 

Of course you're having the same problem. Both ECUs need to be tuned to your car.
