Hello to all.

I have a problem with VW Bora 2002 1.6MPI with ECU Siemens Simos 3.3 (inside C167 and 29f400). Car don`t have a normal cold start rpm. This ECU has 2 temperature sensors and they works ok, but after starting car do not up rpm above 800 (if coolant temperature not above 5-30 C). After warming of engine iddle speed rpm is in normal values (850-870rpm). I have tested ECU on the bench and not detected hardware problems. Anyone can increase cold start RPM in firmware (need set to 1300-1400 RPM)?

mate is not so simple to do that .. u want to change the RPM value at low ?C .. it's not the same like start maps . U have to check the RPM at low ?C with vcds or vas or any diag tool to try to find it in dump .

Thanks for advice, spawns3 (http://www.digital-kaos.co.uk/forums/members/92987-spawns3/)
I do not have experience in this work and if i will do it - i will do it very long . I need tested solution (damos or modified file), not for free.

Merry christmas and happy new year for all DK members!

Problem is still now and i can`t solve it myself.. I can only increase up cold start RPM value in adaptation chanels (not above 10% up) ,but if customer wants to disconnect battery, all adaptations will been lost. Therefore i search solution, how do it in flash. Anybody has a experience in tuning this ECU - VAG Siemens Simos 3.3?
