Thanks for the quick response Norbs. I have had a cold start issue the few times I’ve been using my ms3 based system... the weather here’s been shitty so haven’t been able to work much on the car but I have been trying to read and learn as much as I can from reading the manuals and forums. (Also had some weird idle issues.) ...once the weather gets better I will start working on the car again but wanted to get different ideas on how people solved their starting/idle issues with aftermarket ECUs.Cold start is always tough, it took several adjustments of the cranking fuel , coolant , afterstart enrichment and IAC settings. Each combo is different so its very hard to put a generic setting in.
When you say warmed up you mean wait for reading to stop at 19?Basically you need to watch the o2 sensor readings as soon as it fires, and it will give you a clue about a few seconds after firing on what to do with the fueling. Provided you waited for the senor to warm up long enough before cranking and logging.
