Hello chaps.

I have DTA P8 management on my RST.

The car has been mapped on a rolling road and runs loevely when up to temerature.
However, when started from cold it runs rather lumpy, i've tried adjusting the cold start enrichement but don't seem to be able to get it right.

Currently the readings are as follows.

Engine temp ~ Enrichement %
-10 ~ 300%
0 ~ 275%
5 ~ 250%
10 ~ 225%
15 ~ 200%
20 ~ 175%
25 ~ 150%
30 ~ 125%
35 ~ 100%
40 ~ 75%
45 ~ 50%
50 ~ 25%
55 ~ 0%
60 ~ 0%

Does anyone know what sort of figures are more appropriate? And do i need to alter the ignition timing relative to engine water temps??

Thanks for any info.

Matt.
