Hi,
Please can you advise the functionality of the after idle enrich temp variables;

Forget the idle enrich parameters. I was using these to test new code found in the VL turbo ECU I have here. Now removed them

What they were for is that after the Idle Enrich table is checked there are various temperatures as well as counters used (counter reset on cranking)

Based on the temperature and time elapsed since startup affects the multiplication against the AI_ENRICH table used by the ECU

They should have been defined as:

symbol 0xBEFF AI_ENRICH_COOLANT_TEMP1
symbol 0xBEE4 AI_ENRICH_COUNTER_CHECK_LOW1
symbol 0xBEE5 AI_ENRICH_COUNTER_CHECK_LOW2
symbol 0xBEE2 AI_ENRICH_COUNTER_CHECK_MED1
symbol 0xBEE3 AI_ENRICH_COOLANT_CHECK_MED2
symbol 0xBEE6 AI_ENRICH_COOLANT_CHECK_HIGH1

As for the safety limits. when there is no speed then TP and RPM safety limits are used instead of the regular limits in the software (where applicable for TP)

ahhaa, the TP safety limits may have something to do with a VLT not making power after 5000.
no speed signal due to a gearbox swap not completed properly.

In that case you have to increase the TP and RPM safety limits (for when speed=0 all the time)
